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 Pflugerville home, it’s time to call Evenaire Heating & Air Conditioning. Once in a while a lack of warm air from your gas furnace calls for a major repair, but many times it can be an easy fix. Here are several reasons your gas furnace might 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 indicate why your furnace is blowing cool air. A dirty air filter can prevent air from flowing freely through your furnace. If this occurs, the furnace could 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 credited to something as simple as a pilot light that’s gone out. It’s possible, particularly with older furnaces, for a draft to put out a pilot light. Other causes of an extinguished pilot light are faulty gas valves or a faulty thermocouple.
Your furnace is dirty
Just as a dirty air filter can result in issues 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 struggle to stay lit and not be able to bring warmth to your home.
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.
