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 putting a chill to your Menomonie and western Wisconsin home, it’s time to contact Halverson Brothers Inc. Once in a while the loss of warm air from your gas furnace results in a large repair, but a lot of time it can be an easy fix. Here are several reasons your gas furnace may be blowing cold air instead of keeping your home toasty.

Your furnace might be overheating

If you haven’t had routine maintenance performed on your gas furnace lately and you’ve overlooked changing your air filter, both could be the reason why your furnace is blowing cool air. A dirty air filter can stop air from flowing freely through your furnace. If this occurs, the furnace may overheat and force 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, particularly with older systems, for a draft to smother a pilot light. Other factors when it comes to an extinguished pilot light are defective gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can result in problems 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 leave you in the cold.

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 may be losing a lot of heated air before it ever reaches your vents.
