Sometimes upgrading your home’s heating or cooling system can feel like navigating a maze.

However, with exciting incentives like the “ducted aircon rebate VIC” and schemes comparing “split vs ducted rebate,” it’s worth conducting a thorough analysis before making a purchase.

Therefore, in this blog, we’ll explore three major air conditioning types: ducted, single-split, and multi-split, sometimes called multi-head, and break down which might be best for you, especially under the VEU programme in Victoria.

Here, we’ll also cover pros & cons, cost & rebate implications, efficiency & zoning, suitable house types, and real-world case comparisons.

So, for further details, tag along!

In this blog post:

Victoria’s Air Conditioning System: Ducted, Split, & Multi Split!

Before concluding which system performs best under Victorian Energy Upgrades (VEU), let’s examine how each air conditioning system works, what they are, and their pros & cons.

Let’s start with the ducted system air conditioners:

Ducted Reverse Cycle Air Conditioner Systems

A ducted system uses a central outdoor unit and typically one indoor air handler. The outdoor unit is connected via ducts running through the ceiling or under the floor to distribute air through vents in each room.

Pros of Ducted System

Ducted system ensures whole-home comfort. It is a single system with multiple vents that allow you to heat or cool the entire house more efficiently.
This system doesn’t hamper the aesthetics of your home as the indoor equipment is typically hidden, and vents are discreet.
It allows zoning control, so larger homes can be divided into zones, allowing heating or cooling only specific parts of a house when needed.

Cons of Ducted System

The installation process is more complex as it requires duct cleaning and filter maintenance.
This ducted aircon system costs higher.
If ducts are not well-insulated, there is a chance of inefficiencies and energy losses.
For smaller homes, it might not be suitable and cost-effective.
A higher upfront cost may reduce net savings when your usage is low.

Single Split Systems

Single Split system is a classic reverse-cycle wall-hung indoor unit connected to an outdoor unit, with one indoor head per outdoor compressor. They are typically used for a single room or open area.

Pros of Single Split System

Typically, a simple setup that requires lower installation costs and equipment.
Suitable for smaller homes, individual rooms, or selective upgrades.
They can be controlled independently.

Cons of a Single Split System

If you have multiple rooms, you’ll need multiple splits or outdoor units, which can increase the cost and complexity.
Not as seamless a whole-home comfort as a ducted system.
Multiple visible indoor units on the wall might hamper the building’s aesthetic appeal.

Multi-Split Air Conditioner Systems

Multi-split systems are a hybrid of sorts, featuring one outdoor unit connected to multiple indoor units, typically ranging from 2 to 6 heads.

It’s often used for larger homes where residents want flexible zoning but without complete ductwork.

Pros of Multi-Split Air Conditioner

It strikes a good balance, featuring fewer outdoor units than many single-split systems while still offering flexible room-by-room control.
Often lower in cost than full ducted for whole-home systems.
More efficient than many separate single splits.

Cons of a Multi-Split Air Conditioner

The indoor heads are still visible, and the outdoor unit also remains outside.
Although it is cheaper than a ducted system, it is more expensive than a simple single-split air conditioner.

Are VEU Rebates Worth It? | Cost Comparisons & Rebate Benefits

The VEU programme offers a rebate via VEECs (Victorian Energy Efficiency Certificates) when you upgrade to a high-efficiency reverse-cycle air conditioner or replace an older, inefficient heating and cooling system.

However, there are specific eligibility criteria you must meet to qualify for this air conditioning rebate in Victoria. Those are:

Your property must be more than two years old and located in Victoria.
The product or model must be VEU-approved.
The installation must be performed by a VEU-accredited provider.
For tenants who want to upgrade their system, they must obtain their landlord’s consent.

Typical rebate amounts: How Much Can You Really Save?

If you are in Victoria and planning to upgrade your air conditioner, the VEU rebate program can undoubtedly help you save big.

However, remember that under the VEU program, whether it’s ducted, split, or multi-split, any of these systems can earn you the same rebate if they meet the energy efficiency standards.

You can save $300–$1,500 on a new split, multi-split, or ducted unit. Accredited installers typically apply the rebate as an upfront discount, making it an easy way to upgrade, reduce energy bills, and stay cool for less.

