Don’t Wait for Sparks: Common Reasons You Need a Residential Electrician

Electricity is installed early in the construction process. After the homeowner closes on the property and receives the keys, little thought is given to the electrical system again. Fortunately, residential electrical systems are stout and stable, so the reputation is well deserved. However, there are some reasons for homeowners to need an electrician, and it is important to know when to make that call. After all, a damaged or ineffective electrical system poses a danger to people and property, dangers from potential shock and fire.

Identifying Residential Electrical Issues: Four Reasons You Need to Call an Electrician

1. Outdated materials. If a home was constructed before the mid-1970s, you are probably acquainted with an electrician. Construction technology introduced some materials that no longer meet building code requirements. Materials, such as aluminum wiring and knob and tube wiring, pose a hazard to homes and should be removed as soon as possible.

Outlets with two prongs were phased out of construction in the 1960s and no longer met building codes. The first two prongs always carry electricity back and forth. A third prong was introduced as a safety feature, to carry a potential short-circuit safely away. If your home has outlets with only two prongs, they will need to be replaced.

Vintage homes may also have electric service panels with fuses instead of circuit breakers. Replacing these panels might be a practical measure since household fuses are getting hard to find. Keeping a supply of the correct fuses is necessary, but is becoming increasingly difficult. We recommend calling our residential electrician team to make updates or changes to your service panel.

1. Right-sizing the electrical service panel. The number of electronic devices and the current these devices draw have increased dramatically over the last few decades. Some residential electrical systems are being overwhelmed by the increased need. If circuit breakers trip frequently at your home, the capacity of the service panel may need to be increased. A 100-amp service has been typical since the 1960s, but this may not be a large enough service. A 200-amp service is more typical of larger homes, homes with many devices in use, or homes with special electrical needs.
2. Extension cord nightmares. Another indication of trouble is an inadequate number of outlets available for devices that seem to multiply daily. Extension cords, power bars, and outlet extenders are supposed to be temporary measures. When they are permanent fixtures, they cause a tripping hazard and a potential fire hazard. Too many devices plugged into a single circuit can lead to an overloaded circuit. Outlets or extension cords that are hot to the touch are indications of a dangerous overload.

Adding a circuit to handle the extra devices sounds easy enough, but if the service panel cannot accept another circuit, it may require a new service panel. A professional residential electrician is needed to make this determination.

1. Additional heavy equipment. Most new appliances and devices are designed to use less energy, not more. However, some homeowners are adding equipment to their homes that demands upgrades to the electric service panel and technical assistance from a professional residential electrician.

Whole-house generators are in demand to compensate for weather-related power outages. Adding a generator to a home is a complex process, requiring a transfer switch and a permanent generator installation.

Whole-house surge protectors are also a frequent addition to homes for the same reason—volatile weather patterns that threaten the integrity of a home’s electrical network and appliances.

Electric vehicle charging stations are being installed in homes as an everyday charging option. Charging takes significant energy, a dedicated 220-volt circuit, and a potential upgrade to the electric service panel.

Why Regular AC Maintenance Matters

Life in the Deep South changed for the better with the introduction of central HVAC systems. Before that time, warmth in the winter was achieved by burning fuels, such as wood or coal, making city air quite polluted. Tenement apartments in northern cities were stiflingly hot and stuffy. The heat and humidity of southern states would make such apartments deadly; there are not enough windows to ensure adequate ventilation.

This marvelous innovation depends upon gas chemistry and a chemical formula that absorbs and releases heat easily.

• Compressing a gas increases the temperature, and releasing the pressure of a gas causes it to cool. Releasing the pressure suddenly causes rapid cooling.
• Several complex gas formulas, collectively called Freon, are used because they freely absorb and discharge heat energy.
• Air conditioning is the process of moving heat from one space (indoors) and releasing it to another space (outdoors).
• This transfer of heat requires a rather precise amount of Freon in the network of tubes.
• Heat transfer is controlled by sensitive electronics that sense temperature changes and switch high voltage ON and OFF regularly.
• Heat transfer is hindered by dust and dirt at several points.

Why Regular AC Maintenance is Crucial for Your HVAC System

Regular AC maintenance is required to keep an air conditioning system functioning properly.

1. Air conditioning requires air movement inside the home. A large blower motor pulls all the air in the home through a network of ducts and funnels it through an air filter. The air may seem clean, but the filter collects dust, pollen, and many other airborne particles. When the collection gets too thick, the filter begins to hinder the air movement and makes the system work hard to cool the air at all. An AC maintenance plan will always include changing the filter at least every three months.
2. Cleaning will continue in the space just beyond the air filter—the evaporator chamber. This is the space where the tubes of cool gas encounter warm air from the house. Humidity condenses here and drips to a tray below and drains away. Since this space is often wet and may encounter dust that gets past the filter, it is thoroughly cleaned.
3. The outdoor air conditioner unit, the condenser, is also thoroughly cleaned. The central fan pulls a lot of air through the walls of the condenser to cool the tubes and release the heat. But pollen and dust collect here as well and need to be washed away with a garden hose.
4. The Freon pressure should remain constant year after year. Even a slight pressure drop usually indicates a leak, and since the gas is under pressure, the Freon will all leak away. Missing Freon prevents cooling and can cause catastrophic failure of the entire system. Checking the pressure is an important task in air conditioner maintenance.
5. The whole of the chemical/mechanical process is controlled by sensors, switches, and control mechanisms. These electronics function with a variety of currents, some at 220 volts, some at 110 volts, and some at much lower currents. The thermostat runs on battery power. This complicated control system requires specialized equipment and the training necessary to distinguish between current levels.
6. The last and most important function of AC maintenance is a check of the cooling function. The thermostat setting should call for a cooling cycle. The cooling cycle should result in cool air coming from the supply vent. The air should be within an acceptable temperature range to indicate proper cooling.

Home Generator Installation in Houston: Don’t Wait for the Next Outage

Since the last few years have demonstrated a bit of chaotic weather, many Texas homeowners have been led to again consider the purchase of a whole-house backup generator. Few people have even basic knowledge of the workings of generators; for this reason, many people put off the decision to obtain a generator until the next major weather event. Here are some interesting facts about generators that might help you with this decision.

Reasons for a Home Generator Installation

The obvious reason to purchase a backup generator is frequent power outages. But the reasons for outages have increased over the years.

• Since hurricanes feature both high winds and heavy rain that lead to flooding, they can cause widespread damage to utility infrastructure above and below ground. Recovery to the electrical grid can take weeks, sometimes even months, leaving your family without power and vulnerable.
• Localized thunderstorms, tornadoes, and straight-line winds often result in localized severe damage, especially to the power grid. The recovery time depends on the damage, but you can count on days or weeks without electricity.
• Although it happens infrequently, the chaotic weather recently has included ice storms that resulted in power outages. It is admittedly rare, but it can be just as dangerous as other weather events.

Home Generator Installation Timing

Everyone in Houston knows that hurricane season lasts from June until November; the largest number of hurricanes make landfall during these months. This season is also the period of peak interest in generator purchases. A few years ago, supply chain problems led to a shortage of available generators during the hurricane/peak purchase season, but the economy and supply chain have recovered. It should not be a problem to find a generator for your home. However, the peak season may overwhelm the number of qualified contractors who can install the generator.

The Home Generator Installation Process

The installation process goes way beyond the initial purchase; it will include these steps and maybe more.

• There is some consultation with electrical professionals to determine which circuits on the service panel will be powered by the generator. This will determine the size of the generator—measured in power output in wattage. Do you absolutely need to empower every circuit? Which circuits could be isolated and not empowered? This will help determine the size of the generator needed for your home.
• Is the existing electrical service panel in your home compatible with the generator connections? If not, a generator will require an added step.
• The generator will require a transfer switch installation. The transfer switch automatically breaks the connection with the power grid whenever the generator is engaged. This prevents the power from the generator from reaching repair crews working to restore power or the neighbors’ homes who are not expecting their homes to be empowered.
• The installation of the generator requires some planning. It requires permanent installation of the generator at least 20’ away from the home (to prevent exhaust from entering the home). If the generator is powered by natural gas, it will need to be connected to the gas utility. If the generator is powered by another fossil fuel, installation should include a safe fuel facility.
• The generator will require maintenance, filter changes, and schedules of activation to ensure it is ready for an emergency.

If a Home Generator Installation is in your future, give yourself some time.

Home Generator Installation: Our Essential Homeowner’s Guide

There is an increasing need for home generator installation in Texas due to frequent and severe weather-related power outages. We recommend these crucial steps involved in home generator installation, from determining power needs and compatibility to proper placement and maintenance. We advise homeowners to plan their purchase and home generator installation well in advance of peak storm season to avoid delays and ensure preparedness.

HVAC Lifespan: What You Need to Know for AC Replacement

Will this be the year that you replace your heating, ventilation, and air conditioning (HVAC) system? Many people will. A few people will replace their system as part of a repair or remodeling project. The remaining people in this category fall into two categories:

• Homeowners who know the age and condition of their HVAC system, and are making plans to replace it on schedule.
• Homeowners who are not aware and assume their HVAC system will last indefinitely.

Facts About Aging and How They Affect AC Replacement

• Central heating and air conditioning systems have been around for a long time. The technology was deemed stable and the cost was affordable in the ‘50s and ‘60s.
• A whole branch of engineering has developed around HVAC systems. Some engineers do research and others design equipment.
• Manufacturers have developed quality components and have a tremendous reputation for excellence and longevity.
• The US Environmental Protection Agency and Department of Energy regulate various aspects of HVAC manufacturing and installation.

The experience and expertise of these professionals agree that the average heating components have a useful life of about 20 years and the average air conditioning components have a useful life of about 15 years. Keeping these systems well-maintained often adds another five years to these components. These are statistical averages and not absolute deadlines, but they bear up over 65 to 75 years.

Aging Sequence and How It Affects AC Replacement

Research and experience also reveal a predictable aging sequence that homeowners can follow.

• The first ten years will pass without much problem. Energy efficiency will be at a maximum for the system and few repairs will be needed. Since all is well, it is easy for homeowners to neglect maintenance and regular filter changes. However preventative maintenance cleans vital parts and checks various systems. If a problem does develop in the first decade, it is generally small; routine maintenance will catch small problems before they become large problems.
• Years 11 to 15 continue to be relatively problem-free, but observant homeowners may detect a loss of efficiency. This can be distinguished from rising energy prices by checking the kilowatt-hour use or volume of natural gas used in the same month year after year. It is also common to need some minor repairs during these years. Again, catching them during routine maintenance is much better than when the system breaks down since a breakdown is apt to happen at the most inopportune time.
• Years 16 and beyond will likely be marked by further loss of efficiency and a greater potential for needed repairs. At some point, a major component will need to be replaced because of predictable wear and tear. The cost of repairing an old system can rival the cost of a complete replacement.

