Why is My Gas Furnace Blowing Cold Air?

Heating

As the temps change, the more you feel the cool air gusting outside. And … in your home? If your gas furnace is blowing cold air and putting a chill to your Tomball home, it’s time to reach out to Premium Air Services LLC. Occasionally an absence of warm air from your gas furnace calls for a large repair, but often 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 keeping your home toasty.

Your furnace might be overheating

If you haven’t had regular maintenance done on your gas furnace lately and you’ve forgotten to change your air filter, each could indicate why your furnace is blowing colder air. A dirty air filter can prevent air from flowing freely through your furnace. When this happens, the furnace may overheat and force the burner to shut down.

Your pilot light may have gone out

Sometimes 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 systems, for a breeze 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 properly 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.
