Why is My Gas Furnace Blowing Cold Air?

As the weather changes, the more you feel the cooler air blustering outside. And … in your home? If your gas furnace is blowing cold air and putting a chill to your Bloomfield home, it’s time to contact Stanford Heating & Cooling. Occasionally a lack of warm air from your gas furnace calls for a big repair, but a lot of time it can be a simple fix. Here are a few of the more common reasons your gas furnace could be blowing cold air instead of keeping your home toasty.

Your furnace could be overheating

If you haven’t had routine maintenance done on your gas furnace for some time and you’ve overlooked changing your air filter, either could indicate why your furnace is blowing colder air. A dirty air filter can stop air from flowing freely through your furnace. If this occurs, the furnace could 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 attributed to something as simple as a pilot light that’s gone out. It’s possible, particularly with older systems, for a breeze 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 cause 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 fight 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 could be losing a lot of heated air before it can get to the vents.
