Ducted Gas Heating Installation Melbourne: What to Expect

Wed, 06 May 2026 05:01:34 GMT

If your energy bills spike every winter and certain rooms in your home still feel cold, your heating system may be working against you rather than for you. Across Melbourne’s eastern suburbs, Yarra Valley and Dandenong Ranges, thousands of homeowners rely on outdated or poorly sized gas heaters that waste energy and deliver inconsistent comfort.

A professional ducted gas heating installation in Melbourne can change that. When the right system is properly sized and installed by qualified technicians, every room reaches a comfortable temperature without the bill shock.

This guide covers what you need to know before upgrading your ducted gas heating.

From understanding how these systems work and choosing the correct size, through to installation timelines, VEU rebate savings and long-term maintenance. TruEast ’s team brings over 50 years of combined experience and fully licensed techn

Why Melbourne Homes Struggle with Heating Efficiency

Melbourne’s climate is demanding. Winter mornings regularly dip below 5°C in the outer eastern suburbs and ranges, while summer afternoons can climb past 40°C. Your heating system needs to handle cold snaps reliably without blowing out your gas bill.

The problem is that many homes across Croydon, Ringwood, Lilydale and the surrounding areas still run gas ducted heating units installed 15 to 20 years ago. These older systems often have star ratings of just 2 or 3 stars, meaning they convert only 60 to 70% of the gas they consume into actual heat. The rest is wasted energy that you pay for but never feel.

The Hidden Costs of an Ageing Gas Heater

An inefficient gas heater does more than increase your quarterly bill. It runs longer cycles to reach the set temperature, which accelerates wear on the fan motor, heat exchanger and thermostat. This leads to more frequent breakdowns and costly repair call-outs, often during the coldest weeks of the year when technicians are busiest.

There are also safety considerations. Older gas ducted heating units with cracked heat exchangers can leak carbon monoxide into your home’s air supply. Annual servicing helps detect this, but replacement becomes the only safe option once the exchanger deteriorates beyond repair.

Beyond the financial and safety costs, there is a missed opportunity. The Victorian Government’s Victorian Energy Upgrades (VEU) program offers significant rebates when you upgrade to a higher-efficiency system. Delaying your upgrade means leaving real savings on the table.

What Modern Melbourne Properties Actually Need

Today’s ducted gas heating systems operate at 5 to 6-star efficiency ratings, converting over 90% of consumed gas into warmth. Combined with electronic ignition (no constantly burning pilot light), variable-speed fans and programmable zoning, a modern system delivers consistent room-by-room comfort at a fraction of the running cost.

The key is proper sizing and professional installation. Even the best unit will underperform if it is too large or too small for your home, or if the ductwork is leaking conditioned air into the roof cavity.

How Ducted Gas Heating Works in Your Home

Understanding the basics helps you make an informed decision. A ducted gas heating system has three main components: the gas heater unit (usually installed in the roof space or under the floor) and a network of insulated ducts that carry warm air to each room and a return air grille that draws cooled air back to the unit for reheating.

When you set your thermostat, the unit ignites its gas burner and heats a metal heat exchanger. A fan blows air across this exchanger and pushes the warmed air through the duct network into your rooms. The system cycles on and off to maintain your chosen temperature.

Zoning: Heating Only the Rooms You Use

Modern ducted gas heating installations include zoning controls. Motorised dampers inside the ductwork open or close to direct warm air only to the rooms you select. This means you are not paying to heat empty bedrooms during the day or unused living areas at night.

A well-designed zoning setup can reduce your gas consumption by 20 to 30 % compared to running every outlet at once. Your installer should discuss which zones make sense for how your household actually uses different rooms throughout the day.

Choosing the Right Gas Ducted Heating System for Your Melbourne Home

Selecting the right system involves more than picking a brand. The following factors determine whether your new ducted gas heating delivers comfort and efficiency or just replaces one set of problems with another.

Heating Load Calculation

A professional heating load calculation accounts for your home’s floor area, ceiling height, insulation levels, window size and orientation, number of external walls and your local climate zone. Melbourne’s Eastern suburbs and Dandenong Ranges fall into climate zones that experience colder winters than inner-city areas, so the calculation must reflect this.

