As the temps change, the more you feel the cool air blustering outside. And … right inside your house? If your gas furnace is blowing cold air and giving a chill to your New Castle home, it’s time to reach out to Central Heating & Plumbing. Once in a while the loss of warm air from your gas furnace calls for a large repair, but often it can be a small fix. Here are a few of the more common reasons your gas furnace may be blowing cold air instead of keeping your home toasty.
Your furnace could be overheating
If you haven’t had ongoing maintenance completed on your gas furnace recently and you’ve neglected to replace your air filter, both could indicate why your furnace is blowing cold air. A dirty air filter can prevent air from flowing freely through your furnace. If that happens, the furnace may overheat and shut down its burner.
Your pilot light may have gone out
It’s probable 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, specifically with older furnaces, for a gust of air to smother a pilot light. Other factors when it comes to an extinguished pilot light are faulty gas valves or a faulty thermocouple.
Your furnace is dirty
Just as a dirty air filter can cause issues 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 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 might be losing a lot of heated air before it ever reaches your vents.
