Why is My Gas Furnace Blowing Cold Air?

As the temps change, the more you feel the colder air blustering outside. And … in your home? If your gas furnace is blowing cold air and giving a chill to your Grand Prairie home, it’s time to reach out to Mustang Mechanical. Occasionally the loss of warm air from your gas furnace results in a big repair, but many times it can be a simple fix. Here are some of the main 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 ongoing maintenance performed on your gas furnace for some time and you’ve overlooked changing your air filter, either could be the reason why your furnace is blowing cold air. A dirty air filter can stop air from flowing freely through your furnace. When this happens, 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 furnaces, for a breeze to extinguish a pilot light. Other reasons for 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 struggle 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 may be losing a lot of heated air before it can get to the vents.