If you do not know the age of your HVAC system, the information is readily available. Find the Model/Serial number plate for any system component. HVAC manufacturers’ websites can take this information and ascertain when the equipment was manufactured and give a relatively accurate determination of when it was installed.

This information, combined with the research and experience of mechanical engineers, offers homeowners a wealth of information to help them make decisions concerning when to replace their system. Planning a replacement is much preferred to waiting for a sudden and unexpected catastrophic failure, with an emergency replacement.

Your AC Replacement Guide: Age, Efficiency, and Planning

Air conditioning units’ lifespan averages about 15 years and heating around 20, emphasizing that proper maintenance can extend these timelines. The aging process, from peak efficiency in the first decade to increasing repair needs and efficiency loss in later years, advises proactive AC replacement planning over emergency breakdowns. Homeowners are encouraged to determine their system’s age using model/serial numbers and consider replacement before significant failures occur.

High Winds vs. Your Furnace: Common Problems and the Furnace Repair Solutions

Winter has been brutal this year. And you don’t want to be caught in the cold due to furnace repair. Polar vortices have pushed cold weather south and strong winds into the deep south, four times in December, four times in January, and twice in February. New Orleans and Pensacola have seen snow this winter and Dallas saw single digits in February. Houston saw cold and snow that was driven by strong and violent winds.

Did you know that high winds can interfere with furnace function? Perhaps you experienced these problems without knowing. Here are some furnace repair problems to watch for during periods of wintry high winds.

1. Aging Caulking. The fine point of insulation is accomplished by caulk and weatherstripping. Caulk begins as a paste, filling in very small cracks and blocking the wind from entering the home. Time and weather cause the caulk to harden and as it does, it pulls away from surfaces. Although the gaps are very small, the wind gets in and can make indoor spaces uncomfortable.

Discovering drafts can be accomplished with a candle or an incense stick. Bring the flame or smoldering incense stick close to the windows or door jams. Gaps will need to be re-caulked. Larger gaps can be filled with weatherstripping.

1. Natural Gas Flues. When natural gas burns, the exhaust—mainly carbon dioxide and water vapor—is released outdoors through an exhaust pipe called a flue. When the wind is high in the winter, a pressure imbalance can occur, delaying the release of the gas into the atmosphere. This imbalance causes exhaust gas to temporarily back up into the home. (For this reason and more, it is important to keep a carbon monoxide detector in every home with a natural gas furnace.)

The flue should extend higher than the peak of the roof to ensure the exhaust is blown away. If the problem persists, it may require a windbreak. This technology is very exacting and must be completed by an experienced HVAC technician.

1. Natural Gas Ignition. Between the pressure imbalance and drafts, high winds can affect the ignition system of a gas furnace. Old furnaces might still have a pilot light, and the light will need to be re-lit. Winds can blow the pilot light out, preventing ignition as needed. Newer furnaces have an electric ignition system, but drafts and imbalances can prevent ignition.

Solving the draft and pressure imbalance will solve the ignition problem.

1. Dirty Air Filters. Snow is only a part of the problem. High winds can pick up any dust or debris, increasing the number of airborne particles. This can add to the collection of dust on the HVAC air filter. Whenever a filter is covered, it restricts the airflow and interferes with proper heating. A clogged air filter is a very frequent reason for repair calls for HVAC systems.

The solution, of course, is to change the air filter regularly—at least every three months.

Let AirPro Houston Help You Combat Wind-Related Furnace Repair Issues

By understanding the impact of high winds on your furnace, you can take proactive steps to maintain a warm and safe home during harsh winters. Regular maintenance, including checking for drafts, ensuring proper flue function, and changing air filters, is essential. For complex furnace repair issues like windbreaks or ignition problems, consulting with a qualified HVAC professional at AirPro Houston is crucial. Don’t let winter winds compromise your comfort; address these potential problems to keep your furnace running efficiently.

Level Up Your EV Charging: A Guide to All Your Residential EV Charger Options

The idea of purchasing an electric vehicle (EV) is very appealing, but only if the owner can navigate the charging issue.

• A complete and diverse infrastructure is available for internal combustion engines: there are gas stations, convenience stores, and truck stops available at many locations.
• However, this type of charging infrastructure is not available for EVs. Who is responsible for this infrastructure? Should it be the electric utility provider? Should it be commercial entrepreneurs? Should a government entity install the infrastructure?

A fear associated with EV use is running short of charge while on a trip. To avoid this, an EV owner needs to develop a clear charging plan, including emergency charging options. First, EV owners need to clearly understand all of the charging options. Second, they need to identify charging stations in convenient places to meet any charging needs.

Level One Residential EV Charger

Every EV comes with a Level One charging cord, which amounts to an extension cord for the car. There are some important pros and cons about Level One charging.

• This charger uses a normal 110-volt circuit, found in every home and commercial space. There is no lack of places to charge an EV with Level One charging. A Level One charger is an option for emergencies and for when the EV will not be used for a while.
• Level One charging is the slowest form of charging. It can take 24 hours for an EV to go from empty to complete charge.

Level Two Residential EV Charger

A Level Two charging station is typically installed in a garage or secure location. The charging station is connected to a dedicated 220-volt circuit, ensuring that a quick charge can happen without interruption.

• Charging is much faster—Level Two charging usually takes 6 to 8 hours from empty to complete charge. That allows EV owners to charge overnight with no problem.
• Charging is convenient and done in a secure location.
• A Level Two charging station and the installation are an additional cost. Make sure to allow time to schedule the installation.

Level Three Residential EV Charger

A Level Three charging station is a commercial, high-speed charging station, usually located in public spaces, frequented by shoppers.

• Level Three charging is very fast—from empty to complete charge can take as little as 30 minutes.
• Level Three chargers can be used to travel across the country. A relatively quick stop for a charge and the trip can continue.
• Level Three charging is the most expensive form of charging. Charging costs depend upon the level of charge needed and can cost $30 or more.
• The number of available Level Three charging stations is growing, but the total number of stations is still very low. There are only 20,430 such stations across the US; most are located in a very limited number of locations.

EV owners must retain every charging option to ensure charging is available upon demand.

• The Level One charging cord should be always stored on the vehicle in case of emergency.
• A Level Two charger should be considered and installed if possible.
• Know the location of every Level Three charging station in the vicinity. Locate quick-charge stations on the route of long trips.

Let AirPro Houston Help You Overcome Your Residential EV Charger Anxiety

There are three levels of EV charging, from the slow, ubiquitous Level One using standard outlets to the fast, but less common and more expensive, Level Three commercial stations. It emphasizes the importance of understanding each level and developing a charging plan to mitigate range anxiety. For residential charging, a Level Two Residential EV Charger is recommended for faster, overnight charging, while Level One serves as a backup and Level Three is best for long trips.

Commercial HVAC System Lifespan: A Guide to Commercial HVAC Maintenance, Repairs, and Replacement

Heating, ventilation, and air conditioning (HVAC) systems are very common building components, with typical characteristics, and predictable similarities. Your HVAC system is only distinct because of the importance it plays in the health of your customers and employees, safety, and comfort. An objective look at an HVAC system reveals these similarities. 

Commercial HVAC Maintenance: The First Ten Years

When an HVAC system is installed, it is sized for the space and features of the building it is installed, using a Manual J load calculation. Sizing computations are used for both the heating and cooling functions needed in the regional climate. Manufacturers offer nice warranties that help should there be a manufacturer’s defect.

HVAC systems require maintenance. Many business owners skip this, but thankfully you are keeping your system well-maintained.

• Maintenance includes cleaning important areas that are not generally visible. But keeping the coils clean is vitally important. The air filter will be replaced; we strongly encourage you to change the filter every three months.
• During the maintenance visit, our technician will test refrigerant levels and test sensitive electrical components.
• A technician will test the system’s performance and determine whether the thermostat is functioning properly.

A well-maintained HVAC rarely encounters problems while relatively new.

Commercial HVAC Maintenance: The Second Ten Years

The average HVAC system functions adequately for about 20 years: the air conditioning portion lasts slightly less than the furnace components. Even with regular maintenance, wear begins to develop. In 20 years, most HVAC systems will have between 350,000 and 500,000 five-minute cycles. Age and use take their toll on electrical and mechanical parts; this has less to do with maintenance and more to do with use. In the second decade, expect to see, hear, and feel a few different sensations with an older HVAC system.

• Natural gas flames should be blue. If the furnace flame is yellow, it indicates incomplete combustion and a problem with the burner assembly.
• An aging HVAC system may sound a little different—normal sounds may become louder or new, and unusual sounds may develop. Listen for buzzing, grinding, or clanging sounds.
• The blower motor should be collecting air from the targeted space, conditioning and cleaning it, and recirculating out of the system again. Any smell—burning or musty smells for example—indicates a problem.
• If the HVAC system is not keeping your business at the desired temperature, it indicates a problem is developing.

It is not unusual for repairs to become necessary during this period. Hopefully, the repairs can be identified during regular maintenance visits. A small problem can be caught early before it develops into something bigger.

Commercial HVAC Maintenance: Big Ticket Repairs

Proper maintenance, changing the air filter regularly, and just-in-time repairs can add years to the HVAC system’s usefulness. But eventually, age and wear catch up to the vital parts. When larger components falter or fail, the cost of replacing parts rivals the cost of replacing the system. At this point, a decision needs to be made concerning the replacement of the entire system. Some of those high-cost components include:

• The compressor unit. The outdoor air conditioner component is called the compressor unit, and it has two major parts—the compressor motor and the network of cooling coils. Both the parts and the installation of the parts can be very expensive.
• A byproduct of burning natural gas is water vapor, a catalyst for rust on cast iron and sheet metal. When rust corrodes completely through burner assembly or heat exchanger parts, replacement can approach the cost of furnace replacement.
• Losing the refrigerant gas from an air conditioner or heat pump system used to be a simple process, but now it can be cost-prohibitive. Some refrigerants are no longer available. Some refrigerants are available but no longer being manufactured, so the law of supply and demand makes them increasingly expensive.

When a business owner understands the limitations of the HVAC system, a replacement plan can be implemented to prevent the dreaded emergency HVAC replacement.

The 3 Stages of Your HVAC System’s Life and How HVAC Maintenance Affects Each Stage

Commercial HVAC systems generally last around 20 years, though lifespan can vary depending on maintenance and usage. During the first decade, regular maintenance is key to preventing major issues, while the second decade often sees increasing wear and tear and the need for repairs. Eventually, major component failures make replacement more cost-effective than continued repairs, necessitating a planned approach to avoid emergencies.

Charging Ahead: What You Need to Know About Residential EV Charger Installation

Isn’t the New Year exciting? Most new things bring change and potential. It can be a favorite time of the year. If your new year includes the potential of an Electric Vehicle (EV) purchase, it will definitely bring change into your life. Preparing for the change is essential to making it a GOOD change, so buckle up and get ready.

