What is ducted air conditioning?

Ducted air conditioning uses a central indoor unit connected to ducts and outlets to distribute conditioned air through multiple rooms or zones in the home. It is often considered for whole-home comfort, larger spaces or homes where homeowners want a more integrated heating and cooling solution.

Whether ducted air conditioning is suitable can depend on the size and layout of the home, ceiling or roof space, zoning needs, system capacity, installation requirements, energy efficiency goals and how different areas of the home are used.

An ActronAir installation partner can assess your home and recommend whether ducted air conditioning is the right option for your comfort needs.

Key factors when planning ducted air conditioning

Ducted air conditioning can support whole-home comfort, but the right system design depends on the home, how different spaces are used and what level of control is required. Key planning factors can include home size and layout, ceiling or roof space, ductwork design, zoning, system capacity, installation access and long-term energy efficiency.

Home Size and Layout

The number of rooms, ceiling height, floorplan, insulation, orientation and open-plan areas can all influence ducted air conditioning design and system suitability.

Ceiling or Roof Space

Ducted air conditioning usually requires space for ductwork, outlets and system components. Available ceiling or roof space can influence the installation approach and whether ducted air conditioning is suitable.

Ductwork and Outlet Placement

Ductwork design and outlet placement can affect how air is distributed throughout the home. Planning should consider room layout, airflow, access, ceiling space and how each area will be used.

Zoning and Controls

Zoning and smart controls can help manage comfort across different areas of the home. They may be especially useful for households that use rooms at different times or want more control over whole-home comfort.

Sizing and Capacity

Choosing the right ducted system size is important for comfort, performance and efficiency. System capacity should reflect the home layout, number of rooms, insulation, climate, zoning needs and how the system will be used.

Installation Requirements

Ducted air conditioning installation requirements can vary depending on the property layout, access, ceiling or roof space, ductwork, outlet placement, electrical requirements and whether the home is new, renovated or being retrofitted.

Ducted vs split system air conditioning​

Ducted and split system air conditioning can suit different homes, layouts and comfort needs.

Ducted air conditioning may be suitable for whole-home comfort, larger spaces, new builds, renovations or households wanting zoning and centralised control across multiple rooms.

Split system air conditioning may be suitable for individual rooms, smaller spaces, apartments or homes where a whole-home ducted system is not required or practical.

The right option depends on your home layout, how many rooms need heating or cooling, installation requirements, available installation space, budget, zoning needs and long-term comfort goals.
