Why is My Gas Furnace Blowing Cold Air?

November 13, 2018

As the temps change, the more you feel the cooler air blustering outside. And … right inside your house? If your gas furnace is blowing cold air and giving a chill to your Plover home, it’s time to call Point Heating & Cooling. Occasionally the loss of warm air from your gas furnace results in a major repair, but often it can be a simple fix. Here are a few of the more common reasons your gas furnace might be blowing cold air instead of making your home warm and cozy.

Your furnace could be overheating

If you haven’t had regular maintenance done on your gas furnace recently and you’ve forgotten to change your air filter, either could indicate why your furnace is blowing colder air. A dirty air filter can block air from flowing freely through your furnace. If that happens, the furnace might 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 related to something as simple as a pilot light that’s gone out. It’s possible, especially with older systems, for a breeze to extinguish 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 cause challenges 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

If your ducts aren’t sealed properly or if they have any cracks or holes in them, you may be losing a lot of heated air before it even reaches the vents throughout the home.
