6.8 kWSamsung Aero 6.8kW Split System
The 6.8kW Samsung Aero is sized for large living rooms and open-plan areas. As a guide, it cools a room of up to about 50 to 57 m². That is from Mitsubishi Heavy Industries' sizing chart for an insulated room: the larger figure if it faces north, the smaller if it faces east. Western sun, poor insulation and high ceilings bring it down. Like the rest of the Aero range it pairs Samsung’s Digital Inverter Boost compressor with SmartThings app control. If the space is bigger, has high ceilings or strong afternoon sun, step up to the 8kW.
Part of the Samsung Aero Split System range, Samsung's split system line, in 5 sizes. Running costs below use the Sydney median rate; the Eastern Suburbs and Western Sydney pages cost systems on their own network tariffs. Check the size against your rooms, compare it with other 6.8 kW options, see every 7kW split system ranked by running cost, or ask about supply and installation.
About $560 a year at the current Sydney median electricity rate: $210 of cooling plus $350 of heating, from the official GEMS test figures.
The Samsung Aero 6.8kW is rated at 3 stars for cooling efficiency and 2 stars for heating, based on government energy labelling for Sydney's climate zone. Under standard test conditions, it uses 633 kWh annually for cooling and 1057 kWh annually for heating. These figures come from official GEMS registration data for Sydney.
The system achieves a cooling efficiency rating (AEER) of 3.29 and a heating efficiency rating (ACOP) of 3.27. It uses R32 refrigerant. Running costs depend on your local electricity rate and how often you operate the unit, which varies between households and seasons.