An undersized unit will run constantly, struggle to reach the set temperature and wear out faster. An oversized unit will short-cycle, switching on and off rapidly, which wastes gas and creates uneven temperatures. Proper sizing is the single most important factor in a successful gas ducted heating installation.

Star Ratings and What They Mean for Your Bills

In Australia, gas heaters are rated on a star system managed by the Energy Rating program . Each additional star represents roughly 10% better energy efficiency. Upgrading from a 2-star unit to a 5-star unit could reduce your gas heating costs by approximately 30%.

Look for units with a minimum 5-star rating. While 6-star models cost more upfront, the gas savings over the system’s 15 to 20-year lifespan typically outweigh the additional purchase price, especially if you heat your home frequently through Melbourne’s long winters.

Ductwork Condition and Design

Your existing ductwork may be reusable, but it needs inspection. Flexible ducts deteriorate over time, developing tears, sagging sections and failed insulation. Leaky ducts can waste 20 to 40% of the heated air before it reaches your rooms.

A qualified technician will assess whether your current ducts can be retained, repaired or need replacement. If you are renovating or extending your home, new ductwork should be designed alongside the heating upgrade to ensure balanced airflow to every room.

The Professional Installation Process

Make Your Melbourne Home Comfortable All Year Round

Upgrading to an energy-efficient split system is one of the smartest investments a Melbourne homeowner can make. With the Victorian Energy Upgrades program making it more affordable than ever, there's no reason to keep paying inflated energy bills for a system that doesn't deliver proper comfort.

The key is getting it right from the start: the right system, properly sized, professionally installed by qualified technicians and supported with ongoing maintenance.

A quality ducted gas heating installation follows a structured process from initial assessment through to commissioning and aftercare. The diagram below outlines what to expect at each stage.

Gas Ducted Heating vs Other Heating Options

Ducted gas heating is one of several options available to Melbourne homeowners. Understanding how it compares helps you decide which approach suits your property and budget.

Gas Ducted Heating

Fast, powerful heating ideal for Melbourne’s cold winters and larger homes
Lower running costs than electric resistance heating in most Victorian gas tariff areas
Zoning capability allows room-by-room control
Heating only (does not provide cooling)
Requires gas connection and suitable duct routes

Reverse Cycle Ducted (Heat Pump)

Provides both heating and cooling from one system
Highly energy-efficient, especially in moderate climates
Higher upfront cost but potentially lower combined running costs
Performance can drop in very cold conditions (below 2°C) without a cold-climate rated unit
Eligible for VEU rebates when replacing less efficient systems

Split System Air Conditioning

Affordable single-room heating and cooling solution
Easy to install without ductwork
Best for smaller homes, apartments or supplementing a ducted system
Multiple units needed for whole-home comfort, which adds cost

Which Option Suits Your Property?

For larger homes in Melbourne’s eastern suburbs and Yarra Valley that primarily need powerful winter heating, ducted gas heating remains a strong choice. If you also need cooling, a reverse-cycle ducted system or a combination of gas heating with a split-system cooling may be more practical.

TruEast assesses each property individually. The honest recommendation might be that your existing system only needs a repair, not a full replacement. That approach to diagnosis first is part of what sets qualified technicians apart.

The Real Cost of the Wrong System or Delayed Action

Choosing the wrong heating system or putting off a necessary upgrade has tangible financial consequences beyond a higher gas bill.

Undersized or Oversized Systems

An undersized gas heater in a Dandenong Ranges home, where winter temperatures drop lower than inner Melbourne, will never reach the set temperature on the coldest days. It runs non-stop, consuming maximum gas while delivering inadequate warmth.

An oversized system costs more to purchase and cycles on and off excessively. This rapid cycling prevents the system from running long enough to distribute heat evenly through the ductwork, leaving far rooms cooler than those near the unit.

Poorly Installed Systems

Missed VEU Rebate Opportunities

Installation quality matters as much as the unit itself. Common shortcuts include using undersized or poorly sealed ducts, failing to insulate ductwork in the roof cavity, incorrect gas pressure settings and skipping the commissioning process where airflow is balanced across all outlets.

