Nothing hangs on the wall with this configuration. Both indoor units are concealed ducted air handlers that stay hidden and deliver through ductwork, which is what keeps homes, offices and light commercial spaces looking neat. The pair is an 18000-BTU handler and a 24000-BTU handler on one 35000-BTU outdoor unit, each zone adjusted on its own wall thermostat as well as from a smartphone app, the remote at up to 39.2 feet, or by voice. The 18000-BTU handler covers about 1250 square feet at 500 CFM and pulls 111.6 pints of moisture a day, while the 24000-BTU handler takes roughly 1500 square feet at 741 CFM and 131.9 pints. Setpoints run from 60 to 88 degrees Fahrenheit, with 7 operating modes, 8 fan speeds and 4D auto swing balancing distribution. Inverter technology holds temperature more steadily than fixed-speed equipment and, with R454B refrigerant, reaches 22.5 SEER2 in cooling and 10 HSPF2 in heating. Chassis electrical heating inside the outdoor unit keeps performance reliable in colder conditions. Indoor sound sits at 28 decibels, sleep mode and a screen off function suit overnight running, a 24-hour timer covers scheduling, and a child lock prevents unwanted changes. Self-clean handles the coil. The 18000-BTU handler is 36.22 by 17.8 by 7.87 inches at 39.7 pounds, the 24000-BTU handler 43.31 by 17.8 by 7.87 inches at 50.7 pounds, and the outdoor unit 42.28 by 18.43 by 33.58 inches at 145.5 pounds. Two wall thermostats, two 16-foot copper pipe pairs, two 19-foot communication wires, four mounting foot pads, tape, putty and screw kits are included.
