Why is My Gas Furnace Blowing Cold Air?

As the temps change, the more you feel the cooler air gusting outside. And … inside your home? If your gas furnace is blowing cold air and putting a chill to your McMurray home, it’s time to contact Kowalski Heating, Cooling & Plumbing. Sometimes the loss of warm air from your gas furnace means a major repair, but many times it can be a small fix. Here are some of the main reasons your gas furnace may be blowing cold air instead of making your home warm and cozy.

Your furnace may be overheating

If you haven’t had regular maintenance done on your gas furnace recently and you’ve neglected to replace 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 that happens, the furnace could overheat and force the burner to shut down.

Your pilot light may have gone out

Sometimes a lack of warm air from your gas furnace can be credited to something as simple as a pilot light that’s gone out. It’s possible, particularly with older furnaces, for a gust of air to smother a pilot light. Other reasons for an extinguished pilot light are faulty gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can result in 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 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.
