What are common furnace problems?

Temperatures are starting to drop, bringing a noticeable chill to the evening air. Soon enough, you'll once again be relying heavily on your home's heating system to keep your family safe and comfortable. When you first suspect that your furnace isn't working properly, you'll want to call in an HVAC expert to conduct an inspection. At Air Controls, our experienced HVAC technicians are experts at diagnosing and repairing furnace problems. Give us a call if you notice any of the following symptoms of furnace trouble.

Issue with Blower Belt

The blower belt is a component of the motor that enables the fan to run properly. When your furnace's blower belt isn't working like it should, you may hear a squealing noise. Regular wear and tear can cause the blower belt to break or fray, which will likely require belt replacement to ensure that your furnace works efficiently.

Malfunctioning Thermostat

If your fan is continuously running, then you've got a sign of a problem with your thermostat. As your thermostat battery continues to run, your furnace may start to function with less efficiency. If you're noticing short cycling, then you could be due for thermostat replacement.

Clogged/Dirty Filter

By decreasing the intake your furnace requires to operate properly, a clogged/dirty filter can cause inefficiency. During periods of heavy wintertime usage, it's a good idea to change out your filter on a monthly basis.

Damaged Heat Exchanger

The heat exchanger does the important job of safely separating the combustion process from your breathing air. Heat exchangers may crack if you overheat your house or don't keep up with filter replacement. Typically, this means the technician will need to replace the heat exchanger.

Pilot Light Issues

Your pilot light should be a bright blue. If it burns any other color, then you'll want to give us a call because there could be excessive carbon monoxide in your gas furnace. If the flame is orange or yellow, then it may be burning inefficiently due to a lack of oxygen.
