I was told that Mitsubishi makes conventional, ducted AC units (not heat pumps). In addition I was told that it uses an inverter drive compressor (DC, true variable speed). I cannot find these units online. Can anyone confirm or deny what I was told? If they exist please provide some part numbers, model numbers or the like along with any comments you might have.

My goal is to end up with a really effecient 2 or preferably 3 zone system in my two story 3400 sq. ft. home. So much of what I've seen seems to involve a lot of compromise along with hit or miss tuning. Not the kind of thing that I want to invest much money in.

Thanks.
