If you’re looking for a whole-home or whole-office air conditioning solution, ducted air conditioning is a popular and efficient choice. Designed to cool or heat multiple rooms from a central point, a ducted air conditioning system offers comfort and control for both residential and commercial spaces.
What is ducted air conditioning?
A ducted air conditioning system uses a central indoor unit, usually installed in the ceiling or under the floor, to distribute conditioned air through a network of ducts into different rooms or zones. It is controlled via a central thermostat or controller and can be customised for various temperature zones within a building.
Whether you’re fitting out a new build or upgrading your current setup, ducted air conditioning is ideal for those wanting year-round comfort with minimal visual impact.
How does a ducted system differ from other types of AC?
Unlike a split system, which cools or heats a single room with a visible indoor unit, ducted air conditioning is hidden within the structure of your home or commercial space. It delivers air through ceiling or wall vents, creating a cleaner, more streamlined look. If you’re unsure which system is right for your space, check out our post on choosing the right system.
Key components of a ducted air conditioning system
The indoor unit: how it circulates air
- This component is typically located in the roof space or underfloor area. It draws in air, cools or heats it using a heat exchanger, and then sends it through the ductwork.
The outdoor unit: the heart of the system
- Similar to other air conditioners, the outdoor unit contains the compressor and condenser coil. It plays a critical role in the refrigeration cycle, regulating the temperature of the air being sent inside.
The ducts: delivering cool or warm air to every room
- Ducts run from the central indoor unit to various outlets throughout the property. These ducts carry the treated air, allowing even distribution across multiple zones.
How does ducted air conditioning cool or heat your space?
The refrigerant cycle: how it works
- A ducted system uses refrigerant to transfer heat. In cooling mode, it extracts heat from indoor air and expels it outside. In heating mode (via reverse cycle), the process is reversed, heat is drawn from outside and pumped indoors.
Zone control: customising comfort for different areas
- With zoning capabilities, users can control the temperature of individual rooms or areas. This is especially helpful for large homes or commercial premises, offering both energy savings and personalised comfort.
The advantages of ducted air con for both residential and commercial spaces
- Enhanced comfort and control: Set temperatures precisely in each zone.
- Aesthetics: No bulky wall units. Air is delivered via subtle vents.
- Efficiency and cost savings: Especially when used with zoning, ducted systems can be more economical over time.
- Ideal for large spaces: Perfect for multi-room homes or expansive commercial offices.
Is ducted air conditioning suitable for my property?
Ducted air conditioning is ideal for:
- New builds where ductwork can be easily integrated
- Larger homes or commercial properties needing whole-space climate control
- Customers seeking a sleek, unobtrusive air con solution
It may be less suitable for leased business premises, very small homes, two-storey homes, or apartments where a split system could be more cost-effective.
