They are awesome units. We've had our Mitsubishi units for two years now and love them, extremely quiet and efficient. We have four head units, two on each floor and they work great. The tech had to run a vacuum pump for six hours to reach the proper amount of vacuum. It was a good and much needed break for him because it took them a day and a half to drill the holes through the red brick on the exterior of the house. Then they had to deal with the tops of the sill plates above the windows. And of all things it was 90 degrees that week. Burned up 2 masonry whole saws in the process!
Looking forward to seeing your progress on the layout!
