Why is My Gas Furnace Blowing Cold Air?

As the temps change, the more you feel the cool air gusting outside. And … in your home? If your gas furnace is blowing cold air and giving a chill to your Westminster home, it’s time to reach out to True Heating & Cooling. Occasionally a lack of warm air from your gas furnace means a major repair, but many times it can be an easy fix. Here are a few of the more common reasons your gas furnace could be blowing cold air instead of making your home warm and cozy.

Your furnace may be overheating

If you haven’t had ongoing maintenance done on your gas furnace recently and you’ve forgotten to change your air filter, either could be the reason 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 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 attributed to something as simple as a pilot light that’s gone out. It’s possible, especially with older systems, for a breeze to extinguish a pilot light. Other reasons for an extinguished pilot light are faulty gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can result in issues 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 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 could be losing a lot of heated air before it can get to the vents.
