8.5 kWDaikin Inverter Ducted 8.5kW Ducted System
The 8.5kW Daikin 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 Inverter Ducted range. For more bedrooms or a larger floor plan, the 10kW is the next step up.
The Daikin Inverter Ducted 8.5kW carries a 2-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 897 kWh annually for cooling and 1,519 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 $311 for cooling, $527 for heating, and $838 combined across a full year.
The unit's rated efficiency figures are an AEER of 3.30 for cooling and an ACOP of 3.51 for heating, meaning it delivers around 3.3 units of cooling and 3.5 units of heating for every unit of electricity consumed. These figures come from the same government GEMS registration testing used for the star rating label.
