Furnace Blowing Cool Air? Don’t Sweat It Yet

An essential part of maintaining a comfortable home environment is having a furnace that’s functioning properly. Regular furnace tune-ups help with identifying any possible trouble with your appliance, so you can have minor problems resolved or find out if a furnace replacement is required. A common problem that may alter your level of comfort during the cold season is having your furnace blowing cool air. Before you call for professional help, here are the main causes and some possible solutions that you can try yourself:

  • The temperature on the thermostat is set too low – in this case, the thermostat may not be calling for heat, so you need to check if it’s properly set on heat mode and adjust the temperature settings.
  • The furnace has a clogged filter – if you haven’t changed the filter in a while, it might have become clogged, blocking the airflow. When operating with a clogged filter, some devices are designed to shut down the burner to avoid overheating, so the fan will blow cool air. Changing the filter is easy to do and will restore your furnace to its normal functioning.
  • The circuit breaker or fuse that controls your device is tripped or blown – this can be easily fixed by replacing the blown fuse or resetting the circuit breaker. The circuit breaker can be reset by accessing your electrical panel and pushing the lever to the “on” position.
  • There’s a glitch in the system – if you own a more modern furnace that is computer controlled, a quick system reboot might fix the problem. To do that, you simply turn the device’s main switch to the “off” position and flip it back on after 30 seconds. If you’ve already tried troubleshooting your furnace without any luck, then it’s time to seek professional help.
