Yes, short cycling is harmful in many ways. Your furnace, thermostat, or otherwise may “think” that it has met 70 degrees before it actually has, and another request may occur where the thermostat is telling the furnace, “hotter, please” which causes frequent on and off cycling of the furnace. Your thermostat will tell your furnace to turn on and produce heat until it gets to the threshold of 70 or above. Let’s say you set your thermostat at 70 degrees, and it’s currently 65 in your home. 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.

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. I haven’t changed my temperature in my house, but my AC or furnace is still trying to turn on and off to fulfil a demand I haven’t made.My AC or furnace seems to be running more frequently than usual.My AC or furnace keeps turning on and off repeatedly.Short Cycling… Have you heard this term before? Your air conditioner or even furnace can suffer from a short cycling issue, but it is something that can be fixed, and it won’t cost you an arm and a leg.
