5.3 kWHisense J-Series 5.3kW Split System
The 5.3kW Hisense J-Series Split (model HAWJ18KR) is sized for living rooms and master suites. As a guide it suits a typical insulated room of roughly 35 to 42m²; sun exposure and ceiling height move that band. If the space is bigger or sun-exposed, step up to the 7.1kW.
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 5.3 kW options, or ask about supply and installation.
About $373 a year at the current Sydney median electricity rate: $145 of cooling plus $228 of heating, from the official GEMS test figures.
The Hisense J-Series 5.3kW uses 502 kWh annually for cooling and 790 kWh annually for heating under official GEMS testing in Sydney's climate zone. These figures reflect real-world usage patterns for the area and form the basis of running cost estimates. The system carries a 2.5-star cooling rating and a 2-star heating rating in the Sydney zone, indicating moderate efficiency relative to other units in its class.
Efficiency is measured by AEER (cooling) at 3.32 and ACOP (heating) at 3.71, which indicates how much cooling or heating output you receive per kilowatt of electricity consumed. The system uses R32 refrigerant. Your actual running costs will depend on your local electricity rate and how often you run the unit.
