Why is My Gas Furnace Blowing Cold Air?

Heating

As the temps change, the more you feel the cool air blustering outside. And … inside your home? If your gas furnace is blowing cold air and putting a chill to your Phoenix home, it’s time to contact Dial One Mears Air Conditioning & Heating Inc. Once in a while a lack of warm air from your gas furnace results in a big repair, but many times 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 regular maintenance done on your gas furnace recently and you’ve forgotten to change 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 that happens, the furnace may 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 models, for a breeze 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 result in problems 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 reduce the warmth inside your house.

Your ducts may not be properly sealed

If your ducts aren’t properly 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.
