As the seasons change, the more you feel the cooler air blowing outside. And … in your home? If your gas furnace is blowing cold air and giving a chill to your Montoursville home, it’s time to reach out to Airmen HVAC Service. Occasionally a lack of warm air from your gas furnace results in a major repair, but a lot of time it can be an easy fix. Here are several reasons your gas furnace may be blowing cold air instead of keeping your home toasty.
Your furnace could be overheating
If you haven’t had regular maintenance performed on your gas furnace recently and you’ve forgotten to change your air filter, both could indicate why your furnace is blowing colder air. A dirty air filter can prevent air from flowing freely through your furnace. If this occurs, the furnace may overheat and cause 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 credited to something as simple as a pilot light that’s gone out. It’s possible, specifically with older systems, for a draft to put out a pilot light. Other factors when it comes to an extinguished pilot light are defective gas valves or a faulty thermocouple.
Your furnace is dirty
Just as a dirty air filter can cause 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 fight 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 could be losing a lot of heated air before it even reaches the vents throughout the home.
