5 kWSamsung Aero 5kW Split System
The 5kW Samsung Aero (model AR18DXFZCWKNSA) is sized for living rooms and master suites. As a guide it suits a typical insulated room of roughly 33 to 40m²; sun exposure and ceiling height move that band. 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 6.8kW.
The Samsung Aero 5kW uses 414 kWh annually for cooling and 819 kWh annually for heating under standard Sydney climate test conditions. These figures are based on official GEMS registration data for the Sydney zone. The system carries a 3.5-star cooling efficiency rating and a 2-star heating efficiency rating for Sydney conditions.
The unit delivers a rated cooling efficiency (AEER) of 3.58 and heating efficiency (ACOP) of 3.52. Your actual energy consumption will vary depending on local weather, indoor temperatures you set, and how often you run the system. The exact running cost appears separately on this page and adjusts automatically with current Sydney electricity rates.
