Why is My Gas Furnace Blowing Cold Air?

As the weather changes, the more you feel the cooler air blustering 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 contact Durable Service . Occasionally an absence of warm air from your gas furnace calls for a major 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 could be overheating

If you haven’t had ongoing maintenance completed on your gas furnace lately and you’ve overlooked changing your air filter, either could signal 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 could overheat and force the burner to shut down.

Your pilot light may have gone out

It’s probable a lack of warm air from your gas furnace can be related 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 faulty 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 battle to stay lit and leave you in the cold.

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.
