What does "mini split" mean?
Does mini refer to capacity, the physical size of the indoor or outdoor heat exchangers or something else?
Does split mean that the 2 heat exchangers are in different places as contrasted to a window unit that's all in one box? Does it mean that it's a multi-zone system? Or something else?
So...what distinguishes a mini split from conventional central air? I have a Fujitsu Halcyon AC/heat pump here that is using 2 "concealed ceiling" heat exchangers which are just conventional ducted fan coils controlled by separate t'stats. Is this different than a non mini split?
