Why is My Gas Furnace Blowing Cold Air?

Heating

As the weather changes, the more you feel the colder air blustering outside. And … right inside your house? If your gas furnace is blowing cold air and adding a chill to your Manassas Park home, it’s time to reach out to Woody's Sudden Service Inc. Sometimes a lack of warm air from your gas furnace results in a big repair, but often it can be a simple fix. Here are several reasons your gas furnace might be blowing cold air instead of making your home warm and cozy.

Your furnace may be overheating

If you haven’t had routine maintenance performed on your gas furnace lately and you’ve overlooked changing your air filter, either could be the reason why your furnace is blowing cool air. A dirty air filter can block air from flowing freely through your furnace. When this happens, 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 related to something as simple as a pilot light that’s gone out. It’s possible, specifically with older systems, for a draft to put out 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 mean issues 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 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 might be losing a lot of heated air before it even reaches the vents throughout the home.
