As the temps change, the more you feel the cool air blustering outside. And … in your home? If your gas furnace is blowing cold air and adding a chill to your Portland home, it’s time to reach out to Three Rivers Heating & Cooling. Occasionally an absence of warm air from your gas furnace means a large repair, but often it can be an easy fix. Here are some of the main reasons your gas furnace may be blowing cold air instead of warming up your house.
Your furnace may be overheating
If you haven’t had regular maintenance performed on your gas furnace recently and you’ve forgotten to change your air filter, both could indicate why your furnace is blowing colder air. A dirty air filter can stop air from flowing freely through your furnace. If that happens, the furnace could 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 models, for a draft to extinguish a pilot light. Other reasons for an extinguished pilot light are damaged 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 correctly cleaned. A dirty gas burner or flame sensor could cause your furnace to struggle to stay lit and not be able to bring warmth to your home.
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 can get to the vents.
