A room air conditioner and/or heat pump is shown with a main control and a user interface. The user interface is mounted on a user interface mount attached to the front of a main unit, but behind the bezel. The user interface mount is used to (a) insert or remove the main unit, (b) secure and protect wiring cables, (c) mount the user interface thereon, (d) direct a filter into position, (e) provide a slot for a fresh air slide, and (f) direct a bezel into position. A main control housing allows access there through to a main control circuit board, but prevents moisture from dripping on the main control circuit board. A dual filter element is located behind a double hinged door. Channels and flanges direct and secure the bezel into position.
