Why is My Gas Furnace Blowing Cold Air?

As the weather changes, the more you feel the colder air gusting outside. And … inside your home? If your gas furnace is blowing cold air and giving a chill to your Savage home, it’s time to call Gopher Heating and Air Conditioning. Once in a while the loss of warm air from your gas furnace means a large repair, but often it can be a small fix. Here are some of the main reasons your gas furnace may be blowing cold air instead of keeping your home toasty.

Your furnace may be overheating

If you haven’t had routine maintenance completed on your gas furnace for some time and you’ve neglected to replace your air filter, both could signal why your furnace is blowing colder air. A dirty air filter can stop air from flowing freely through your furnace. If that happens, the furnace may 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 related to something as simple as a pilot light that’s gone out. It’s possible, especially with older furnaces, for a draft 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 properly 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 could be losing a lot of heated air before it can get to the vents.
