Why is My Gas Furnace Blowing Cold Air?

As the weather changes, the more you feel the cooler air blowing outside. And … inside your home? If your gas furnace is blowing cold air and giving a chill to your Alliance home, it’s time to call Jack's Refrigeration Heating and Cooling. Sometimes a lack of warm air from your gas furnace results in a major repair, but many times it can be a small fix. Here are several reasons your gas furnace could be blowing cold air instead of warming up your house.

Your furnace might be overheating

If you haven’t had regular maintenance done on your gas furnace lately and you’ve neglected to replace your air filter, either could indicate why your furnace is blowing colder air. A dirty air filter can stop 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

Sometimes 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 systems, for a breeze to extinguish a pilot light. Other factors when it comes to an extinguished pilot light are defective gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can cause challenges 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

When ducts are correctly sealed 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.
