Why is My Gas Furnace Blowing Cold Air?

Heating

As the weather changes, the more you feel the cooler air blustering outside. And … in your home? If your gas furnace is blowing cold air and adding a chill to your Columbus home, it’s time to reach out to Wolfe & Sons Inc. Sometimes an absence of warm air from your gas furnace calls for a big repair, but a lot of time it can be a small fix. Here are a few of the more common reasons your gas furnace could be blowing cold air instead of warming up your house.

Your furnace may be overheating

If you haven’t had regular maintenance completed on your gas furnace for some time and you’ve forgotten to change 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. When this happens, the furnace may 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, specifically with older furnaces, for a draft to extinguish a pilot light. Other causes of an extinguished pilot light are defective gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can cause 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 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 could be losing a lot of heated air before it even reaches the vents throughout the home.
