As the temps change, the more you feel the cool air gusting outside. And … right inside your house? If your gas furnace is blowing cold air and putting a chill to your Pella home, it’s time to call Van Haaften Plumbing & Heating. Occasionally the loss of warm air from your gas furnace results in a large repair, but a lot of time it can be a simple fix. Here are several reasons your gas furnace could be blowing cold air instead of keeping your home toasty.
Your furnace may be overheating
If you haven’t had ongoing maintenance done on your gas furnace recently and you’ve neglected to replace your air filter, both could signal why your furnace is blowing colder air. A dirty air filter can stop air from flowing freely through your furnace. When this happens, the furnace might 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 credited to something as simple as a pilot light that’s gone out. It’s possible, particularly with older models, for a breeze to smother a pilot light. Other factors when it comes to an extinguished pilot light are defective gas valves or a faulty thermocouple.
Your furnace is dirty
Just as a dirty air filter can cause problems 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 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 may be losing a lot of heated air before it can get to the vents.
