Bests & Worsts Reviews from Amazon

This is an easy to install and use A/C that fits in tight spaces. The compressor and fan are quiet for its size. Compressor engages as needed only when cooling. Fan runs constantly to recirculate the air inside my room. On the outside, the exhaust vents must be free from debris or foliage in order for cooling to occur inside my room. Do not cover or inhibit the exhaust vents. To install this A/C, opening must be at least 13.125 in height and 16.5 in width, but if needs be, you can reduce the height by an inch by NOT installing the top brace. My pictures show the EER of 11.1 and my setup for my A/C installation thru my wall, not a window.
