Why is My Gas Furnace Blowing Cold Air?

November 13, 2018

As the temps change, the more you feel the colder air blustering outside. And … right inside your house? If your gas furnace is blowing cold air and putting a chill to your Bartlesville home, it’s time to call Farris Heating & Air. Sometimes an absence of warm air from your gas furnace calls for a large repair, but many times it can be a simple fix. Here are a few of the more common 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 forgotten to change your air filter, both could indicate why your furnace is blowing cold air. A dirty air filter can stop air from flowing freely through your furnace. If this occurs, the furnace may overheat and force 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 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 reasons for an extinguished pilot light are defective gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can cause 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 fight to stay lit and leave you in the cold.

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.
