You come home from work on a chilly winter evening. Instead of expecting a warm and cozy home, you are faced with a chilly interior. What’s the issue? Was a window left open? Is there a draft somewhere? You hear your furnace running but notice the air isn’t hot–what could be the issue? There could be numerous reasons why your furnace is blowing out air that’s not hot and we are here to address a few of them.
This is a more common issue with a simple solution. Many homeowners have their thermostat fan setting to “on” rather than “auto.” Keeping the thermostat fan “on” will allow the fan to continuously run without providing heat. When you switch the thermostat to “auto” this allows the fan to run only when the furnace is running.
The pilot light may have gone out which is causing the cooler air. It could’ve gone out from something as simple as a gust of air.
A furnace that has overheated could be the reason why you’re feeling cold air. Changing the dirty filter can actually help solve this issue. Restricted airflow caused by a dirty filter can cause your furnace to shut off. Try changing your furnace’s air filter and restarting the unit and see if that fixes the issue.
