Why is My Gas Furnace Blowing Cold Air?

Heating

As the seasons change, the more you feel the cooler air gusting outside. And … right inside your house? If your gas furnace is blowing cold air and adding 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 results in a big repair, but many times 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 ongoing maintenance done on your gas furnace lately and you’ve neglected to replace your air filter, each could be the reason why your furnace is blowing cool air. A dirty air filter can stop air from flowing freely through your furnace. If that happens, the furnace might overheat and force the burner to shut down.

Your pilot light may have gone out

It could be that a lack of warm air from your gas furnace can be credited to something as simple as a pilot light that’s gone out. It’s possible, especially with older systems, for a gust of air to put out a pilot light. Other causes of 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 correctly cleaned. A dirty gas burner or flame sensor could cause your furnace to battle to stay lit and leave you in the cold.

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 can get to the vents.