First, appreciate being able to pass up the gas stations and oil change bays. A stop at the corner convenience store can be for a soft drink and a quick snack without a fuel purchase. The substitute, however, will be learning to charge your EV regularly using a variety of charging options. Currently, there are three charging options, and the average EV owner will need to use all three from time to time.

Residential EV Charger Installation Fact 1

Level One charging uses a standard cord with an adapter to charge your model of EV. The good news is that it can plug into any standard 110v outlet, so an EV can be charged from about anywhere. The drawback is this type of charge takes a long time to get from 0% to 100% charge—usually about 24 hours. This charger cord comes with the vehicle at no cost. Some will draw more energy than others, but they still only require a normal wall outlet.

Residential EV Charger Installation Fact 2

Level Two charging requires a 240v outlet, like the outlet used for electric dryers or stoves. This is like having a fuel station inside your garage; Level 2 charging takes about 6 to 8 hours for a 0% to 100% charge. Installing a charging station is not a DIY project, but it costs no more to charge than the Level One charging option. Make sure to purchase the charging connector that matches your EV’s specifications.

Residential EV Charger Installation Fact 3

Level Three charging happens at commercial charging stations. They are the most similar to gas stations for internal combustion engines. These stations can be found near shopping centers or other heavily traveled areas; a full charge—from 0% to 100%–can be delivered in about 30 or 40 minutes. Expect these options to cost about as much as filling a gas tank. But, they are available for travelers, emergencies, and as a convenience.

Remember, repeatedly letting a battery pack drain to 0% or to be charged to 100% is not recommended by EV manufacturers. Normal usage will allow EV owners to develop charging habits that will enhance the battery life of the vehicle.

If available, most EV owners prefer Level Two charging over the life of the vehicle (which can exceed the lifespan of internal combustion vehicles). Installing a Level Two charging station in a garage takes some planning and comes with a cost. Here are some essential residential EV charger installation reminders to prepare for:

• The Texas electrical code requires a professional electrician to pull a permit for the installation of a Level Two charger. This will require a plan, installation, and inspection by a code enforcement officer. This is not a DIY project.
• Since a Level Two charge pulls 240v, it must have a separate circuit devoted only to the charging station. This may require an upgrade of the electrical service panel to accommodate the new circuit and the heavy draw.
• All EV connections are not the same, so make sure to purchase the appropriate charging station for the chosen EV.

Charging will not be an everyday occurrence for most drivers, since a full charge gives an EV a range between 200 and 400 miles. A full charge on a Level Two charger will cost between $11 and $15 for most Texas locations.

The Federal incentive for purchasing an EV comes in the form of a tax credit, not an upfront down payment. Information for this incentive can be found at the IRS.gov website.¹ Incentive details have changed, so make sure that the details are clear. Other state and local agencies may also have financial incentives, so complete your research.

Residential EV Charger Installation by AirPro Houston

As you consider purchasing an Electric Vehicle (EV) in the New Year, it’s important to prepare for the shift from gas stations to learning how to charge your vehicle using different methods. There are three main charging options: Level One (standard outlet, slow), Level Two (240v outlet, faster), and Level Three (commercial fast chargers). Additionally, a Level Two Residential EV Charger Installation in your home requires professional installation, and there are potential tax incentives to help offset the cost of purchasing an EV and the costs associated with residential EV charger installation.

Furnace Maintenance Checklist: Signs Your Heating System Needs North Houston Furnace Repair

Before the cold weather arrives in earnest, a checkup can ensure the furnace is healthy and ready for the heating season. Before you call the HVAC professional, it might be a good idea to collect problematic symptoms to help with the diagnosis.

North Houston Furnace Repair

Do You Hear Unusual Noises?

Over time, families get used to the sound of the heating and cooling cycles; few people can tell how many times the system comes on per hour. When family members begin noticing heating cycles, it is time for some North Houston Furnace Repair professional help.

• Banging noises can be serious! A dirty gas burner can trap natural gas momentarily. When the gas pressure releases the fuel there is a mini explosion, a bang to begin the heating cycle.
• Grinding or screeching noises usually mean one thing—wear in the blower motor. A powerful motor turns a fan that moves an enormous amount of air, and when the bearings lose lubrication, it makes a terrible racket.
• Electrical parts often make a loud humming or buzzing noise before they fail. Consider these noises warning for trouble to come.

Take the Temperature

The thermostat includes a very sensitive thermometer that measures the air temperature in the immediate vicinity of the thermostat. The thermostat setting and the temperature reading should match:

• When the temp drops below the setting, it should trigger a heating cycle.
• When the temp reaches or rises above the setting, it should end the heating cycle (there will be a few seconds delay before shutting off to ensure the residual heat is transferred to the home).

If the temperature is below the setting by a few degrees, and the heating cycle has not been triggered, change the batteries and try it again. If not, call for some HVAC help.

If your investigation uncovers new hot spots–rooms or spaces that are colder than the rest of the home, it should also be addressed by a professional. If the whole house is cold because the furnace is producing insufficient warm air, don’t panic. First, check:

• The air filter. A clogged air filter can restrict the flow of air through it. Change the filter and determine whether it fixes the problem.
• The thermostat. Someone might have bumped the setting to a low setting and forgot to bump it up again.
• The thermostat/heat pump setting. Heat pumps are very efficient since they draw heat from the outdoor air. If a cold snap pushes the outdoor temperature too low (below 32-35⁰) there may be insufficient heat to keep the home warm. Push the setting to AUX or EMG heat and see whether this fixes the problem.

New Smells

Neither the furnace nor the air conditioner should produce a smell since it will be circulating the indoor air. If an odor is coming from the HVAC vent it indicates a serious problem that needs to be addressed. However, one smell should produce a more urgent response.

If you smell gas inside the home, the family and home are in imminent danger. If you smell gas, take these steps immediately.

• Evacuate the family from the home before taking further steps. Do not make a phone call inside.
• Leave one or two doors open.
• When the gas dissipates, enter the home and shut off the gas supply.
• Step outside and call for immediate assistance from an HVAC professional or a gas utility company.

Gas utilities add a chemical additive to natural gas to alert people of its presence. The sulfur smell associated with natural gas is no joke. Natural gas can asphyxiate residents AND it is explosive, so do nothing that might create a spark.

North Houston Electrical Repair: Essential Electrical Upgrades for Aging Homes

Since the housing bubble burst in 2008-2010, construction of new homes has slowed dramatically, and that means the current stock of homes is aging quickly. The average age of homes in the US is about 40 years old and in Texas, the average is above 30 years old.¹ That means that statistically, very few existing homes were constructed with knob and tube or aluminum wiring. But Americans have drastically changed the way they use electricity in homes and not every home has been updated to match the demands. Which of these upgrades have you made? Which are on your to-do list?

North Houston Electrical Repair Tip 1: Too Few Circuits

The number of electronic devices used in the average home has radically grown in the last 40 years. It is not uncommon for homes to have multiple “power strips” designed to increase the outlet capacity. We employ them as surge protectors, but they become permanent extension cords that increase the number of devices plugged into a single outlet, an unsafe practice.

Most homes could use more circuits to accommodate the increase in electronics needed in a designated space. Also, do some research to ensure that surge protectors are used properly to protect sensitive devices.

North Houston Electrical Repair Tip 2: Assimilation of Smart Technology

Are you ready for Smart home technology? Smart devices extend well beyond cell phones. Thermostats, lights, home security systems, and lighting can be controlled by a phone, tablet, or with voice recognition devices. Coffee can greet the family automatically, ready for family members to move about their daily routine. Benefits include energy efficiency/cost savings and improved home security.

Most of the transition to Smart technology involves programming software. However, it may require some wi-fi signal boosting to increase connectivity.

North Houston Electrical Repair Tip 3: Surge Protection

Early on, folks used power strip-type surge protectors to shield electronics, such as computers and TVs, from electrical surges that happen during localized lightning strikes. However, power surges happen more often than lightning strikes; each power disruption and restoration also creates power surges. Power strips provide limited protection since each surge reduces the protection. Beyond that, every device in the home is subject to power surges.

A whole-house surge protector can be installed between the power grid and the electrical service panel to protect the entire home from voltage spikes. Protection will prolong the life of the home’s electrical devices and prevent damage to the home’s electrical wiring.

North Houston Electrical Repair Tip Tip 4: Lighting Upgrades

A direct benefit of energy conservation has been the development of energy-efficient lighting. After several iterations of lighting design, the most recent improvement has led to light-emitting diode (LED) technology. Incandescent lights send electricity across a metal element. The primary result is that most of the energy is spent creating heat and light is only the secondary result. LED technology is 75 to 90% more efficient than incandescent bulbs. Since LED lights produce very little heat, they tend to last longer—some bulbs will burn for a decade before needing to be replaced.

The variety of bulbs is also astounding. Whether you prefer white light or softer golden light, bright light, or softer luminosity, there are bulbs to match your preference. Also, lighting changes can be done gradually as incandescent bulbs need to be replaced.

North Houston Electrical Repair Tip 5: EV Charging Stations

Electric vehicle owners will probably use all three charging methods available to EV owners during their very long life. The most convenient charging method is currently a home charging station; if you anticipate an EV purchase this needs to be a part of the discussion.

Charging stations carry 220v through a circuit dedicated to charging the EV and should be installed by a professional electrician.

North Houston Electrical Repair Tip 6: Electrical Service Panel Upgrades

If your home needs new circuits, surge protection, and potentially an EV charging station, chances are that you also need to upgrade your circuit panel. A new panel can accept an increased power load from the grid and distribute it safely. This will ensure your home keeps up with the demands of technology and provides a safe environment for your family for years to come.

North Houston Electrical Repair – Meeting the Demands of Modern Technology

As homes age, many are ill-equipped to meet the growing demands of modern technology. Common upgrades include adding circuits to accommodate more electronics, integrating smart home devices for convenience and efficiency, and installing whole-house surge protection to safeguard electronics. Additionally, energy-efficient lighting, EV charging stations, and electrical panel upgrades can ensure homes are safe, efficient, and ready for the future.

Furnace Replacement Signs For Homeowners

There are two difficulties homeowners face concerning keeping their heating, ventilation, and air conditioning (HVAC) systems running as long as possible.

• Time/wear and tear
• Regular maintenance

The homeowner cannot do much about the wear and tear, but they should do something about the maintenance. When a small problem occurs, scheduled maintenance will usually catch it and repair it before it becomes big. When does a problem become too big? How can one know it is time to replace the system instead of repairing it again? These are the major things to watch for: when these issues compound, it is time to replace the system.

