Ducted Gas and Reverse Cycle: Melbourne Homeowner Preferences 2026

If your gas ducted heating system is operational yet emitting unusual sounds, or if you've noticed an increase in your energy bills, a change may be on your mind. Are you contemplating whether to choose gas or reverse cycle heating for your Melbourne home in 2026? Let’s delve into these options comprehensively, without any sales language, so you can make an informed decision.

Explore Melbourne's Heating Regulations and Upcoming Changes for 2026

Starting January 1, 2024, the Victorian Government has introduced a gas ban for new residential developments. This regulation stipulates that any new homes requiring planning permits cannot connect to mains gas and must instead adopt all-electric systems. Enforced by the Victorian Department of Energy, Environment and Climate Action, this initiative applies statewide. For comprehensive information on this policy, visit the Energy Victoria website.

Here’s what homeowners need to understand about this policy:

• If your home currently uses gas: You do not need to make any immediate adjustments. You can continue using your existing ducted gas system, replace it with another gas unit when it eventually fails, or opt to transition to reverse cycle heating at your own pace.
• If you are building a new home: You must implement an all-electric system. Reverse cycle heating and cooling has become the standard for all new constructions.
• If you are undertaking significant renovations that require new gas lines: Consulting with your builder is essential, as some councils are beginning to enforce restrictions on new gas installations, even in existing properties.

Evaluate the Benefits of Ducted Gas Heating in Melbourne Homes

Ducted gas heating continues to be a practical choice for many households in Melbourne. The benefits are significant:

• Rapid heating: Gas burners reach their operational temperature swiftly. In contrast, reverse cycle systems may take longer to warm up, especially during chilly mornings when your home has cooled overnight.
• Reliable heat distribution: Well-designed ductwork ensures that heat is evenly distributed throughout your home, providing comfort in every room.
• Effective in extreme cold: Gas systems maintain their efficiency even when outside temperatures drop significantly. Although modern reverse cycle units perform adequately in Melbourne’s coldest conditions, gas systems hold a distinct advantage.
• Utilisation of existing infrastructure: If your ductwork, controls, and gas lines are in good condition, replacing your gas unit with another ducted gas heater is generally a cost-effective solution, often completed within a day, unlike transitioning to a reverse cycle system.

Compare the Advantages of Reverse Cycle Systems Against Ducted Gas

• Integrated heating and cooling: A reverse cycle system provides warmth in winter and cooling in summer, removing the need for a separate cooling system that ducted gas does not offer.
• Lower operating costs: Modern reverse cycle systems are highly efficient, producing three to five units of heat for each unit of electricity consumed, a level of efficiency that gas systems struggle to match.
• No combustion emissions: Reverse cycle systems eliminate the risks associated with gas combustion, including the need for flues and concerns regarding carbon monoxide safety.
• Advanced zoning capabilities: Many new reverse cycle systems allow for the independent heating or cooling of specific rooms, avoiding unnecessary energy expenditure in unoccupied spaces.
• Future-proof investment: With gas prices in Victoria increasing over the past five years, reverse cycle systems offer a hedge against rising energy costs.

Annual Running Cost Comparison for a Typical Three-Bedroom Home in Melbourne

Below are realistic estimates of annual running costs for a standard three-bedroom home in Melbourne during 2026, assuming average occupancy:

• Annual running cost for ducted gas: Typically ranges from $1,200 to $2,000, depending on usage patterns, energy tariffs, and the efficiency of the unit.
• Annual running cost for ducted reverse cycle: Generally falls between $700 and $1,400 for units rated five stars or higher.
• Cost savings: Households can anticipate savings of between 0 and 0 annually by switching, not accounting for the additional summer cooling provided by a reverse cycle system.

It is important to recognise that homes with poor insulation, oversized rooms, or extensive glass features may incur higher costs within these ranges, regardless of the heating system chosen. Addressing draughts, insulating ceilings, and implementing effective zoning strategies can significantly impact your energy bills more than the choice of heating system.

