Why is My Gas Furnace Blowing Cold Air?

As the temps change, the more you feel the cool air gusting outside. And … inside your home? If your gas furnace is blowing cold air and adding a chill to your Reinholds home, it’s time to contact County Line Mechanical LLC. Occasionally the loss of warm air from your gas furnace results in a large repair, but a lot of time it can be a simple fix. Here are a few of the more common reasons your gas furnace may be blowing cold air instead of warming up your house.

Your furnace may be overheating

If you haven’t had routine maintenance performed on your gas furnace for some time and you’ve overlooked changing your air filter, either could indicate why your furnace is blowing colder air. A dirty air filter can block 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’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 models, for a breeze to put out a pilot light. Other reasons for an extinguished pilot light are defective gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can mean issues for your gas furnace, so can other furnace components if they aren’t appropriately 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

If your ducts aren’t properly sealed or if they have any cracks or holes in them, you might be losing a lot of heated air before it even reaches the vents throughout the home.
