Furnace damage —Turning on and off frequently puts stress on parts in your furnace, causing them to wear out faster. And furnace repairs can get expensive, so this will end up costing you a lot of money down the road. When a system short cycles, it can kick on and off repeatedly, sometimes multiple times per hour or in extreme circumstances, multiple times per minute. This happens when your system is asked to produce a certain temperature (whether hot or cold), and the requirements have not been met, but your system turns off as if it “thinks” it met the requirement. A furnace that starts then stops is a common issue also known as short cycling. The furnace starts to heat the home, but turns off again quickly after only a short amount of time has passed.

On average, a furnace will cycle every 10 to 20 minutes. The amount of time between cycles is dependent on a number of factors, including the outside air temperature and the temperature at which the thermostat is set.
