Why is My Gas Furnace Blowing Cold Air?

November 13, 2018

As the temps change, the more you feel the colder air blustering outside. And … in your home? If your gas furnace is blowing cold air and putting a chill to your Ronkonkoma home, it’s time to reach out to Cool Power LLC . Sometimes a lack of warm air from your gas furnace means a large repair, but often it can be a simple fix. Here are several reasons your gas furnace could be blowing cold air instead of making your home warm and cozy.

Your furnace could be overheating

If you haven’t had routine maintenance completed on your gas furnace recently and you’ve forgotten to change your air filter, either could indicate why your furnace is blowing cool air. A dirty air filter can block air from flowing freely through your furnace. If that happens, the furnace could overheat and shut down its burner.

Your pilot light may have gone out

It could be that 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 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 battle to stay lit and reduce the warmth inside your house.

Your ducts may not be properly sealed

When ducts are correctly sealed or if they have any cracks or holes in them, you may be losing a lot of heated air before it even reaches the vents throughout the home.
