Why is My Gas Furnace Blowing Cold Air?

Heating

As the weather changes, the more you feel the cooler air gusting outside. And … right inside your house? If your gas furnace is blowing cold air and giving a chill to your East Bernard home, it’s time to reach out to E B Air Conditioning & Heating Service. Once in a while the loss of warm air from your gas furnace means a major repair, but often it can be a small fix. Here are some of the main reasons your gas furnace may be blowing cold air instead of making your home warm and cozy.

Your furnace could be overheating

If you haven’t had ongoing maintenance performed on your gas furnace lately and you’ve overlooked changing your air filter, either could indicate why your furnace is blowing colder air. A dirty air filter can prevent air from flowing freely through your furnace. If this occurs, 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 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 defective gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can mean challenges 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 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 even reaches the vents throughout the home.