Here are some recent data about the rebates available for Victorian homes:

If you replace a non-ducted gas heater (3-9 kW) with an efficient room-reverse cycle air conditioner, rebates might be $630 to $1,610.
Similarly, if you replace a ducted gas heater (whole-house) with e.g. 4 split systems (1×8kW + 3×3kW), you’ll get a rebate up to $2,520.
For Multi-split whole-home upgrades, the discount amount is typically around $2,940.
Ducted reverse-cycle upgrades, such as replacing a central electric resistance ducted heater, can qualify for significantly larger rebates, ranging from $5,460 to $7,700 in some cases.

Cost Analysis: What You Pay vs Rebate Value!

Single split: lower upfront installation cost with a decent rebate, but smaller savings.

Multi-split: moderate upfront cost, moderate rebate and good middle ground.

Ducted: highest install cost, but highest possible rebate (especially when replacing very inefficient systems).

So, what’s best under the VEU: ducted, split, or multi-split aircons?

Well, the “split vs ducted rebate” question depends on what you’re replacing. If you already have ducted heating, switching to ducted reverse cycle may offer a strong rebate, but it still entails a significant installation cost.

Whereas if you only need one room or two, single splits make sense in your case. For apartments, small houses, and multiple-room offices, a multi-split system can be your ideal choice.

Factors That Influence the VEU Air Conditioner Rebate

When you search “ducted aircon rebate VIC” or “split vs ducted rebate”, remember that the rebate alone doesn’t tell the full story.

You must also consider installation cost, system sizing, efficiency savings, and long-term running costs. Therefore, your rebate or discounts might differ from those offered in Australia.

Here are the factors that influence the rebate amount:

What you are replacing matters. For instance, upgrading a gas ducted system, a gas space heater, or switching to smart LED lighting each qualifies for a different rebate value.
The size of the new system is crucial for the rebate. Remember, bigger systems mean more certificates.
Efficiency of the new system: higher-rated units receive a higher rebate.
Must use an accredited installer and the eligible product list.

Maximising Aircon Efficiency| Power of Zoning & Maintenance

When it comes to energy efficiency, multi-split systems can often deliver lower annual energy costs than ducted systems in certain scenarios.

For example, one guide shows that a standard multi-split system costs around $63 per year to run, while a high-efficiency model can be as low as $40 per year.

In comparison, a standard non-zoned ducted system costs approximately $79 per year, while a high-efficiency ducted system costs around $55 per year.

Ducted systems can lose efficiency if the ductwork is poorly insulated or if there are leaks in the ducts. On the other hand, split and multi-split systems allow you to heat or cool only the rooms you actually use, which makes them more efficient for selective room use.

Zoning

Ducted: Can be zoned to separate upstairs and downstairs, but this requires more equipment and smart controls, which adds cost and complexity.
In Multi-split, each indoor head is effectively its own zone, making it great for families with different preferences.
A single split provides control for only one room. They are simple, but lack whole-home zoning.

Maintenance

In a ducted system, regular maintenance includes checking ducts, cleaning filters, the indoor handler, and the outdoor unit.
If the ductwork is hidden in the ceiling or walls, repairs or cleaning can be more difficult.
In a split or multi-split system, each head needs filter cleaning, and the outdoor unit needs maintenance. Multi-split is still simpler duct-wise.
Ducted, Split or Multi-split, every system requires regular servicing every 1-2 years to help maintain optimal efficiency.

Which System Works Best for Your Victorian House?

Here’s a breakdown by house type, along with a real-life case scenario.

Budget tight or small area to upgrade? Go with a Single Split system.

If the house is modest in size, with 1-2 bedrooms, and you only need to target one main living area or bedroom, a single split is a cost-effective option.
Though the VEU rebate is lower, the installation cost is too, making it worth it.

Medium-Sized Home

If you want flexibility and cover multiple rooms but not the whole house, go with a multi-split air conditioning system:

If you want whole-home coverage with 3-4 bedrooms, but don’t have extensive ductwork or don’t want the cost of full ducted coverage.
A multi-split system with 3-4 indoor heads will provide a good balance of cost, comfort, zoning, and rebate.
Especially good if each room needs its own control.

Large Homes or Multi-level Houses

Consider installing a Ducted System if you desire whole-home comfort.

If you already have ductwork, or if you want a seamless, hidden system with vents in every room.
If your installation cost is justified and you want a single central control.

