Why is My Gas Furnace Blowing Cold Air?

Heating

As the seasons change, the more you feel the cooler air blowing outside. And … right inside your house? If your gas furnace is blowing cold air and adding a chill to your Marietta home, it’s time to contact Boyles Mechanical LLC. Once in a while an absence of warm air from your gas furnace means a big repair, but a lot of time it can be a small fix. Here are a few of the more common reasons your gas furnace might be blowing cold air instead of making your home warm and cozy.

Your furnace may be overheating

If you haven’t had ongoing maintenance completed on your gas furnace lately and you’ve overlooked changing your air filter, each could signal 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 shut down its burner.

Your pilot light may have gone out

Sometimes 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, specifically 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 result in problems 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 not be able to bring warmth to your home.

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 ever reaches your vents.
