Ducted reverse cycle is the system people picture when they imagine a truly comfortable home: every room the right temperature, summer and winter, with nothing on show but a few slim vents in the ceiling. It is also the biggest heating and cooling decision most Melbourne homeowners make, so it pays to understand what you are buying and what it costs before you commit.
This guide walks through how a ducted reverse cycle system works, what it costs to install in Melbourne, how zoning keeps running costs sensible, and how it compares to split systems. We design and install these systems across Melbourne, so the advice here is exactly what we would tell you on site.
A ducted reverse cycle system heats and cools your whole home from one hidden unit, delivering air through ducts to zoned vents in each room. in Melbourne, expect roughly $8,000 to $25,000 installed depending on home size and zones, with most family homes around $11,000 to $16,000. It works in any weather, and because it heats too, the Victorian Energy Upgrades rebate can help when you are replacing an old heater.
How ducted reverse cycle works
The clever part of a ducted system is that almost all of it is hidden. One outdoor unit and one indoor fan coil do the work, and a network of insulated ducts carries the conditioned air to vents in each room. You set the temperature, choose which zones are running, and the system does the rest.
What you actually get
Unlike a wall-mounted split system, a ducted setup keeps the hardware out of sight. The indoor unit tucks into your roof space or under the floor, the ducting runs through the cavity, and all you see in your living space are neat vents and a wall controller.
That clean look is a big part of the appeal, especially in newer homes and renovations. You get whole-home comfort without a head on the wall of every room. See our reverse cycle ducted page for the systems we install.
What ducted reverse cycle costs in Melbourne
Ducted is a whole-home system, so it is a bigger investment than a single split. Treat these as ballpark ranges for a quality installed system rather than a fixed quote. The number that matters most is the one you get after an on-site assessment, because two homes of the same size can differ a lot once roof access and zoning are considered.
| Home | Typical zones | Installed cost |
|---|---|---|
| Small home, 2 to 3 rooms | 2 to 3 zones | $8,000 to $12,000 |
| Standard family home | 3 to 4 zones | $11,000 to $16,000 |
| Large or two-storey home | 4 to 6 zones | $16,000 to $25,000+ |
What drives the cost
If two quotes come back different, these are usually the reasons. Understanding them helps you compare like for like.
Zoning: comfort where you want it
Zoning is what turns a ducted system from a power-hungry box into a genuinely efficient one. By splitting the home into areas you can control separately, you only heat or cool the rooms in use, which is where most of the saving comes from.
A common Melbourne setup runs the living zones through the day and the bedroom zone overnight. Add a smart controller and you can manage it all from your phone, room by room, without ever touching the rooms you are not using.
Ducted vs split systems: which is right for you?
Both are refrigerated reverse cycle, so both heat and cool. The choice is really about how much of your home you want to condition and how you want it to look.
Choose ducted if
You want the whole home comfortable with a clean, hidden finish and full zoning, and you have the roof or subfloor space for it.
Choose split if
You only need one or two rooms done, or you want the lowest upfront cost for a single living area or bedroom.
Choose multi-head if
You want several specific rooms controlled independently from one outdoor unit. Our multi-head guide covers it.

Rebates and running costs
Because a reverse cycle system heats as well as cools, it can qualify for support under the Victorian Energy Upgrades program, particularly when it replaces an old gas or electric heater. On running costs, reverse cycle is one of the most efficient ways to heat, and good zoning keeps the cooling side sensible too. Our guide on running reverse cycle in Victoria runs through the numbers.
What this means for Melbourne homes
Melbourne’s climate is a strong fit for ducted reverse cycle. Our summers can throw hot, dry days and the odd humid one, and refrigerated cooling handles both without missing a beat. Then the same system carries you through a cold Melbourne winter as efficient heating. For a family home that wants one tidy system for the whole year, it is hard to beat. Check our areas we service to confirm we cover your suburb.
Brand choice matters for ducted too. See our Daikin, ActronAir and Mitsubishi Electric pages for indicative installed prices, or compare every option on our air conditioning brands guide.
Frequently asked questions
How much does ducted reverse cycle air conditioning cost in Melbourne?
As a rough guide for a quality installed system, ducted reverse cycle in Melbourne runs from about $8,000 for a small home with a few zones up to $25,000 or more for a large two-storey home with many zones. Most family homes land somewhere between $11,000 and $16,000. Your home size, the number of zones, system capacity and roof access all move the figure, so a free on-site quote is the only way to get an accurate price.
Does ducted reverse cycle both heat and cool?
Yes. A reverse cycle system cools your whole home in summer and runs the same process in reverse to heat it in winter, all from one ducted system hidden in the roof or under the floor. That year-round capability is the main reason so many Melbourne homes choose it over cooling-only options.
What is zoning and do I need it?
Zoning splits your home into areas that you can heat or cool independently, so you are not paying to condition empty rooms. For example, you might run the living areas during the day and the bedrooms at night. Most Melbourne homes benefit from at least a few zones, and it is one of the biggest levers for keeping running costs down.
Ducted reverse cycle or split systems: which is better?
It depends on how much of the home you want to condition. Ducted reverse cycle is the neatest way to cool and heat the whole home, with only discreet vents visible and full zoning. Individual split systems, or a multi-head split system, can be more cost-effective when you only need a few specific rooms done. If you want whole-home comfort with a clean finish, ducted usually wins.
Is ducted reverse cycle expensive to run?
It uses more electricity than a single split system because it conditions more space, but it is efficient per room and reverse cycle is one of the cheapest ways to heat a home. Good zoning, an efficient inverter unit and solar all bring running costs down. Running only the zones you are using is the single biggest saving.
Can ducted reverse cycle be added to an existing home?
in most cases, yes, provided there is enough roof or subfloor space for the indoor unit and ducting. Single-storey homes with accessible roof space are the most straightforward. Double-storey homes and some older builds need a more tailored design, which we assess on site before quoting.
Are there rebates for ducted reverse cycle in Victoria?
Efficient reverse cycle systems can qualify for support under the Victorian Energy Upgrades program, especially when you are replacing an old gas or electric heater. The rebate amount depends on the system and your situation. We can talk you through eligibility and handle the paperwork as part of the job.
How long does ducted reverse cycle installation take?
A typical single-storey installation is often completed in one to two days. Larger homes, double-storey builds or jobs that need extra ducting can take longer. We give you a clear timeframe with your quote so you know what to expect.
