You take it to a mechanic certified to work on ac systems, and who is familiar with the severe safety issues of working with refrigerants. He will also have reclaiming, recycling, and charging equipment. If you put in too much refrigerant, you can destroy the compressor. Also, any time the system is discharged and opened, the receiver / drier should be replaced. The system must be pumped into a vacuum before the measured amount of refrigerant is pumped in. Failure to do this will leave moisture in the system. On older vehicles with R-12, water and refrigerant mix to form hydrochloric acid. That does wonders for the metal parts!
As part of the performance test, he will do a leak check with specialized electronic equipment.
