Why is My Gas Furnace Blowing Cold Air?

Heating

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 Middletown home, it’s time to contact Schagrin Gas Company. Sometimes the loss of warm air from your gas furnace results in a big repair, but often it can be a small 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 recently and you’ve neglected to replace your air filter, either could signal why your furnace is blowing cool air. A dirty air filter can block air from flowing freely through your furnace. If this occurs, the furnace might overheat and shut down its burner.

Your pilot light may have gone out

It could be that 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, especially with older systems, for a breeze to smother a pilot light. Other reasons for 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 appropriately cleaned. A dirty gas burner or flame sensor could cause your furnace to battle to stay lit and not be able to bring warmth to your home.

Your ducts may not be properly sealed

If your ducts aren’t sealed properly 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.
