Ducted
Whole-home and multi-zone control
Ducted air conditioning and ducted systems can serve a whole home or multiple building zones. Air is delivered through concealed ductwork, ceiling outlets and central controls.

Load-based capacity and zoning
Heating and cooling comfort
Comfort depends on choosing the right system type, zoning and capacity.
Air conditioning design is not only about selecting equipment. The system must suit the building layout, occupied zones and available space for indoor and outdoor equipment.
SmartHeat supports residential air conditioning systems and commercial air conditioning systems for air conditioning Sydney projects. This includes new homes, major renovations, multi-residential developments and commercial buildings.
System options
Choose the air conditioning system around the building, zones and project requirements.
Home air conditioning, cooling and reverse-cycle comfort can use ducted systems, multi-split, bulkhead or other heat-pump-based systems. The right option depends on the building layout, zones, heat loads and installation limits.
Multi-split
Multiple rooms with shared outdoor equipment
Multi-split systems can serve several individual rooms or zones using multiple indoor air conditioning units connected to shared outdoor equipment.
Bulkhead
Concealed architectural integration
Bulkhead systems can suit projects where indoor equipment needs to be concealed within ceiling, joinery or other architectural zones.
Reverse-cycle
Year-round heating and cooling
Reverse-cycle systems provide cooling in summer and efficient space heating in winter for residential and commercial projects.
Design process
Capacity and zoning should be designed, not guessed.
Proper capacity calculation is essential. Before equipment is selected, the design should check floor area, glazing, orientation, insulation, occupancy, equipment loads and local climate.
- 01
Define the building zones
Confirm which rooms, residential areas or commercial zones require heating, cooling and independent temperature control.
- 02
Calculate the load
Review floor area, ceiling height, glazing, orientation, shading, insulation, occupancy and internal equipment loads.
- 03
Select the system
Compare each type of air conditioner against the project needs. This may include ducted, multi-split, bulkhead and other heat-pump-based approaches.
- 04
Coordinate installation
Plan air conditioning installations around outdoor unit locations, pipework, ductwork, outlets and controls. Drainage, electrical requirements and service access should also be allowed for.
Technical planning
Building use, zoning and installation constraints shape the final design.
A good air conditioning design balances comfort, capacity and running cost. It also accounts for building load, zoning, equipment locations, airflow, controls and energy efficiency.
- Building load
- Floor area, ceiling height, occupancy, glazing and insulation all affect heating and cooling capacity. Equipment, lighting and orientation also need to be checked.
- System type
- Ducted, multi-split and bulkhead systems suit different building layouts, zoning needs and architectural constraints.
- Outdoor units
- Outdoor air conditioner equipment location affects noise, airflow, pipe routes, appearance, service access and available space.
- Ductwork and outlets
- Duct routes, outlet positions and return-air locations should be coordinated with ceilings, structure, lighting and joinery.
- Controls
- Sensors, zone controllers and central interfaces should match how each occupied area is used throughout the day.
Suitable projects

- Whole-home ducted air conditioning
- New homes and major residential renovations
- Multi-zone residential projects
- Apartments and multi-residential developments
- Offices, retail spaces and commercial tenancies
- Commercial refurbishments and new developments
FAQ
Common residential and commercial air conditioning systems questions.
What is ducted air conditioning?
Ducted air conditioning uses central indoor equipment and concealed ductwork to distribute conditioned air through ceiling or wall outlets. It can serve a whole home, multiple residential zones or larger commercial areas.
When is a multi-split system useful?
A split system air conditioner can suit one room. A multi-split system can suit homes, apartments and offices where several indoor units are needed but outdoor unit space is limited.
What is bulkhead air conditioning?
A bulkhead air conditioning system conceals the indoor unit within a ceiling, joinery or architectural bulkhead. It can provide discreet air distribution where visible wall-mounted equipment is not preferred.
Can air conditioning also provide heating?
Yes. Reverse-cycle air conditioning can provide cooling in summer and heating in winter, allowing one system to support year-round comfort.
How is the required system capacity calculated?
Capacity should be based on the building, not a rough estimate. Floor area, ceiling height, occupancy, glazing, shading, insulation, equipment loads and local climate all affect an AC unit or wider AC system.
