If your evaporative cooler is showing its age, struggling to keep up on sweltering days, or simply needs to be replaced, you have two viable options to consider. You can either replace it with a new evaporative cooling system, or you might want to take this opportunity to upgrade to a more efficient refrigerated reverse cycle air conditioning system that provides heating and cooling throughout the year, ensuring comfort in all seasons.
Let’s explore what each option entails, including the associated costs, so you can make an informed decision for your home.
Explore Option 1: Simple Replacement with a New Evaporative System
If you prefer a straightforward replacement, where your old evaporative system is simply swapped out for a new one, we can facilitate that starting from $4,400 for a new evaporative unit. This option allows for an easy transition with minimal disruption.
The process involves removing the old unit from the roof and installing a new one in its place. If your existing ductwork is in good condition, it can potentially be reused, which significantly reduces the overall cost of the installation.
Be aware that no VEU rebate applies for a like-for-like evaporative replacement since it's already an electric system, meaning there’s no gas appliance being removed from your home.
- Homes situated in drier regions where evaporative cooling is effective
- Homeowners seeking a straightforward, cost-effective replacement
- Scenarios where the existing ductwork is confirmed to be in good condition
Important considerations before making your decision: It’s essential to note that evaporative cooling requires windows and doors to be left open for optimal performance, as it relies on drawing in outside air to cool the interior. During Melbourne's increasingly humid summer months, this method can struggle to maintain a comfortable indoor environment. Moreover, evaporative systems do not provide heating during winter, which means you will still need a separate heating solution. If you find this limitation frustrating, you may want to consider Option 2.
Consider Option 2: Upgrade to a Refrigerated Reverse Cycle Ducted System
If you are ready to move away from evaporative cooling altogether, upgrading to a reverse cycle ducted system offers reliable cooling on Melbourne’s humid days, effective heating throughout winter, and complete control with windows closed — all managed from a single system. This upgrade provides comprehensive climate control for your home.
However, this installation involves more work than a simple like-for-like swap. The ductwork used for evaporative systems cannot be reused for refrigerated systems, as it is larger, uninsulated, and configured differently. Therefore, the changeover includes:
- Removal of the evaporative unit from the roof and patching the area where it was installed (costing $480; you must supply matching tiles)
- Removal of the existing evaporative ductwork
- Installation of new insulated ductwork specifically designed for refrigerated systems
- Installation of both the new outdoor and indoor units for the reverse cycle system
The outcome is a completely new system, rather than a patch job on the old evaporative setup.
Do You Also Have Gas Ducted Heating in Your Home?
If your residence utilises gas ducted heating during winter while relying on evaporative cooling in the summer — this detail is crucial to your decision.
By replacing both systems simultaneously with a single reverse cycle ducted system, you can qualify for the Victorian government’s VEU rebate. This rebate is applied directly to your installation costs, eliminating the need for forms, waiting periods, or cashback claims. We take care of all the paperwork for you.
This approach is the most economical way to transition to an all-electric system in one go. You can remove two outdated systems, install a single new unit that provides both heating and cooling, and benefit from the government rebate that reduces your costs from the outset.
Understand the Pricing for Your New System
| System Size | Up to | All-in price (incl. ducting & GST) |
|---|---|---|
| 12.5KW | 6 outlets | From $6,300 |
| 16–17KW | 10 outlets | From $7,300 |

NOTE: If there’s no gas appliance being removed, the rebate does not apply, but the pricing for the refrigerated changeover still stands as listed above.
Determine Which Option Is Best for Your Home
| New Evaporative System | Refrigerated Reverse Cycle System | |
|---|---|---|
| Upfront cost | From $4,400 | From $6,300 |
| Cools effectively on humid days | No | Yes |
| Heats effectively in winter | No | Yes |
| Windows must be kept open | Yes | No |
| VEU rebate available | No | Only if gas is also removed |
| Ductwork can be reused | Possibly | No – always replaced |
If you live in a consistently dry climate and are satisfied with your evaporative system, Option 1 is a reliable and budget-friendly choice. However, if Melbourne’s unpredictable summers and the need for winter heating are causing you frustration, Option 2 efficiently addresses both challenges in a single installation.
Uncover Why Melbourne Homeowners Are Transitioning Away From Evaporative Cooling
Melbourne’s climate has evolved significantly. Summers have become more humid than in the past, and evaporative cooling, which was designed primarily for hot, dry conditions, struggles during those critical times when you most need relief. As a result, many homeowners are looking for alternatives.
Moreover, the necessity of keeping windows open presents its own challenges. In locations near busy roads, during bushfire seasons, or simply for security reasons, having to leave windows open to operate your cooling system is not an ideal situation for many families.
Another important consideration is the use of gas. Many homes in Melbourne that utilise evaporative cooling also rely on gas ducted heating. As gas prices continue to rise and the Victorian government promotes the switch to all-electric systems, homeowners are increasingly using the replacement of their evaporative system as an opportunity to transition fully to electric heating and cooling, addressing both needs in one fell swoop.
According to statistics from the Victorian government, an average Melbourne home transitioning to an all-electric system can save approximately strong,900 per year without solar, or $2,230 per year when equipped with solar panels.

Answers to Common Questions
Why Can’t I Reuse My Evaporative Ducts for a Refrigerated System?
Evaporative ducts are larger and uninsulated, specifically designed to move high volumes of air at lower pressure. On the other hand, refrigerated systems require smaller, insulated ductwork to effectively maintain the temperature as cool air travels through the roof. Utilizing old evaporative ducts would lead to poor performance and significant energy loss, ultimately affecting your home's comfort.
What Happens to the Hole in the Roof When the Evaporative Unit Is Removed?
We will seal and patch the hole as part of the installation process for $480. The roof opening will be closed and made weatherproof, which is essential for protecting your home. You will need to supply matching roof tiles; our team will provide guidance on what is needed during the assessment of your home. The new refrigerated system’s outdoor unit is typically installed at ground level or attached to a wall bracket rather than being placed on the roof.
Does the New Refrigerated System Heat as Well as Cool?
Absolutely — this is one of the primary reasons why many homeowners in Melbourne choose to make this transition. A reverse cycle ducted system effectively heats and cools through the same vents, providing year-round climate control. If you currently use gas heating in winter and evaporative cooling in summer, this new system will replace both, offering a more efficient solution.
Do I Qualify for the VEU Rebate If I’m Replacing Evaporative Only?
No — the VEU rebate is specifically applicable to the removal of gas heating appliances. A like-for-like replacement of your evaporative system does not qualify for the rebate. However, if your home also features gas ducted heating and you remove both systems simultaneously, the rebate can be applied to the refrigerated reverse cycle installation.
How Long Does the Installation Take?
Typically, a like-for-like replacement of an evaporative system can be completed in a single day. A full changeover to a refrigerated reverse cycle system also usually takes one day, although larger homes may occasionally require two days for completion. We will provide you with a clear timeline during the assessment of your home to ensure you are well-informed.
Will Refrigerated Air Conditioning Work on Humid Melbourne Days When My Evaporative Struggled?
Yes. Refrigerated air conditioning functions by removing heat from the air inside your home, regardless of the outside humidity levels. In fact, it tends to work more efficiently on humid days compared to dry conditions, which is the opposite of how evaporative cooling operates.
I Have Solar Panels — Will That Help With Running Costs?
Absolutely. Summer is the peak season for solar panels to generate energy, which coincides with the times when you are running your cooling system the hardest. By operating your air conditioning on solar power during the day, you can significantly reduce your running costs. When you request a quote, be sure to mention your solar setup, and we can discuss zoning options to maximise your savings.
