Get the most powerful air conditioner and heater with automation features that push efficiency to the next level.

This mini-split air conditioner and heat pump can cool, heat, and dehumidify large areas (9K BTU: 400 sq ft; 12K BTU: 550 sq ft; 18K BTU: 1,000 sq ft; 22K BTU: 1,500 sq ft). It's a quiet, convenient, and efficient way to keep your home comfortable any time of the year whether in the winter or summer, regardless of the temperature outdoors. The fan produces even temperatures silently throughout the area it covers. The variable compressor (DC inverter) provides operates efficiently to meet the cooling and heating needs in your home. It is perfect for homes or establishments that don't have central air conditioning, or for people who do not want to settle for insecure, noisy, and sometimes inadequate window AC units. It's a great solution when replacing zonal electric heat, adding a room, or for hard to reach areas like upstairs rooms or attics.

Auto Restart

The unit returns to its previous settings automatically when power is interrupted.

Hydrophilic Aluminum Fin

The aluminum fin improves cooling efficiency by allowing condensate water to freely flow through the heat exchanger.

Auto Protection and Self Diagnosis

The indoor unit displays system defaults and communicates any need for servicing.

Inner Grooved Copper Tube

This increases refrigerant flow which improves the heat exchange efficiency while lowering power consumption.

Sleep Mode

Efficiently increases or decreases room temperature to provide maximum comfort at night.

Turbo Mode

The unit can very quickly ramp up to a preset temperature by using large diameter cross flow fans to allow high air flow and minimize noise.

Includes integrated thermostat and wireless remote

The wireless remote allows you to turn the unit on and off, set the temperature, and set the fan speed. It controls the thermostat that is integrated into the unit.
