Why is My Gas Furnace Blowing Cold Air?

As the temps change, the more you feel the cooler air blowing outside. And … inside your home? If your gas furnace is blowing cold air and adding a chill to your Excelsior Springs home, it’s time to contact Colvin's Heating and Cooling. Once in a while the loss of warm air from your gas furnace means a big repair, but often it can be an easy fix. Here are several reasons your gas furnace could be blowing cold air instead of keeping your home toasty.

Your furnace may be overheating

If you haven’t had regular maintenance performed on your gas furnace recently and you’ve forgotten to change your air filter, either could be the reason why your furnace is blowing cold air. A dirty air filter can prevent air from flowing freely through your furnace. If this occurs, 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 attributed to something as simple as a pilot light that’s gone out. It’s possible, specifically with older systems, for a gust of air to extinguish a pilot light. Other causes of an extinguished pilot light are defective gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can cause problems 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 fight 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.
