Why is My Gas Furnace Blowing Cold Air?

Heating

As the temps change, the more you feel the colder air blowing outside. And … right inside your house? If your gas furnace is blowing cold air and adding a chill to your Scottsboro home, it’s time to contact Southern Heating & Cooling Inc.. Sometimes the loss of warm air from your gas furnace results in a major repair, but many times it can be a simple fix. Here are several reasons your gas furnace might be blowing cold air instead of keeping your home toasty.

Your furnace may be overheating

If you haven’t had regular maintenance done on your gas furnace recently and you’ve overlooked changing your air filter, both could indicate 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 might overheat and force the burner to shut down.

Your pilot light may have gone out

It could be that 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, particularly with older furnaces, for a draft to smother 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 mean 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

When ducts are correctly 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.
