Why is My Gas Furnace Blowing Cold Air?

As the seasons change, the more you feel the colder air blowing outside. And … in your home? If your gas furnace is blowing cold air and giving a chill to your Grimes home, it’s time to reach out to Heartland Heating & Cooling. Occasionally the loss of warm air from your gas furnace results in a big repair, but many times it can be a small fix. Here are several reasons your gas furnace may 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 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 this occurs, the furnace may overheat and cause the burner to shut down.

Your pilot light may have gone out

It’s probable a lack of warm air from your gas furnace can be attributed to something as simple as a pilot light that’s gone out. It’s possible, specifically with older furnaces, for a breeze 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 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 battle 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 might be losing a lot of heated air before it ever reaches your vents.