Furnace Replacement Sign 1: Age

Most people have a threshold for how long they intend to keep a vehicle. Maybe it is a mileage mark or perhaps serviceable years, but this benchmark determines choices concerning the car or truck you drive. Homeowners might take this approach concerning their HVAC system instead of leaving everything to chance.

After 70+ years of experience, we know that air conditioners function for 15 to 20 years and furnaces for about 20 years. It is also evident that good regular maintenance can add years of usefulness to HVAC components. While some systems might last longer, they will not last much longer than that. It is unreasonable for homeowners to plan for their HVAC system to run indefinitely.

If you are unsure of the age of your system, the manufacturer’s website can give you clues by supplying the manufacture date. Find the serial/model number and make inquiries.

Furnace Replacement Sign 2: Poor Indoor Air Quality

An important function of the HVAC system is to clean airborne contaminants from the air to provide fresh, clean air to circulate throughout the home. If the system cannot clean the air properly, if dust covers many surfaces, it may indicate a deeper problem. First, check the air filter. A clogged filter may let dust and dander pass around it. Next, check the vent and return covers: if they are very dusty, the problem needs to be addressed.

Dust, dust mites, dander, pollen, and mold spores often trigger allergies and asthma. Bacteria and viruses can lead to other illnesses. If your system does not clean the air properly, it may need to be replaced.

Furnace Replacement Sign 3: Unusual Sights and Sounds

Homeowners can often sense something “not right” with the HVAC system. Normal sounds might become louder, or the quiet system now begins to make unusual noises, such as screeching or grinding. These are not good! You may hear the heating or cooling cycle run much longer than normal. This is not good!

The system should not produce a smell at all. There might be a scent for a short time as the furnace burns dust off the elements when the furnace starts up for the first time, but there should be no further smells. A musty smell during the heating season may indicate an open duct, allowing (cold) moist air into the home. A hot or burnt plastic smell indicates a potential electrical problem.

Furnace Replacement Sign 4: Cost Increases

Look in two directions for increases in the cost of heating and cooling. First, check the utility bills, not for an increase in cost, but an increase in energy use—either an increase in kilowatt-hours or cubic meters of natural gas. The cost of energy might be higher, but an increase in energy use indicates poor efficiency.

Also, look at the accumulation of repair bills over several years. Each repair might not be excessively high, but the total of the repairs might be staggering.

The aggregate of these indicators will lead you to a decision about replacement. Eventually, a repair will be so high that further repairs are no longer cost-effective, and replacement is the best option.

AirPro Houston’s Furnace Replacement Guide for Homeowners

As a homeowner you should be aware of signs that indicate it may be time for a furnace replacement, such as its age, declining indoor air quality, unusual noises or smells, and increasing energy costs. While regular maintenance can extend the life of HVAC systems, certain issues like poor efficiency and escalating repair bills signal the need for a furnace replacement. Knowing these warning signs can help homeowners make an informed decision about when to replace their furnace to avoid costly repairs and health risks.

Is It Time for a Furnace Replacement? Key Warning Signs You Shouldn’t Ignore

Seasons flow and change so quickly; the Holiday Season is already upon us. Can you believe it?

In days gone by, Texan’s lives were tied to the agricultural seasons—planting, cultivating, harvesting, and resting. Since we spend the vast majority of our time indoors, it is more accurate now to tie our lives to two seasons—the cooling and heating seasons. We depend on our HVAC systems year-round, so it is important to keep them running smoothly.

If your attempts to keep your system running smoothly are not going as smoothly as hoped, it may require some further investigation. To help your investigation, here are a few questions to determine whether your HVAC problems are serious or not.

Furnace Replacement Warning #1: Determine the Age

If you did not install the current furnace and do not know the age, take a picture of the serial number tag. Enter the model/serial number onto the manufacturer’s website to uncover the date and year the system was manufactured. It will not uncover the date of installation, but it will be close.

HVAC systems have a limited lifespan. Expect a range of 15 to 20 years. A system may continue to function beyond this, but problems will develop. At this stage, it is best to plan a replacement date and budget for replacement.

Furnace Replacement Warning #2: Use Your Senses. Start with your sense of smell

If you have a natural gas or propane furnace and smell rotten eggs or sulfur, the situation is dangerous, evacuate the home immediately. Call the gas company from outside the home. (Natural gas is odorless and colorless, so the gas companies add a chemical marker to identify leaks.)

If you smell a musty smell, it may indicate a leak in the duct network, allowing either stale air or moisture into the ducts. This musty, unhealthy smell is spreading throughout the house and needs to be repaired quickly.

Use your sense of hearing.

The system should continue to sound normal until it doesn’t. As a system ages, normal sounds may get louder. Electrical control mechanisms may hum or buzz loudly. The one moving part—the blower motor—may become worn and begin screeching or grinding. These sounds are serious and need to be addressed.

Take a careful look.

If your furnace is natural gas-powered, observe the burner assembly during operation. The flame should be blue; a yellow flame indicates incomplete combustion. This is a waste of energy, producing dangerously high amounts of carbon monoxide. The gas is being exhausted to the outside, but it is bad for the environment.

Furnace Replacement Warning #3: Look Deeper into Performance

Collect utility bills for consecutive months over a few years. Ignore the cost for now but check the kWh usage. It is not unusual to see slight increases, but a large consistent increase in electricity usage (without adding a new energy-using device) can indicate a weakening system.

If heating cycles tend to run unusually long (or if you consider raising the thermostat setting way too often), it may indicate the system is running weak. The same is probably true of the cooling cycles—not keeping up with comfort.

Also, look at the frequency of repairs and the cumulative total of the costs. This number will be interesting the older the system becomes. Eventually, this figure becomes surprisingly high and replacement becomes financially viable.

Common Residential Electrical Repair Issues for Homeowners

When do minor annoying electrical blips become problems or, worse, dangerous issues that need to be addressed? Understanding why these things happen will help homeowners determine whether the problem can be overlooked or needs to be investigated.

Residential Electrical Repair Problem 1: Intermittent Switch Function

Normal usage of light switches over the years causes the mechanism to wear and become loose. When the mechanism wobbles, the contact does not connect or stay connected, and the light may blink intermittently. The switches that are used the most will be worn first; since the original switches were installed at the same time, it is common to see several switches fail together.

Some outlets are connected to switches so that several lights can be turned off at once. If the switch is bad, these outlets may not work properly.

These switches cannot be repaired, they will need to be replaced. The intermittent connection can cause a short, so don’t overlook this problem.

Residential Electrical Repair Problem 2: Dimmer Switch Malfunctions

Dimmer switches are a little more complex. There are often two components—an ON/OFF switch and a dimmer slide or knob. If the dimmer mechanism is not working, check to make sure the switch is ON. Both switch and dimmer have mechanical parts that can be worn. Both will need to be tested. If either portion of the dimmer switch is worn, that portion should be replaced.

Not all lights are designed to be dimmed, so if the light does not fully dim or flickers, the bulb may need to be replaced with one that is compatible with a dimmer switch. Find this information on the light bulb label. Continuing to use a non-compatible bulb will lead to premature bulb failure.

Residential Electrical Repair Problem 3: Shock From Devices

During the winter, it is not unusual to walk across the carpet, pick up a static electric charge, and get a slight tingle when touching a switch, person, or metal object. However, if someone is receiving an electric shock beyond static electricity, it is a serious problem.

Electricity is composed of a stream of electrons flowing through conductive substances. Household electricity should be contained in a wiring loop; when it escapes, it is a problem. Even though people are made of conductive substances, it is not good for us to be a part of the circuit. It could be the device. It could be the wiring. But even minor shocks need to be investigated, and the problem repaired.

Residential Electrical Repair Problem 4: Dimming Lights

If lights dim when a major appliance, such as a kitchen range, is in use, it indicates a momentary overload of the circuit. This can also happen in a room with too many devices plugged into a single circuit.

If the overload is limited to a matter of a second or two, it needs to be addressed but is not an emergency. During a renovation or while having electrical work completed, it would be best to move some of the devices/outlets from the circuit and create a new circuit.

Residential Electrical Repair Problem 5: Intermittent Failure of Recessed Lights

Can lights that are recessed into the ceiling and surrounded on all but one side. They need to be installed with plenty of room to dissipate heat, but if they are improperly installed the heat may build and overheat the fixture. When the fixture overheats it does pose a fire hazard, so, even though it may be a pain, this installation needs to be corrected.

Residential Electrical Repair Problem 6: Circuit Breakers Tripping

Distribution wires carry extremely high voltage or electric pressure. Transformers reduce the voltage so that when it enters a home, the current is manageable. The whole home may receive 150 to 200 amps; individual circuits take only a portion of the current, usually 15 amps or so. When homeowners try to draw more than 15 amps through the circuit or when a short pulls additional amps, the circuit breaker is designed to trip to break the circuit and stop the flow.

A circuit carrying too much current is in danger of overheating. This can lead to damage to devices, melting of wires or connectors, and can lead to a residential fire. A short can cause a serious (even deadly) shock or ignite combustible material and start a fire.

Call the Residential Electrical Repair Experts at AirPro Houston

Problems like intermittent switch functions, dimmer malfunctions, and electric shocks can indicate underlying issues that need immediate attention. Additionally, issues such as dimming lights, recessed light failures, and tripping circuit breakers should be addressed to avoid potential hazards like electrical fires or device damage.

Get Ready for Winter: Essential Furnace Maintenance Tips for a Cozy Home

The temps will be dropping soon, and the heating season will begin. In the meantime, we can expect a few days that require both air conditioning and heating on the same day. The mildness of winters in this region makes the weather less extreme than summers, but they still require heat on most days to make a home comfortable. Here are a few furnace maintenance approaches that can make a home very comfortable and still save money on utility bills.

Use Solar Gain

The sun is the greatest source of free heat in the entire solar system and with a little effort, it can be used to the best advantage during the winter. The insulation in a home is installed to create a thermal barrier to keep the heat inside and the cold outside (or vice versa during the cooling season). However, windows are very poor insulators and allow heat to move freely through them. This can increase comfort in a home if you want to take advantage of the sun.

• Determine which windows are on the south side of the house. These windows will allow the maximum amount of sunlight into the home.
• Opening window coverings on sunny days can increase indoor temperatures in the home by ten degrees.
• Remember to close the blinds/drapes in the evening, since heat will travel readily through the glass to the outdoors.

Insulate and Caulk

While insulation creates thermal and moisture barriers, caulk is a sealant that blocks air movement through small gaps, especially around doors and windows. Both measures reduce drafts and make the home more comfortable. It also makes the furnace more efficient by decreasing thermal loss and the entry of cold outside air.

• Detecting drafts can be done with tissue attached to a coat hanger or with a candle. Move either of these in proximity to the frames of windows or doors to detect air movements through any gaps.
• Caulk can be applied around the exterior frames to close these gaps.
• Weatherstripping can be applied between a window or door and its frame to fill larger gaps.

