Not sure I understand your question. Please clarify.

If you are having to add refrigerant for the system to cool correctly, there is a leak, no ifs ands or buts about it. Leaks can be extremely hard to locate. It may take hiring in a pro with the correct equiptment and knowledge to locate and fix the leak. Simply adding refrigerant every now and again is not only expensive, but against the law. Time to get the professionals in there.
