Ductless systems allow for flexibility. A single-zone (also called a mini-split) ductless system allows you to control the temperature of one room by connecting an outdoor unit to an indoor unit, with no ductwork needed. An outdoor mini-split unit is placed outside your home and is connected to an indoor mini-split unit by small cables and a refrigerant line through a hole in the wall.

Daikin

All Daikin ductless cooling systems feature streamlined, mounted indoor units paired with quiet and compact outdoor units.

As you can likely gather from its name, a mini-split/ductless system is a split system, which means it has components that are located inside and outside the home. However, unlike traditional split HVAC systems, ductless units do not rely on air ducts to route air throughout your home. Rather, a ductless air conditioner is designed to heat or cool a single room, a zone or an addition to your home that may lack or cannot accommodate ductwork.

Mitsubishi

Mitsubishi Electric heat pumps are equipped with Variable Compressor Speed Inverter (VCSI) technology that can adjust compressor speed based on demand. By slightly adjusting its compressor speed rather than shutting on and off completely, the system can operate at partial load for maximum efficiency; therefore the system uses only the minimum amount of energy required to maintain ideal room conditions.
