Ducted Gas and Reverse Cycle: Melbourne Homeowner Preferences 2026

If your gas ducted heating system is operational but making unusual noises, or if you have noticed an increase in your energy bills, you might be considering a change. Are you weighing the decision between gas and reverse cycle heating for your Melbourne home in 2026? Let’s delve into these options thoroughly and without any sales pitch, enabling you to make an informed decision.

Explore Melbourne's Heating Regulations and Upcoming Changes for 2026

Starting from January 1, 2024, the Victorian Government has enacted a gas ban for newly constructed residential properties. This regulation stipulates that any new homes requiring planning permits cannot connect to mains gas and must instead adopt all-electric systems. This initiative is enforced by the Victorian Department of Energy, Environment and Climate Action and applies throughout the state. For comprehensive details about this policy, please refer to the Energy Victoria website.

Here’s how this policy impacts homeowners:

• If your home uses gas: There is no immediate requirement to make changes. You can continue using your existing ducted gas system, replace it with another gas unit when it reaches the end of its lifespan, or opt for reverse cycle heating at your convenience.
• If you are building a new home: An all-electric approach is mandatory. Reverse cycle heating and cooling is now the standard for all new constructions.
• If you are undertaking significant renovations that require new gas lines: Consult with your builder, as some councils are beginning to enforce restrictions on new gas installations, even in existing homes.

Evaluate the Benefits of Ducted Gas Heating for Melbourne Homes

Ducted gas heating continues to be a viable choice for many households in Melbourne. Its notable advantages include:

• Rapid heating: Gas burners reach their operational temperature quickly. In contrast, reverse cycle systems may take longer to warm up, especially during chilly mornings when your home has been cool overnight.
• Reliable heat distribution: Well-designed ductwork ensures that heat is evenly distributed throughout your home, providing comfort in every room.
• Efficiency in extreme cold: Gas systems maintain their performance even when external temperatures drop significantly. While modern reverse cycle units operate sufficiently in Melbourne’s coldest conditions, gas systems generally have a clear 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 often economical and can typically be completed in a single day, unlike the transition to a reverse cycle system.

Compare the Advantages of Reverse Cycle Systems to Ducted Gas

• Dual heating and cooling: A reverse cycle system provides heating in winter and cooling in summer, removing the need for a separate cooling system that ducted gas does not provide.
• Reduced operational costs: Modern reverse cycle systems are highly efficient, generating three to five units of heat for each unit of electricity consumed, a level of efficiency that gas systems find challenging to match.
• No combustion emissions: Reverse cycle systems eliminate the risks associated with gas combustion, including the need for flues and concerns about carbon monoxide safety.
• Improved zoning capabilities: Many contemporary reverse cycle systems allow for specific rooms to be heated or cooled independently, preventing unnecessary energy use in unoccupied spaces.
• Future-proof investment: With gas prices in Victoria rising over the last five years, reverse cycle systems offer a buffer against escalating energy costs.

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

Here are practical annual running cost estimates for a typical three-bedroom home in Melbourne for 2026, assuming average occupancy:

• Annual running cost for ducted gas: This typically ranges from $1,200 to $2,000, depending on usage patterns, energy tariffs, and unit efficiency.
• Annual running cost for ducted reverse cycle: This generally falls between $700 and $1,400 for units rated five stars or above.
• Cost savings: Households can expect to save between $400 and $800 annually by switching, not including the additional summer cooling provided by a reverse cycle system.

It’s important to recognise that homes with insufficient 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.

Recognise Circumstances 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, maintaining an efficient asset.
• If your home has limited electrical capacity: Older homes with low-amperage supplies may require a switchboard upgrade to accommodate a ducted reverse cycle system, which can increase the overall transition costs.
• If you live in a particularly cold area of Melbourne or regional Victoria: In frost-prone microclimates, reverse cycle systems may encounter challenges. It's wise to assess your specific home rather than relying solely on general information.
• If heating is your only need without cooling: A new ducted gas unit typically has a lower initial cost compared to a ducted reverse cycle system. If cooling isn't a requirement, gas might still be the more economical choice.

Identify When Reverse Cycle Systems Are the Preferred Option

• If your existing ducted gas unit is over 12 years old: You are nearing the end of its lifespan, making it more cost-effective to include cooling capabilities now rather than retrofitting 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 are renovating or expanding your home: Installing new ductwork at this stage allows for a well-designed system rather than a temporary solution.
• If you seek lower energy costs: Reverse cycle systems consistently outperform ducted gas regarding running costs in Melbourne, and the gap is widening.
• If future resale value is a consideration: Potential buyers increasingly favour energy efficiency and cooling options, where reverse cycle systems excel.

Address Frequently Asked 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 barred from connecting to mains gas and must transition to all-electric systems. Homes already connected to gas can continue to use 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 Associated with 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 Operate Efficiently During Melbourne Winters?

Yes — modern reverse cycle units are designed to function efficiently at temperatures as low as minus five degrees Celsius, which is suitable 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 needs is more crucial than merely the type of system.

Will Transitioning to Reverse Cycle Lead to Genuine 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 are currently using separate heating and cooling systems, as one ducted reverse cycle unit can replace both, eliminating the costs related to 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 compliance 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 typically takes one to two days. If the existing ductwork requires replacement or reconfiguration, or if the switchboard needs upgrading, expect a timeframe of two to three days. We provide a detailed schedule as part of the quote to assist in your planning.
