Why is My Gas Furnace Blowing Cold Air?

As the weather changes, the more you feel the cooler air blowing outside. And … inside your home? If your gas furnace is blowing cold air and putting a chill to your Bloomfield home, it’s time to call Stanford Heating & Cooling. Sometimes a lack of warm air from your gas furnace means a big repair, but a lot of time it can be an easy 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 signal why your furnace is blowing colder air. A dirty air filter can prevent air from flowing freely through your furnace. When this 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 related to something as simple as a pilot light that’s gone out. It’s possible, especially with older systems, for a breeze to put out a pilot light. Other reasons for 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 fight to stay lit and not be able to bring warmth to your home.

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.
