Is Your Gas Furnace Acting Up? Troubleshooting Tips for Common Issues

gas furnace troubleshootingThough gas furnace diagnostics and repairs can be costly, some issues can be identified by knowledgeable homeowners. If your heating system is acting up, try these tips for troubleshooting a gas furnace. If these don’t identify and remedy the issue, contact your trusted HVAC professional to schedule a look.

Gas Furnace Produces No Heat

If the thermostat is set to a temperature that’s too cool, the furnace won’t get the signal to turn on. Set the thermostat to heat mode and move the dial a few degrees warmer to see if it kicks on. It’s also possible the furnace’s fuse is blown or the circuit breaker has tripped. Check both, resetting the circuit breaker or replacing the fuse if necessary. Finally, if the furnace’s pilot light has gone out, relight it.

Furnace Turns On and Off Too Frequently

This can happen if the air filter is dirty, so check it monthly and replace it when dirt begins accumulating. The furnace problem could also be with the thermostat; adjust the thermostat’s heat anticipator by moving it one calibration mark at the time toward the “longer” setting.

Noisy Operation

If your home’s furnace has a high pitch squealing while in operation, loose belts may be slipping. If a rumble or low-pitched growling sound is coming from the system, the gas burners may need cleaning. Either way, contact an experienced HVAC pro who can tackle these common gas furnace issues.

Gas Furnace Doesn’t Produce Enough Heat

Is airflow to the furnace’s combustion air chamber obstructed? This could be the issue, and an HVAC technician can help. Dirty gas burners could also be the cause, or the burners may just be out of alignment. A professional technician can clean and adjust the equipment in a standard furnace maintenance appointment.

Troubleshooting a gas furnace can help save both time and money, especially when the repairs can be made in house. To schedule professional service in your Macon area home, or for other home comfort concerns, contact Wilson Bryant Air Conditioning. We’re here to help!
