Why is My Gas Furnace Blowing Cold Air?

Heating

As the seasons change, the more you feel the cool air gusting outside. And … in your home? If your gas furnace is blowing cold air and putting a chill to your Oxford home, it’s time to reach out to Franklin's Heating & Air Conditioning, Inc.. Sometimes a lack of warm air from your gas furnace calls for a major repair, but often 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 ongoing maintenance done on your gas furnace for some time and you’ve forgotten to change 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 may overheat and force 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 attributed to something as simple as a pilot light that’s gone out. It’s possible, specifically with older models, for a gust of air 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 mean challenges for your gas furnace, so can other furnace components if they aren’t correctly cleaned. A dirty gas burner or flame sensor could cause your furnace to fight to stay lit and not be able to bring warmth to your home.

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 could be losing a lot of heated air before it ever reaches your vents.
