Why is My Gas Furnace Blowing Cold Air?

Heating

As the seasons change, the more you feel the colder air gusting outside. And … right inside your house? If your gas furnace is blowing cold air and adding a chill to your Belton home, it’s time to contact Bell Air Conditioning Inc.. Sometimes the loss of warm air from your gas furnace results in a large repair, but often it can be a small fix. Here are a few of the more common reasons your gas furnace might be blowing cold air instead of keeping your home toasty.

Your furnace could be overheating

If you haven’t had regular maintenance completed on your gas furnace lately and you’ve overlooked changing your air filter, both could signal why your furnace is blowing cold air. A dirty air filter can stop air from flowing freely through your furnace. If that happens, the furnace may overheat and force 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, especially with older models, for a draft to smother a pilot light. Other causes of an extinguished pilot light are damaged gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can mean problems 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 not be able to bring warmth to your home.

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 can get to the vents.
