As the weather changes, the more you feel the cooler air blustering outside. And … in your home? If your gas furnace is blowing cold air and adding a chill to your Rapid City home, it’s time to call Precision Mechanical. Once in a while a lack of warm air from your gas furnace means a large repair, but often it can be an easy fix. Here are some of the main reasons your gas furnace may be blowing cold air instead of keeping your home toasty.
Your furnace might be overheating
If you haven’t had routine maintenance completed on your gas furnace for some time and you’ve neglected to replace your air filter, both could indicate why your furnace is blowing cold air. A dirty air filter can prevent air from flowing freely through your furnace. If this occurs, the furnace may overheat and shut down its burner.
Your pilot light may have gone out
It could be that a lack of warm air from your gas furnace can be attributed to something as simple as a pilot light that’s gone out. It’s possible, specifically with older systems, for a breeze 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 mean 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 fight to stay lit and leave you in the cold.
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 can get to the vents.
