Why is My Gas Furnace Blowing Cold Air?

As the temps change, the more you feel the cooler air gusting outside. And … right inside your house? If your gas furnace is blowing cold air and adding a chill to your Keokuk home, it’s time to contact WM J Kraus & Son. Sometimes an absence of warm air from your gas furnace means a big repair, but many times it can be a simple fix. Here are some of the main reasons your gas furnace might be blowing cold air instead of warming up your house.

Your furnace could be overheating

If you haven’t had regular maintenance completed on your gas furnace lately and you’ve forgotten to change your air filter, each could be the reason why your furnace is blowing cool air. A dirty air filter can block air from flowing freely through your furnace. If this occurs, the furnace may overheat and shut down its burner.

Your pilot light may have gone out

It’s probable 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, especially with older models, for a breeze to put out 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 cause issues 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 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 could be losing a lot of heated air before it can get to the vents.
