Why is My Gas Furnace Blowing Cold Air?

As the seasons change, the more you feel the colder air gusting outside. And … inside 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 a lot of time it can be a simple fix. Here are a few of the more common reasons your gas furnace might be blowing cold air instead of warming up your house.

Your furnace may be overheating

If you haven’t had routine maintenance done on your gas furnace recently and you’ve overlooked changing your air filter, either could indicate why your furnace is blowing cool 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 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 properly cleaned. A dirty gas burner or flame sensor could cause your furnace to struggle to stay lit and leave you in the cold.

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 can get to the vents.
