3.5 kWFujitsu Lifestyle 3.5kW Split System
The 3.5kW Fujitsu Lifestyle Split (model ASTG12KMTC) is sized for large bedrooms and smaller living rooms. As a guide it suits a typical insulated room of roughly 23 to 28m²; sun exposure and ceiling height move that band. It sits in the lower half of the Fujitsu Lifestyle Split range. If the space is bigger, has high ceilings or strong afternoon sun, step up to the 5kW.
The Fujitsu Lifestyle 3.5kW uses 237 kWh annually for cooling and 419 kWh for heating under official Sydney climate testing. These figures are based on typical household use patterns registered with the government energy rating scheme for Sydney's zone. The system carries a 4.5-star cooling efficiency rating and 3-star heating rating under the same conditions, reflecting its performance in a Sydney climate.
The unit's rated cooling efficiency (AEER) is 3.92 and heating efficiency (ACOP) is 4.67. These metrics indicate how much cooling or heating output you receive per kilowatt of energy consumed. Combined with the official annual energy consumption figures, they establish the basis for calculating your running costs under typical Sydney usage patterns.
