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 cools a room of up to about 39 to 45 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. 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, see every 5kW split system ranked by running cost, or ask about supply and installation.
About $428 a year at the current Sydney median electricity rate: $166 of cooling plus $262 of heating, from the official GEMS test figures.
