8.5 kWDaikin Premium Inverter Ducted 8.5kW Ducted System
The 8.5kW Daikin Premium Inverter Ducted is sized for smaller homes, or zoning part of a larger one. As a guide it covers roughly 57 to 68m² of conditioned floor area, depending on zoning, insulation and ceiling height. It sits in the lower half of the Daikin Premium Inverter Ducted range. For more bedrooms or a larger floor plan, the 10kW is the next step up.
The Daikin Premium Inverter Ducted 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 for Sydney, the system uses 777 kWh for cooling and 1383 kWh for heating annually, putting estimated running costs at around $270 for cooling and $480 for heating, or roughly $750 across a full year. Those figures use the median Sydney residential electricity rate of 34.7 cents per kWh across 170 plans, calculated as of June 2026.
On efficiency, the unit achieves a rated AEER of 3.54 for cooling and an ACOP of 3.98 for heating, meaning it delivers more than three and a half kilowatts of cooling and nearly four kilowatts of heating for every kilowatt of electricity consumed. The refrigerant is R32, which has a lower global warming potential than older refrigerants such as R410A.
