As the temps change, the more you feel the cooler air blustering outside. And … right inside your house? If your gas furnace is blowing cold air and giving a chill to your Pacheco home, it’s time to reach out to Clean Air HVAC. Sometimes an absence of warm air from your gas furnace calls for a large repair, but many times 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 may be overheating
If you haven’t had regular maintenance completed on your gas furnace lately and you’ve forgotten to change your air filter, each could indicate why your furnace is blowing cool 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 attributed to something as simple as a pilot light that’s gone out. It’s possible, especially with older systems, 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 correctly cleaned. A dirty gas burner or flame sensor could cause your furnace to battle 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 might be losing a lot of heated air before it even reaches the vents throughout the home.
