Why Does My Furnace Keep Turning Off and On?

If your furnace is constantly turning off and on, your local HVAC professionals can determine the cause of this issue to restore comfort for you and your family in Covington, Louisiana.

Dirty Components

While a dirty air filter is one of the most common triggers for short-cycling in furnaces, dirty flame sensors and blocked vents can also cause your furnace to turn on and off repeatedly. Scheduling regular maintenance is one of the best ways to avoid these issues, which can result in much higher energy bills and reduced comfort inside your home. During your fall maintenance visit, our technician will typically replace dirty air filters and identify other issues that could cause short cycling for your home HVAC system.

A Malfunctioning Thermostat

A failing thermostat can send signals to your HVAC system that will cause it to cycle on and off rapidly. Fortunately, short cycling caused by a malfunctioning thermostat can easily be resolved by replacing the thermostat. Your heating and cooling technician can recommend and install a new smart thermostat that will make it much easier to manage indoor temperatures while keeping your utility bills lower all year round.
