You could go that same way with AP Air kits, I just don't do it because most of my customers want to only replace what the have to and don't want to hassle with remembering what the lines go to if they need one in the future.

I'm not particular about the replacement brand as long as its not an A6 reman.  Maybe I shouldn't be so critical of them, those things have brought us lots of work!!!  LOL

Oh yea, AP offers a high efficiency  evaporator and a high output fan.  Put them on with your extra condenser and you've got a meat cooler.
