Dispelling Myths About Air Conditioning
While the cost of heating is substantially higher than the cost of air conditioning (AC), the period of time that we use our Air Conditioning in Southeast Texas is significantly longer than the time that we use our heating. Often, events totally unrelated to AC function happen that are associated with AC function. When these “myths” are propagated, they can cost you money, so let’s consider whether these events are truth or myth. To celebrate National Cut Your Energy Cost Day on January 10th, we wanted to provide facts about how to save energy and money, without losing the goal of making comfort affordable.
Myth #1 I can cool my house quicker by changing the temperature setting quickly.
The Fact: your AC functions at a set rate and lowering the thermostat setting will take time—approximately 30 minutes—to lower the temperature significantly. A better option is to install a programmable thermostat and schedule temperature changes to match your timetable.
Myth #2 I can cool my home more efficiently with a bigger Air Conditioning unit.
The Fact: the HVAC system in your home was customized for your home, taking many factors into consideration, including the number of doors and windows, and the type of insulation. An oversized AC unit will cool very quickly, but that may also cause it to cycle on and off very quickly. This shortens the life of the unit and uses more, not less, energy.
Myth #3 I can cool my home more efficiently with a smaller Air Conditioning unit.
The Fact: the HVAC system in your home was customized for your home, taking many factors into consideration, including square footage and ceiling height. An undersized AC unit will work harder trying to keep you comfortable, cycling longer than necessary. This shortens the life of the unit and uses more, not less, energy.
Myth #4 I can save energy by turning the Air Conditioning off when no one is home.
The Fact: when you cool the air, you also cool the contents of the house. If you stop cooling during the heat of the day, the contents heat up along with the air. The AC must work very hard to make the home comfortable again. Remember the story of the tortoise and the hare—slow and steady wins the race.
Myth #5 Air conditioning can lead to summer colds.
The Fact: the last two years have made this myth most obvious: colds and flu are the results of exposure to germs—viruses and bacteria, not air temperature. Frequent summer respiratory inflammation might be symptoms of allergies or asthmatic conditions.
Myth #6 If my air filter only needs to be replaced once or twice per year.
The Fact: your air filter is collecting airborne particles with every cycle. The dust, allergens, and dirt accumulate and will restrict airflow. A dirty air filter will make your AC less efficient and cost you money. In addition, the added stress on the blower motor will shorten the lifespan.
Myth #7 I can save money by keeping my old AC system until it quits.
The Fact: while a new AC system can be expensive, it will be necessary eventually. An aging system, beyond 15 to 20 years, might be inefficient and waste energy, costing money. Replacing your AC unit will save enough cash to pay for itself eventually.
Myth #8 Ceiling fans will help keep rooms cooler.
The Fact: ceiling fans do not make a room cooler, but they do make people feel cooler. Fans will not reduce the temperature, but they might allow you to notch the thermostat up a few degrees with the same comfort level. The ceiling fans require less energy than the AC, so they can save money. However, it is important to understand the benefit they do and do not provide.
Myth #9 I can save on AC by closing off the spare bedroom or unused office space.
The Fact: remember myths 3 and 4. The AC unit has been sized to include those rooms, so restricting the airflow by blocking vents will put pressure on the blower motor. In addition, the heat and humidity in this room will be higher and this can promote the deterioration of finishes and growth of mold and mildew.
Myth #10 It is a waste of money to pay for preventative maintenance on my AC.
The Fact: according to Building Efficiency1, a well-maintained HVAC system, cleaned and tested, will last longer and save more energy than a system that is neglected.
