Hi, as a mechanical engineer, if they find no leaks that means that they have to check two devices. One is the compressor and they have to repalce it if not working properly under warranty. The other one is the expansion device. Usually a capillary tube before evaporatore that has the task to expand the refrigerant and so the temperature is reduced in the evaporator. Anyway if they uderstand that you are not much aware of ACUs they will only refill with refrigerant. My suggestion is to forced the check the compressor (Inlet and outlet temperature) and the caipllary tube which I belive is the problem.
