Open layouts up to 1250 sq ft stay comfortable with this 17000 Btu ductless mini split that pairs strong cooling with 16500 Btu heating from a 35.8-inch indoor unit. The 17 SEER2 inverter, R32 refrigerant and 8.5 HSPF2 heating balance performance and operating cost. Smart WiFi, voice assistant support, seven modes and chassis heating keep cold-climate use predictable, and 4D auto swing, a 24-hour timer and 28 dB indoor sound round it out.
