As the weather changes, the more you feel the cool air gusting outside. And … in your home? If your gas furnace is blowing cold air and adding a chill to your Wisconsin Rapids home, it’s time to contact Rapids Sheet Metal Works Inc. Occasionally the loss of warm air from your gas furnace means a major repair, but a lot of time it can be a simple fix. Here are a few of the more common reasons your gas furnace could be blowing cold air instead of keeping your home toasty.
Your furnace could be overheating
If you haven’t had regular maintenance done on your gas furnace lately and you’ve overlooked changing your air filter, both could signal why your furnace is blowing colder air. A dirty air filter can block air from flowing freely through your furnace. When this happens, 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 attributed to something as simple as a pilot light that’s gone out. It’s possible, specifically with older models, for a breeze 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 cause 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 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 might be losing a lot of heated air before it ever reaches your vents.
