In my area, the HVAC companies that will do mini-splits are extremely overpriced (I think they usually only use them for commercial installations). Quoted me $25k for 4 minisplits. Did it my self, including electrical, with Mr Cool minisplits for something like $10k. The bad thing is I think Mr Cool units don't give you the full BTU unless you manually put it on "turbo" mode, and the thermostat isn't accurate (I have to recalibrate it depending on the season).
