Why is My Gas Furnace Blowing Cold Air?

As the weather changes, the more you feel the cool air blowing outside. And … right inside your house? If your gas furnace is blowing cold air and putting a chill to your Holdrege home, it’s time to call Durable Service . Sometimes a lack of warm air from your gas furnace calls for a large repair, but often it can be a small fix. Here are a few of the more common reasons your gas furnace may be blowing cold air instead of warming up your house.

Your furnace may be overheating

If you haven’t had ongoing maintenance completed on your gas furnace lately and you’ve forgotten to change your air filter, both could indicate why your furnace is blowing cold air. A dirty air filter can block air from flowing freely through your furnace. When this happens, the furnace could overheat and force the burner to shut down.

Your pilot light may have gone out

Sometimes 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, particularly with older models, for a breeze to smother a pilot light. Other factors when it comes to an extinguished pilot light are damaged 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 appropriately 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 sealed properly or if they have any cracks or holes in them, you might be losing a lot of heated air before it can get to the vents.
