Why is My Gas Furnace Blowing Cold Air?

Heating

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 adding a chill to your Bloomington home, it’s time to reach out to All Seasons Heating & A/C Co. Occasionally a lack of warm air from your gas furnace results in a major repair, but often it can be a simple fix. Here are several reasons your gas furnace could be blowing cold air instead of warming up your house.

Your furnace might be overheating

If you haven’t had ongoing maintenance performed on your gas furnace for some time and you’ve overlooked changing your air filter, either could be the reason why your furnace is blowing cold air. A dirty air filter can block air from flowing freely through your furnace. If that happens, the furnace may overheat and cause 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 credited 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 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 result in problems 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 fight 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 could be losing a lot of heated air before it can get to the vents.
