    It will be necessary to attach pressure gauges to the air conditioning system to verify the pressures. If you had to top up the system with refrigerant the system has a leak and the system should be evacuated and the leak repaired.
    There is a commercially available refrigerant that has dye in it. You add it to the system if there is a leak the dye stains the area of the leak possibly enabling the leak to be found.
    If you get a friend to start the engine and turn on and off the air conditioning do you hear the air conditioning compressor cycle on and off?
