Why is My Gas Furnace Blowing Cold Air?

As the weather changes, the more you feel the cool air blustering outside. And … right inside your house? If your gas furnace is blowing cold air and putting a chill to your Greensburg home, it’s time to call Wallpe Heating & Cooling. Once in a while an absence of warm air from your gas furnace calls for a major repair, but a lot of time it can be an easy fix. Here are several reasons your gas furnace could be blowing cold air instead of making your home warm and cozy.

Your furnace may be overheating

If you haven’t had ongoing maintenance completed on your gas furnace recently and you’ve neglected to replace your air filter, both could be the reason why your furnace is blowing cold air. A dirty air filter can stop air from flowing freely through your furnace. If this occurs, the furnace might overheat and cause the burner to shut down.

Your pilot light may have gone out

Sometimes 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, especially with older systems, for a gust of air to smother a pilot light. Other reasons for an extinguished pilot light are damaged 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 reduce the warmth inside your house.

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 could be losing a lot of heated air before it even reaches the vents throughout the home.
