3.5 kWHisense J-Series 3.5kW Split System
The 3.5kW Hisense J-Series Split (model HAWJ12KR) 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. If the space is bigger or sun-exposed, step up to the 5.3kW.
Part of the Hisense J-Series Split range, Hisense'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 3.5 kW options, or ask about supply and installation.
About $221 a year at the current Sydney median electricity rate: $80 of cooling plus $141 of heating, from the official GEMS test figures.
The Hisense J-Series 3.5kW uses 276 kWh annually for cooling and 488 kWh annually for heating under official GEMS testing in Sydney's climate zone. These figures reflect real-world performance in typical Sydney conditions and form the basis for the running cost estimate shown on this page. Your actual consumption will depend on how often you run the system and your temperature settings.
