As the temps change, the more you feel the colder air blowing outside. And … right inside your house? If your gas furnace is blowing cold air and giving a chill to your Huffman home, it’s time to reach out to Air Houston Mechanical LLC. Once in a while the loss of warm air from your gas furnace means a large repair, but many times it can be an easy fix. Here are some of the main reasons your gas furnace may be blowing cold air instead of warming up your house.
Your furnace might be overheating
If you haven’t had routine maintenance performed on your gas furnace for some time and you’ve forgotten to change your air filter, either could be the reason why your furnace is blowing colder air. A dirty air filter can stop air from flowing freely through your furnace. When this happens, the furnace might overheat and force 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, specifically with older furnaces, for a draft to put out a pilot light. Other reasons for an extinguished pilot light are faulty gas valves or a faulty thermocouple.
Your furnace is dirty
Just as a dirty air filter can mean challenges 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 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 can get to the vents.
