Converting Evaporative Cooling to Refrigerated AC Costs

One of the most frequent questions homeowners in Melbourne ask revolves around transitioning from evaporative cooling systems. This traditional method of cooling has been prevalent for many years; however, it faces significant challenges in humid conditions. It necessitates open windows to operate effectively and fails to provide any warmth during the chilly winter months that Melbourne experiences.

Upgrading to a refrigerated reverse cycle ducted air conditioning system effectively addresses these issues. With this advanced system, you will enjoy exceptional cooling even during the most humid summer days in Melbourne, efficient heating throughout the winter season, and the ability to completely seal your home. This allows for effortless control of indoor temperatures—all facilitated by a single, integrated unit.

This extensive guide outlines the transition process, estimated costs, and essential factors to consider before making your decision. Contact us today to discuss your evaporative changeover costs and discover your eligibility for the VEU rebate.

What Are the Essential Steps for Transitioning From Evaporative Cooling to Refrigerated Air Conditioning?

The transition from one cooling system to another can often be more intricate than homeowners initially anticipate. Understanding the components involved in this transition will empower you to make a well-informed decision regarding your home’s climate control options.

Evaporative cooling units are generally installed on the roof and utilise a different duct system compared to refrigerated air conditioning. The existing ducts for evaporative cooling are larger and uninsulated, making them incompatible with a new refrigerated setup. Therefore, the changeover process comprises several crucial steps:

• Removing the existing evaporative unit from the roof and securely sealing the area where it was positioned.
• Taking out the current evaporative ductwork to facilitate the installation of new components.
• Installing new insulated ductwork specifically designed for refrigerated air conditioning systems.
• Positioning both the outdoor and indoor units required for the new reverse cycle system.
• Completing all necessary electrical work to support the new setup.

Typically, this entire operation requires a full day for completion; however, larger homes may necessitate up to two days. The result is a fully functional system rather than just a temporary fix on the existing infrastructure.

Why Do Many Homes in Melbourne With Evaporative Cooling Also Feature Gas Heating Systems?

Most homes in Melbourne have been designed with two separate systems: gas ducted heating for the colder winter months and evaporative cooling for the warmer summer months. This dual-system approach has effectively met the unique demands of each season.

If your home matches this description, you will be pleased to know that you can replace both systems with a single, efficient reverse cycle ducted system during one installation. Additionally, since you are removing a gas heating appliance, you become eligible for the Victorian government’s VEU rebate. This rebate directly reduces your installation costs, simplifying the process without the need for extensive paperwork.

The pricing listed below reflects this scenario—replacing both your gas ducted heating and evaporative cooling systems with a new reverse cycle system, inclusive of the VEU rebate.

System Size	Up to	All-in price (incl. VEU rebate & ducting)
12.5KW	6 outlets	From $6,300
16–17KW	10 outlets	From $7,300

The prices mentioned are all-inclusive and encompass every cost—GST, the VEU rebate, removal of old systems, roof patching, and complete installation of new ductwork and grilles. Furthermore, premium systems from reputable brands are available at higher price points. We will guide you through the available options during our comprehensive assessment of your home.

What Are My Options If My Home Only Has Evaporative Cooling and No Gas Heating?

If your home solely relies on evaporative cooling and you wish to maintain that system, we can replace your current unit with a new evaporative system starting from $4,400. Please note that no VEU rebate applies in this case since evaporative cooling operates on electricity, meaning no gas appliance is being removed.

However, if you are considering an upgrade to a refrigerated reverse cycle system—which provides both heating and cooling year-round and performs efficiently even on humid days—we can assist you with that as well. Contact us today, and we’ll explore both options tailored specifically to your home’s needs.

Understanding the VEU Rebate: How Can It Make Your Transition More Affordable?

The Victorian Energy Upgrades (VEU) program offers a rebate when you replace a gas heating appliance with a qualifying premium reverse cycle electric system, whether it be a ducted or split system. This rebate is applied upfront, which means the prices in the table above already reflect its deduction. You will not need to submit separate claims or wait for a payment; we manage all necessary paperwork on your behalf.

To qualify for this rebate, the new system must be rated highly for energy efficiency. You can feel confident knowing that every system installed by Beyond meets this crucial standard.

Why Is Evaporative Cooling Becoming Outdated for Most Homes in Melbourne?

Evaporative cooling systems were initially designed to excel in dry heat conditions. However, Melbourne’s summers have increasingly become more humid, rendering evaporative systems less effective when cooling is most essential. Furthermore, these systems require keeping windows and doors open, which allows dust, pollen, and outdoor air to enter your home, negatively impacting indoor air quality.

In contrast, refrigerated reverse cycle air conditioning operates efficiently, regardless of humidity levels. It allows you to keep your home sealed while maintaining a controlled indoor temperature, and it also provides heating during winter. Many homeowners transitioning to this system often express a wish that they had made the change sooner after experiencing the enhanced comfort and efficiency of their new installation.

If you have solar panels installed, you can power your cooling system using solar energy during the summer months. In winter, this setup assists in keeping your home warm during the day when your solar panels generate the most electricity, optimising your energy usage.

Common Questions Regarding the Transition Process

Why can’t the existing evaporative ducts be utilized in the new system?

The existing evaporative ducts are designed to be larger and lack insulation; they are engineered to handle high volumes of air at low pressure. In contrast, refrigerated systems operate differently and require smaller, insulated ductwork to maintain optimal temperatures during the air distribution process. Reusing the old evaporative ducts would lead to inefficiencies and considerable energy loss. Therefore, installing new ductwork is a critical aspect of the changeover.

What occurs with the roof opening once the evaporative unit is removed?

As part of the installation process, we will patch the roof opening. The old evaporative unit will be removed, the roof opening will be sealed and weatherproofed, and the new refrigerated system’s outdoor unit will be positioned either at ground level or mounted on a wall bracket, rather than remaining on the roof.

Does the new system provide both heating and cooling functionalities?

Absolutely. This dual functionality is one of the primary reasons many homeowners in Melbourne opt for this upgrade. A reverse cycle ducted system is capable of delivering both heating and cooling from the same vents, effectively replacing both gas heating in winter and evaporative cooling in summer with one comprehensive solution.

Am I eligible for the VEU rebate if my home only has evaporative cooling without gas heating?

No, the VEU rebate is specifically available for the removal of gas heating appliances. If your home is exclusively equipped with evaporative cooling and does not have gas ducted heating, you will not qualify for this rebate. However, we can still provide you with a competitive quote for the changeover—just contact us for further information.

How long does the installation process typically require?

In most cases, the changeover process can be completed in a single day; however, larger homes or those with more complex roof configurations might need an additional day for finalisation. We will provide you with an estimated timeline during our assessment of your home to ensure transparency.

Will the new system operate efficiently on humid days when evaporative cooling systems struggle?

Yes, indeed. Refrigerated air conditioning functions by extracting heat from the air inside your home, and its efficiency remains unaffected by humidity levels. In fact, it often performs better on humid days compared to dry conditions, sharply contrasting with the challenges faced by evaporative cooling systems during such weather.

If I have solar panels, will that help lower my running costs?

Absolutely, and significantly so. Summer is the peak production period for solar panels, coinciding with the times when you will be operating your cooling system most heavily. Utilising solar energy to power your air conditioning during the day dramatically reduces your energy expenses. Be sure to inform us about your solar setup when requesting a quote, and we can discuss zoning options that maximise your solar advantages.
