As the temps change, the more you feel the colder air gusting outside. And … right inside your house? If your gas furnace is blowing cold air and putting a chill to your Dayton home, it’s time to contact Jent Mechanical LLC. Once in a while the loss of warm air from your gas furnace calls for a major repair, but often it can be a simple fix. Here are some of the main reasons your gas furnace may be blowing cold air instead of warming up your house.
Your furnace might be overheating
If you haven’t had regular maintenance done on your gas furnace lately and you’ve neglected to replace your air filter, either could indicate why your furnace is blowing cold air. A dirty air filter can block 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
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 gust of air to smother a pilot light. Other factors when it comes to an extinguished pilot light are damaged 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 struggle to stay lit and leave you in the cold.
Your ducts may not be properly sealed
If your ducts aren’t properly 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.
