Why is My Gas Furnace Blowing Cold Air?

As the seasons change, the more you feel the colder air blowing outside. And … in your home? If your gas furnace is blowing cold air and adding a chill to your Middletown home, it’s time to call Schagrin Gas Company. Occasionally 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 might 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 lately and you’ve neglected to replace your air filter, both could indicate why your furnace is blowing cool air. A dirty air filter can block air from flowing freely through your furnace. When this happens, the furnace might overheat and cause the burner to shut down.

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 models, for a breeze to smother 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 cause 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.
