Why is My Gas Furnace Blowing Cold Air?

Heating

As the weather changes, the more you feel the colder air blustering outside. And … in your home? If your gas furnace is blowing cold air and adding a chill to your Augusta home, it’s time to call McCune Heating & Cooling. Sometimes the loss of warm air from your gas furnace results in a major repair, but a lot of time it can be a simple fix. Here are some of the main reasons your gas furnace could be blowing cold air instead of warming up your house.

Your furnace may be overheating

If you haven’t had ongoing maintenance done on your gas furnace recently and you’ve forgotten to change your air filter, either could signal 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 may 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 systems, for a draft to put out a pilot light. Other factors when it comes to an extinguished pilot light are defective gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can cause issues for your gas furnace, so can other furnace components if they aren’t correctly cleaned. A dirty gas burner or flame sensor could cause your furnace to struggle to stay lit and leave you in the cold.

Your ducts may not be properly sealed

If your ducts aren’t sealed properly or if they have any cracks or holes in them, you could be losing a lot of heated air before it ever reaches your vents.
