Troubleshoot Gas Furnace Problems Before Calling a Pro

Troubleshoot Gas Furnace Problems Before Calling a ProWhile a regularly maintained furnace that’s less than 10 to 15 years old should operate smoothly throughout the winter, there’s always a chance a problem may arise. As a result, it’s important to keep in mind some basic furnace troubleshooting tips. This way, you can check some accessible problem areas first and either fix the issue yourself or be better equipped to explain the problem to a trusted HVAC technician.

Troubleshooting Heating Problems

The Thermostat. If your heating system doesn’t work at all, the thermostat might be at fault. Check whether it has power and if it’s set properly to “heat.” If your thermostat operates with one or more batteries, make sure they’re working. If it’s wired to your HVAC system or household electricity, look at the breaker box to ensure the circuit hasn’t tripped.

Air Filters. If your furnace is not providing enough warm air, your air filter might be dirty. Check the filter, and if it looks clogged or dirty, replace or clean it. Inspect the filter monthly during the heating season; and depending on how dusty your home is, how much you’re using your furnace, whether you have long-haired pets and other factors, you might need to change the filter monthly. A clean filter will also help your furnace operate more efficiently, place less stress on furnace components and improve indoor air quality.

Ignition/Pilot Light. If you can’t get your gas or propane furnace to turn on, and have already ruled out the thermostat as the culprit, the issue could be in the ignition system. In an older furnace, this is called a pilot light, while newer furnaces are equipped with electronic igniters. Follow instructions to relight the pilot, or if you have an electronic igniter, follow instructions to reset the component.
