energy efficient split systems 3

My neighbor just got an energy efficient split system installed, and it's surprisingly quiet. I've been reading about how these ductless heat pumps use inverter technology to adjust their power draw, which really cuts down on electricity bills compared to older window units. They also allow zone cooling in the house, so you're not wasting energy cooling empty rooms. I'm seriously considering one for my home's hot upstairs.
