As the weather changes, the more you feel the cooler air blustering outside. And … right inside your house? If your gas furnace is blowing cold air and adding a chill to your Hamilton home, it’s time to contact Carefree Heating and Cooling, LLC. Sometimes a lack of warm air from your gas furnace calls for a large repair, but often it can be a simple fix. Here are a few of the more common reasons your gas furnace may be blowing cold air instead of warming up your house.
Your furnace might be overheating
If you haven’t had regular maintenance performed on your gas furnace recently and you’ve forgotten to change your air filter, both could indicate why your furnace is blowing colder air. A dirty air filter can prevent air from flowing freely through your furnace. If that happens, the furnace may overheat and shut down its burner.
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 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 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 can get to the vents.
