Hey Rip , to hell with Carrier and other packaged systems. We don't do residential normally, but considering your OCD and lust for high quality gear, how would you like our firm to set you up with a nice central chilled water plant? With a carpeted mechanical room of course. We can also do a small steam plant (with cogeneration of course) and maybe thermal energy storage. When the russkies drop the big one you will be sitting pretty and selling heating cooling to the whole neighborhood. We can even give you a plant management system that you can access from your PC or wireless handheld. How about it?