These shortcuts might save time on installation day but create years of inefficiency, discomfort and premature component failure. Always confirm that your installer holds a full refrigeration and air conditioning licence, not a restricted licence that limits the scope of work they can legally perform.

Best Practices for Melbourne Homeowners Considering Ducted Gas Heating

The Victorian Energy Upgrades program provides rebates that can reduce your upfront costs by hundreds of dollars.

However, the rebate amount and eligibility criteria can change. Delaying a decision today may mean receiving a smaller rebate or missing out entirely if the program adjusts its incentives.

Knowing what to look for and what questions to ask puts you in a stronger position before committing to any heating upgrade.

Warning Signs Your System Needs Replacing

Questions to Ask Your HVAC Contractor

Your gas heater is 15 years or older
Energy bills have been increasing despite similar usage patterns
Some rooms take much longer to warm up than others
You hear banging, rattling or unusual noises during operation
The unit requires increasingly frequent repairs
You notice a yellow or flickering pilot flame (possible combustion issue)

When evaluating contractors for a gas ducted heating installation, these questions help you distinguish qualified professionals from those cutting corners. 

Do your technicians hold full air conditioning and refrigeration trade licences (not restricted licences)?
Will you perform a heating load calculation specific to my home?
Can you explain the star rating and expected running costs of the recommended unit?
Do you handle VEU rebate applications and paperwork?
What warranty and aftercare support do you provide?

Maintaining Your Gas Ducted Heating Between Services

Between professional services, a few simple steps keep your system performing well.

Clean or replace the return air filter every three to six months
Keep outlet grilles clear of furniture, curtains and other obstructions
Check that external flues and vents are not blocked by debris or vegetation
Listen for changes in operating sounds that may indicate developing issues

Professional servicing by a licensed gas fitter should be carried out annually. This includes checking the heat exchanger, gas pressure, burner operation and safety controls. Regular servicing extends the life of your system and maintains its efficiency.

Understanding and Claiming VEU Rebates

The Victorian Energy Upgrades program is administered by the Essential Services Commission and provides financial incentives for energy-efficient upgrades. When you install an eligible high-efficiency gas heater, a portion of the cost is covered through the rebate.

TruEast handles the entire VEU rebate process. The team manages the paperwork, eligibility checks and submissions so the rebate is applied directly to your installation cost. There is no separate claim for you to lodge.

How TruEast Approaches Ducted Gas Heating Installation in Melbourne

TruEast ’s process starts with listening. Before recommending any system, a qualified technician visits your property to understand what is and is not working with your current setup.

Assessment and Honest Recommendations

The technician inspects your existing heater, ductwork condition, insulation and home layout. If a repair is all that is needed, that is what TruEast recommends. There is no incentive to push a full replacement when a targeted fix restores performance.

When replacement is the right path, TruEast provides a clear recommendation with a specific unit model, star rating, expected running costs and the applicable VEU rebate amount. You receive all the information to make a confident decision.

Qualified Technicians, Not Restricted Licences

Every TruEast technician completes a full four-year apprenticeship in air conditioning and refrigeration. This is an important distinction. A restricted licence limits the type and size of systems a technician can legally work on.

 TruEast’s fully qualified team can install, service and repair any residential or commercial gas ducted heating system.

In-house training ensures that every team member meets TruEast’s standards for installation quality, customer communication and safety compliance.

Responsive Service and Long-Term Support

One of the most common frustrations homeowners share is contractors who are difficult to reach. TruEast’s commitment is responsive communication. Calls and messages are returned promptly, even if the initial response is simply to confirm when a detailed answer or visit will follow.

Based in Croydon, TruEast serves Melbourne’s eastern suburbs, the Yarra Valley and the Dandenong Ranges. The team provides installation, repair and ongoing maintenance, building long-term relationships rather than completing a job and disappearing.

Split System Rebate Victoria (VEU): How It Works

Thu, 23 Apr 2026 06:43:10 GMT

If your energy bills keep climbing and your old heater or air conditioner struggles to keep up, you're not alone. Thousands of Melbourne homeowners face the same frustration every summer and winter. The good news is that the split system rebate Victoria offers through the Victorian Energy Upgrades (VEU) program can significantly reduce the cost of upgrading to a modern, energy-efficient system.

