20 kWDaikin Premium Inverter Ducted 20kW Ducted System
The 20kW Daikin Premium Inverter Ducted is sized for large two-storey family homes. As a guide it covers roughly 133 to 160m² of conditioned floor area, depending on zoning, insulation and ceiling height. It sits in the upper half of the Daikin Premium Inverter Ducted range. For more bedrooms or a larger floor plan, the 24kW is the next step up.
The Daikin Premium Inverter Ducted 20kW 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, calculated to June 2026, the system uses 1792 kWh of electricity annually for cooling and 2947 kWh for heating. At the median Sydney residential rate of 34.7 cents per kWh, that works out to roughly $622 for cooling, $1023 for heating, and $1645 combined across a typical year.
On the efficiency side, the system has a rated AEER of 3.28 for cooling and an ACOP of 3.76 for heating, meaning it delivers 3.28 kW of cooling and 3.76 kW of heating for every kilowatt of electricity consumed. It runs on R32 refrigerant, which has a lower global warming potential than older refrigerants.

Daikin Premium Inverter Ducted 20kW: your questions
How much does a 20kW ducted system cost installed?
Installed cost for a ducted system depends on the number of zones, duct runs and outlets, roof space access, whether the outdoor unit needs single or three phase power, and any switchboard work. That is why we quote each home individually rather than publishing a flat rate. Call or email with your floor plan or photos and we give you a fixed quote, usually the same day.
What size home does a 20kW ducted system suit?
As a guide, 20kW of cooling covers roughly 129 to 160 square metres of conditioned area, typically run as zones so you are not cooling the whole home at once. Ceiling height, insulation and glass move that band, so we confirm sizing from your floor plan before anything is ordered. Our capacity calculator gives you a quick starting point.
