Several conditions cause short cycling, including a faulty or obstructed thermostat, leaking refrigerant, icy coils or an hvac system that is too big for the building in which it. If your air conditioner turns on and off at intervals of less than ten minutes it is probably short cycling and also deserves a service call.
