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 giving a chill to your Hickory home, it’s time to reach out to Climate Control Systems. Occasionally the loss of warm air from your gas furnace results in a large repair, but a lot of time it can be a small 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 might be overheating

If you haven’t had regular maintenance done on your gas furnace recently and you’ve neglected to replace your air filter, both could signal why your furnace is blowing cold air. A dirty air filter can stop air from flowing freely through your furnace. If that happens, 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, particularly with older models, for a gust of air to extinguish 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 mean problems 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 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 may be losing a lot of heated air before it even reaches the vents throughout the home.
