Why is My Gas Furnace Blowing Cold Air?

November 13, 2018

As the seasons change, the more you feel the colder air blustering outside. And … inside your home? If your gas furnace is blowing cold air and adding a chill to your Booneville home, it’s time to reach out to Booneville Heating & Cooling LLC. Occasionally the loss of warm air from your gas furnace calls for a big repair, but often it can be a simple fix. Here are a few of the more common reasons your gas furnace may be blowing cold air instead of making your home warm and cozy.

Your furnace could be overheating

If you haven’t had routine maintenance performed on your gas furnace lately and you’ve overlooked changing your air filter, either could indicate why your furnace is blowing colder air. A dirty air filter can block air from flowing freely through your furnace. When this happens, the furnace might 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, particularly with older systems, for a breeze to smother a pilot light. Other reasons for an extinguished pilot light are defective gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can result in 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 battle to stay lit and not be able to bring warmth to your home.

Your ducts may not be properly sealed

When ducts are correctly sealed or if they have any cracks or holes in them, you might be losing a lot of heated air before it can get to the vents.
