8.5 kWDaikin Skywall 8.5kW Split System
The 8.5 kW Daikin Skywall Split System suits rooms around 55 to 68 square metres as a guide. Sun exposure, ceiling height and insulation move that band, which is why we confirm sizing before we quote.
The Daikin Skywall 8.5kW carries a 2.5-star energy rating for both cooling and heating under the zoned label for Sydney's climate zone. Based on official government test data, it uses 836 kWh per year for cooling and 1,422 kWh for heating. At the median Sydney residential electricity rate of 34.7 cents per kWh as of June 2026, that works out to roughly $290 for cooling, $494 for heating, and around $784 combined across a typical year.
On the efficiency side, the unit has a rated AEER of 3.22 for cooling and an ACOP of 3.27 for heating, meaning it delivers just over three units of heating or cooling for each unit of electricity consumed. It also uses R32 refrigerant, which has a lower global warming potential than older refrigerants.
