Keycity- When I started scrapping I called the local yards here and asked about removal of refrigerants. I got the answer that it did not need to be removed for them to accept a/c, refrigerators etc. then I discovered why. They had all the appliances with refrigerants in a separate area with one of their guys doing the removal. Since that time I have become much wiser about the parts and metals that can be recovered after evacuacting the system. I also have a deal with a friend to recover all refrigerants and we split 70/30 in his favor when he sells it. I never have been asked to sign anything regarding where it was obtained and who evacuated the refrigerants.
