Discreet whole-home reverse-cycle comfort.
The unit is only one part of a ducted system. Correct heat-load selection, duct design, return air, zoning, electrical coordination and commissioning determine how the finished system performs.

Six details we treat as one system
A neat ceiling grille does not guarantee good performance. Airflow and equipment selection are planned together before the installation is committed.
Heat load
Glazing, insulation, orientation, floor plan and occupancy affect the capacity required.
Duct sizing
Diameter, length, bends and branch layout affect static pressure and room airflow.
Return air
The return path is sized to support airflow while managing noise.
Zoning
Zone control is planned with minimum airflow and system operation in mind.
Electrical supply
Supply, circuit protection, isolator and switchboard capacity are checked early.
Service access
Indoor and outdoor equipment must remain practical to inspect and maintain.
Capacity and control options without overcomplicating the quote
Daikin currently lists Premium Inverter Ducted capacities across a broad residential range. We use the manufacturer’s current data and compatible controls as part of the equipment selection, then present the proposed model and installation scope clearly in the quote.
2026
VEU heating & cooling rules are changing
Victoria has announced changes from 30 September 2026, including a $3,000 minimum co-payment (including GST) for ducted reverse-cycle and multi-split systems with cooling capacity of 10 kW or more, plus a residential multi-split incentive cap. We confirm the rules and rebate value that apply on the date of your installation.
