Why is My Gas Furnace Blowing Cold Air?

November 13, 2018

As the temps change, the more you feel the colder air blowing outside. And … right inside your house? If your gas furnace is blowing cold air and putting a chill to your Long Beach home, it’s time to contact YES R&M Inc.. Once in a while a lack of warm air from your gas furnace means a major repair, but many times it can be a simple fix. Here are some of the main reasons your gas furnace could be blowing cold air instead of keeping your home toasty.

Your furnace may be overheating

If you haven’t had regular maintenance performed on your gas furnace for some time and you’ve overlooked changing your air filter, either could signal why your furnace is blowing colder air. A dirty air filter can stop air from flowing freely through your furnace. When this happens, the furnace could overheat and force 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, especially with older models, for a breeze to smother a pilot light. Other causes of an extinguished pilot light are damaged 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 properly 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 could be losing a lot of heated air before it even reaches the vents throughout the home.
