Why is My Gas Furnace Blowing Cold Air?

Heating

As the temps change, the more you feel the cool air gusting outside. And … right inside your house? If your gas furnace is blowing cold air and putting a chill to your Waxahachie home, it’s time to reach out to C&C Refrigeration Inc.. Occasionally a lack of warm air from your gas furnace calls for a major repair, but often it can be a small fix. Here are some of the main reasons your gas furnace could be blowing cold air instead of making your home warm and cozy.

Your furnace might be overheating

If you haven’t had regular maintenance done on your gas furnace lately and you’ve forgotten to change your air filter, both could signal why your furnace is blowing cool air. A dirty air filter can stop 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 systems, for a draft to smother a pilot light. Other reasons for 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 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 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 might be losing a lot of heated air before it can get to the vents.
