Again, amazing advice. You are an incredible help to this community mytek. I'm going to pickup one of these ac's as the condenser setup is exactly what size I've been wanting, and the rotarys already placed perfectly. I do not have r23 just yet, but I'm also going to get a quote as I think its nearly the perfect autoc gas from most reading. I'll probably turn this ac into a chiller with a 16plate hx, but in the future I'm going to try what you have built, with our style evaporator and flexible line, and also use my lever arm pipe bender to make a tighter almost plateHX sized heat exchanger. I have one last question, do you use a pour-then-expand insulation foam, or a spray foam?
