Why is My Gas Furnace Blowing Cold Air?

As the temps change, the more you feel the cool air blowing outside. And … right inside your house? If your gas furnace is blowing cold air and putting a chill to your Saint Marys home, it’s time to contact Turner Brothers Heating & Air Conditioning. Occasionally the loss of warm air from your gas furnace calls for a major repair, but many times it can be a small fix. Here are several reasons your gas furnace might be blowing cold air instead of warming up your house.

Your furnace might be overheating

If you haven’t had regular maintenance performed on your gas furnace recently and you’ve neglected to replace your air filter, each could indicate 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 might overheat and force the burner to shut down.

Your pilot light may have gone out

Sometimes 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, especially with older systems, for a breeze to extinguish 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 result in problems 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 struggle 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 could be losing a lot of heated air before it ever reaches your vents.
