The ComfortAire ductless wall mounted mini-splits systems are lightweight, compact, whisper quiet. These systems are ideal in areas where it’s impractical to install ductwork. These systems only require a small opening to connect the indoor unit to the outdoor unit which makes installation simple. ComfortAire systems are also much more attractive and more secure than traditional window units. They are easily installed in bedrooms, sun rooms, offices, cottages, arena skyboxes, and historical buildings.
