An 18000-BTU mini split sized for a genuinely large room, covering up to 1000 sq ft from a single head on a 208-230V supply, with cooling and heating both rated 18000 BTU so the unit is not simply an air conditioner that also blows warm. Inverter technology is what maximises efficiency and minimises running cost at 20 SEER2 and HSPF2 10, and chassis electrical heating in the outdoor unit keeps operation stable when the weather turns cold, with an ambient envelope from minus 4 to 122 degrees Fahrenheit. Seven modes and eight fan speeds deliver year-round comfort, including a mute mode, a turbo mode and a gentle wind setting for the times when neither extreme is wanted. Control runs through an app, a voice assistant or the included remote, and the unit is compatible with Amazon Alexa and Google Assistant. Nights are handled by a sleep mode paired with a screen off function, holding indoor noise at 28 dB with no display glow, and a 24-hour timer allows personalised scheduling. 4D auto swing distributes air evenly through a large space rather than leaving cold and warm pockets. Temperature sets from 60 to 88 degrees, the system moves 617 CFM and clears 111.6 pints a day on R32 refrigerant, drawing 1580W and 7.0A in cooling against 1540W and 6.8A in heating. A child lock, self-clean function and washable filters complete daily use, and it ships in 2 cartons.
