Why Is a Short Cycling Air Conditioner a Problem?

“Short cycling” is a term used to describe when an air conditioner turns on and off rapidly throughout the day. It could mean a system that shuts off before it has finished cooling your house, only to turn on again a few minutes later. It could also refer to a system that cools the air too quickly, turning off only to turn on again too soon. In either case, it spells trouble for your air conditioner. With another hot and humid summer on its way for residents of Round Rock, TX, trouble is the last thing you need. Why is a short cycling air conditioner a problem? Read on for the answers.


Air conditioners spend far more energy to turn on and off than they do simply running. Furthermore, they often engender a great deal of wear and tear in the process, as moving parts create friction when they startup. Not only does short cycling thus increase the risk of a major repair issue (and shorten the overall life of your system), but it will raise your monthly energy costs right at the time when they tend to spike anyway.


Short cycling can be caused by a number of different mechanical issues, including a lack of refrigerant and a malfunction in the converter array. It can also be more systematic, created because your air conditioner is too powerful for the space it needs to cool. If your air conditioner has exhibited short cycling since its installation, this is probably the case, and you might need to think about replacing it again (especially if it’s still under warranty). Otherwise, a repair session can usually correct the problem and keep those short cycling problems under wraps.
