As the temps change, the more you feel the cool air gusting outside. And … in your home? If your gas furnace is blowing cold air and putting a chill to your Phoenix home, it’s time to contact Dial One Mears Air Conditioning & Heating Inc. Sometimes an absence of warm air from your gas furnace results in a big repair, but many times 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 could be overheating
If you haven’t had regular maintenance performed on your gas furnace for some time and you’ve neglected to replace your air filter, both could signal why your furnace is blowing cool air. A dirty air filter can block air from flowing freely through your furnace. If that happens, the furnace may 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 attributed to something as simple as a pilot light that’s gone out. It’s possible, specifically with older models, for a draft to put out a pilot light. Other factors when it comes to an extinguished pilot light are faulty 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 appropriately cleaned. A dirty gas burner or flame sensor could cause your furnace to battle 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 may be losing a lot of heated air before it ever reaches your vents.
