Why is My Gas Furnace Blowing Cold Air?

As the seasons change, the more you feel the cooler air blustering outside. And … inside your home? If your gas furnace is blowing cold air and putting a chill to your Wisconsin Rapids home, it’s time to reach out to Rapids Sheet Metal Works Inc. Occasionally a lack of warm air from your gas furnace results in a major repair, but a lot of time it can be a small fix. Here are some of the main reasons your gas furnace might be blowing cold air instead of making your home warm and cozy.

Your furnace may be overheating

If you haven’t had ongoing maintenance done on your gas furnace for some time and you’ve overlooked changing your air filter, both could signal 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 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 credited to something as simple as a pilot light that’s gone out. It’s possible, specifically with older furnaces, for a draft to smother a pilot light. Other causes of an extinguished pilot light are damaged 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 battle 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 properly sealed or if they have any cracks or holes in them, you might be losing a lot of heated air before it ever reaches your vents.
