My Furnace Keeps Running! What Do I Do?

Three Things To Check If This Happens To You

You want your furnace to keep your home warm. That’s a simple request, right?

But a furnace that keeps running after you’ve gotten your home warm is a slight problem.

Your home could get too warm, to the point where everyone is uncomfortable. Your furnace will be wasting energy, subsequently driving up your heating costs. And there will be more wear and tear on your furnace, which can lead to future breakdowns and expensive repairs.

If this is happening in your home, it’s time to do some detective work. These troubleshoots may help you solve the problem without a service call. But if you do need one, get in touch with us and we’ll get to you as soon as possible.

Check The Thermostat

Look at the temperature you set on it. If it’s set in the upper 70s or into the 80s, your furnace is going to run for a much longer time to reach and sustain those temperatures.

The U.S. Department of Energy recommends setting your thermostat at 68˚ Fahrenheit when you’re at home. That temperature keeps your home comfortable, but allows for better energy efficiency, saving you money on heating costs.

Check The Air Filter

When was the last time you changed your air filter? If it’s been more than a month or if you can’t remember, check it now. A clogged air filter reduces the air flow through your home’s heating system. That means heated air isn’t getting into your living spaces, forcing your furnace to run longer and cycle on more frequently. Check the air filter once a month, and more often if you have pets or someone in your home has a respiratory condition, changing dirty filters as needed.

Check The Blower Motor

Feel the air coming out of the vents. If it’s warm, both the furnace and blower are running. If it’s cool or cold, only the blower is running. If it’s just the blower, check to see if your thermostat is set to “on” and not “auto.” If that’s the case, switch it to “auto” and see if the problem clears up.

If nothing changes after switching from “on” to “auto,” inspect the thermostat more closely. There may be a wiring problem or worn batteries. If changing the batteries doesn’t work, you will likely need a new thermostat.