But navigating eligibility requirements, understanding what's covered and finding the right installer can feel overwhelming. This guide breaks down everything you need to know about claiming a Victorian government split system rebate, from who qualifies to how the installation process works.

Whether you own a home in the eastern suburbs, Yarra Valley or Dandenong Ranges, understanding your options could save you thousands on a new system and hundreds each year on energy bills. TruEast are VEU rebate specialists who handle the entire process, so you can focus on enjoying year-round comfort.

Why Melbourne Homeowners Are Paying Too Much for Comfort

Melbourne's climate is unpredictable. Scorching summers in the high 30s can give way to single-digit winter mornings within months. That range puts enormous pressure on heating and cooling systems, especially older ones that were never designed to handle today's energy costs.

If your system is more than 10 years old, it's likely running well below the efficiency standards of modern units. Older ducted heaters, wall furnaces and single-function air conditioners often consume two to three times the energy of a current reverse-cycle split system. That translates directly into higher bills without delivering better comfort.

The hidden cost goes beyond electricity. An inefficient system works harder to maintain temperature, which accelerates wear on components. That means more frequent breakdowns, expensive repair callouts and the stress of a system failing on the hottest or coldest day of the year.

Many homeowners also don't realise they're missing out on government incentives. The Victorian Energy Upgrades program has been running for years, yet a significant number of eligible households haven't claimed their rebate. In some cases, that means paying full price for a system upgrade when a substantial discount was available.

Delaying an upgrade also means delaying savings. Every season you run an inefficient system is another quarter of inflated energy bills. For a typical three-bedroom home in suburbs like Croydon, Ringwood or Lilydale, upgrading from an old gas heater to a modern reverse cycle split system can reduce heating costs by up to 60 to 70 per cent, according to Sustainability Victoria .

What Is the Victorian Energy Upgrades Program?

The Victorian Energy Upgrades program (formerly known as the Victorian Energy Efficiency Target or VEET) is a state government initiative designed to help households and businesses reduce energy consumption. It does this by offering rebates and incentives on approved energy-efficient products, including split-system air conditioners and heat pumps.

Under the VEU program, accredited providers like TruEast can offer discounted installations because the government provides certificates for each eligible upgrade. These certificates have a tradeable value, which is passed on to you as a point of sale discount. You don't need to apply for a rebate after the fact or wait for reimbursement. The savings are applied upfront.

Who Is Eligible?

Eligibility for a split system rebate Victoria residents can access is straightforward. Your property needs to be located in Victoria and connected to the electricity grid. Both homeowners and renters (with landlord permission) can participate. The program covers residential and commercial properties.

The system being replaced generally needs to be an existing, operational heating or cooling unit. New builds may have different requirements. Your accredited provider will confirm eligibility during an initial assessment.

What Does the Rebate Cover?

The VEU program covers reverse-cycle split-system air conditioners that meet minimum energy efficiency requirements. The system must have a Zoned Energy Rating Label (ZERL) that meets the threshold set by the program.

Covered items typically include the supply and installation of the new split system, removal and disposal of the old unit, and all associated electrical and refrigeration work. The rebate amount varies depending on the system's capacity and efficiency rating. Higher efficiency units attract larger rebates.

Choosing the Right Split System for Your Home

Not every split system suits every property. Selecting the wrong size or type is one of the most common and costly mistakes Melbourne homeowners make.

Why Sizing Matters

An undersized system will run constantly, struggling to reach your desired temperature and driving up energy consumption. An oversized unit will cycle on and off too frequently, which wastes energy, increases wear and creates uncomfortable temperature swings. Proper sizing based on room dimensions, insulation, window orientation and local climate is essential.

A qualified technician should perform a heat load calculation before recommending a system. This accounts for factors specific to your property, not just the square metreage of a room. Homes in the Dandenong Ranges, for example, often need different specifications than those in lower-elevation suburbs due to cooler average temperatures.

Reverse Cycle Split Systems Explained

A reverse cycle split system is both a heater and an air conditioner in one unit. It works by transferring heat rather than generating it, which is why it uses significantly less energy than traditional gas heaters or electric bar heaters.

