Traditional central air conditioners are bulky, sometimes complicated and very heavy. Whereas, mini splits are small in size and great because they do not require any ductwork to function. They feature both an indoor and an outdoor unit that is connected by small cables and a line of refrigerant running through a tiny hole in the wall. A ductless HVAC unit provides heating and cooling options that can be an energy efficient way to distribute air in any type of environment. Ductless mini split systems are unique because they are entirely self-sufficient.
