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 giving a chill to your Paso Robles home, it’s time to reach out to Paso Robles Heating and Air. Occasionally the loss of warm air from your gas furnace results in a large repair, but often it can be a small fix. Here are some of the main reasons your gas furnace might be blowing cold air instead of making your home warm and cozy.

Your furnace could be overheating

If you haven’t had regular maintenance completed on your gas furnace recently and you’ve forgotten to change your air filter, each could signal why your furnace is blowing cold air. A dirty air filter can stop air from flowing freely through your furnace. When this happens, the furnace could overheat and cause the burner to shut down.

Your pilot light may have gone out

It could be that a lack of warm air from your gas furnace can be related to something as simple as a pilot light that’s gone out. It’s possible, particularly 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 result in issues for your gas furnace, so can other furnace components if they aren’t appropriately 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

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 can get to the vents.
