What is "Mini-split" Anyway?

Mitsubishi Electric helped pioneer the mini-split (or ductless) technology as a means of providing Japan's growing population with a highly efficient way to cool and heat their homes and businesses. They designed the Mr. Slim system to fit into spaces that could not otherwise have been effectively heated or cooled due to the close proximity of Japan's buildings, plus they needed a system that was extremely quiet.

The term ductless means simply that no ductwork is involved. The system is comprised of two units: a slim-line outdoor condenser, and an indoor air handler. The condenser supplies coolant to the air handler through refrigerant lines that run through a small opening in the wall or ceiling and into the back of the unit. The air handler takes in supply air from the room through the front grill and dispenses the newly-cooled air back into the room. For certain models special filters are available that promote added humidity control and filtration.
