Why is My Gas Furnace Blowing Cold Air?

November 13, 2018

As the seasons change, the more you feel the cooler air gusting outside. And … in your home? If your gas furnace is blowing cold air and putting a chill to your Paxinos home, it’s time to contact LTS Plumbing & Heating Inc.. Occasionally the loss of warm air from your gas furnace results in a large repair, but a lot of time it can be a simple fix. Here are a few of the more common reasons your gas furnace may be blowing cold air instead of keeping your home toasty.

Your furnace might be overheating

If you haven’t had ongoing maintenance performed on your gas furnace recently and you’ve neglected to replace your air filter, each 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 this occurs, 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, particularly with older systems, for a gust of air to put out a pilot light. Other reasons for 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 appropriately 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 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.
