Why is My Gas Furnace Blowing Cold Air?

Heating

As the temps change, 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 Northwest Arkansas home, it’s time to call AirTech Heating and Air Conditioning, LLC. Once in a while the loss of warm air from your gas furnace results in a large repair, but many times it can be a simple fix. Here are several reasons your gas furnace may be blowing cold air instead of warming up your house.

Your furnace might be overheating

If you haven’t had regular maintenance performed on your gas furnace for some time and you’ve neglected to replace your air filter, both could signal why your furnace is blowing cold air. A dirty air filter can prevent air from flowing freely through your furnace. If that happens, the furnace could 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 related to something as simple as a pilot light that’s gone out. It’s possible, specifically with older furnaces, for a gust of air to put out 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 cause problems for your gas furnace, so can other furnace components if they aren’t appropriately cleaned. A dirty gas burner or flame sensor could cause your furnace to battle 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 may be losing a lot of heated air before it ever reaches your vents.
