Why is My Gas Furnace Blowing Cold Air?

Heating

As the weather changes, the more you feel the cooler 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 call Air Temperature Control. Sometimes the loss of warm air from your gas furnace means a large repair, but often it can be an easy fix. Here are some of the main reasons your gas furnace could be blowing cold air instead of making your home warm and cozy.

Your furnace might be overheating

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

Your pilot light may have gone out

It’s probable 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 faulty gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can mean issues for your gas furnace, so can other furnace components if they aren’t correctly cleaned. A dirty gas burner or flame sensor could cause your furnace to struggle 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 could be losing a lot of heated air before it ever reaches your vents.