In cooling mode, it extracts heat from inside your home and releases it outside. In heating mode, it reverses the process, pulling warmth from the outdoor air (even in cold conditions) and pumping it inside. This heat pump technology is the reason reverse cycle systems are considered one of the most efficient forms of heating available in Australia.

For most Melbourne homes, a reverse cycle split system provides the best balance of upfront cost, running efficiency and year-round versatility.

System Options: Split Systems, Ducted and Multi-Split

When upgrading with a Victorian government split-system rebate, it helps to understand the main options available.

Single split systems are ideal for heating and cooling individual rooms or open-plan living areas. They're the most affordable option and simplest to install, making them popular for targeted comfort in bedrooms, living rooms or home offices.
Multi split systems connect multiple indoor units to a single outdoor compressor. This suits homes where you want climate control in several rooms without the complexity of full ducted systems. Each room can be set to a different temperature.
Ducted reverse cycle systems provide whole home comfort through ceiling or underfloor ducts. They're best suited to larger homes or new builds where ductwork can be integrated. The upfront investment is higher, but ducted systems offer discreet, even temperature distribution throughout the entire home.

For homes in suburbs like Mooroolbark, Montrose and Belgrave, where properties vary widely in size and layout, TruEast can assess which option delivers the best comfort and value for your specific situation.

The Cost of Getting It Wrong

Choosing the wrong system or installer doesn't just affect comfort. It affects your wallet for years to come.

An incorrectly sized system can add 30 to 40 per cent to your annual energy costs compared to a properly matched unit. Poor installation, including incorrect refrigerant charging, badly positioned outdoor units or inadequate drainage, will reduce system lifespan and efficiency from day one.

Using an installer who holds a restricted licence rather than a full trade qualification is another risk. Restricted licences allow basic installation work but not the diagnostic and repair expertise needed for long-term system performance. If something goes wrong, you may need to pay a fully qualified technician to fix the original work.

Then there's the rebate itself. If your installer isn't an accredited VEU provider, you miss the rebate entirely. Some homeowners only discover this after they've already paid full price for installation.

The bottom line is that a proper assessment, correct sizing, and qualified installation will protect your investment and maximise the value of your Victorian Energy Upgrades rebate

Best Practices for Melbourne Property Owners

A few practical steps can help you get more value from your heating and cooling system and avoid common pitfalls when upgrading.

Replace systems older than 10 to 12 years: Older units consume significantly more energy than modern alternatives and are more prone to breakdowns. If your energy bills have been climbing or your system struggles to maintain a comfortable temperature, an upgrade will likely pay for itself through lower running costs.
Always request a heat load calculation before installation : A properly sized system depends on your room dimensions, insulation, window orientation and local climate. Rough estimates lead to oversized or undersized units, both of which waste energy and reduce comfort.
Choose an installer with a full trade qualification : Look for technicians who have completed a four year apprenticeship in air conditioning and refrigeration, not a restricted licence. Full qualifications cover installation, diagnostics, repairs and ongoing servicing.
Check energy ratings for your specific climate zone: The Zoned Energy Rating Label (ZERL) shows how a system performs in different Australian regions. Make sure the rating you're comparing reflects Melbourne conditions, not a national average. Higher rated systems cost more upfront but deliver greater savings over their lifespan.
Claim your VEU rebate before your current system fails : Planning an upgrade while your old system is still running gives you time to compare options, book a proper assessment and avoid emergency pricing. TruEast handles all VEU administration, so you can focus on choosing the right system rather than navigating paperwork.

If you're unsure where to start, a professional assessment is the best first step.

How the VEU Rebate Process Works with TruEast

One of the biggest barriers to claiming a split-system rebate Victoria homeowners face is the paperwork. The VEU program involves specific documentation, compliance requirements and accreditation standards. TruEast handles all of this for you.

Here's how the process works:

Book a free assessment. A TruEast technician visits your property to assess your current system, perform a heat load calculation and discuss your comfort priorities.
Receive honest recommendations. Based on the assessment, you'll receive a clear recommendation for the right system, including the VEU rebate amount applied upfront. No pressure, no upselling.

