Why is My Gas Furnace Blowing Cold Air?

Heating

As the temps change, the more you feel the cooler air gusting outside. And … in your home? If your gas furnace is blowing cold air and putting a chill to your Branchville home, it’s time to call Willco Air Conditioning, Refrigeration & Heating Inc.. Sometimes the loss of warm air from your gas furnace results in a big repair, but often it can be a simple fix. Here are several 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 ongoing maintenance done on your gas furnace recently and you’ve neglected to replace your air filter, each could signal why your furnace is blowing cool air. A dirty air filter can stop air from flowing freely through your furnace. If this occurs, 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, especially with older furnaces, for a gust of air to put out a pilot light. Other reasons for an extinguished pilot light are damaged gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can result in challenges 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 might be losing a lot of heated air before it can get to the vents.