Under the VEU scheme, you may be eligible for the highest rebate if you replace an extremely inefficient system, such as an old electric resistance or ducted gas system, with a high-efficiency ducted reverse cycle.

To wrap up

Choosing between ducted, single split and multi-split under the VEU air conditioner rebate scheme in Victoria doesn’t have a one-size-fits-all answer. It varies from home to home.

However, what’s important is that you must weigh the upfront installation cost, rebate size, running efficiency, comfort, and how you live in your home before upgrading your system.

For some, the “ducted aircon rebate VIC” looks very attractive, and in other cases, the split system rebate can be more beneficial, especially for smaller homes replacing inefficient systems.

So, if you’re struggling to figure out which air conditioning system is best under the VEU program or which one offers the biggest savings, let Cyangery’s team of experts help you make the right choice.

Happy Monday everyone!

Four offshore wind projects have secured preliminary injunctions blocking the Trump administration’s stop-work order.

Dominion Energy’s Coastal Virginia Offshore Wind.

Avangrid’s Vineyard Wind 1.

Equinor’s Empire Wind.

And Ørsted’s Revolution Wind.

All four argued they were at critical stages of construction.

The courts agreed.

Work has resumed.

A fifth project… Ørsted’s Sunrise Wind… has a hearing scheduled for today.

Now… within days of getting back to work… milestones are being reached.

Dominion Energy reported seventy-one percent completion on Coastal Virginia.

The first turbine… installed in January.

The Charybdis… America’s only U.S.-flagged wind turbine installation vessel… is finally at work. Fifty-four towers, thirty nacelles, and twenty-six blade sets now staged at Portsmouth Marine Terminal. The third offshore substation has arrived.

But here is where the numbers tell the real story.

The month-long delay fighting the Bureau of Ocean Energy Management?

Two hundred twenty-eight million dollars.

New tariffs?

Another five hundred eighty million.

The project budget now stands at eleven-point-five billion dollars.

Nine-point-three billion already invested by end of 2025.

Dominion and partner Stonepeak are sharing the cost.

Dominion insists offshore wind remains the fastest and most economical way to deliver nearly three gigawatts to Virginia’s grid.

A grid that powers military installations… naval shipbuilding… and America’s growing AI and cyber capabilities.

First power expected this quarter.

Full completion… now pushed to early 2027.

Up in New England… Vineyard Wind 1 also resumed work.

The sixty-second and final turbine tower shipped from New Bedford this week.

Ten blade sets remain at the staging site.

The installation vessel is scheduled to depart by end of March.

The turbines are going up.

But eight hundred eight million dollars in delays and tariffs…

That is a price the entire industry is watching.

═══ Scotland Waits on Ming Yang Decision ═══

In Scotland… a decision that could reshape European supply chains… hangs in the balance.

Chinese manufacturer Ming Yang wants to build the UK’s largest wind turbine manufacturing facility.

The site… Ardersier… near Inverness. The investment… one-point-five billion pounds.

The jobs… fifteen hundred.

Trade Minister Chris Bryant says the government must weigh security.

Critical national infrastructure must be safe and secure.

Scotland’s First Minister John Swinney is losing patience.

He told reporters this week the decision has taken too long.

He called it pivotal to Scotland’s renewable energy potential…

and a crucial component of the nation’s just transition.

Meanwhile… Prime Minister Keir Starmer met with President Xi Jinping in Beijing this week.

He spoke of building a more sophisticated relationship between the two nations.

Whisky tariffs… halved to five percent.

Wind turbine factories?

Still under review.

Bryant says they want a steady, eyes-wide-open relationship with China.

Drive up trade where possible.

Challenge where necessary.

But no flip-flopping.

For now… Scotland waits.

And so does the UK supply chain.

═══ Seaway 7 Lands Gennaker Contract ═══

In the German Baltic Sea… a major contract award.

Seaway 7, part of the Subsea 7 Group, will transport and install sixty-three monopiles and transition pieces for the Gennaker offshore wind farm.

The contract value… one hundred fifty to three hundred million dollars.

Subsea 7 calls it substantial.

The client is Skyborn Renewables… a portfolio company of BlackRock’s Global Infrastructure Partners.

Nine hundred seventy-six megawatts of capacity.

Sixty-three Siemens Gamesa turbines.

Four terawatt-hours of annual generation.

