Why is My Gas Furnace Blowing Cold Air?

As the weather changes, the more you feel the cool air gusting outside. And … right inside your house? If your gas furnace is blowing cold air and putting a chill to your Macon home, it’s time to contact Air Temperature Control. Occasionally the loss of warm air from your gas furnace calls for a major repair, but often it can be a simple fix. Here are some of the main reasons your gas furnace could be blowing cold air instead of keeping your home toasty.

Your furnace might be overheating

If you haven’t had routine maintenance done on your gas furnace for some time and you’ve overlooked changing your air filter, each could indicate why your furnace is blowing cold air. A dirty air filter can stop air from flowing freely through your furnace. When this happens, the furnace could overheat and cause the burner to shut down.

Your pilot light may have gone out

Sometimes a lack of warm air from your gas furnace can be credited to something as simple as a pilot light that’s gone out. It’s possible, specifically with older systems, for a breeze to smother a pilot light. Other factors when it comes to an extinguished pilot light are damaged gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can cause issues for your gas furnace, so can other furnace components if they aren’t properly cleaned. A dirty gas burner or flame sensor could cause your furnace to fight to stay lit and leave you in the cold.

Your ducts may not be properly sealed

If your ducts aren’t properly sealed or if they have any cracks or holes in them, you might be losing a lot of heated air before it can get to the vents.
