Common Furnace Problems We Fix
Furnaces are complex systems that have a lot of internal components. The particular components inside your furnace vary depending on whether it burns fuel to create heat or uses an electric heating element to heat your home. Some of the most common components to fail are heating elements, blower fan belts, capacitors, and flame sensors.
Here are key signs of a malfunction:
- Furnace not blowing warm air
- Short cycling or constantly turning on and off
- Strange noises or burning smells
- Pilot light or ignition issues
- Thermostat or airflow problems