Split System Air Conditioning Installation Melbourne

Tue, 07 Apr 2026 05:33:36 GMT

If your energy bills have been climbing and some rooms still feel too hot in summer or too cold in winter, your air conditioning setup is likely part of the problem. Whether you are dealing with an ageing unit that struggles through Melbourne's temperature swings or a home that has never had proper climate control, a well-planned split system air conditioning installation can transform your daily comfort and cut your running costs at the same time.

With over 50 years of combined experience, TruEast's fully licensed technicians specialise in helping property owners across Melbourne's eastern suburbs, Yarra Valley and Dandenong Ranges find the heating and cooling solution that genuinely fits their home. As accredited VEU rebate specialists, the team handles all the paperwork so you can access Victorian Energy Upgrades discounts without the hassle.

In this guide, you will learn what split system installation really costs, how to size a unit correctly, what the installation timeline looks like and what separates a quality aircon installation from a quick job that causes headaches down the track.

Why So Many Melbourne Homes End Up With the Wrong System

Heating and cooling account for roughly 40% of household energy use in Australia, according to the Australian government's Energy Rating program. The system you choose, and how well it is installed, directly impacts your comfort and your power bill.

Yet many homeowners across Melbourne's east end up with systems that are the wrong size, poorly positioned or installed by someone without the right qualifications. The result is a unit that cycles on and off too frequently, fails to heat or cool evenly and wears out years before its time.

An oversized split system blasts cold air, switches off, then restarts constantly. This wastes energy and creates uncomfortable temperature swings. An undersized unit runs flat out trying to reach a temperature it can never maintain, driving up electricity costs while leaving you uncomfortable.

Older units without inverter technology can use 30 to 40% more electricity than a modern reverse cycle split system. And if you are still running a gas heater, the Victorian Energy Upgrades (VEU) program offers significant discounts when you switch to an efficient reverse cycle air conditioner, with potential savings of up to $370 per year on operating costs for space heating alone.

What Does Split System Air Conditioner Installation Cost?

For a standard single split system (supply and installation) in Melbourne, most homeowners pay between $1,800 and $4,800. A straightforward back-to-back installation sits at the lower end. More complex jobs with longer pipe runs, difficult access or electrical upgrades push the price higher.

Multi-head split systems typically range from $4,200 to $8,000 depending on the number of indoor units and installation complexity.

Key factors that affect your final price include:

Unit capacity (kW size): A 2.5 kW bedroom unit costs significantly less than a 7 kW living area unit.
Brand and energy efficiency rating : Higher star-rated models cost more upfront but deliver lower running costs over their 10 to 15-year lifespan.
Installation complexity: Pipe run length, wall material, roof access and additional electrical circuits all influence labour costs.
VEU rebate eligibility: Replacing an old gas heater or upgrading from an inefficient system may qualify you for discounts that reduce your out-of-pocket cost.

Always get a fixed quote after a proper site assessment. A qualified technician needs to see your home to account for pipe runs, electrical requirements and unit placement before giving you an accurate price.

How to Size a Split System for Your Home

Getting the right kW capacity is the single most important decision in the entire air conditioning installation process.

As a starting point, allow roughly 120 to 150 watts of cooling capacity per square metre. A 20 square metre bedroom typically needs a 2.5kW unit, while a 40 square metre open-plan living area might require 5kW to 7kW. But square metres alone do not tell the full story.

A qualified technician will also consider ceiling height, insulation quality, window size and orientation, sun exposure and the number of heat-generating appliances. Homes in suburbs like Croydon, Ringwood or Montrose often have minimal insulation, which means extra capacity is needed. Properties in the Yarra Valley may benefit from natural shade, while those on the Dandenong Ranges with full sun exposure need more again.

Online sizing calculators give a ballpark figure but cannot assess insulation, air leakage or the specific microclimate of your property. TruEast's technicians carry out a proper heat load assessment before recommending a system, ensuring you get consistent comfort without wasting energy.

What Is Included in a Quality Installation?

