What Determines the Cost of Ducted Air Conditioning?
Home Size and Layout
The size and layout of your home are among the biggest cost determinants. A larger home requires a more powerful air conditioning unit to cool every room effectively.
If your home has multiple levels or an unconventional design, additional ductwork and zoning might be required, increasing both equipment and installation costs.
For example, a small single-storey home (100–150m²) may need a 10kW system, whereas a larger two-storey home (250m²+) might require a 20kW system. The more powerful the system, the higher the price.
Type and Brand of System
Not all ducted air conditioning systems are created equal. Premium brands like Daikin, Mitsubishi Electric, and Fujitsu often come with higher price tags due to their reliability, energy efficiency, and advanced features.
Entry-level brands offer budget-friendly solutions but may lack durability or efficiency.
Mid-range and premium brands tend to have better warranties, quieter operation, and improved temperature control, making them a worthwhile investment for long-term savings.
Installation Complexity
The complexity of your installation plays a huge role in the final price. Several factors can make the job more labour-intensive:
- Roof space availability – Limited roof space or tight areas may require extra work.
- Existing ductwork – Homes without pre-installed ducts will have higher costs due to additional materials and labour.
- Electrical upgrades – If your current electrical system isn’t sufficient, rewiring or upgrades may be needed, adding to the cost.
Homes with easy access to the ceiling cavity and existing ductwork generally have lower installation costs, whereas properties that need structural modifications or additional components will see a higher installation price.

Energy Efficiency and Star Ratings
Energy efficiency is an important consideration when choosing a system. While higher-rated units have a higher upfront cost, they consume less electricity and reduce long-term running costs.
Ducted systems are rated using the Zoned Energy Rating Label (ZERL) in Australia.
A system with a higher star rating may cost $500–$1,000 more than a lower-rated model but can save you hundreds of dollars annually on energy bills.
Number of Zones
Zoning allows you to control which areas of your home receive cooling, improving efficiency and lowering energy costs. However, adding zones increases the upfront price due to the need for additional dampers, controllers, and installation work.
- Single-zone systems cool the entire house at once and are cheaper to install.
- Multi-zone systems let you cool specific rooms or areas, reducing electricity use but increasing installation costs.
A basic two-zone system may add around $500–$1,000, while a more advanced six-zone system can add $2,000 or more to the total cost.
Additional Features and Smart Controls
Modern ducted air conditioning systems come with various optional features that enhance comfort and convenience but also add to the cost.
- Wi-Fi and smart controls – Allow remote operation via smartphone apps. ($200–$500 extra)
- Air purification and allergen filters – Improve air quality but increase unit costs. ($300–$800 extra)
- Motion sensors – Automatically adjust settings when a room is unoccupied, saving energy. ($150–$400 extra)
While these features may increase the initial cost, they can provide long-term benefits in energy savings and indoor air quality.
Labour and Installation Costs
Installation costs vary based on the experience of the installer and the complexity of the job. A professional installer with a strong reputation may charge more, but their expertise ensures the system runs efficiently and lasts longer.
Expect to pay between $2,000 and $6,000 for installation, depending on:
- The difficulty of installation
- Whether electrical work is required
- The number of zones being set up
Choosing a licensed and experienced installer can prevent costly mistakes and ensure your system performs at its best.
Running Costs and Maintenance
The ducted air conditioning cost doesn’t end after installation. Running costs depend on system efficiency, electricity rates, and how frequently you use it.
On average, running a ducted air conditioner costs between $300 and $600 per year, but this varies based on the system size and energy efficiency.
Regular maintenance is essential to keep the system performing optimally. Professional servicing costs around $150–$300 per visit, typically recommended once or twice a year.
Neglecting maintenance can lead to higher energy bills and expensive repairs in the long run.

An oversized system wastes energy, while an undersized unit struggles to maintain a comfortable temperature. To ensure efficiency, work with a professional to choose the right system size based on your home’s square meterage and insulation.
Use Zoning to Control Energy Usage
Installing zoning controls allows you to cool or heat only the rooms you’re using. This can cut energy costs by up to 30%, as the system won’t be running at full capacity for unoccupied areas.
Take Advantage of Off-Peak Electricity Rates
Some electricity providers offer lower rates during off-peak hours. Running your system during these times can help reduce power costs. Check with your energy provider for available time-of-use tariffs.
Keep Up with Regular Maintenance
Routine servicing prevents costly repairs and keeps your system running efficiently. Key maintenance tasks include:
- Cleaning or replacing air filters every 3–6 months
- Checking for leaks or duct damage annually
- Scheduling a professional service once a year to ensure optimal performance
