As the temps change, the more you feel the cooler air gusting outside. And … right inside your house? If your gas furnace is blowing cold air and putting a chill to your Tucson home, it’s time to contact A&M Heating & Cooling LLC. Sometimes the loss of warm air from your gas furnace calls for a big repair, but a lot of time it can be an easy fix. Here are a few of the more common reasons your gas furnace may be blowing cold air instead of making your home warm and cozy.
Your furnace could be overheating
If you haven’t had ongoing maintenance done on your gas furnace for some time and you’ve forgotten to change your air filter, either could indicate why your furnace is blowing cold air. A dirty air filter can block air from flowing freely through your furnace. If that happens, the furnace may overheat and force the burner to shut down.
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, specifically with older furnaces, for a gust of air to extinguish 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 cause challenges 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 fight to stay lit and reduce the warmth inside your house.
Your ducts may not be properly sealed
When ducts are correctly sealed 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.
