As the seasons change, the more you feel the cooler air gusting outside. And … inside your home? If your gas furnace is blowing cold air and giving a chill to your Lexington home, it’s time to contact James Heating & A/C, Inc. Once in a while the loss of warm air from your gas furnace means a major repair, but often it can be a simple fix. Here are several reasons your gas furnace may be blowing cold air instead of making your home warm and cozy.
Your furnace may be overheating
If you haven’t had regular maintenance completed on your gas furnace recently and you’ve forgotten to change your air filter, each could be the reason why your furnace is blowing cold air. A dirty air filter can prevent air from flowing freely through your furnace. When this happens, the furnace may overheat and cause 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 attributed to something as simple as a pilot light that’s gone out. It’s possible, particularly with older models, for a draft to extinguish a pilot light. Other factors when it comes to an extinguished pilot light are damaged gas valves or a faulty thermocouple.
Your furnace is dirty
Just as a dirty air filter can result in 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 fight 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.
