Aircon is not an easy thing to repair.

First have you been into frontal collision before (however light it is, it is easy to cause aircon gas leak because certain piping joint has been slightly bend). Usually mechanic will use soap water with bubbles to wipe on those pipe reachable by hand. (Good luck to those unreachable ones).

Second, is your cooling coil. Is it clogged or rusted and leak?

Third is your compressor leaking? or compressor not compressing the gas (eg. the magnet clutch part not functioning)?

Condensor dirty?

...


If you want total fix in one short, the only way to do it is replace every damn thing that is part of the gas travel path.
