As the weather changes, the more you feel the colder air blowing outside. And … inside your home? If your gas furnace is blowing cold air and giving a chill to your Redford home, it’s time to contact Airtronic Heating & Cooling. Once in a while the loss of warm air from your gas furnace calls for a big repair, but a lot of time it can be a small fix. Here are several reasons your gas furnace may be blowing cold air instead of warming up your house.
Your furnace could be overheating
If you haven’t had ongoing maintenance done on your gas furnace lately and you’ve overlooked changing your air filter, either could be the reason 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 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 breeze to put out a pilot light. Other reasons for an extinguished pilot light are faulty gas valves or a faulty thermocouple.
Your furnace is dirty
Just as a dirty air filter can cause challenges 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 struggle to stay lit and reduce the warmth inside your house.
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.
