As the seasons change, the more you feel the cool air blustering outside. And … inside your home? If your gas furnace is blowing cold air and putting a chill to your Phoenix home, it’s time to contact Integrity AC & Heating LLC. Occasionally the loss of warm air from your gas furnace calls for a major repair, but often it can be a simple 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 regular maintenance performed on your gas furnace lately and you’ve neglected to replace your air filter, both could indicate why your furnace is blowing cool air. A dirty air filter can block air from flowing freely through your furnace. When this happens, the furnace could overheat and cause 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 attributed to something as simple as a pilot light that’s gone out. It’s possible, especially with older models, for a draft to put out 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 battle 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 might be losing a lot of heated air before it even reaches the vents throughout the home.
