Answers:
In order to work with any type of refrigerant the EPA requires you to be licensed. You must also be licensed to purchase refrigerant. You are not allowed to charge air conditioners of any type without a license. Without the proper training you could damage your unit and even cause injury to yourself or others. You are better off calling a qualified, trained and licensed professional to do such work.