Enough to power roughly one million German homes.

Seaway 7’s work begins next year.

═══ Taiwan’s Fengmiao Hits Milestone ═══

In Taiwan… Copenhagen Infrastructure Partners completed the first batch of jacket foundations for the Fengmiao offshore wind farm.

Five hundred megawatts.

On schedule for late 2027 completion.

Offshore installation begins later this year.

The jackets were built by Century Wind Power… a local Taiwanese supplier.

CIP called it a sign of strong execution capabilities and proof they can deliver large-scale, complex energy projects.

But they are not stopping there.

Fengmiao 2… six hundred megawatts… is already in development.

Taiwan is aiming for a major boost in large-scale renewable energy by 2030.

And that is the state of the wind industry for February 2, 2026

It’s probably a bit too soon to have useable statistics on this subject, but it’s certainly not too early to apply some common sense.

There are at two factors at play here:

1) America is broadly regarded as a rogue country. Do you want to visit North Korea? Do Canadians want to spend money in a country that wants to annex them?

2) America is now understood to be unsafe. Do you want to visit Palestine? Ukraine? Iran?

Instead of reacting to the next power bill shock, many Australian businesses are starting to think forward.

Every day, more and more Australian companies are asking a simple question we all seek an answer to: How can we reduce energy costs without compromising performance?

Well, for many, the answer lies in commercial solar power, and Cyanergy is one of the Australian companies helping businesses take that step with confidence.

With hands-on experience delivering commercial solar solutions across a wide range of industries, from farms and sporting clubs to breweries and large manufacturing facilities, Cyanergy’s real-world projects demonstrate how tailored solar systems can transform energy usage and significantly reduce operating expenses.

In this blog, we’ll explore what commercial solar power is, why it matters today, and how Cyanergy’s real-world case studies illuminate the path to a cleaner, more profitable energy future, both financially and environmentally

Let’s get into it!

In this blog post:

What Are Commercial Solar Solutions? |Why does this matter?

Solar solutions for commercial applications are photovoltaic (PV) systems designed to meet the energy needs of businesses, large facilities, and organizations. This system often consumes much more power than residential households.

Commercial solar systems typically include:

Solar PV panels that capture sunlight and convert it to electricity
Inverters and electrical integration are used to convert DC to usable AC power
Monitoring and performance systems are installed to track energy generation
Optional battery storage to support energy autonomy and peak demand management

Unlike residential solar, commercial systems are scaled to handle larger loads and are often optimized for financial return, corporate sustainability goals, and energy independence.

Why Australian Businesses Are Turning to Solar Now?

Throughout the world, many companies are adopting solar power for several compelling reasons. It is already proven
that solar can:

Reduce Operational Costs

Electricity prices are volatile and often increasing worldwide. Incorporating a solar panel helps businesses lock
in
energy cost savings by
producing electricity on-site rather than relying exclusively on grid power.

Strong Financial Returns

Commercial solar systems can pay back their investment in just a few years, far shorter than the 25 to 30 years
the
panels last. This ultimately means, after that, you are left with decades of essentially free electricity.

Sustainability and Brand Value

Customers, employees, and stakeholders increasingly value organizations that visibly commit to environmental
responsibility.

Energy Security

Generating power locally reduces reliance on external sources and grid outages, a huge advantage for businesses
with
continuous operations.

This mix of economic, environmental, and operational benefits makes commercial solar a smart choice for
forward-looking organizations and commercial
property
owners.

4 Proven Solutions Through Real Case Studies by Cyanergy

To understand how these benefits play out in real situations, let’s dive into several commercial solar projects executed by Cyanergy. These case studies show diverse applications of solar power and tangible outcomes for different kinds of businesses.

1. Kew Golf Club (VIC): Sporting Facility Goes Solar

At a local golf club that relied on consistent electricity for lighting, clubhouse operations, and course facilities, Cyanergy installed an 88 kW commercial solar system to reduce costs.

Key Results

Payback period: around 63 months (5 years)
Annual savings: $26,165, a 50% drop in electricity costs
Energy generated per year: 141 MWh

This project demonstrates that not only industrial property but also community-oriented facilities can benefit greatly from solar power.

Beyond cost savings, the golf club also reinforced its commitment to sustainability, attracting eco-conscious members and reducing its carbon footprint.

Why This Matters?

