To properly recharge the leak has to be fixed, the system dried out evacuated properly, a proper charging valve installed (a schrader valve welded into the line,) and then a proper charge with the proper amount of oil for the system. On small self contained systems the amount of charge is critical and a few ounces under it won't cool and few over it will destroy the compressor. It's really not a DIY project in my opinion.

Moving forward, does anyone know of reliable certified repair persons in the Nashville Tennessee area? Thanks for any help.
