Our verdict

A window unit for a large bedroom or small apartment that needs cooling, dehumidifying and light heat from one appliance. The heat function drops out in cold outdoor weather, so it is no winter heater.

Overview

Mounting in a double hung window with the supplied installation kit, this inverter air conditioner cools, dries and adds supplemental heat from a single chassis. A variable-speed compressor adjusts output to the room, and a remote, an app or voice commands handle the settings.

The inverter compressor ramps output to the room load, which smooths temperature and trims running draw, and the heat mode stretches use into the shoulder seasons. The heat function fails in cold outdoor weather, and the window sash has to open far enough to take the chassis.

Who it's for

A large bedroom, studio or similar single room with a double hung window suits this unit, especially where quiet running matters for sleep or video calls. Households that need dependable heat on cold days, or have other window styles, should look elsewhere.

Pros and cons

Pros
  • Inverter compressor with variable-speed operation
  • Heats as well as cools and dehumidifies
  • Remote, app and voice control
  • Rated for large rooms
Cons
  • Heat mode limited by outdoor temperature
  • Needs a double hung window
  • Heavy unit to lift into a window

Performance notes

Cooling output is set by the inverter compressor, which modulates speed to the room load instead of switching fully on and off. Noise is lowest on the low fan setting, and the heat function depends on outdoor air staying above the cutoff in the listing. Coverage depends on room size and sealing, so the rated floor area is a limit for a well-sealed space.