Reverse Ceiling Fan Direction

Ceiling fans are commonly used during the summer. They don’t make the air cooler, but the moving air FEELS cooler than stationary air. Ceiling fans can increase the comfort of a home during the winter as well; here is how to make this work.

• During the summer, ceiling fans should turn counterclockwise; this pulls cool air from near the floor up to the ceiling and pushes it toward the walls.
• However, the direction needs to be changed for wintertime use. Find the switch in the center of the fan to change the direction to clockwise.
• Clockwise rotation pushes the warm air near the ceiling down and out toward the walls.

Mixing the warm air increases comfort and reduces the call for more heat.

Adjust the Thermostat

The thermostat is the ON/OFF switch for the heating system and most current thermostats are programmable. This can work to customize comfort and save energy at the same time.

• Suddenly changing the temperature does not produce the desired results; settle on a desired temperature and leave it.
• Many people prefer to sleep in a cooler room; scheduling a reduction in temperature overnight can provide this extra comfort. Schedule a return to normal temperature about 30 minutes before the alarm clock rings as a buffer.
• If the entire household is gone during the daytime hours, a second reduction in temperature can also be scheduled automatically. A 30-minute buffer before the first family member returns will create the desired comfort.

Reducing the temperature by 8 degrees for 8 hours per day will reduce heating costs by 10% without reducing the comfort level for any family member.

Stay Safe and Smart: Essential Electrical Safety Tips for Kids

Do you remember rubbing a balloon on your hair and using static electricity to shock someone? Friction causes your hair to collect electrons from the balloon for a while, then release them onto your friend’s nose.

Large clouds use the same principle to create lightning. Since cumulonimbus clouds can weigh over 2 billion pounds, the amount of static electricity in lightning is immense—the average lightning strike releases 300 million volts.

Scientists and engineers use motion—hydro, wind, and steam-powered turbines—to pull electrons in large quantities to produce steady streams of electrons or electric current. Electric current is used to power our homes, businesses, industries, and communities.

So, we pull electrons for our use, and they keep moving, seeking to be released somewhere that needs lots of electrons. Wiring keeps the electrons contained but electrons will use any chance available to seek a large mass needing plenty of electrons. The largest mass available is the earth itself, so we say electricity is seeking “ground.”

If a substance refuses to allow electrons to move, it is called an insulator. If a substance allows electrons to move, it is called a conductor. If a conductor causes the electrons to slow down, this is called resistance and resistance causes intense heat.

We use resistance in toasters, hair dryers, and ovens. However, if current tries to pass through a resistant conductor that is not designed to carry current, the intense heat can cause a fire.

The human body uses electricity constantly, but the currents are extremely low. How low? Electrical signals are measured in millivolts—a strong signal is approximately 30 millivolts or .03 volts. Contact with a current of 120 or 240 volts is extremely disruptive to organs that produce these millivolts (the heart or brain are good examples). The surrounding tissue is a resistant conductor, so a high current is very destructive to cells.

Use these principles to develop electrical safety standards around your home.

1. Children are curious and do not know of the dangers of electricity. It is up to parents to take measures (often called childproofing) to protect young family members. Plastic plugs and tamper-resistant outlets are cheap corrective tools when applied before a disaster. Develop electrical safety protocols with the most vulnerable in mind.
2. Appliances often put resistance to work to complete everyday tasks. That means both heat and current are very close to individuals who use electrical devices. Since they come into contact with both human bodies and combustible materials, be sure to repair or discard broken devices and extension cords.
3. Trying to force too much current through wires, outlets, or extension cords changes them from conductors to resistant conductors. The resulting heat will create fire hazards and sometimes the evidence of damage is hidden behind the wall. Have an electrician add sufficient circuits to meet household needs and avoid the dangers of overloading/overheating devices.
4. Water is an EXCELLENT conductor of electricity, so we say “Water and electricity should not mix.” Building codes require that anywhere that electricity comes within 6’ of a water source—in kitchens, bathrooms, laundry rooms, or near pools—ground fault circuit interrupter outlets and switches be installed. GFCI devices trip at the outlet or switch when a ground fault happens, many times faster than it takes for the breaker to trip at the electrical panel. Outlets, switches, and cords in outdoor settings are especially susceptible.
5. Overhead cables carry a much higher current than indoor wiring. Remember, all that current is seeking to do is reach the ground. Be extremely careful with ladders, poles, or body parts to avoid becoming the conductor. Avoid contact with trees that have limbs that touch power lines, especially whenever it is raining, or the wind is blowing.Downed power lines are extremely dangerous since they carry very high voltage. Coming into contact is usually deadly, but contact is not the only danger. Often, the ground is wet, making the surrounding area a pool of conductivity.

Holiday Electrical Safety Guide for Homeowners

The holidays are fast approaching, and you know what that means. Annual outdoor decoration contests will soon begin in neighborhoods that rival our favorite Christmas comedies. Many homeowners collect holiday decorations year-round, with multi-color lights, inflatables, and animatronics becoming very popular. In the next two months, decorators have three prime holidays for embellishing their lawns and homes. If you are all about decorating, have fun! But don’t forget these decorating Holiday Electrical Safety Do’s and Don’t tips to keep your holidays bright and safe.

Don’t overload circuits. Residential circuits are designed to handle about 1800 watts; loading a circuit beyond this risks tripping the breaker. Remember that your outdoor outlet is often a part of a circuit with indoor outlets as well; add the wattage for anything plugged in indoors as well. Add up the wattage for the decorations you plan to use and do not load past 1500 watts just to be sure.

Do consider adding a circuit. If you desire to use plenty of outdoor decorations, ask your electrician about adding another circuit (or circuits) to handle outdoor outlets.

Do shop for LED decorations. LED lights use a fraction of the energy of traditional lights with the same or better brightness. Make sure that all decorations are rated for outdoor use.

Don’t bury extension cords. Be creative when it comes to hiding wires and cords, but they should not be buried. The ground is holding moisture, even during dry spells; this moisture is keeping the grass and shrubs alive. Any flaw in the cord and every connection will expose the current to water, creating a short and potential shock hazard.

Do elevate connections. Lift cord joints and splitters to keep them above standing water during a rainstorm. A rock or board will raise the vulnerable connection out of danger. (Be creative! Take it as a challenge.)

Do use a timer. Decorations are fun as long as people see them, but unnecessary while everyone is sleeping. Matter of fact, they can be annoying while people are trying to sleep. Purchase an outdoor-rated timer to bring everything to life as dusk approaches and turn it off at a reasonable time overnight. This also reduces the wear and extends the useful life of decorations.

Don’t turn off some lights. The Federal Flag Code approves displaying the American flag 24 hours per day, but only if the flag is lit overnight. If you are patriotic and a creative decorator, make sure to keep the flag lit all night long.

Is an EV Charger Installation a DIY Project?

With any new car purchase, significant sales attention is placed on the comfort and amenities of a particular model. With internal combustion engine vehicles, fueling options abound; however, an important side note to purchasing an electric vehicle (EV) is an EV charger installation at your home. If you have not considered this challenge, here are some basic observations for you to consider.

Three Levels of EV Charger Installation

There are three charging options for EVs—Levels 1, 2, and 3. Chances are, you will probably have opportunities to use all three levels, but one option will be your everyday choice.

• Level 1 charging is a basic outlet connection—an extension cord for your car. The good news is that any outlet in the US can be used to charge your vehicle. The bad news is that it is very slow (compared to other charging options). Level 1 charging from 0% to 100% can take 24 hours.
• Level 2 charging is a 220v connection, similar to your dryer or range plug. The good news is it is 5 times faster than Level 1 charging, and 0% to 100% charging can happen overnight. The bad news is it requires professional installation in a secure location.
• Level 3 charging is a public, commercial option. The good news is Level 3 charging is very quick—0% to 100% can be achieved in about 30 minutes or so. The bad news is that it is the most expensive of the three options.

Most EV owners will adapt and use more than one—probably all three EV charger installation options—in the useful years of an EV.

Two Home EV Charger Installation Options

Levels 1 and 2 are optionally accomplished at home, but there are differences and similarities between the options.

• The cost of charging for either Level is the same. The cost can be determined when you know the cost per kilowatt hour charged by your utility company. The kilowatts used will be the same; Level 1 just takes longer than Level 2. A general figure for charging cost would be in the $10 to $15 range.
• The average driver in the US drives about 40 miles per day or about 280 miles per week. How close do you come to being an average driver? This information can help you determine the charging level that suits your driving needs. Do you have a whole day of the week that you will not drive to allow for a day of charging?
• EV manufacturers recommend charging patterns that prolong battery life. That includes avoiding extremes for normal charging—do not let your EV discharge to 0% or fully charge the EV to 100%. (While commercial charging may be a convenient or necessary option from time to time, it is hard on battery life and should not be the go-to method of charging.)

Charging options are available to meet the needs of most US drivers. Before an EV purchase, a car buyer should predetermine the charging plan that suits normal driving patterns.

EV Charger Installation Home Options

For most EV owners, that will include both Level 1 and 2 charging stations, and the most obvious location will be in a garage.

• Level 1 charging might be accomplished with no home modifications. However, if this is a long-term solution, it would be best for an electrician to create a dedicated circuit to avoid overloading.
• A Level 2 charging option will require some minor modifications, requiring the services of a professional electrician. The charging station will be wall-mounted, with dedicated 220v wiring behind the garage wall. The station will be a small box with a sufficient charging cable to access the vehicle. Work with the electrician to mount the station in an easily accessible location.

The Importance of Routine Commercial AC Maintenance

For many business organizations, this is prep time for the 2025 budget year. Inevitably, the question of whether HVAC preventative Commercial AC Maintenance needs to be a line item will come up. The budget might be tight, so it might be tempting to forgo maintenance this year—what could happen? Does this sound familiar?

Neglecting Commercial AC Maintenance for one year often ensures the line item will not be added to the budget next year either. The long-term result of neglecting Commercial AC Maintenance can be very harmful to operations and the longevity of the equipment that makes business and commerce possible. The extremes of both hot and cold weather are offset by the HVAC system if it works properly. Commercial HVAC systems are much different than those that service single-family residences:

• Commercial HVAC systems often condition much larger spaces.
• The occupancy for commercial spaces is generally much larger.
• The entry/exit rate is usually much higher, requiring more frequent heating and cooling cycles.
• Some commercial spaces generate significantly more heat, such as commercial kitchens.

An interruption in the HVAC system function will often close a business; at the very least, it will severely reduce foot traffic and productivity.  A lot is riding on any commercial HVAC system. Maintaining this essential system is extremely important.

It Affects Indoor Air Quality

Commercial spaces are occupied by your staff for 40+ hours per week and clients, customers, or guests that you invite for business reasons. This implies that you are taking steps to keep the standards of indoor air quality (IAQ) high enough to make the workspace safe and healthy. Neglecting maintenance can lead to poor IAQ, triggering asthma, allergies, or other breathing problems.

