Why is My Gas Furnace Blowing Cold Air?

As the weather changes, the more you feel the cool air blowing outside. And … inside 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 Heating and Cooling. 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 could be overheating

If you haven’t had regular maintenance completed on your gas furnace for some time and you’ve overlooked changing your air filter, each could signal why your furnace is blowing cool air. A dirty air filter can prevent air from flowing freely through your furnace. If this occurs, the furnace may 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, 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 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 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 might be losing a lot of heated air before it even reaches the vents throughout the home.
