As the temps change, the more you feel the cool air blustering outside. And … in your home? If your gas furnace is blowing cold air and giving a chill to your Magnolia home, it’s time to contact JTech Mechanical. Sometimes a lack of warm air from your gas furnace calls for a large repair, but often it can be a small fix. Here are a few of the more common reasons your gas furnace may be blowing cold air instead of keeping your home toasty.
Your furnace may be overheating
If you haven’t had ongoing maintenance performed on your gas furnace recently and you’ve overlooked changing your air filter, both could be the reason why your furnace is blowing colder air. A dirty air filter can block 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 attributed to something as simple as a pilot light that’s gone out. It’s possible, particularly with older models, for a breeze 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 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 sealed properly 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.
