When the setup is complete, it will look something similar to the illustration on the right; where the sleek air-handler is mounted on a wall and the noisy, large compressor fan - motor is isolated outside. This setup not only eliminates noise pollution but also free's up indoor space. Because the air is cooled and released directly at the air handler and not losing any temperature traveling through conduits of duct-work, the ductless split cooling system is up to 30% more energy efficient than central air.
