Why is My Gas Furnace Blowing Cold Air?

As the temps change, the more you feel the colder air blustering outside. And … inside your home? If your gas furnace is blowing cold air and putting a chill to your Columbia home, it’s time to call Watts Electrical & Air Conditioning. Once in a while a lack of warm air from your gas furnace results in a big repair, but many times it can be a simple fix. Here are several reasons your gas furnace could 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 recently and you’ve neglected to replace your air filter, both could be the reason why your furnace is blowing cool air. A dirty air filter can prevent 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

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 systems, for a draft to smother 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 result in problems 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 struggle to stay lit and reduce the warmth inside your house.

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 could be losing a lot of heated air before it can get to the vents.
