Why is My Gas Furnace Blowing Cold Air?

November 13, 2018

As the temps change, the more you feel the cool air blustering outside. And … in your home? If your gas furnace is blowing cold air and adding a chill to your Abilene home, it’s time to call Abilene Air-Tech Inc. Occasionally a lack of warm air from your gas furnace means a large repair, but a lot of time 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 might be overheating

If you haven’t had routine maintenance performed on your gas furnace recently and you’ve overlooked changing your air filter, either could be the reason why your furnace is blowing colder air. A dirty air filter can block air from flowing freely through your furnace. If this occurs, the furnace could overheat and shut down its burner.

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, specifically with older models, for a draft to smother a pilot light. Other factors when it comes to an extinguished pilot light are faulty 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 appropriately 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 properly sealed or if they have any cracks or holes in them, you might be losing a lot of heated air before it ever reaches your vents.
