As the temps change, the more you feel the cool air gusting outside. And … inside your home? If your gas furnace is blowing cold air and giving a chill to your Rapid City home, it’s time to reach out to Street Heating and Cooling. Once in a while a lack of warm air from your gas furnace means a large 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 routine maintenance done on your gas furnace lately and you’ve neglected to replace your air filter, both could signal why your furnace is blowing cold air. A dirty air filter can stop air from flowing freely through your furnace. If this occurs, the furnace could 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 related to something as simple as a pilot light that’s gone out. It’s possible, especially with older furnaces, for a draft to extinguish 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 issues for your gas furnace, so can other furnace components if they aren’t appropriately 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 might be losing a lot of heated air before it ever reaches your vents.