How Commercial AC Maintenance Affects the Energy Bill

Heating and air conditioning are responsible for between 35% and 50% of the total commercial energy bill. The accounting department prefers it when the HVAC portion of the energy bill is closer to 35% than 50%. No other department is willing to cut its budget to pay for the additional energy cost, so the cost of routine maintenance might be much more cost-effective than at first glance.

Maintenance Basics

What is entailed in maintaining HVAC equipment? It really depends upon the size of the facility and the type of equipment in use. It will look something like this:

Routine Maintenance. Every HVAC system should be inspected and cleaned annually. Technicians will complete visual inspections and test various components for stress or loss of function. This will certainly include checking the refrigerant level and checking electrical controls and sensors. This might require accessing air handler closets and rooftop units to ensure the entire system is performing within design parameters.

Seasonal Preparation. A semi-annual visit might be needed for facilities with larger systems or in locations with extreme weather changes. For large systems, the equipment that cools is different from the equipment that heats the same area. There will be some equipment doing double duty shared by both heating and cooling functions, but all the more reason to check on the performance twice.

Air Filter Changes. If this vital maintenance task is not handled in-house, it needs to be completed by a technician quarterly. The air filter collects pollutants during every heating or cooling cycle, but the airborne particles soon cover the filter and reduce the airflow through the air handler. This causes the equipment to work harder, use more energy, and weaken vital equipment due to stress. It also reduces the efficiency of the filter to adequately collect the dust and pollen floating around the facility.

What Homeowners Need to Know About Generator Transfer Switch Installation

Years ago, a backup generator might have been considered a luxury for the average South Texas homeowner. However, weather events in the last few years have rendered what was once a luxury more of a necessity. If you are reading this article, you might also be considering a Generator Transfer Switch Installation to make your home safer and more comfortable during power outages.

Generators use fuel—natural gas, propane, and diesel are common energy sources—to produce energy for home use. But, since your home is connected to the power grid, re-introducing power to the home can reenergize the power grid. This is extremely dangerous for linesmen working to restore power, since they will not expect the lines to be energized. Sending power to neighboring homes can also create dangers for unsuspecting families.

The safety solution for generator use is a device called a Generator Transfer Switch. Generator Transfer Switches automatically disconnect the home from the power grid whenever the generator begins to operate. When power is restored, the Generator Transfer Switch disconnects the generator from the home’s electrical system and re-establishes connection to the power grid. Hiring an electrician for a Generator Transfer Switch Installation is an essential part of using your generator when the power goes out.

Types of Generators

There are two basic types of generators, although variations are offered for both types:

• Whole house generators are permanent structures, installed at least 20’ from the home to prevent the exhaust from the generator from entering the home. They are powered by the natural gas or propane supply used by the home. These generators are usually powerful enough to empower all the circuits in a home’s wiring network and cables connect the generator directly to the electrical service panel. The generator begins operating seconds after power is interrupted.
• Portable generators are mobile units, stored in readiness and put into operation whenever the need arises. An ample supply of fuel must also be stored. These generators must also be used far enough away from the home to keep exhaust from entering the home. Portable generators may or may not be powerful enough to empower the home’s entire circuit network. Therefore, the homeowner determines the desired circuits to be empowered and trips the breakers for circuits not in use.

The portable generator often cannot supply sufficient power to 220v appliances, such as ovens, dryers, and HVAC systems. Portable generators must be readied, connected to the electrical service panel, and started manually during a power outage.

Generator Transfer Switch Installation Types

• Whole house generators require an automatic transfer switch This switch is installed between the home’s connection to the power grid and the electrical service panel. When an outage occurs, the switch breaks the connection to the grid and opens the connection to the generator. The generator starts within seconds of the power outage, resulting in a short flicker of power. When power is restored to the grid, the switch shuts off the generator, breaks the connection with the generator, and reopens the connection to the power grid.
• Portable generators require a transfer switch as well, but a manual transfer switch is installed. The manual transfer switch performs the same safety function as the automatic switch, closing the connection with the power grid and opening the connection to the generator. However, since there is nothing automatic about portable generators, they need a manual transfer of power. When power is restored, the homeowner manually flips the switch, disconnecting the generator and re-connecting the power grid. The portable generator is turned off and disconnected from the service panel.

Air Pro Electric is available for the installation of whole-house generators, and both automatic and manual Generator Transfer Switch Installation.

Electrical Repairs That Could Lead to Dangerous Situations

Each year, more and more common tasks are accomplished by household electronic appliances and daily life is not the same without these conveniences. The increase in electrical use can create one problem, but these electrical repairs may manifest itself in several symptoms.

Electricity flows in a circuit through a network of wires, but the network is very organized. The organization happens because wires of the network cannot carry an unlimited amount of electrical power. The network is divided into smaller loops called circuits, to evenly distribute the flow of electricity throughout the house.

At the beginning of each circuit is a switch, a circuit breaker, which is designed to close (or trip) if the circuit exceeds the designed electrical flow. Several of the most common electrical repairs that elicit a call for an electrician are caused by overloaded circuits.  Some of those problematic electrical repairs include:

1. Repeated Circuit Breaker Trips. Circuit breakers are designed to break the flow of electricity when too much electricity flows through the breakers. The cause of the increase in flow might vary—a lightning strike, a short or fault, or a malfunctioning breaker. But when too many devices call for more power than the circuit is designed to handle, the circuit will trip.
2. Warm (Hot) Outlets and Switches. Switches and outlets attached to an overloaded circuit can be hot to the touch. The heat might be sufficient to distort or discolor the shape of the cover plate, although this can also be caused by a short or fault. An overloaded circuit may also cause a burning smell or the odor of melting plastic. Warm outlets and switches are clear indications of a serious problem since wiring inside the walls can get hot enough to start a fire. Do not ignore this problem.
3. Hot Extension Cords or Appliances. The heat of an overloaded circuit may also be detected when an extension cord or appliance is hot to the touch. Remember that extension cords should be a temporary solution, not a permanent fixture. Appliances should not give off abnormally high heat.
4. An Outlet or Switch Ceases to Function. An overloaded switch or outlet may cease to function. While this might be inconvenient, consider this a good safety factor.
5. Flickering Lights. Often a light will flicker just before it fails, but if the lights flicker—brighten, then dim in quick sequence—it may indicate an overloaded circuit. The flickering might be intermittent, or it might happen whenever a particular appliance is switched on. If the kitchen lights and the oven are on the same circuit, the lights may flicker each time the oven element heats up.
6. Loud Buzzing. Some devices are designed to buzz. Devices that are not designed to buzz should not buzz. Electrical panels, switches, and lighting should not buzz.

If you experience any of these electrical repair problems associated with overloading circuits, take the following steps:

• Identify the boundaries of the problem circuit
• If lights flicker every time a particular device is turned on, explore and identify the problem
• Move some of the devices to other circuits if possible
• If an appliance is hot and is not supposed to be hot, stop using it
• If an outlet or switch is hot, stop using it (if possible)
• Call a licensed electrician to explore solutions that will reduce the risk of injury or fire

AC Maintenance North Houston Experts To Stay Cool This Summer

The heat and humidity this summer are as intense as ever, emphasizing the importance of air conditioning to our daily schedule. Since the economy is heating up as well, making air conditioning as energy-efficient as possible is doubly important. Here are four simple principles to reduce the cost of air conditioning each summer.

Heat Transfer

The main air conditioning principle is heat transfer. When an ice cube is set out on the counter, heat is attracted to the ice, and it melts. This attraction is very similar to the way a magnet attracts iron. Within the air conditioner components, the refrigerant becomes very cold within the network of tubes, and hot, humid air from inside the house is passed over the tubes. The heat moves toward the cold and is transported outside.

• The heat is removed from the home through the evaporator coil in the central air cabinet.
• The heat is released into the outdoor environment in the condenser unit outdoors.

The enemies of heat transfer are dirt and contaminants. As they collect on the network of tubes, both indoors and outdoors, they block the transfer of heat, making it more difficult to make the transfer. Keeping them both clean is essential to the air conditioning process.

Air Movement

Heat transfer requires a lot of air movement at every stage. During a cooling cycle:

• All the air within a house must move through the evaporator chamber. This ensures the heat moves from the home to the evaporator coil. The humidity also condenses on the coil and is removed from the home.
• This air moves very rapidly, the entire volume of the home moving repeatedly with each cycle. This ensures the air is thoroughly mixed, while the heat and humidity are removed.
• The refrigerant that collects the heat gets very hot and it MUST be cooled very quickly since it will recycle within the cooling cycle. A huge fan in the center of the condenser draws air through the network of coils.

It is vitally important to keep these components clean and free of contaminants. They tend to become sticky and attract other contaminants. The buildup quickly restricts heat transfer. The most obvious example of this is the air filter; when sufficient dust collects on the filter it restricts airflow, forcing everything to work harder.

Thermal Barriers

While the air conditioner is transferring heat, the rest of the building envelope is also transferring heat.

• The attic is hot, and the heat is seeking entrance into conditioned space.
• The sun is shining directly on the walls, and the heat is seeking entrance.
• The windows and doors also allow heat to readily enter the home.

It seems the whole building is working against the air conditioning process! For this reason, it is important to create the best thermal barrier available. That means attic and wall insulation that prevents as much heat transfer as possible. Glass transfers heat very readily. Double-pane windows capture a pocket of air between the panes and slow the transfer a bit. Make sure your home is caulked and weather-stripped properly to reduce the amount of heat entering the home through small gaps in the building envelope.

AC Maintenance Required

The whole air conditioning system is controlled by sensors and sensitive control electronics. The refrigerant must be kept within a very narrow range of pressure. Various parts must be cleaned regularly. Your AC technician has the training and experience to keep your system running efficiently year after year.

Homeowners have so many responsibilities and interests that they cannot become experts in the care and maintenance of all the home’s building system. However, it is in the interest of all of us to be familiar with major problems that commonly develop. Here is a list of some of the most common electrical repairs with residential electrical systems.

1 Arc faults

We observe the power and utility of arching electricity in modern devices, such as Tesla coils, plasma balls, and stun guns. Electricity arcs when it moves into the space between two conductors. In residential settings, this can happen when wiring is installed incorrectly or damaged. It often happens during the fraction of a second when the plug of a device nears a receptacle.

The danger of an arc fault is the electricity is being diverted from its intended course. It can result in a shock or electrocution should it encounter living things. It can cause a fire if it encounters any type of fuel. An arc fault might be visible. It often can be heard. Arc faults often chemically change the air and give off the smell of ozone. They are dangerous, so shut off the power to the problem area and call an AirPro electrician for electrical repairs.