Identify Scenarios Where Ducted Gas Heating Remains a Strong Option

• If your current gas system is less than 10 years old and in good working order: You can replace it with a similar unit when it eventually fails, preserving an efficient asset.
• If your home has limited electrical capacity: Older homes with low-amperage supplies may require a switchboard upgrade to support a ducted reverse cycle system, potentially increasing overall transition costs.
• If you reside in a particularly cold area of Melbourne or regional Victoria: In frost-prone microclimates, reverse cycle systems may face challenges. It’s wise to assess your specific home rather than rely solely on general information.
• If heating is your sole requirement without cooling: A new ducted gas unit typically incurs a lower initial cost compared to a ducted reverse cycle system. If cooling is unnecessary, gas may still be the more economical option.

Recognise When Reverse Cycle Systems Are the Optimal Choice

• If your existing ducted gas unit is over 12 years old: You are nearing the end of its lifespan, making it more economical to incorporate cooling capabilities now rather than retrofit later.
• If you're weary of separate summer cooling expenses: Transitioning from multiple systems like split units or evaporative cooling to a single ducted reverse cycle system simplifies your setup and reduces overall costs.
• If you’re renovating or expanding your home: Installing new ductwork at this stage allows for a well-designed system rather than a makeshift solution.
• If you seek to lower energy costs: Reverse cycle systems consistently outperform ducted gas in running costs in Melbourne, and the gap is widening.
• If future resale value is a consideration: Potential buyers increasingly prefer energy efficiency and cooling options, where reverse cycle systems excel.

Address Common Questions About Heating Solutions in Melbourne

Is Gas Heating Being Phased Out in Victoria?

Not for existing homes. As of January 1, 2024, new residential constructions requiring planning permits are prohibited from connecting to mains gas and must transition to all-electric systems. Homes already connected to gas can continue using their systems, replace them with new gas appliances, or voluntarily opt for electric systems. The ban specifically targets new builds, not renovations.

Can I Replace My Old Ducted Gas System with a New Gas Unit?

Yes — if you live in an existing home that is already connected to gas, you can replace a failing ducted gas unit with a new one. The installation must be carried out by a licensed gas fitter in accordance with AS/NZS 5601 gas installation standards, but it is not affected by the bans on new constructions.

What Are the Costs Involved in Switching from Ducted Gas to Reverse Cycle in Melbourne?

For a typical three-bedroom home in Melbourne with existing ductwork in satisfactory condition, the installation of a ducted reverse cycle system starts at approximately $5,500 and can exceed $10,000 for larger homes with multiple zones or premium units. If an upgrade to your switchboard is necessary to manage the load, expect an additional cost of $1,500 to $2,500. Beyond provides fixed-price quotes following a complimentary in-home assessment, ensuring no fluctuating estimates once the work begins.

Do Reverse Cycle Systems Perform Efficiently During Melbourne Winters?

Yes — modern reverse cycle units are engineered to operate efficiently at temperatures as low as minus five degrees Celsius, which suffices for Melbourne's coldest mornings. While efficiency may dip in extreme cold compared to gas, for most Melbourne homes, the difference is minimal. Proper sizing of the unit based on your home’s heating requirements is more critical than merely the choice of system.

Will Transitioning to Reverse Cycle Lead to Real Savings?

Most households in Melbourne can expect to save between $400 and $800 annually on running costs when switching from ducted gas to ducted reverse cycle, assuming similar usage patterns. The potential savings could be even greater if you're currently utilising separate heating and cooling systems, as one ducted reverse cycle unit can replace both, eliminating the expenses associated with maintaining a second system.

Do I Need to Hire Both an Electrician and a Gas Fitter for the Transition?

Yes — a licensed gas fitter is essential for disconnecting and safely capping the old gas line, while a licensed electrician will manage the electrical setup for the new reverse cycle unit and any necessary switchboard upgrades. Beyond coordinates both trades as part of a comprehensive installation, so you won’t have to manage multiple contractors. Gas disconnection must be performed by a Type A gas fitter in accordance with Energy Safe Victoria regulations.

What Is the Typical Installation Timeline for a Reverse Cycle Ducted System?

For a standard three-bedroom home in Melbourne with existing ductwork, the full installation usually takes one to two days. If the existing ductwork requires replacement or reconfiguration, or if the switchboard needs upgrading, anticipate a timeframe of two to three days. We provide a detailed timeline as part of the quote to assist in your planning.
