Why is My Gas Furnace Blowing Cold Air?

As the temps change, the more you feel the cool air gusting outside. And … right inside your house? If your gas furnace is blowing cold air and putting a chill to your Heflin home, it’s time to contact Bain Heating & Air Conditioning, Inc. Once in a while a lack of warm air from your gas furnace calls for a large repair, but many times it can be a small fix. Here are a few of the more common 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 routine maintenance completed on your gas furnace lately and you’ve overlooked changing your air filter, each could be the reason why your furnace is blowing colder air. A dirty air filter can stop air from flowing freely through your furnace. If that happens, the furnace could overheat and shut down its burner.

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 systems, for a gust of air to extinguish a pilot light. Other causes of an extinguished pilot light are faulty gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can cause problems for your gas furnace, so can other furnace components if they aren’t properly cleaned. A dirty gas burner or flame sensor could cause your furnace to fight to stay lit and not be able to bring warmth to your home.

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 can get to the vents.
