Why Your Furnace Keeps Shutting Down Early

Monday, February 6th, 2023
frustrated-person-asking-why

Your furnace is designed to start up when the thermostat registers that your home has reached a specific lower temperature, run until it reaches a set higher temperature, and shut off. These cycles should last 15 or even 20 minutes and then repeat. Sometimes a furnace begins a heating cycle, shuts down too soon, and tries again just a few minutes later. This is called short cycling, and indicates that there’s a problem with your heater.

Short cycling has a variety of possible causes, and you should get to the bottom of it promptly, because it can cause additional problems with your heater. What could possibly be wrong? We’re so glad you asked.

We made it through a very cold February, and now many of us are hoping we’ll have an easy shot right to spring. It might happen.

During our mild winter months when you run the furnace to keep your household warm, you’ll become used to a standard pattern for how the HVAC system turns on and off. You’ll hear the blower fan come on, then the furnace burners ignite, and the rush of heated air pushed through the ductwork. After fifteen minutes or more, the furnace will then start cycling down, turning off the burners and eventually the fan. When the temperature begins to fall below the setting on the thermostat, the HVAC system will begin another heating cycle.

This is the normal behavior you’re used to from the furnace and probably don’t pay much attention to it. But if the furnace breaks this pattern and begins to turn on and off with greater frequency, you may notice. And then you may wonder: is this a problem?
