Are a few of you blokes heat pump experts? I'm attracted to Mitsubishi's M-series of inverter-driven split ductless and ducted "comfort" systems.
I'm thinking of a small one for the upstairs master bedroom, etc., and maybe a bigger one for the living room. We already have a whole-house HVAC system, but it has no zone capability, and it'd be nice to have a cool bedroom on those hot August nights.
