As the temps change, the more you feel the cool air blowing outside. And … in your home? If your gas furnace is blowing cold air and giving a chill to your Libertyville home, it’s time to reach out to TopTec Heating, Cooling, Plumbing & Electrical. Sometimes a lack of warm air from your gas furnace results in a big repair, but often it can be a simple fix. Here are several reasons your gas furnace may be blowing cold air instead of warming up your house.
Your furnace may be overheating
If you haven’t had regular maintenance done on your gas furnace lately 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 might overheat and shut down its burner.
Your pilot light may have gone out
It could be that 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 put out a pilot light. Other causes of an extinguished pilot light are faulty gas valves or a faulty thermocouple.
Your furnace is dirty
Just as a dirty air filter can result in problems 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 struggle 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 might be losing a lot of heated air before it ever reaches your vents.
