Why is My Gas Furnace Blowing Cold Air?

As the temps change, the more you feel the cool air blowing outside. And … inside your home? If your gas furnace is blowing cold air and putting a chill to your Rapid City home, it’s time to reach out to Street Heating and Cooling. Sometimes the loss of warm air from your gas furnace calls for a big repair, but many times it can be a small fix. Here are a few of the more common 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 for some time and you’ve overlooked changing your air filter, both could indicate why your furnace is blowing cold air. A dirty air filter can prevent air from flowing freely through your furnace. If this occurs, the furnace may overheat and shut down its burner.

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, specifically with older furnaces, for a breeze to smother a pilot light. Other causes of an extinguished pilot light are damaged 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 correctly cleaned. A dirty gas burner or flame sensor could cause your furnace to struggle 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 might be losing a lot of heated air before it even reaches the vents throughout the home.
