Magic AC Mount is an innovative, patent-pending window air conditioner mounting system that installs completely from inside the room no drilling, screws, or exterior brackets required. Designed to fit windows from 24" to 44" and support units up to 220 lbs., it attaches to the window jamb instead of the window frame, helping protect replacement windows while providing a safe, secure installation. Magic AC Mount allows the window to be opened after installation, a unique advantage over conventional A/C brackets. The system uses advanced 3M technology, meets UL 484 requirements, complies with NYC Local Law 11, and is compatible with virtually all window air conditioners.
