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 adding a chill to your Tuscaloosa home, it’s time to contact KDM Service Corporation. Once in a while the loss of warm air from your gas furnace results in a major repair, but many times it can be a small fix. Here are several reasons your gas furnace might be blowing cold air instead of keeping your home toasty.

Your furnace might be overheating

If you haven’t had ongoing maintenance completed on your gas furnace lately and you’ve neglected to replace your air filter, both could be the reason why your furnace is blowing cool 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 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 models, for a gust of air to extinguish 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 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 struggle 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.
