Why is My Gas Furnace Blowing Cold Air?

Heating

As the temps change, the more you feel the cooler air blustering outside. And … in your home? If your gas furnace is blowing cold air and giving a chill to your East Hanover home, it’s time to call Effective Service Group, LLC. Once in a while a lack of warm air from your gas furnace means a large repair, but many times it can be an easy fix. Here are several reasons your gas furnace could be blowing cold air instead of making your home warm and cozy.

Your furnace could be overheating

If you haven’t had regular maintenance completed on your gas furnace lately and you’ve overlooked changing your air filter, either could signal why your furnace is blowing cool air. A dirty air filter can prevent 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 credited to something as simple as a pilot light that’s gone out. It’s possible, specifically with older furnaces, for a breeze to put out a pilot light. Other factors when it comes to 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 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 battle to stay lit and reduce the warmth inside your house.

Your ducts may not be properly sealed

If your ducts aren’t properly sealed 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.