Solar is not limited to manufacturing or heavy industry. In Australia, many Sports clubs, community centres, and similar facilities often have high energy use during peak daylight hours, which can be supported by solar.

2. Sparacino Farms: Where Agriculture Meets Solar Innovation!

Whether for irrigation, cooling, processing, or storage, agricultural operations have faced rising energy costs for a long time.

Similarly, Sparacino Farm was suffering from high electricity costs. For this family-run farm, Cyanergy implemented a 99.76 kW solar system that revolutionised their energy expenses.

Project Highlights

Electricity cost dropped: from $48,000 to $12,000 per year
Monthly savings: roughly $3,000
Payback period: 30 months (2.5 years)
Annual clean energy production: 87 MWh

This dramatic turnaround showcases how rural and agricultural businesses can achieve some of the fastest returns on solar investments.

In environments where a roof, sunlight, or a shed space is available, solar becomes both a strategic and practical choice.

The Sparacino farms example proves that solar isn’t just an environmental sustainability, it’s a core business decision that can significantly improve margins.

3. Philter Brewing: Crafting Sustainability

Sustainability often aligns naturally with brand identity, and for Philter Brewing, this was a perfect match.

With the help of Cyanergy, the brand installed an 86 kW system to slash power costs and support green operations.

Project Impact

Annual energy generated: 99 MWh
Annual savings: $29,130, cutting electricity costs from $81,900 to $52,770
Payback period: 45 months (3.75 years)

The brewery not only reduced operating expenses but also strengthened its reputation as an environmentally conscious brand, a powerful differentiator in a competitive market.

4. Uniplas Mouldings International: Heavy Industry Solar Success

In one of Cyanergy’s most impactful case studies, a large industrial manufacturer significantly transformed its energy profile with solar. And that’s Uniplas Mouldings International!

Project Features

Total installed solar: 490 kW, executed in staged phases
Timeline: Stage 1 (200 kW) completed in just 4 weeks
Subsidy optimisation: Accessed three sets of government incentives
Payback period: as short as 37 months
Annual generation: 752 MWh
Energy cost savings: Lowered from $647,000 to $456,000 per year

Big industrial energy users can unlock dramatic operational savings with solar, saving hundreds of thousands of dollars a year while achieving rapid ROI that justifies investment sooner, without delay.

Beyond Case Studies: Cyanergy’s Approach to Commercial Solar

Across all these projects, Cyanergy’s methodology shares some common themes that contribute to success:

1. Customized System Design

We all know that no two energy profiles are identical, whether it’s a golf club or a manufacturing plant.

At Cyanergy, we design systems tailored to the business’s actual energy usage, site orientation, and financial goals. So you don’t have to worry about adding a solar solution.

2. Financial Optimization

From government incentives to financial investment planning, Cyanergy helps businesses structure their solar projects to reduce upfront costs and improve payback timelines.

3. End-to-End After-Sale Support

Proper solar implementation requires more than panels; it requires site assessment, design, installation coordination, monitoring, and performance guarantee.

At Cyanergy, we support clients at every step, from early energy audits to post-installation support.

4. Monitoring and Reporting

Tracking system performance and energy generation ensures ongoing optimization and confidence in the investment.

Our real-time monitoring tools empower business owners to understand exactly how solar contributes to their bottom line.

The Transformative Role of Solar in Business Strategy

The benefits of commercial solar extend far beyond the energy generated or the energy cost that’s reduced. Overall, solar is a strategic business asset that impacts:

Profitability: Lower operating costs mean more available working capital, whether for reinvestment, dividends, or growth initiatives.

Resilience: Energy independence provides a hedge against market volatility in electricity pricing.

Sustainability Credentials: Solar investments signal that your organization is serious about environmental stewardship, which is crucial to investors, customers, and regulators alike.

Employee and Community Engagement: A company that commits to clean energy signals a long-term vision, strengthening morale and community trust.

Takeaway Thoughts

Cyanergy’s real case studies show how businesses from farms to breweries to industrial giants have harnessed solar to cut costs, stabilize operations, and enhance sustainability.

Whether your organization is exploring its first solar project or looking to scale existing efforts, the data is clear: smart solar investment delivers measurable ROI and long-term value.

As energy dynamics continue to evolve, solar power will become increasingly relevant, and companies that act now will secure economic and environmental advantages for years to come.
