Why is My Gas Furnace Blowing Cold Air?

November 13, 2018

As the weather changes, the more you feel the colder air blowing outside. And … in your home? If your gas furnace is blowing cold air and putting a chill to your Alice home, it’s time to reach out to Rescue Heating & Air . Once in a while the loss of warm air from your gas furnace means a big repair, but a lot of time it can be a simple fix. Here are some of the main reasons your gas furnace may be blowing cold air instead of keeping your home toasty.

Your furnace may be overheating

If you haven’t had ongoing maintenance done on your gas furnace for some time and you’ve forgotten to change your air filter, each could be the reason why your furnace is blowing cool air. A dirty air filter can stop air from flowing freely through your furnace. When this happens, the furnace might overheat and cause 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 credited to something as simple as a pilot light that’s gone out. It’s possible, specifically with older models, for a draft to extinguish a pilot light. Other reasons for an extinguished pilot light are faulty gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can cause 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 leave you in the cold.

Your ducts may not be properly sealed

If your ducts aren’t properly sealed 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.
