Ductless Air Conditioning & Heating:
In the past, an addition, office, garage or other living space without access to ducting was kept cool by loud, unsightly window and floor units. The noise almost made the conditioned air not worth it. Maybe you’re thinking, “I still use a window unit.” Well guess what? Those days can be over with a ductless air conditioning and heating system!
How Ductless Air Conditioning Works:
Normal residential HVAC systems are called “split systems” because the equipment is split up between inside and outside the home. A ductless system is called a “mini-split” because it too operates in a split system design. A ductless air conditioner or heat pump sits outside the home, and a ductless air handler is mounted inside on an adjacent wall (or recessed in the ceiling).
How Do They Compare?
A ductless air conditioning and heating system offers quiet, efficient comfort that is pretty surprising. The indoor air handlers are designed to condition a 
specific room, but more than one indoor air handler be run from a single outdoor unit. This offers room by room comfort control, without the need for ducting or the noise of portable units.
