Signs Your Furnace Is Short Cycling



If your furnace is on and off repeatedly, this is known as short cycling, and it’s very dangerous. A unit that turns on and off, generating heat then shutting down, over and over again, may break down quickly. It may also need frequent repairs and could even have a decreased life span. Worse, short cycling can cause your energy bills to spike during cold weather. Here are the top signs that your furnace may be short cycling.


Thermostat Is Malfunctioning

If your thermostat is malfunctioning, it will give incorrect readings to your furnace. If your thermostat seems poorly calibrated, or like it doesn’t respond to your commands, a technician may need to repair it. When a thermostat sends incorrect signals to the furnace, the unit may turn on and off quickly, confused by the signals it’s receiving. This is known as short cycling.


The Area Around the Furnace Is Hot

A furnace generates heat, so warmth around the unit is to be expected, but if it’s unusually hot near your furnace, the unit may be overheating. Overheating for any reason, like clogged filters or buildup inside the machine, can make a furnace short cycle.


Short Bursts of Heat

You may not notice the furnace itself turning on and off repeatedly, but you may be able to tell if it’s releasing short bursts of warm air indoors. Do your vents seem to expel short-lived gusts of warm air, shut off quickly, and repeat multiple times? The furnace should release a steady stream of heat, otherwise it may be short cycling.
