Why is My Gas Furnace Blowing Cold Air?

As the seasons change, the more you feel the cool air gusting outside. And … inside your home? If your gas furnace is blowing cold air and adding a chill to your Jefferson City home, it’s time to call Stieferman Heating Company Inc. Once in a while a lack of warm air from your gas furnace calls for a large 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 done on your gas furnace recently 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. When this happens, the furnace might overheat and shut down its burner.

Your pilot light may have gone out

It could be that a lack of warm air from your gas furnace can be credited to something as simple as a pilot light that’s gone out. It’s possible, particularly with older models, for a gust of air to put out 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 mean 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 sealed properly or if they have any cracks or holes in them, you may be losing a lot of heated air before it ever reaches your vents.