A standard split system installation Melbourne homeowners should expect includes supply and mounting of the indoor unit, installation of the outdoor unit on a ground or wall bracket, refrigerant piping (usually up to 3 metres for back to back), electrical connection with a dedicated circuit, an isolating switch, condensate drainage, testing, commissioning and a walkthrough of your new system.

Longer pipe runs, switchboard upgrades, difficult access and structural modifications will add to the cost. A reputable installer identifies these extras during the site assessment and includes them in your fixed quote.

Timeline: A single split system typically takes three to four hours for a back-to-back setup. Complex installations or multi-head systems may take a full day. Book during autumn or winter for shorter wait times and you can take advantage of the heating mode through the cooler months.

Choosing the Right System Type

Single split system s are best for individual rooms or open-plan areas. They are the most affordable to install and energy-efficient for single-zone use.
Multi head split systems connect several indoor units to one outdoor compressor, suiting homes that need climate control in three or four rooms without multiple outdoor units.
Ducted reverse cycle systems distribute heating and cooling through ceiling ducts to every room. They cost significantly more ($10,000 to $20,000 or above) and work best in homes with suitable roof space.

For most homes in Melbourne's eastern suburbs, a combination of split systems in key living areas and bedrooms offers the best balance of comfort, efficiency and value. TruEast's approach is to assess your home honestly and recommend what genuinely suits your situation.

VEU Rebates: Reducing Your Installation Cost

The Victorian Energy Upgrades (VEU) program provides discounts on energy-efficient products, including reverse-cycle air conditioners. If you are replacing a gas heater or upgrading to a more efficient system, you may be eligible for a significant upfront discount.

The program has been extended through to 2045 and is open to all Victorian households with no income limits. The discount is applied at the point of sale, so you pay less on the day rather than claiming money back later.

As VEU accredited specialists, TruEast handles all the administration: confirming eligibility, completing paperwork and applying the maximum available discount to your quote. Combined with finance options like ZipPay and AfterPay, upgrading to an efficient system is more accessible than many homeowners expect.

Why Your Installer's Qualifications Matter

Split system installation must be carried out by a licensed refrigeration and air conditioning technician. Installers holding only a restricted electrical licence are not qualified to handle refrigerant or commission a system to manufacturer specifications.

A poorly installed system can void your warranty, leak refrigerant, operate inefficiently and pose safety risks. TruEast's technicians have completed full four-year apprenticeships in air conditioning and refrigeration, not short courses or restricted licences. Every installation meets manufacturer requirements, Australian standards and the quality level that protects your investment.

An older or incorrectly sized system can easily cost $200 to $400 more per year to run than a properly sized modern unit. Over 10 years, that adds up to $2,000 to $4,000 in wasted electricity, not including more frequent repair costs.

Best Practices for Melbourne Property Owners

Signs you need a replacement : your unit is over 10 to 12 years old and repair costs are increasing; rooms never reach a comfortable temperature; energy bills keep rising despite no change in usage; or you are still running a gas heater and want to switch to electric.
Understanding energy ratings: Since April 2020, all non-ducted split systems carry a Zoned Energy Rating Label showing star ratings for three climate zones. Melbourne sits in the cold zone. Each additional star typically represents a 15 to 25% reduction in energy consumption for units of the same capacity. Pay attention to heating efficiency as well as cooling, since your system works harder during Melbourne's longer winter months.
Maintenance between services : Clean indoor filters every four to six weeks during heavy use, keep the outdoor unit clear of debris, check the condensate drain is not blocked and schedule a professional service at least once a year.

How TruEast Works

TruEast 's process starts with an honest assessment, not a sales pitch. A qualified technician visits your property to assess room sizes, insulation, window orientation and your comfort priorities. Based on this, the team recommends the right system. If a repair makes more sense than a replacement, that is what they will recommend.

You receive a clear, fixed price quote covering everything: unit supply, installation, electrical work and VEU rebate deductions. Fully qualified technicians then carry out the work to manufacturer specifications, including proper commissioning and a system walkthrough.

Based in Croydon, TruEast serves homeowners and businesses across Melbourne's eastern suburbs, Yarra Valley and Dandenong Ranges. The team does not install and disappear. Ongoing maintenance, repairs and responsive communication are central to how the business operates.
