Concealed heating and cooling, designed around the building
The Samsung Duct S2+ places the indoor unit out of sight and delivers conditioned air through ductwork and ceiling outlets. Airmax designs the capacity, outlets and controls around the building rather than relying on a one-size-fits-all package.
Why consider Duct S2+
- Six nominal capacities from 5.2 kW to 15.5 kW cooling.
- The 10-15.5 kW indoor units split into fan and heat-exchanger sections to help with tight roof-space access.
- R32 refrigerant and single-phase 220-240 V power across the range.
- SmartThings remote control is available with Samsung’s optional Wi-Fi connection kit.

Frequently asked questions
Can different areas be controlled separately?
Zoning can be designed into a ducted installation. The final controls and zoning components depend on the property and are specified in the quote.
Will the indoor unit fit my roof space?
Airmax checks access and clearances during the site assessment. The 10-15.5 kW Duct S2+ indoor units can be separated into sections to assist installation in tighter spaces.
