We have been selling / installing Fujitsu Ductless mini splits AC systems for the last 14 years and I must say they are the most dependable, most efficient, and the quietest systems that we have seen. These systems are perfect for the garage (which is where 90% of our installs are located), in a workout room, or a casita. Fujitsu Ductless mini splits are inverter driven, which means, they adjust according to load. A two ton system will adjust down to a one ton or even a 3/4 ton if that’s what the load is or the amount of heat removal is required.
