Why is My Gas Furnace Blowing Cold Air?

November 13, 2018

As the seasons change, the more you feel the cool air gusting outside. And … right inside your house? If your gas furnace is blowing cold air and giving a chill to your Cottonwood home, it’s time to reach out to Connolly Electric & Mechanical. Sometimes an absence of warm air from your gas furnace calls for a major repair, but many times it can be an easy fix. Here are a few of the more common reasons your gas furnace may 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 overlooked changing your air filter, either could be the reason why your furnace is blowing cold air. A dirty air filter can prevent air from flowing freely through your furnace. If this occurs, the furnace might overheat and cause the burner to shut down.

Your pilot light may have gone out

Sometimes 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, specifically with older furnaces, for a gust of air to put out a pilot light. Other causes of 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 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 battle 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 might be losing a lot of heated air before it can get to the vents.
