Why is My Gas Furnace Blowing Cold Air?

November 13, 2018

As the seasons change, the more you feel the cool air blowing outside. And … right inside your house? If your gas furnace is blowing cold air and putting a chill to your Safford home, it’s time to contact B&D Air Conditioning. Sometimes the loss of warm air from your gas furnace results in a big repair, but many times it can be a simple fix. Here are some of the main reasons your gas furnace may be blowing cold air instead of making your home warm and cozy.

Your furnace might be overheating

If you haven’t had routine maintenance completed on your gas furnace recently and you’ve forgotten to change your air filter, each could indicate why your furnace is blowing colder air. A dirty air filter can prevent 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, specifically with older systems, for a breeze to smother a pilot light. Other factors when it comes to an extinguished pilot light are damaged gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can cause 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 fight 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 ever reaches your vents.
