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 Alliance home, it’s time to contact Jack's Heating, Cooling, Stoves & Fireplaces. Sometimes a lack of warm air from your gas furnace results in a large repair, but a lot of time it can be a small fix. Here are several reasons your gas furnace could be blowing cold air instead of warming up your house.

Your furnace might be overheating

If you haven’t had regular maintenance done on your gas furnace lately and you’ve neglected to replace your air filter, both could signal why your furnace is blowing colder air. A dirty air filter can prevent air from flowing freely through your furnace. When this 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 credited to something as simple as a pilot light that’s gone out. It’s possible, specifically with older systems, for a breeze to extinguish a pilot light. Other factors when it comes to an extinguished pilot light are defective gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can cause 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 not be able to bring warmth to your home.

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 can get to the vents.
