Why is My Gas Furnace Blowing Cold Air?

Heating

As the seasons change, the more you feel the cooler air gusting outside. And … right inside your house? If your gas furnace is blowing cold air and putting a chill to your Chatsworth home, it’s time to call True Temp Heating & Air Inc. Occasionally the loss of warm air from your gas furnace results in a major repair, but a lot of time it can be a small fix. Here are several reasons your gas furnace could be blowing cold air instead of warming up your house.

Your furnace could be overheating

If you haven’t had ongoing maintenance completed on your gas furnace for some time and you’ve neglected to replace your air filter, each could indicate why your furnace is blowing colder air. A dirty air filter can stop 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, specifically with older systems, for a draft to extinguish a pilot light. Other causes of an extinguished pilot light are damaged 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 correctly cleaned. A dirty gas burner or flame sensor could cause your furnace to battle to stay lit and leave you in the cold.

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 can get to the vents.
