As the seasons change, the more you feel the cooler air blustering outside. And … right inside your house? If your gas furnace is blowing cold air and giving a chill to your Lake Worth home, it’s time to call Smyth Air Conditioning Inc. Once in a while an absence of warm air from your gas furnace calls for a large repair, but many times it can be an easy fix. Here are a few of the more common reasons your gas furnace might be blowing cold air instead of making your home warm and cozy.
Your furnace may be overheating
If you haven’t had ongoing maintenance performed on your gas furnace for some time and you’ve forgotten to change your air filter, both could signal why your furnace is blowing cool air. A dirty air filter can stop air from flowing freely through your furnace. If that happens, the furnace could overheat and force the burner to shut down.
Your pilot light may have gone out
It could be that 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 systems, for a draft to smother a pilot light. Other reasons for an extinguished pilot light are defective gas valves or a faulty thermocouple.
Your furnace is dirty
Just as a dirty air filter can mean 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 not be able to bring warmth to your home.
Your ducts may not be properly sealed
If your ducts aren’t sealed properly or if they have any cracks or holes in them, you could be losing a lot of heated air before it ever reaches your vents.
