Why is My Gas Furnace Blowing Cold Air?

As the temps change, the more you feel the colder air gusting outside. And … in your home? If your gas furnace is blowing cold air and putting a chill to your Suffolk/Nassau County home, it’s time to contact Airmax Long Island Inc. Occasionally the loss of warm air from your gas furnace means a big repair, but often 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 performed on your gas furnace recently and you’ve overlooked changing your air filter, either could indicate why your furnace is blowing colder air. A dirty air filter can stop air from flowing freely through your furnace. If this occurs, the furnace may 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, particularly with older systems, for a breeze to put out a pilot light. Other factors when it comes to an extinguished pilot light are faulty gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can mean 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 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 can get to the vents.
