Why is My Gas Furnace Blowing Cold Air?

As the temps change, the more you feel the cooler air gusting outside. And … right inside your house? If your gas furnace is blowing cold air and adding a chill to your Wharton home, it’s time to contact Faust Air Conditioning and Heating. Occasionally an absence of warm air from your gas furnace results in a major repair, but many times it can be an easy fix. Here are several reasons your gas furnace might be blowing cold air instead of warming up your house.

Your furnace might be overheating

If you haven’t had routine maintenance done on your gas furnace lately and you’ve neglected to replace your air filter, each 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 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 furnaces, for a draft to put out a pilot light. Other factors when it comes to an extinguished pilot light are damaged 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 properly cleaned. A dirty gas burner or flame sensor could cause your furnace to fight to stay lit and reduce the warmth inside your house.

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 even reaches the vents throughout the home.
