Sweltering season is soon upon us, so you’ll want to come equipped with our all-time favorite window AC. Its U-shaped design makes it a, ahem, breeze to install, its compressor sits outside your window for a quieter operation and it effectively cools areas of up to 450 square feet. Best of all, you can easily open and close your window without having to dismantle it, and you can use its companion app for hassle-free control of the temperature in your home.
