Why is My Gas Furnace Blowing Cold Air?

Heating

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 giving a chill to your Wharton home, it’s time to contact Faust Air Conditioning and Heating. Occasionally a lack of warm air from your gas furnace results in a large repair, but a lot of time it can be a simple 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 indicate 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 shut down its burner.

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, 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 damaged gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can mean challenges 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 struggle to stay lit and reduce the warmth inside your house.

Your ducts may not be properly sealed

When ducts are correctly sealed or if they have any cracks or holes in them, you could be losing a lot of heated air before it even reaches the vents throughout the home.
