Comfort Across Your Space
The essence of having a comfortable home or workplace lies in having the right heating and cooling system. A ducted air conditioning system provides heating & cooling across multiple rooms, with flexible zoning and smart control capabilities. Having properly designed ductwork and carefully positioned air outlets helps maintain smooth airflow and minimise indoor noise, offering a quieter, more comfortable environment. At Complete Air Systems, we do not just focus on the size of your space but also take into account the use of each room so that we ensure that your ducted air conditioning system is designed and installed in such a way that it will run efficiently. Additionally, if you are planning to upgrade your system or require any repairs or maintenance, our team is available to assist you.
Find the Perfect Ducted Solution
Choosing the right ducted air conditioning system involves more than measuring the size of your property. Our technicians assess your home’s or business premises, room usage, and airflow requirements to recommend a system that meets your heating and cooling needs.
✔️ Size and layout of the premises
✔️ Ceiling and roof space
✔️ Insulation/glazing
✔️ Sunlight and heat
✔️ Room function and zoning
Following the assessment, our expert technicians will recommend the right ducted system capacity and zoning configuration, and outlet placements for your property to ensure efficient airflow and consistent heating and cooling throughout your space.

Cooling and Heating without Wall Mount Units
The ducted system makes it possible to cool and heat the entire house in a single unit
Neat Appearance:
Since the ducts are located either on the ceiling or under the floors of the house, their appearance can only be seen discreetly.
Energy Efficient Zoning:
You can switch off the air conditioning in unoccupied rooms using zone controls, hence reducing your electricity bills.
Quiet Operation:
Well-designed ductwork, correctly positioned outlets, and balanced airflow help minimise indoor noise for a quieter, more comfortable environment.
Increases Your Property Value:
Ducted air conditioning provides heating and cooling throughout your property without the need for multiple wall-mounted units. Their discreet designs and convenience in controlling temperature make your home more appealing to potential buyers, particularly those looking for year-round comfort and advanced technological features.
Perfect Comfort:
The size of the ducted system plays a major role in maintaining a constant temperature in all the rooms.

Terrible organization, got quoted 1 prize and the cost on completion was double, no additional work or parts added. Techs were good but I booked for 1 day service and I received 2 different technician even though I booked for the same day service, and 1 week apart

I had three split systems installed by Complete Air Systems. They were quick, efficient and clean. It was a hard job due to the low roof pitch on my home, but nothing was too much for the team. Happy with thier service and would recommend!

FAQS
The cost depends on your home’s size and layout, the system selected, and the ductwork, zoning, and controls required. These ranges provide a budgeting guide for a basic new ducted reverse-cycle installation.
| Typical Home Size | System Capacity | Typical Installed Price Range |
| Smaller 2-3 bedroom home | 8.5–10 kW | $9,700–$13,200 |
| Standard 3-4 bedroom home | 12–12.5 kW | $11,100–$14,200 |
| Larger 4-bedroom home | 14–16 kW | $12,600–$16,800 |
| Large 4-5 bedroom home | 16–18 kW | $13,200–$17,400 |
| Very large 5+ bedroom home | 20–25 kW | $19,500–$22,600 + |
Prices include GST and represent typical budget ranges for basic installations, including standard ductwork, outlets, zoning and controls for the selected package. Additional outlets or zones, upgraded controls, difficult access and electrical upgrades may increase the price. Bedroom counts are a guide only; we assess your home to confirm sizing and design. Your final quote may be lower or higher and will confirm the scope, inclusions and price.
Standard zoning allows you to switch airflow on or off to different areas of your home, such as bedrooms and living spaces.
Smart zoning offers more control. Depending on the system and controller selected, it can provide adjustable airflow, scheduling, app control, and individual zone temperature sensors. With compatible sensors and controls, the system can automatically adjust airflow to help maintain the selected temperature in each zone.
Individual temperature control isn’t included with every zoning package. We explain the available options when designing your system.
Often, yes—provided the existing ductwork is in good condition and suitable for the replacement system.
We assess its condition, insulation, sizing, and layout, along with the outlets, return air, and zoning components. Reusing suitable components can reduce the installation cost, but damaged, poorly insulated, or incorrectly sized ductwork may need repairs or replacement.
Your quote will clearly identify what we’re retaining and what needs replacing.
A ducted changeover can cost less than a new installation when existing ductwork and other components are suitable for reuse. These ranges provide a budgeting guide for replacing an existing ducted reverse-cycle system.
| Typical Home Size | System Capacity | Typical Installed Price Range |
| Smaller 2-3 bedroom home | 8.5–10 kW | $7,300–$10,300 |
| Standard 3-4 bedroom home | 12–12.5 kW | $8,600–$10,800 |
| Larger 4 bedroom home | 14–16 kW | $9,000–$12,400 |
| Large 4-5 bedroom home | 16–18 kW | $9,400–$14,600 |
| Very large 5+ bedroom home | 20–25 kW | $15,800–$17,400 + |
Prices include GST and represent typical budget ranges for basic changeovers with suitable access and reuse of compatible ductwork, outlets and zoning components. Duct repairs or replacement, control upgrades, electrical upgrades and building alterations may increase the price. These ranges do not apply to evaporative-to-reverse-cycle conversions. Your final quote may be lower or higher following assessment and will confirm the scope, inclusions and price.
Yes. Ducted reverse-cycle air conditioning provides both heating and cooling, making it an option for year-round comfort.
This is generally a new system installation rather than a straightforward equipment changeover. Evaporative ductwork and outlets are generally unsuitable for reuse, so we assess the roof space and design new ductwork, outlets, return air and zoning for your home.
We also identify any roof repairs, ceiling patching or electrical work required and clarify what is included in your quote.
Use zoning to condition the areas you’re using, choose a comfortable, moderate temperature, and close external doors and windows. Blinds and curtains can also help reduce heat entering through windows.
Keep the return air filter clean and ensure return air grilles remain unobstructed. Follow the operating guidance for your system—closing too many zones can restrict airflow, and some installations require a minimum number of zones to remain open.
Use timers or scheduling to suit your routine, and switch the system off when the home won’t be occupied for an extended period.
For a regularly used home system, we generally recommend professional servicing annually. Heavily used systems may need more frequent attention. If airflow or performance drops, water leaks or unusual noises develop, arrange an inspection rather than waiting for the next scheduled service. Dusty environments and homes with pets may require more frequent cleaning.
