Why is My Gas Furnace Blowing Cold Air?

As the temps change, the more you feel the colder air blowing outside. And … inside your home? If your gas furnace is blowing cold air and giving 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 a simple fix. Here are a few of the more common reasons your gas furnace might be blowing cold air instead of making your home warm and cozy.

Your furnace may be overheating

If you haven’t had regular maintenance completed on your gas furnace recently and you’ve overlooked changing your air filter, each could indicate why your furnace is blowing cold air. A dirty air filter can block air from flowing freely through your furnace. If this occurs, the furnace might overheat and shut down its burner.

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 systems, 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 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

If your ducts aren’t sealed properly or if they have any cracks or holes in them, you could be losing a lot of heated air before it even reaches the vents throughout the home.
