HVAC Emergency: Identifying the Severity of a Furnace Issue

Furnace emergencies are never enjoyable and can be dangerous if they are in the dead of winter. Some HVAC emergency repairs are more threatening than others and require emergency appointments. However, there are minor fixes that you can do yourself.

Furnace systems operate without problems when properly installed and properly maintained by an HVAC certified technician. When a breakdown does occur, it is important to know the difference between an HVAC emergency and a regular heater repair. You can determine the complexity of the HVAC emergency by some simple investigation techniques.

Heating System Emergencies: Know When To Call The Professionals

1) Signs of Electrical Problems

Your home’s electrical system is critical in keeping your home operating at a comfortable level. If you notice that your lights flicker when your heating HVAC system cycles on, you may have an electrical problem with your HVAC unit. Attempting to identify the problem or fixing it yourself can lead to serious injury or death. It is best to leave electrical problems with your HVAC system to a trained technician.

• According to the Electrical Safety Foundation, in 2020:
• Electrical failures or malfunctions were factors in an estimated 43,700 home fires
• These fires caused 430 deaths and 1,620 injuries
• Causing approximately $1.5 billion in property damage

That is why it is important to have a trusted professional to call when you have an HVAC emergency.

2) Loud or Unusual Noises

Loud and unusual noises identify problems. Finding the location of the noises can identify the problem with your system.

What are the different noises coming from your HVAC system?

• Popping or ping sounds are a sign of thermal expansion. This means that your ductwork is expanding and contracting as it heats and cools.
• Rattling sounds indicates that there may be loose panels on your system.
• Screeching and squealing sounds indicate a fan motor that is wearing, damaged, or slipping.
• Grinding sounds are a sign of an HVAC emergency and warrant an immediate call or repair.

Some of these noises do not seem like an emergency. However, if you hear unusual noises coming from your HVAC system components it is best to schedule an appointment to prevent additional damage to your unit.

3) Rapid Cycling of Your HVAC System

If your furnace turns on and off again in a rapid cycle it is a sign of the need for system maintenance. Many times replacing your HVAC system filter will fix this issue. If a new filter doesn’t solve the problem, you may have a more serious situation. There may be an issue with the blower motor and belts and both require the service of a professional.

4) Sulfur or Rotten Egg Smell

If you smell gas, leave your home immediately. Here are some additional safety measures to follow if you suspect a gas leak:

• Get your family out of and away from your home immediately
• Do not turn on or off any light or any electrical appliance that can create a spark that can ignite the gas
• Do not turn on your stove or oven
• If you are able to open a few windows on your way out of your home, you may, but do not stick around to open windows
• Do not use your cell phone or landline phone
• If your car is garaged, leave it. Do not start your car or open the garage door. Either one can cause a spark that can cause the gas to ignite
• Call your local natural gas or propane provider
• Do not reenter your home until you have received an ok from your utility company and or the fire department
• Contact your local fire department to alert them of the gas leak. They may not be needed but if any fires erupt, you will want them close by to assist
