What Influences the Cost of Ducted Air Conditioning?
Several factors affect the total cost of a ducted air conditioning system, including the size of your home, the type of system, installation complexity, and energy efficiency ratings.
- System Size and Capacity
- Number of Zones
- Installation Complexity
- Brand and Energy Efficiency
- Additional Features
Ducted air conditioning systems are available in different capacities, measured in kilowatts (kW). The larger your home, the more powerful the system required. A small ducted system (around 10kW) may suit a compact home, while a larger house might need 15kW or more to ensure even temperature distribution.
Zoning allows you to control airflow to specific areas, reducing energy consumption by only cooling or heating rooms in use. The more zones you add, the higher the upfront cost, but zoning can significantly improve long-term efficiency and running costs.
Installation costs vary depending on factors like ceiling space, home layout, and ductwork requirements. A single-storey home with easy roof access typically costs less to install than a multi-storey house, where additional labour and materials are required.
Leading brands offer different models with varying levels of energy efficiency. While high-efficiency units cost more initially, they provide long-term savings on power bills. Systems with inverter technology adjust power output based on demand, reducing energy wastage.
Modern ducted systems come with features like Wi-Fi control, smart thermostats, and motion sensors that help optimise energy use. While these add to the overall cost, they can improve convenience and efficiency.
Typical Costs for Ducted Air Conditioning
The cost of installing ducted air conditioning varies depending on the factors above. Below is a general guide:
- Small home (2–3 bedrooms) – $8,000 to $12,000
- Medium home (3–4 bedrooms) – $10,000 to $14,000
- Large home (4+ bedrooms) – $12,000 to $18,000+
These prices include the unit, ducting, and professional installation. Additional zoning, upgraded controls, or complex installations can increase costs.
Ongoing Running Costs
Running costs depend on factors like system efficiency, insulation quality, and how often you use the system. A well-zoned, energy-efficient ducted system typically costs between $1.50 and $3.50 per hour to run. Using zoning, setting appropriate temperatures, and keeping filters clean can help reduce electricity usage.
Is Ducted Air Conditioning Worth the Investment?
While ducted air conditioning has a higher upfront cost than split systems, it offers benefits such as:
- Whole-home climate control – No need for multiple units.
- Improved energy efficiency – Especially with zoning and inverter technology.
- Discreet design – No bulky indoor units, just sleek ceiling vents.
- Increased property value – A desirable feature for buyers and renters.
If you’re building or renovating, installing a ducted system during construction can reduce costs compared to a retrofit.
