Why is My Gas Furnace Blowing Cold Air?

November 13, 2018

As the temps change, the more you feel the cool air blowing outside. And … in your home? If your gas furnace is blowing cold air and adding a chill to your West Valley City home, it’s time to contact Select Comfort Systems Heating & Air Conditioning. Sometimes an absence of warm air from your gas furnace results in a major repair, but many times 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 performed on your gas furnace recently and you’ve neglected to replace your air filter, each 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 that happens, the furnace could 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 furnaces, for a gust of air to put out a pilot light. Other reasons for an extinguished pilot light are defective gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can mean challenges 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 struggle to stay lit and leave you in the cold.

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 even reaches the vents throughout the home.
