How far away can the condenser be located from the air handler? Does it have to be outside or can it work in a garage? Also, how do I determine the size of system I need? Biggest problem with our current nat gas furnace, which isn't a fuel problem per se, is that it isn't zoned (which I can alleviate somewhat with the ecobee and its remote temp sensors) so I am considering installing mini-splits in the bedrooms and downstairs room and having the main furnace for heating the living room and other areas as needed but I'd also like to move the main furnace off nat gas as well at some point if possible but I don't want a big condenser taking up space in the rear patio which is potentially where I could see your unit come in.
Condenser can be typically ~25ft from the air handler. It would have to be outside, otherwise it would act as a refrigerator for the garage, and tank the efficiency of the system. System size - we're working on an online tool to get you close to the right size. In the current flow you preorder and a contractor will prepare the final quote and system sizing (we give them a web app to turn a utility bill into a heat pump size).
