Why is My Gas Furnace Blowing Cold Air?

Heating

As the weather changes, the more you feel the cooler air blowing outside. And … inside your home? If your gas furnace is blowing cold air and giving a chill to your Metro Atlanta home, it’s time to contact ACS Inc. Sometimes a lack of warm air from your gas furnace results in 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 warming up your house.

Your furnace might 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, both could be the reason why your furnace is blowing colder air. A dirty air filter can prevent 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’s probable 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 furnaces, for a gust of air to extinguish 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 problems for your gas furnace, so can other furnace components if they aren’t appropriately cleaned. A dirty gas burner or flame sensor could cause your furnace to struggle 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 sealed properly or if they have any cracks or holes in them, you could be losing a lot of heated air before it ever reaches your vents.
