Modern A/C systems will cycle in order to prevent the evaporator from freezing up. Moisture in the air condenses on the cold evaporator and if the A/C runs unlimited, this moisture will freeze on the evaporator and eventually block the air flow through the it. So todays A/C system monitor the temperature of the evaporator and will turn the A/C off periodically to prevent freeze up. In addition, most A/C systems will disengage at wide open throttle in order ensure all available horsepower is available to drive the vehicle. Modern A/C systems require from 2-5 hp to operate.

Why does the ac compressor kick on and off?
The AC Compressor will kick on and off to maintain approx 32 psi on the suction side of your Air Conditioning system. This creates a continuous cycle of Freon which will change from a Liquid on the suction side into a Gas on the Pressure side. During this exchange from Liquid to Gas cold air is created to cool your space.

You probably need a new air filter for your a/c The clicking is probably caused by the clutch on the compressor. If the Ac isn't charged enough it could cause this to kick the compressor off and on. You compressor could also be bad. You werent real clear what the problem was. Hope this helps.
