Why is My Gas Furnace Blowing Cold Air?

Heating

As the seasons change, the more you feel the cool air blustering outside. And … in your home? If your gas furnace is blowing cold air and putting a chill to your Hattiesburg home, it’s time to call Oak Grove Heating & Air Conditioning. Once in a while the loss of warm air from your gas furnace calls for a major repair, but many times it can be a simple fix. Here are some of the main 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 routine maintenance done on your gas furnace lately and you’ve forgotten to change your air filter, both could signal why your furnace is blowing cold air. A dirty air filter can prevent air from flowing freely through your furnace. If this occurs, the furnace might overheat and force the burner to shut down.

Your pilot light may have gone out

It’s probable 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, particularly with older furnaces, for a draft to extinguish 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 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 struggle to stay lit and reduce the warmth inside your house.

Your ducts may not be properly sealed

When ducts are correctly 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.
