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 Bountiful home, it’s time to call Craig's Heating & Cooling. Occasionally a lack of warm air from your gas furnace calls for a large repair, but many times it can be a small fix. Here are several reasons your gas furnace might be blowing cold air instead of making your home warm and cozy.

Your furnace might be overheating

If you haven’t had ongoing maintenance done on your gas furnace for some time and you’ve overlooked changing your air filter, each could signal why your furnace is blowing cool air. A dirty air filter can stop 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 could be that 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, specifically with older models, for a breeze to put out a pilot light. Other causes of an extinguished pilot light are defective 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 correctly 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

When ducts are correctly sealed or if they have any cracks or holes in them, you might be losing a lot of heated air before it ever reaches your vents.
