Why is My Gas Furnace Blowing Cold Air?

As the seasons change, the more you feel the colder air gusting outside. And … in your home? If your gas furnace is blowing cold air and putting a chill to your Dallas home, it’s time to contact Tri County Air Care LLC. Occasionally a lack of warm air from your gas furnace calls for a large repair, but many times it can be an easy fix. Here are a few of the more common reasons your gas furnace may be blowing cold air instead of warming up your house.

Your furnace could be overheating

If you haven’t had regular maintenance completed on your gas furnace recently and you’ve forgotten to change your air filter, both could signal why your furnace is blowing cold 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 could be that a lack of warm air from your gas furnace can be attributed to something as simple as a pilot light that’s gone out. It’s possible, specifically with older furnaces, for a gust of air to extinguish a pilot light. Other factors when it comes to an extinguished pilot light are damaged gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can cause 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 fight 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 may be losing a lot of heated air before it ever reaches your vents.
