First things first, inspect condenser for signs of damage, may have a hole in it from road debris. Inspect all components for signs of leaks, newer units come pre installed with leak detection dye which will show up with a black light. After that and still unable to locate leak take it to an ac shop and have them put a partial charge in system and check for leaks with a leak detector. Spending a little time and money on diagnosis and not somebodys word on it could save you lots of money on a compressor you didnt need
