You need to put a UV dye in the system, run the A/C a lot to let it circulate as much as it can and then use a UV light and safety glasses that are designed for finding leaks to locate where it is leaking from.

Do as suggested and i would also use a gas sniffer if you cant see any leaks, and check the vents for refregrant as you may have a leak in the evaporator and you will not see this with the UV system.
