Why is My Gas Furnace Blowing Cold Air?

Heating

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 West Valley home, it’s time to call Select Comfort System Heating & Air Conditioning. Sometimes the loss of warm air from your gas furnace results in a big repair, but often 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 could be overheating

If you haven’t had routine maintenance completed on your gas furnace lately and you’ve forgotten to change your air filter, both could signal why your furnace is blowing cold air. A dirty air filter can block air from flowing freely through your furnace. If this occurs, the furnace could overheat and force the burner to shut down.

Your pilot light may have gone out

It’s probable a lack of warm air from your gas furnace can be attributed to something as simple as a pilot light that’s gone out. It’s possible, especially with older systems, for a gust of air to put out a pilot light. Other factors when it comes to an extinguished pilot light are damaged 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 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

When ducts are correctly sealed or if they have any cracks or holes in them, you might be losing a lot of heated air before it ever reaches your vents.
