What is a room air conditioner and a mini-split?
Room Air Conditioners: Mount in a window or through-the-wall. Perfect for cooling a single room. Many special features are available like remote controlled operation, programmable timers, one touch cooling, etc… Ductless Split Systems: Available as in-wall, floor and ceiling mounted units. Connected by refrigeration lines and wiring to an outdoor unit. Great for renovations, room additions and zone cooling. Exceptionally quiet because the compressor is located outdoors.
