As the weather changes, the more you feel the cool air blustering outside. And … inside your home? If your gas furnace is blowing cold air and putting a chill to your Des Moines home, it’s time to contact Kohles & Bach Heating & Cooling. Occasionally the loss 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 could be blowing cold air instead of keeping your home toasty.
Your furnace might be overheating
If you haven’t had routine maintenance performed on your gas furnace recently and you’ve neglected to replace your air filter, either could signal why your furnace is blowing cool air. A dirty air filter can block 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
It’s probable 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 smother 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 mean challenges 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 battle to stay lit and leave you in the cold.
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 can get to the vents.
