Unlike standard window air conditioners that can obstruct outside views and be a hassle to install, this unit rises only 4″ above a windowsill and sets up with minimal effort. It efficiently cools up to 375′ sq. with 8,000 BTUs of power and has a built-in evaporative dehumidifier. An included remote provides across-the-room control of temperature, three fan speeds, and a 24-hour timer.
