Why is My Gas Furnace Blowing Cold Air?

As the temps change, the more you feel the colder air blowing outside. And … in your home? If your gas furnace is blowing cold air and adding a chill to your Kearney home, it’s time to reach out to Thurston Heating & Air Conditioning. Sometimes the loss of warm air from your gas furnace means a big repair, but often it can be an easy fix. Here are a few of the more common reasons your gas furnace might be blowing cold air instead of keeping your home toasty.

Your furnace may be overheating

If you haven’t had routine maintenance done on your gas furnace lately and you’ve forgotten to change your air filter, each could indicate why your furnace is blowing cool air. A dirty air filter can block air from flowing freely through your furnace. When this happens, the furnace might overheat and cause 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, especially with older models, for a draft to put out 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 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 fight to stay lit and reduce the warmth inside your house.

Your ducts may not be properly sealed

If your ducts aren’t sealed properly 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.
