As the weather changes, the more you feel the cooler air gusting outside. And … inside your home? If your gas furnace is blowing cold air and adding a chill to your Rock Hill home, it’s time to reach out to US Air Heating and Cooling. Occasionally a lack of warm air from your gas furnace means a major repair, but many times it can be an easy fix. Here are a few of the more common reasons your gas furnace could be blowing cold air instead of warming up your house.
Your furnace could be overheating
If you haven’t had regular maintenance performed on your gas furnace lately and you’ve overlooked changing your air filter, either could signal why your furnace is blowing colder air. A dirty air filter can block air from flowing freely through your furnace. If that happens, the furnace may overheat and force 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 attributed to something as simple as a pilot light that’s gone out. It’s possible, particularly with older systems, for a breeze to smother a pilot light. Other reasons for an extinguished pilot light are damaged gas valves or a faulty thermocouple.
Your furnace is dirty
Just as a dirty air filter can mean problems 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 leave you in the cold.
Your ducts may not be properly sealed
If your ducts aren’t sealed properly or if they have any cracks or holes in them, you may be losing a lot of heated air before it ever reaches your vents.
