I am trying to determine is American Standard and Trane are the same. The Trane dealer is telling me that they come off the same assembly line and just have differnt outside looks. Looking at the info that I have the inside parts of the XL19i and the Allegiance 18 they look alike. (the compressor picture is the same down to the light refelection).
So, if they are the same why does Consumer Reports have differnt repair ratins for them (American Standard the lowest and Trane 3rd) and why does ACE (www.aceee.org) list American Standard above Trane?
