As the seasons change, the more you feel the cooler air blustering outside. And … inside your home? If your gas furnace is blowing cold air and adding a chill to your Tucson home, it’s time to contact Ambient Air. Once in a while an absence of warm air from your gas furnace results in a major repair, but a lot of time it can be a simple fix. Here are some of the main reasons your gas furnace could be blowing cold air instead of keeping your home toasty.
Your furnace may be overheating
If you haven’t had routine maintenance completed on your gas furnace for some time and you’ve neglected to replace your air filter, both could be the reason why your furnace is blowing colder air. A dirty air filter can stop air from flowing freely through your furnace. If this occurs, the furnace might overheat and shut down its burner.
Your pilot light may have gone out
It’s probable a lack of warm air from your gas furnace can be related to something as simple as a pilot light that’s gone out. It’s possible, especially with older systems, 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 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 fight to stay lit and reduce the warmth inside your house.
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 even reaches the vents throughout the home.
