Wall Mount (High-Wall)

The most common type of indoor air handler for mini splits is the high-wall mount — a slim unit installed near the top of the wall, usually 6–12 inches from the ceiling. It blows conditioned air down and across the room at an angle, which distributes temperature evenly. High-wall units are popular because they stay out of the way, look reasonably clean on the wall, and are easy to access for filter cleaning. There are other air handler styles — ceiling cassettes, floor mounts, concealed ducted — but the high-wall is the standard for most homes.
