How do I know if my AC is short cycling?

Short-cycling is a term for when an air conditioner shuts down its cooling cycle prematurely, only to start back up again a short time later. If you have noticed that your air conditioner’s compressor is turning on and off rapidly, it is probably short-cycling and you need to have it repaired.
