Common Issues
Experiencing issues with your Aire Flo furnace can be frustrating. Understanding common problems can help you troubleshoot effectively. This section covers some frequent issues with Aire Flo furnaces.
No Heat
If your furnace is not producing heat, check the thermostat settings. Ensure the thermostat is set to “heat” and the temperature is above room temperature. Also, inspect the circuit breaker. It might have tripped, cutting off power to the furnace.
