As the weather changes, the more you feel the cooler air gusting outside. And … right inside your house? If your gas furnace is blowing cold air and putting a chill to your West Jefferson home, it’s time to contact West Jefferson Plumbing and Heating, Inc.. Occasionally a lack of warm air from your gas furnace means a big repair, but a lot of time it can be a small fix. Here are a few of the more common reasons your gas furnace may be blowing cold air instead of warming up your house.
Your furnace could be overheating
If you haven’t had routine maintenance completed on your gas furnace for some time and you’ve overlooked changing your air filter, either could indicate why your furnace is blowing cool air. A dirty air filter can prevent air from flowing freely through your furnace. If this occurs, 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 credited to something as simple as a pilot light that’s gone out. It’s possible, especially with older systems, for a draft to put out a pilot light. Other causes of 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 challenges 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 battle 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 may be losing a lot of heated air before it even reaches the vents throughout the home.
