As the weather changes, the more you feel the cooler air blustering outside. And … inside your home? If your gas furnace is blowing cold air and adding a chill to your Ellsworth home, it’s time to contact Walter's-Eaton's Electric, Plumbing, Heating & AC. Sometimes the loss of warm air from your gas furnace results in a big repair, but often it can be an easy fix. Here are some of the main reasons your gas furnace might be blowing cold air instead of making your home warm and cozy.
Your furnace could be overheating
If you haven’t had ongoing maintenance done on your gas furnace lately and you’ve forgotten to change your air filter, each could indicate why your furnace is blowing cold air. A dirty air filter can block air from flowing freely through your furnace. If this occurs, the furnace might overheat and cause 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 furnaces, for a gust of air to smother a pilot light. Other causes of an extinguished pilot light are defective gas valves or a faulty thermocouple.
Your furnace is dirty
Just as a dirty air filter can mean 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 reduce the warmth inside your house.
Your ducts may not be properly sealed
If your ducts aren’t properly 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.
