I'm seriously considering going with LG's flex mini-split heat pump system. I really like the idea of have zone control with every room, and duct work is not feasible for the house in question. The reason I like LG's lineup over other brands I've researched is the aesthetics of the indoor units. However, I'm not willing to sacrifice performance over style (the same might not be so for my wife).

The bottom line is, has anyone had any experience with LG?

What I'm looking for in the system is efficiency and comfort. It will also need to be able to heat my entire house in the winter, and cool it in the summer. Vents are not possible. Without getting into Manual J-load calculations and system sizing, I would love to hear different opinions on other brands if you have them.
