As the weather changes, the more you feel the cool air gusting outside. And … right inside your house? If your gas furnace is blowing cold air and giving a chill to your Rockford home, it’s time to call Temperature Doctors Heating & Cooling, Inc. Sometimes a lack of warm air from your gas furnace calls for a big repair, but often it can be a small fix. Here are a few of the more common reasons your gas furnace could be blowing cold air instead of keeping your home toasty.
Your furnace could be overheating
If you haven’t had ongoing maintenance performed on your gas furnace lately and you’ve neglected to replace your air filter, both could signal why your furnace is blowing cold air. A dirty air filter can block air from flowing freely through your furnace. When this happens, the furnace may 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 credited 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 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 battle to stay lit and leave you in the cold.
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.
