Working to keep you and your family comfortable all year round

A Samsung inverter reverse cycle Ducted Air Conditioner is designed to enable each room in your home to be cooled or heated by one system. Ducted Systems are also relatively unobtrusive as the conditioned air is distributed through ducts hidden in your roof space to outlets in the ceiling of each room. The primary components of your Samsung Ducted System consist of the indoor unit, outdoor unit and controller.

Powerful AirflowPowerful Airflow

Samsung Duct S indoor units contain up to 3 fans* and are designed to handle duct lengths with static pressures of up to 200pa**; to provide powerful airflow in your home.

3-way service access for easy maintenance

Most ducted air conditioners are installed in a variety of locations, so they need to be accessed in different ways for maintenance. The Samsung DUCT S Air Conditioner is designed to be accessed from three directions – top, side and bottom – using an easy to remove Slide Fit cover. As a result, it’s much easier to maintain wherever it's installed. 

Comfortable and Reliable

Samsung Ducted Air Conditioners are designed to keep on working, even on those extremely hot or cold days. With an operating range of -15°C to 50°C outside air temperature for cooling, and -20°C to 24°C for heating, you can be assured that your unit can work when you need it*

Flat Micro-Channel Technology
