It’s hard to say which is the greatest benefit of a 3 zone ductless mini split AC system – the “split” part or the “ductless” part.

By split, we mean that the essential components of the air conditioning process are located separately – the condenser/compressor on the outside, and the air handler/evaporator coil on the inside. With a 3 zone ductless mini split AC, the inside part is actually three air handlers, each possessing its own air delivery system and its own thermostat.

By ductless, we mean that this system does not use traditional ductwork. Therefore, there is no need to install ductwork or connect to existing ductwork. The only connection between the air handler(s) and the condenser is the refrigerant lines, which pass through a three-inch hole in the exterior wall.

All these tri zone mini split systems include a heat pump. A heat pump is not an additional component, but a system of “reversing” the air conditioning process in the winter, where the evaporator coils and condenser coils swap jobs. Heat is extracted from the outside air and dispersed inside.

As a general rule, each zone requires a minimum of 6,000 BTUs for effective heating and cooling, but factors like high ceilings, large open areas and large windows can bump up the need for BTUs. The chart of shop-by filters on the left shows the various mini split systems by size. Each number represents an air handler, and the value of the number represents its capacity in terms of BTUs x 1000. For example, 6+9+12 means the system has one air handler rated at 6,000 BTUs, one air handler rated at 9,000 BTUs and one air handler rated at 12,000 BTUs. has an amazing inventory of Mitsubishi mini split systems, allowing us to put the quality from one of the world’s most prolific producers of HVAC equipment into the hands of customers at affordable prices.
