The evolution of the loud, clunky air conditioner has arrived. Designed for open window, flexible installation, this Perfect Aire 12,000 BTU window air conditioner with smart controls and smart home connectivity silently cools rooms up to 550 sq. ft. The unique U-Shaped design blocks the compressor noise outside, allowing ultra-quiet operation as low as 39 dBA, while still slowing for the ability to open and close your window. Inverter technology makes this window AC ultra-efficient, using 35% less energy compared to traditional window ACs. Best yet, this sleek, stylish window AC fits seamlessly into most smart homes, with Google Assistant and Amazon Alexa connectivity. Or, control from your smart phone with the convenient app.
