As the temps change, the more you feel the colder air blustering outside. And … right inside your house? If your gas furnace is blowing cold air and giving a chill to your Tucker home, it’s time to contact ACS Heating and Air Conditioning. Sometimes a lack of warm air from your gas furnace calls for a big repair, but often 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 keeping your home toasty.
Your furnace could be overheating
If you haven’t had regular maintenance done on your gas furnace lately and you’ve neglected to replace your air filter, both could signal 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 shut down its burner.
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 gust of air to extinguish 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 mean issues 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 struggle 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 properly 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.
