I come across many leaking York aluminum coils. You know the low line guardian/York units they leak at the copper connections... I tell the customers they are non repairable unless replaced. Usually units are not in great shape and do not recommend repacement of the coil, also the coils. So at the end of the day I am the bad guy for telling the customer what they don't want to hear, bad news replace whole unit. Who else has these issues with the customers blaming you for something that you've never touched or even serviced aver.
