I aquired some home ac unit parts and i was wondering if anyone could help. I think they are the compressors off of the unit. Its about a foot and a half tall and is egg shaped. It weighs about 50 lbs each or more and had copper pipe going into it. Has anyone ever cut one of these open? Any copper inside of them or is it just the piping that is copper? Thanks all, i just dont know if it would be a waste of time opening it or do you guys just sell them outright?
