Licensed refrigeration technician, correct system design, professional installation from start to finish.

What Is Ducted Air Conditioning?
Ducted air conditioning uses a central unit installed in the roof space to distribute conditioned air through a network of ducts and ceiling vents throughout the home. Unlike split systems where the indoor unit is visible on the wall, a ducted system is almost entirely hidden, with only the vents visible in each room.
One outdoor compressor connects to the central indoor unit, which pushes conditioned air through the ductwork to every zone in the property. The result is consistent, whole-home heating and cooling with a finish that looks like it was always part of the house.
All modern reverse cycle ducted systems heat and cool, making them a practical year-round solution for Melbourne’s variable climate.
Zoned Ducted Air Conditioning Melbourne
Zoning is one of the biggest advantages of a modern ducted system and one of the most important things to get right during the design phase.
How Zoning Works
Motorised dampers inside the ductwork open and close to direct airflow to selected zones throughout the home. Each zone is controlled independently via a central wall controller or, on newer systems, through a smartphone app. Different temperatures in different areas, rooms switched off when not in use, schedules set to suit your daily routine.
Why Zoning Matters in Melbourne
Melbourne’s climate means you’re running your system for heating in winter and cooling in summer across a home that often has very different temperature demands in different areas throughout the day. A well-designed zoning setup lets you condition only the areas you’re actually using, reducing running costs significantly without compromising comfort anywhere in the home.
We design every ducted installation with zoning built in from the start, making sure your system gives you maximum flexibility and efficiency from day one.
Ducted Air Conditioning for New Builds and Renovations
Ducted air conditioning is most cost-effectively installed during the construction or renovation phase of a project before walls and ceilings are closed in. Running ductwork through an open roof space during a build is straightforward. Retrofitting ductwork into a finished home is more complex and more expensive.
Pergz Air works with Melbourne builders, architects, and homeowners on new residential builds and renovations, coordinating with other trades, working to the construction program, and making sure the system is designed and installed correctly from the ground up.
If you’re planning a new build or renovation in Melbourne and ducted air conditioning is on the list, get us involved early. It makes the whole process simpler and gives you more flexibility in how the system is designed.
Replacing an Existing Ducted System in Melbourne
If your existing ducted system is aging, inefficient, or no longer keeping up with your home’s needs, replacing it with a modern unit can make a significant difference to comfort and running costs. Newer ducted systems are far more energy efficient than older models and offer features like zoning, app control, and variable speed compressors that older systems simply don’t have.
We assess your existing ductwork to determine whether it can be reused or needs replacing, advise on the right replacement unit for your Melbourne property, and manage the full replacement from removal through to commissioning of the new system.
Is Ducted Air Conditioning Right for Your Melbourne Home?
Ducted air conditioning is the right choice when you want climate control across your entire Melbourne home and you want it to look seamless. It’s a premium installation that adds genuine value to a property and delivers a level of comfort and consistency that split systems can’t match across a whole home.
Ducted systems suit:
- Melbourne homes wanting whole-home heating and cooling from one system
- New builds and major renovations where ductwork can be run during construction
- Properties where aesthetics matter and wall-mounted units aren’t desirable
- Larger Melbourne homes with multiple bedrooms, living areas, and open plan spaces
- Homeowners looking to add long-term value to their property
- Commercial premises requiring consistent climate control throughout
If whole-home coverage isn’t the goal or budget is the primary consideration, a multi head split system may be the more practical fit. We’ll walk you through both options honestly before you decide.
Our Ducted Installation Process

Testing and Handover
Every zone is tested in heating and cooling mode before we finish. We walk you through the controller, explain how to set zones and schedules, and make sure you’re confident operating the system before we leave.

Installation
We manage the full installation from start to finish. Central indoor unit installed in the roof space, ductwork run and connected throughout the property, vents and grilles installed in each room, outdoor compressor mounted and connected, and the full system wired and commissioned before handover.

Melbourne Property Assessment
We carry out a thorough assessment of your property before we quote. That includes measuring the spaces to be conditioned, assessing the roof space for the central unit and ductwork, determining the best vent locations in each room, and identifying the right position for the outdoor compressor.

System Design and Sizing
Getting a ducted system sized correctly is critical. An undersized system runs constantly and struggles to reach temperature. An oversized system short cycles and wears out prematurely.
We calculate the right capacity based on total floor area, ceiling height, insulation levels, window size and orientation, sun exposure across the Melbourne property, and how the home is used day to day. We present our sizing recommendations clearly and explain the reasoning before you commit to anything.
Brands We Install in Melbourne
We supply and install multi head split systems from Daikin, Mitsubishi Electric, Fujitsu, Samsung, LG, Panasonic, and other leading brands trusted by Melbourne homeowners. We’ll present the right options for your property and budget during your quote without pushing you toward something you don’t need.

Frequently Asked Questions
Can each room be set to a different temperature?
Yes. Every indoor unit operates independently with its own controller. Different temperatures, modes, and fan speeds in every room, or switch zones off entirely while others keep running.
How long does installation take?
A two or three head system typically takes a full day. Larger installations may take longer. We'll give you a realistic timeframe when we quote.
Is it cheaper than multiple single head systems?
Generally yes, particularly when connecting three or more rooms. One outdoor unit instead of multiple compressors reduces equipment cost and installation complexity. We'll give you a clear comparison during your quote.
Do multi head systems work in Melbourne winters?
Yes. All modern reverse cycle systems heat and cool, handling Melbourne's cold winters and hot summers in a single unit.
How much does multi head installation cost in Melbourne?
It depends on the number of indoor units, brands selected, and installation complexity. Get in touch for a free, no-obligation quote tailored to your Melbourne property.
How often should the system be serviced?
Once a year at minimum to keep all units running efficiently and maintain manufacturer warranty. We carry out split system servicing across Melbourne if you need ongoing maintenance support.
