Why is My Gas Furnace Blowing Cold Air?

Heating

As the temps change, the more you feel the cool air gusting outside. And … in your home? If your gas furnace is blowing cold air and adding a chill to your Kennesaw and surrounding areas home, it’s time to contact Total Comfort Solutions. Once in a while an absence of warm air from your gas furnace calls for a big repair, but a lot of time it can be an easy fix. Here are several reasons your gas furnace could be blowing cold air instead of making your home warm and cozy.

Your furnace could be overheating

If you haven’t had routine maintenance performed on your gas furnace recently and you’ve overlooked changing your air filter, either could indicate why your furnace is blowing colder air. A dirty air filter can prevent air from flowing freely through your furnace. If that happens, the furnace could overheat and cause the burner to shut down.

Your pilot light may have gone out

It’s probable 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, particularly with older systems, for a draft to extinguish a pilot light. Other factors when it comes to an extinguished pilot light are faulty gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can cause issues 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 reduce the warmth inside your house.

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.
