At 24 SEER2 cooling and 10.5 HSPF2 heating, this three-zone ductless system is rated well above the class minimum, and Energy Star certification backs that up. The efficiency comes from an inverter compressor paired with R454B refrigerant, with one 27000-BTU outdoor unit feeding all three heads. Head sizing is two 9000-BTU units and one 12000-BTU unit: the 9000-BTU heads cover about 450 square feet each at 326 CFM, and the 12000-BTU head takes roughly 750 square feet at 500 CFM. Dry mode pulls 55.8 pints a day from each small zone and 81.2 pints from the larger one. Every zone sets its own temperature from 60 to 88 degrees Fahrenheit through a smartphone app, the remote at 39.5 feet, or a voice command, with 7 operating modes and 8 fan speeds to work through. Comfort details matter overnight: 30 decibels indoors, sleep mode, a screen off function, 4D swing so air is not driven at one point, and a child lock so a setting stays where it was left. A 24-hour timer covers routine scheduling, and chassis electrical heating keeps the outdoor unit consistent in cold conditions. Filters pull out and wash, and a self-clean cycle handles the coil. The outdoor unit stands 38.5 by 16.57 by 31.61 inches at 119 pounds, each 9000-BTU head is 32.28 by 7.68 by 12.05 inches at 20.7 pounds, and the 12000-BTU head is 36.22 by 7.68 by 12.05 inches at 24.3 pounds. Three 16-foot copper line pairs, three 19-foot communication wires, three drain hoses, three remote sets, six wall caps, four mounting foot pads, tape, putty and screw kits are included.
