Air conditioner covers fit over the front grille or outside cabinet of an idle AC unit to block drafts, dirt, and allergens from entering a building. They're commonly installed at the end of the cooling season to cover AC units that won't be used for an extended period of time.

Air conditioner grilles fasten to an air conditioner sleeve, plenum, or wall cutout to cover the wall opening and protect the AC coil fins from damage. They allow air to flow to and from air conditioners while providing a finished look on wall openings.

Air conditioner installation accessories are tools and hardware for mounting wall air conditioners. They're used for applications such as providing support for AC units and wiring to an electrical source.

Air conditioner wall sleeves slide into a cutout to hold wall-mounted air conditioners. They provide a stable platform for AC units and help form a seal around the units to insulate against energy loss and block out rain.

Thermostats sense temperatures within a room and automatically turn air conditioners on and off based on temperature setpoints. They have a sensor that monitors temperatures and a control panel for adjusting the setpoints. They're typically mounted on an inside wall.

Air conditioner wall plenums install into a wall opening for holding the exterior portion of a vertical packaged air conditioner's chassis. They consist of an interior and exterior plenum that telescope to provide a snug fit between the chassis and the wall.

Air conditioner drain kits contain fittings and hardware for routing condensate to a drain. They collect water dripping from the air conditioner coils and direct it into a condensate drain line to prevent puddling around the AC unit. These kits provide a connection between a wall sleeve's outside corners or base pan and the drain line.
