Why is My Gas Furnace Blowing Cold Air?

November 13, 2018

As the weather changes, the more you feel the colder air blustering outside. And … in your home? If your gas furnace is blowing cold air and adding a chill to your Crestview home, it’s time to reach out to Gordon Air Conditioning. Once in a while an absence of warm air from your gas furnace calls for a big repair, but a lot of time it can be a simple fix. Here are several reasons your gas furnace may be blowing cold air instead of making your home warm and cozy.

Your furnace could be overheating

If you haven’t had regular maintenance performed on your gas furnace lately and you’ve overlooked changing your air filter, each could be the reason 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 cause the burner to shut down.

Your pilot light may have gone out

Sometimes 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, especially with older systems, for a draft to smother 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 issues for your gas furnace, so can other furnace components if they aren’t appropriately cleaned. A dirty gas burner or flame sensor could cause your furnace to struggle 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 can get to the vents.
