Why is My Gas Furnace Blowing Cold Air?

Heating

As the seasons change, the more you feel the cooler air blustering outside. And … inside your home? If your gas furnace is blowing cold air and adding a chill to your Bossier City home, it’s time to contact Central Aire Heating & A/C Inc. Sometimes the loss of warm air from your gas furnace means a major repair, but often it can be an easy fix. Here are a few of the more common reasons your gas furnace might be blowing cold air instead of keeping your home toasty.

Your furnace might be overheating

If you haven’t had ongoing maintenance done on your gas furnace for some time and you’ve neglected to replace your air filter, both could signal why your furnace is blowing cool air. A dirty air filter can block air from flowing freely through your furnace. If that happens, the furnace could 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, especially with older models, for a draft to smother 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 cause 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 fight to stay lit and reduce the warmth inside your house.

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 can get to the vents.
