Two 12000-BTU wall heads on a 35000-BTU outdoor unit is a configuration with room to spare: each head is rated for roughly 750 square feet at 500 CFM, and the condenser behind them is the largest in the family at 42.28 by 18.43 by 33.58 inches and 145.5 pounds. Each zone runs its own temperature between 60 and 88 degrees Fahrenheit, and dry mode clears 81.2 pints of moisture a day per head. Efficiency is 22.5 SEER2 in cooling and 10 HSPF2 in heating, produced by an inverter compressor working with R454B refrigerant, and the system carries Energy Star certification. Chassis electrical heating inside the outdoor unit is what keeps output consistent once outdoor temperatures drop. Control is flexible rather than fixed to one device: a smartphone app, the remote at up to 39.5 feet, or a voice command, all reaching the same seven operating modes and eight fan speeds. 4D swing then distributes the air evenly instead of aiming it at one spot, a 24-hour timer covers scheduling while saving energy, and a child lock prevents accidental changes to settings. For overnight running there is sleep mode alongside a screen off function, with indoor sound at 30 decibels. Upkeep is limited to a removable washable filter and a self-clean function that keeps airflow fresher over time. Each 12000-BTU head measures 36.22 by 7.68 by 12.05 inches at 24.3 pounds. The package carries two 16-foot copper gas and liquid pipe pairs, two 19-foot communication wires, drain hoses, remote and holder sets, wall sleeves, four wall caps, tape, putty and screw kits.
