Since the compressor sits on the outside, the Ductless Mini Split Air Conditioner is very quiet and efficient. Also, since Ductless Mini Split Air Conditioners have no ducts; they avoid the energy losses associated with the ductwork of central forced Air systems. Duct losses can account for more than 30% of energy consumption for space conditioning, especially if the ducts are in unconditioned spaces such as an attic.