2 Ground faults

Electricity should flow through a closed system called a circuit. Switches are used to break the circuit to disrupt the flow and shut off the power to a device. When electricity moves outside of this designated circuit, it moves to the earth through the closest route possible. We call this a ground fault. When electricity moves, it chooses the easiest, least-resistant path. That might be a fuel source, resulting in a fire. That might be through a living source, with disastrous consequences. Ground faults give fewer indications. They are dangerous because they are often undetectable until it is too late.

Circuit breakers are designed to recognize a change in the flow of electricity. If more or less electricity flows through a circuit, the breaker trips. There might be another reason for a circuit breaker to trip. If you reset the breaker and it trips again immediately, call an AirPro electrician for electrical repairs.

3 Water and electricity

Whenever electricity comes into contact with water, it causes an immediate ground fault. The danger is so severe that building codes require Ground Fault Circuit Interrupter (GFCI) switches and outlets installed within 6 feet of a water source—faucets, tubs/showers, pools, etc. What does a GFCI device do? Normally, the ground fault happens, and the circuit breaker recognizes the change in resistance and trips. This might take a second or longer, but GFCI devices are designed to recognize resistance changes as small as 4 to 5 milliamps and respond in 1/10^th of a second. These are truly life-saving devices.

4 Overloading/overheating

The wiring and circuit breakers in a residential system are designed to carry a limited amount of power. This limitation is for the protection of persons and property, but it is also designed for the devices we use. Calling for more power than the circuit is designed for will lead to damage to devices and heat damage to wiring and circuitry. The faceplates for overheated circuits may melt or discolor. They will often feel hot to the touch.

Calling for too much power will trip the circuit breaker. If turning on one too many devices results in a tripped breaker, request an added circuit from your AirPro electrician for electrical repairs.

5 Power surges

Speaking of too much power! The power grid is designed, just like a residential system, to deliver a certain amount of power and redundant regulator devices are designed all along the system. However, certain anomalies happen that result in a sudden increase or surge of power. An accident involving a power pole, a rodent interrupting the grid, or a lightning strike are all examples of surge sources.

Power surges are completely out of the control of homeowners, but if your home requires further protection, ask your electrician about a whole-house surge protector.

Ultimate Spring Checklist for HVAC Maintenance

We look forward to the coming Spring each year. Warm weather and plenty of sunshine make ball games, cookouts, and evenings on the deck, listening to songbirds and children, very pleasant. It is also an occasion to switch the thermostat from HEAT to COOL.

How long has it been since your air conditioner ran? Perhaps four or five months of inactivity should prompt you to give it a little pre-season care!

Do-it-yourself HVAC Maintenance Tasks

• Replace your air filter. If you change your filter on schedule (about every three months), you will know the condition of your filter. The change to the cooling season is a good prompt for filter changes.

Air conditioners require great quantities of air to move across the refrigerant coils. Since dust and dander collect on the filter, it eventually clogs the filter, so make sure the filter is clean at the beginning of the cooling season.

• Clean the condenser unit. The outdoor condenser unit has been collecting leaves, dust, and blowing debris, so make sure to clean it thoroughly. Remove the covers and use a garden hose to rinse away the accumulated dust and lawn clippings from the fall. The large fan on the inside pulls a lot of air through the network of coils to transfer heat; the dust and debris interfere with the heat transfer.
• Clean the evaporator unit. Flip the breaker for the air conditioner and take the cover off the evaporator chamber. Spray a 50/50 solution of vinegar and water onto the evaporator coils. This loosens any dust particles from the coil for the same reason as the condenser coils—heat transfer.

The drain pan is situated under the coil. The moisture that is removed from the humid air drips into the drain pan. Clean away any debris from the drain pan; this can get caught in the drain line and result in an overflow. Pour the remaining solution into the pan. This prevents algae growth in the drain pan and line.

Professional Tasks

Some tasks need to be completed by a professional technician. Those tasks include:

• Checking the Freon. The air conditioner cools by compressing refrigerant gas, often called Freon, and then releasing the pressure. Since the whole gas network is a closed system and the gas is under pressure, even a very small hole will allow all the gas to leak away. If the gas pressure is low, the technician will find and fix the leak, then replace the Freon.
• Inspecting the thermostat. The thermostat is the switch for the air conditioner, and it also needs some care. They run on batteries, which need to be changed annually. The technician will use a thermometer to test and calibrate the thermostat setting.

This might be an ideal time to replace an old thermostat with a Smart thermostat. These thermostats are programmable and adaptive, and they have a cellphone app that allows customized comfort selections.

• Test the Electronics. As the air conditioner cycles on and off, electricity slams through the switches and controllers very suddenly. While there are few moving parts, the constant cycling creates wear and tear. As a part of the maintenance visit, the technician will test the electronics for weaknesses.
• Clean the vents. The ductwork for the air conditioning system will collect airborne particles that blow past the air filter. Over the years, the dust can build up and contribute to poor indoor air quality. Technicians can disturb the collected dust and vacuum it away; make sure to clean both the cold air returns and the supply vents. Vents should be cleaned every three to five years.

What You Need to Know About Circuit Breaker Repair 

Should you visit the electrical aisle at your local home improvement box store, the varieties of circuit breakers might be surprising. If you need circuit breaker repair or you are replacing a breaker for your home, the decision might be overwhelming. Why all the choices, and what do they mean?

Circuit Breaker Repair and Knowledge Basics

Before electricity enters a home, the current is regulated by a utility transformer to ensure the flow of electricity is usable by appliances and devices.

• Electric power is measured in voltage. A total of 240 volts comes into the electric service panel. Circuit breakers carry some of this power unchanged to large appliances such as the dryer or kitchen stove, while other breakers split the power to some circuits into 120-volt currents such as lights and media devices. Circuit breakers carrying 240 volts are called double pole breakers, and breakers carrying 120 volts are called single pole breakers.
• Electric current is measured in amps. Circuit breakers also restrict the amps a circuit can carry, protecting the devices from a current overload. The common amperages for single pole breakers are 15 and 20 amps. Double pole breakers often carry 30 or 40 amps.

Some circuits may require specialty breakers, but these are the most common varieties.

Breaker Purpose

Circuit breakers are designed to regulate the flow of power and current. When electricity exceeds the designated power or current, the breaker is designed to trip, breaking the circuit. Circuit breakers replace fuses. Fuses accomplish the same function but are designed for one-time use only. Circuit breakers are reusable; a tripped breaker can be reset.

What causes a breaker to trip?

• An overloaded circuit. When too many devices call for electricity, it can exceed the circuit design and cause devices to overheat. In extreme cases, an overheated circuit can cause a fire. When a circuit overloads, the breaker trips, stopping the flow of electricity. Before resetting the breaker, remove some of the devices, or the breaker will trip again.
• A short circuit. Electricity must be contained within a designated path, a circuit. When electricity finds an alternative path to the home’s electrical network, it is called a short circuit. The breaker recognizes the incorrect path and trips. The breaker trips very quickly and for very good reasons. A short circuit will damage devices and can create a fire hazard.
• A ground fault. Electricity must be contained within a designated path, a circuit. When electricity escapes from the circuit, the current does not return to the electric service panel. The breaker is designed to recognize this problem and trips very quickly. Free-flowing electricity will cause shock to anyone encountering the short, and it also poses a fire hazard.
• An arc fault. Electricity must be contained within a designated path, a circuit. When an electrical connection is loose, it will cause a spark and jump to surrounding structures. The breaker recognizes that the current has been diverted and trips. An arc creates intense heat—between 5,000 and 35,000⁰ F- leaving a burn mark or discoloration when it happens in the open. Arc faults can cause burns and shock and create a fire hazard.

Circuit breakers are important safety features in any structure.

GFCI Outlets and Switches

Water is an extremely good conductor of electricity, and electricity seeks the path of least resistance. Whenever water and electrical circuits are in close proximity, building codes require ground fault circuit interrupter (GFCI) switches and outlets. Circuit breakers are fast, but GFCI breakers are more sensitive and much quicker.

• GFCI will break the circuit with only a 4-milliamp current.
• GFCI will break after 1/10^th of a second.
• GFCI will break the circuit at the switch or outlet instead of at the service panel.

Ground fault circuit interrupters are an additional level of safety used in kitchens, bathrooms, laundry rooms, and around pools.

Furnace Maintenance That Every Homeowner Needs to Know About

As the American continent developed and folks settled into the land, homeownership became a reality for more and more people. When you combine homeownership and a sense of independence, it results in a protective, do-it-yourself perspective. Ordinary people learn unusual tasks to take care of their own property.

However, it isn’t easy to consider residential furnace maintenance as a do-it-yourself project, especially a gas-powered furnace. While there remain some tasks that HVAC technicians must accomplish, here are some tasks that homeowners can accomplish.

Supply Line Furnace Maintenance

If the gas supply has been turned off during the summer months, inspect the supply line and valve before turning the gas to the ON position. Follow the gas line to the furnace and locate the valve. With a soft bristle non-metallic brush, clean away any corrosion from the exterior. Ensure the valve turns freely–in an emergency, the gas may need to be shut off quickly.

Furnace Maintenance: Cleaning the Cabinet

At the electrical service panel, close the circuit market Furnace or HVAC. This protects you from electrical shock. Bolts hold a couple of panels in place. Remove the bolts and remove the panels to access the interior. Use the brush attachment on a shop vac and gently vacuum away dust from every surface that can be reached.

Give attention to the fins of the blower motor and the drip pan. During the cooling season, this drip pan collects the humidity the air conditioner removes from indoor air. Vacuum away dust and rust that may lead to a clogged drain line next spring. As you vacuum, be careful not to dislocate wire connections or dislodge components. Reconnect or tighten any poorly connected wires.

If you can view the rear portion of the blower fan, observe the condition of the drive belt. Look for cracks or fraying on the belt. Replacing the belt yourself is not advisable without serious mechanical skill. Make note of its condition and bring it to the attention of the technician during the next service call.

Restore the panels and tighten the bolts.

Furnace Maintenance: Change the Air Filter

Hopefully, you have changed the air filter frequently over the years and are familiar with its location. However, take a closer look and understand why it is placed in that spot. Air returns are scattered around the home and when the heating (or cooling) cycle begins, the entire volume of the home is pulled through this site and the filter. This happens about every 2 minutes of the cycle; if that doesn’t impress you, it should.

Since this extreme volume moves quickly through the filter, it is important to change the filter often—every three months is a starting point. By your observation, you may realize the filter needs to be changed more often. A clogged filter will severely slow the airflow and put increasing stress on the furnace to perform properly.

Other Furnace Maintenance Tasks

Most thermostats are battery-powered, so the batteries will need to be replaced annually. Hopefully, this is a familiar task since batteries should be replaced in smoke and carbon monoxide detectors to keep your home safe.

