One Unit, All Seasons — 11500 BTU for 550 Sq.Ft.: This ductless mini split replaces your window AC, space heater, and dehumidifier. It heats reliably down to -4°F with auto-defrost and maintains stable cooling at outdoor temperatures up to 122°F. Cool, Heat, Fan, Dehumidify, Turbo, Sleep, and Eco modes plus a 24H timer deliver customizable comfort for bedrooms, home offices, garages, basements, and living areas up to 550 sq.ft.
Ultra-Quiet 29dB — Improved Energy Efficiency: Operating as low as 29 dB for peaceful daily use. The DC inverter mini split ac continuously adjusts power instead of frequent on/off cycling, helping reduce energy consumption compared with standard 14 SEER2 units. Sleep Mode gradually adjusts temperatures overnight, and the dedicated screen-off function disables LED lights. It uses low-GWP R32 refrigerant and is certified ETL & AHRI verified.
Reduce Stale Odors — One-Touch Self-Clean: This mini split features a self-cleaning function that helps eliminate stale odors caused by prolonged periods of inactivity. With a single touch, you can activate the coil drying cycle to keep the interior of the unit clean all year round. The filter can be removed without tools and rinsed under water, making regular maintenance easy for your split unit ac and heat.
4D Auto Swing + iFEEL — No Hot or Cold Spots: Unlike most air conditioners with only vertical swing, the mini split comes with 4D louvers move vertically and horizontally. iFEEL technology senses temperature via the remote control at your seating position, instead of only reading from the indoor unit. Enjoy balanced airflow and reduce uncomfortable direct air blasts.
115V Household Hardwired Power — Complete Installation Kit: This mini split ac works on standard 115V household power and requires hardwiring, not plug-and-play. Factory pre-charged R32 refrigerant, paired with a 16.42ft copper line set and full installation kit (power cord not included). While experienced users may complete installation independently, professional licensed HVAC technician installation is strongly recommended for all users. Vacuum-pumping is required before startup. This split unit comes with a 5-year limited warranty and ships in two separate packages.
Customers find the mini split air conditioner exceeds expectations and is straightforward to install with clear instructions. They appreciate its cooling performance, with one customer noting it drops temperatures from 86°F to 72°F in 10 minutes, and its energy efficiency in saving on utility bills. Customers praise its quiet operation, efficient mini split design, and ability to keep rooms comfortable.
