John The A/C system needs to move lots of freon to carry away the heat. If there is a filter dryer it may be partially clogged. If there is an in line orifice as is currently used by many manufacturers, it may have the same problem. Someone else in the club may know the exact details of your system. If clogging is the problem then replacing the offending component will solve the cooling problem. Perhaps the charge was never correct and even if it was, it would not stay that way long because of the leak. If very cool means the outlet air temperature is in the 40s, your only problem is the leak. To fix the leak will require the system to be opened whether the seal is replaced or compressor swapped. Care must be used when you remove and install the clutch to prevent damage to the compressor. As for the freon, R414A and R414B (Hot Shot) are drop in replacements for R12. R414B is also drop in for R134 systems. Neither require any component or oil changes. Cost is less than $10 per pound but R414A can only be purchased in 25lb. bottles. I believe the Hot Shot can be purchased at auto parts stores in 12 or 14oz cans. I have used R414A in R12 systems for years with excellent results. A/C repair shops will not do this retrofit for fear of legal problems. It is legal for private parties however except possibly in California. If you want more info, contact me.