While you might not be able to reach the majority of your ductwork for cleaning, clean the sections that you can reach. Make sure the registers and returns are uncovered, allowing the free flow of air.

While there are many tasks that an observant homeowner can do, there are some tasks that must be completed by a technician. These include inspecting the ignition source, the burner unit, the heat exchanger, and the exhaust vent. The same attention will be paid to electrical controls and switches to ensure the system functions efficiently.

Deciding Between HVAC replacement or HVAC repair

During the fall, it is not unusual to have temperature swings that require both the air conditioning and heater on the same day. This highlights how dependent we have become on our HVAC system for comfort and health, and it would be terrible to do without it for several days or weeks.

Whenever a repair is necessary, it might elicit some concern about eventual replacement. How will you know when it is time to replace rather than repair the system? Here are the top HVAC replacement vs HVAC Repair indicators that will help you make a wise decision when that time comes.

Know the Age of Your System

Major air conditioner components have an average lifespan of 15 years, while furnace components will last a little longer, about 20 years. If you know when your system was installed, it will give you an idea of when the system should be replaced. While it is possible to replace the air conditioner without changing the furnace, it is most common to replace both at once.

Technological Advances

In recent years, researchers have produced advanced refrigerant gases—the key to air conditioning and heat pump heating. Older gases have been determined to be hazardous to the environment and will no longer be manufactured.

Therefore, if your aging system leaks an outdated refrigerant gas, replacement may be quite expensive or impossible. If you need to determine the refrigerant gas of your system, research the make and model number online.

If your system is ten years old or older, technological advances in new systems will significantly reduce energy consumption and therefore reduce the cost of heating/cooling.

Incentives

Government agencies and local utilities offer financial incentives for replacing aging systems. Government agencies are encouraging lower carbon emissions. Local utilities can reduce their cost by producing less energy. One HVAC system with improved efficiency does not make a difference, but encouraging many improved systems will make a difference.

These incentives will not cover the entire cost of a system replacement, but they will definitely help most family budgets.

HVAC Replacement or HVAC Repair Costs

Complex repair cost calculators are available but are not necessary. A few indicators will help you determine that the required repair is too expensive.

• First, determine the replacement cost for your current system, including installation cost. A ballpark figure is sufficient.
• Second, record the timing and cost of various repairs over time. Do not include costs for maintenance or cleaning calls since these should be scheduled for both existing and new systems.
• Third, watch for components that need to be replaced every year or so, or one repair that leads to another, more expensive repair.
• Finally, as the system ages, anticipate a major, expensive repair that rivals the cost of replacement.

These indicators should prepare a homeowner to determine when a repair is too expensive.

Family Comfort

An aging system may also lose efficiency to the point where your family is uncomfortable—too hot in the summer or too cool in the winter—may be the deciding factor in your decision. An aging system may also negatively impact the indoor air quality in a home, making the space uncomfortably humid, dry, or have a musty smell.

These factors will give homeowners adequate information for deciding to forgo the repair in favor of a system replacement.

Commercial Air Conditioning What You Need To Know About Costs

Sometimes the internet can be so helpful and sometimes it can be a royal pain. It is excellent for purchasing commodity items with set prices and known shipping costs. It is not very helpful when you research large ticket items or services; there are so many variables that affect the price, and no one will make an estimate on a project “sight unseen.”

If you are planning Commercial Air Conditioning replacement for your building, you need to budget figures for planning purposes that come close to reality. Good luck wading through complicated square footage calculation x a dollar amount that ranges from $3/sf to $35/SF. That much variation is not helpful at all!

We are going to give you two simple calculations and a simple list of variables. We figure that if you manage a commercial property, you will be able to take limited information, complete some research, and make a projection for the budget. So, let’s dive in.

Two Simple Commercial Air Conditioning Calculations

• Square footage of the building x 25 = BTUs needed for air conditioning. Twenty-five represents the average air temperature change needed. If the outdoor temp is 100⁰ F, AC will need to bring the indoor air temperature to 75⁰ Example: 20,000 SF x 25 = 410,000 BTUs.
• BTUs / 12,000 = AC tons Air conditioners are sold in tons. Example: 410,000 BTUs / 12,000 = 34.2 tons

At least you have a base model to determine to price. But you are not finished quite yet.

Simple Variable

Tonnage is a starting point, but there are some variables that will affect the price. Variables may have a positive or a negative impact on your installation cost and operation cost.

Building Type

Several things about your building will impact the cost of installing new AC. Are you trying to cool a single-story strip center or a five-story office building, needing a crane to lift heavy equipment? Are you cooling a gym, with 12-foot ceilings, filled with people and machines generating a lot of heat, or an office farm with 8-foot ceilings with people doing rather sedentary work? The more complicated the installation, the higher the cost.

Types of Commercial Air Conditioning Systems

Various building types and business applications will require different types of AC systems. Here is a list of common AC applications.

• Package Units closely resemble residential HVAC systems (heating and cooling will use common components, and refrigerant gas passes between an outdoor compressor and an indoor blower. (Adding heating capacity to your AC system will impact your component cost.)
• Mini-split ductless systems are used to cool small zones, such as hotel rooms or apartments.
• Variable refrigerant systems cool large spaces and may use air, water, and/or refrigerant gas.

This is a simple list—there are many more system types. Since you know your building well, this gives you a better idea of the major type of system you will need.

Added Commercial Air Conditioning Features

So far, you have been looking at “base models,” but your long-term goals might require some feature upgrades. While doing research, watch for the cost of a few upgrades to help with budgeting.

• SEER rating. Air conditioner efficiency is rated in SEERs or seasonal energy efficiency ratings, the higher the SEER number, the more efficient the system. If your building requirements or operational requirements demand energy efficiency, watch for the SEER or SEER 2 rating that takes effect in January of 2023. Efficiency comes with a higher capital expense but is recovered quickly with lower utility bills.
• Air quality. Ultra-violet (UV) light damages the cell walls of living organisms—UV light causes sunburns. Installing UV light in the ductwork neutralizes (kills) microorganisms as they move through the system. Mold and mildew spores, pollen, bacteria, and viruses are reduced to dust and removed by air filters. The cost is low, and the benefit is high if you have room in the budget.
• Automated controls. Reducing access to the thermostat(s) is a good idea. Scheduling temperature changes for energy savings is wise. Wi-Fi access to building controls is convenient. Look at some of these system control features.

A few other variables will come out in your research, such as brand differentials and local labor costs, but normal research will uncover these indicators. This article did not declare a cost for your system; that was not the goal. We hope this gives you enough information to help you research the cost of replacing your Commercial Air Conditioning for budgetary purposes and to give you a starting point to begin shopping for the best contractor to install your new system.

HVAC Duct Cleaning During Your New AC Installation

After many years of faithful service, the time has come to replace your entire heating, ventilation, and air conditioning (HVAC) system. The contractor has been selected, the equipment has been ordered, and the installation has been scheduled. Before the installation, you have a little time to contemplate the installation process and prepare your home.

Here are some tips to consider in preparation:

This is an excellent time to clean your HVAC ductwork. Ducts transport conditioned air throughout your home and this air carry many airborne particles invisible to the naked eye. You are constantly removing these particles when you dust and vacuum your home. These same particles are accumulating in your ducts. Since the new components of your HVAC system will be shiny and clean, clean the old portion of the system in preparation.

Preparing for HVAC Duct Cleaning

• Declutter the areas around each supply vent (floor vents in most homes) and return registers (larger wall vents close to the ceiling). The duct cleaning contractor will need access to all of the openings.
• The dust will be vacuumed away from vent openings, but if possible cover furniture near the vents to catch any residual dust.
• Protect children and pets by keeping them well clear of workspaces. The process will be exciting—with several workers moving around, and noisy.

The HVAC Duct Cleaning Process

• Our HVAC duct cleaning team will make a visual inspection of various duct locations before cleaning the ducts. Inspections can uncover gaps in the sheet metal connections that allows air to escape into the attic, basement, or walls. It might also reveal the presence of pests or a mold infestation. The inspection might include video equipment or mirrors to make thorough inspections.
• Before the cleaning begins, the vents and registers will be sealed to prevent dust and debris from entering the home. After the vents are sealed, negative pressure (vacuum) is applied to the entire duct system. Flexible brushes with spinning heads are attached to a vacuum cleaner hose. The brushes dislodge dust and debris, while the vacuum removes them from your home. Once the ducts are completely clean the seals will be removed from the vent openings. The HVAC Duct Cleaning process takes approximately 4 hours.
• When the HVAC Duct Cleaning process is finished, the team lead might suggest a high-quality filter and remind you that air filters should be replaced at least every three months.

Preparing for HVAC Installation

• Replacing your HVAC system will be just as exciting and involve a team moving around the home. Protect your children and pets by keeping them clear of workspaces.
• On installation day, the team will arrive as scheduled; if something delays their arrival, the team lead will communicate with you about the alternative schedule.
• The team will complete a pre-installation inspection, locate existing components, observe obstacles for the moving equipment, and clear paths as needed, and foot-traffic covers and tarps as needed to protect your home.

The Installation Process

• As a precaution, the power and gas lines (as needed) will be disconnected and will remain disconnected until the installation is complete. (Avoid very hot or very cold days if possible.)
• The heat pump system uses refrigerant gas for both heating and cooling. Containing this gas is an environmental necessity, so the team will carefully remove the gas from the system lines.
• If electrical upgrades are needed for your new system, they will need to be made prior to installation. An electrical sub-contractor will make the needed upgrades.
• The old equipment will be carefully uninstalled and removed from the house. Keep in mind, HVAC components might be located in the basement/crawlspace, the attic, or a mechanical closet inside the home. New components will usually be installed in the same space as the old units.
• The condenser unit, the outdoor portion of your system, will be replaced as well. It will need to be supported on a solid footing and local regulations may require that it be elevated. The team will ensure a 2-foot clearance on every side of the condenser to accommodate great airflow.
• New connections, tubing, and drain lines might need to be installed to match the new system. Everything will be completed according to the manufacturer’s specifications. Electrical connections and refrigerant gas/natural gas lines will be installed and tested.
• The new refrigerant gas lines will be vacuum evacuated and charged with refrigerant gas. This technology changes frequently; if the gas from your old system is useful, it will be reinstalled.
• Often, a new thermostat will also be installed with the new system.

Post Installation Expectations

• After all of the connections have been tested, the power and gas will be reconnected and the system tested. Both heating and cooling functions will be tested.
• The HVAC duct cleaning team lead will inspect the system with you, the homeowner, making you familiar with the component locations and giving instructions concerning the system’s function. Thermostat settings and scheduling will be demonstrated. There will be ample time for discussion and questions, so make sure you understand the function of the system.
• The HVAC duct cleaning team will load up the old equipment, tools, and floor protection. The team lead will make sure to leave a number in case of further questions or problems.
