Why is My Gas Furnace Blowing Cold Air?

November 13, 2018

As the seasons change, the more you feel the cool air gusting outside. And … in your home? If your gas furnace is blowing cold air and adding a chill to your Tomball home, it’s time to contact Premium Air Services LLC. Occasionally the loss of warm air from your gas furnace results in a large repair, but a lot of time it can be an easy fix. Here are several reasons your gas furnace might be blowing cold air instead of making your home warm and cozy.

Your furnace might be overheating

If you haven’t had ongoing maintenance completed on your gas furnace for some time and you’ve forgotten to change your air filter, each could signal why your furnace is blowing cool air. A dirty air filter can prevent air from flowing freely through your furnace. When this happens, the furnace may overheat and cause 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 draft to put out a pilot light. Other reasons for 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 correctly cleaned. A dirty gas burner or flame sensor could cause your furnace to fight to stay lit and reduce the warmth inside your house.

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 even reaches the vents throughout the home.
