Why is My Gas Furnace Blowing Cold Air?

Heating

As the temps change, the more you feel the cool air blowing outside. And … in your home? If your gas furnace is blowing cold air and putting a chill to your Huffman home, it’s time to reach out to Air Houston Mechanical LLC. Once in a while an absence of warm air from your gas furnace means a major repair, but often it can be a small fix. Here are some of the main reasons your gas furnace might 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 lately and you’ve forgotten to change your air filter, each 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 shut down its burner.

Your pilot light may have gone out

Sometimes a lack of warm air from your gas furnace can be attributed to something as simple as a pilot light that’s gone out. It’s possible, particularly with older models, for a breeze to put out 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 issues for your gas furnace, so can other furnace components if they aren’t properly 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

If your ducts aren’t sealed properly 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.
