^^ This unless you have the knowledge and means of repairing an AC system. I'm learning as I go with my Bronco 2 and taking my time reading a lot and re-reading. Very interesting and I read somewhere that you think you know about AC but you don't. Its very true. Tons of great information in the tech section of this forum on the AC system, how it works, and how to repair it very carefully and how to do it the right way. We all see those recharge cans at the stores with the little dial gauge...those things are garbage and spell disaster to your AC system as you are only getting 1/2 the information on that one gauge, not to mention most have leak sealants which most likely will plug up your orifice tube and everything else but not the real leak. Best to do a full system evacuation and start at the beginning in an unknown system or any system for that matter.
The PO of my Bronco 2 did tell me the compressor failed and was replaced, but the system was never evacuated, flushed, and repaired beyond the compressor replacement.
