Why is My Gas Furnace Blowing Cold Air?

As the seasons change, the more you feel the cooler air blowing outside. And … right inside your house? If your gas furnace is blowing cold air and adding a chill to your Royse City home, it’s time to reach out to B&W Services. Once in a while a lack of warm air from your gas furnace means a major 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 warming up your house.

Your furnace could be overheating

If you haven’t had ongoing maintenance performed on your gas furnace for some time and you’ve forgotten to change your air filter, each could indicate why your furnace is blowing cool air. A dirty air filter can stop air from flowing freely through your furnace. If this occurs, the furnace may 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 attributed to something as simple as a pilot light that’s gone out. It’s possible, especially with older models, for a draft 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 challenges for your gas furnace, so can other furnace components if they aren’t appropriately 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 even reaches the vents throughout the home.
