Why is My Gas Furnace Blowing Cold Air?

As the temps change, the more you feel the cooler air blowing 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. Sometimes a lack of warm air from your gas furnace results in a large repair, but a lot of time it can be a small fix. Here are several reasons your gas furnace may be blowing cold air instead of keeping your home toasty.

Your furnace could be overheating

If you haven’t had ongoing maintenance completed on your gas furnace for some time and you’ve forgotten to change your air filter, both could signal why your furnace is blowing cold 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, specifically with older furnaces, for a gust of air to smother a pilot light. Other causes of an extinguished pilot light are faulty gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can cause problems 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 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.
