The Keystone 12,000 BTU 115V through-the-wall air conditioner with "Follow Me" remote control is perfect for cooling a room up to 550 square feet. It has electronic controls with LED display and a temperature sensing LCD remote control allowing you to conveniently see, set and maintain the room temperature from across the room. Money saving features include energy saver mode, sleep mode and a programmable 24-hour timer. Plus quiet operation (56.5 dB on low) helps you get a good night's sleep. This unit is designed for through-the-wall installation and is not designed for standard window installation (WALL SLEEVE SOLD SEPARATELY).
fit in the window sleeve perfectly and the enclosed installation kit was great.
it's cooling away now. just need to get familiar with all the features.
not sure why the through-the-wall models are so expensive but this one was on par with similar models price wise.
