A ductless system consists of one outdoor unit and one indoor unit connected by refrigerant tubing and electrical wiring. Refrigerant is channeled directly to the source of the indoor unit, which typically consists of the air handler. The outdoor unit houses the compressor that brings warm or cold air into the space. Some models can have multiple room terminals hooked up to one single compressor.
The ductless HVAC system works similarly to an air conditioning system, as it moves heat from one place to another. A reversing valve is then used in the warmer months to switch the flow of refrigerant to allow for cooling applications. From there, heat is absorbed from the inside of your home and moved outside to keep the space cool. Installation of these units is relatively simple as it only requires a hole to be drilled into a wall for the wiring and refrigerant line.
On our website, you can choose between a single-room and a multi-room ductless mini-split system.
A single-zone configuration would require just three basic main requirements: one outdoor unit, one indoor unit, and a refrigerant lineset. On the contrary, a multi-zone configuration would require more combinations of this system, and is typically for those who want to cool an entire space or home, and not just one or two rooms.
