In my opinion, the best way to start would be to locate and identify the leak. If your A/C system has no refrigerant in it, it has leaked out somewhere. There is also a lubicant in the system called PAG Oil. If the clutch on the compressor is slipping, it's a possibility that the front compressor seal has been leaking and the PAG Oil has contaminated the compressor clutch. The 134a refrigerant is ozone-friendly and resonably inexpensive, so if you add a can and use it to check for leaks; you may be able to visually find the leak if it is a large one. A fill-kit can be purchased at any good auto-parts store for a minimal amount of money. And if it is indeed the compressor seal, a compressor rebuilt kit is probably available. Compressor replacement may not be necessary.
