If the furnace in your Palm City, FL, home is always running, you may wonder why. Here are four reasons your furnace is constantly running and what to do about them.

Disabled the Fan’s Auto Setting

Sometimes, your system may seem like it’s running when it’s really just the blower fan that won’t turn off. This might happen if you’ve inadvertently set the fan control to “on” instead of “auto” on your thermostat. In that case, changing the fan control back to “auto” should set things right.

Clogged Air Filter

When your furnace heats your home, it works hard to push heated air through its ducts into every room. If your furnace’s air filter gets clogged, it won’t be able to do that and will run all the time. Cleaning or changing your furnace’s air filter should solve the problem.

Thermostat is Malfunctioning

Your furnace depends on your thermostat to tell it when to turn on and off. So, if your thermostat isn’t working right, it could be telling your system to stay on when it shouldn’t. To resolve the issue, you’ll want an expert heating service technician to take a look and make appropriate repairs.

Faulty Limit Switch

Furnaces have a device called a limit switch that physically turns it on and off when required. If the limit switch on your furnace isn’t working, it could fail to turn off your system when it should. In that case, having a heating service technician replace it should return your furnace to normal operation.

Of course, you don’t have to wait for your system to misbehave before you give it your attention. Instead, you should make it a point to schedule regular furnace service appointments to keep it working well.
