Ducted Gas and Reverse Cycle Preferences Among Melbourne Homeowners 2026

If your gas ducted heating system is operational yet emitting unusual noises, or if you've noticed an increase in your energy bills, you might be considering a change. Are you deliberating between gas heating and reverse cycle heating for your Melbourne home in 2026? Let's delve into these options comprehensively, devoid of any sales rhetoric, so you can make an informed decision.

Explore Melbourne's Heating Regulations and Changes for 2026

Effective from January 1, 2024, the Victorian Government has instituted a gas ban for new residential constructions. This regulation stipulates that any new homes requiring planning permits cannot connect to mains gas and must instead implement all-electric systems. The Victorian Department of Energy, Environment and Climate Action enforces this policy across the state. For comprehensive details regarding this initiative, please visit the Energy Victoria website.

Here’s what this policy entails for homeowners:

• If your home currently uses gas: You are not required to make any immediate changes. You may continue utilising your existing ducted gas system, replace it with another gas unit at the end of its lifespan, or opt to transition to reverse cycle heating at your convenience.
• If you are building a new home: You will need to adopt an all-electric approach. Reverse cycle heating and cooling is now the standard for all new constructions.
• If you are undertaking significant renovations requiring new gas lines: It is essential to consult with your builder, as some councils are beginning to impose restrictions on new gas installations, even in existing homes.

Weigh the Advantages of Ducted Gas Heating for Melbourne Homes

Ducted gas heating remains a practical choice for many households in Melbourne, offering several benefits:

• Rapid heating: Gas burners quickly reach their operational temperature. In contrast, reverse cycle systems may take longer to warm up, especially during cold mornings when your home has been chilly overnight.
• Reliable heat distribution: Effectively designed ductwork ensures that heat is evenly spread throughout your home, providing comfort in every room.
• Efficient in extreme cold: Gas systems maintain their performance even when external temperatures fall dramatically. While modern reverse cycle units perform adequately in Melbourne's coldest conditions, gas systems have 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 typically a cost-effective choice, often completed in a single day, unlike transitioning to a reverse cycle system.

Evaluate the Benefits of Reverse Cycle Systems Over Ducted Gas

• Integrated heating and cooling: A reverse cycle system offers warmth in winter and cooling in summer, eliminating the need for a separate cooling system that ducted gas does not provide.
• Reduced operational 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.
• Improved zoning capabilities: Many new reverse cycle systems allow for specific rooms to be heated or cooled independently, preventing unnecessary heating in unoccupied areas.
• Future-proof investment: With gas prices in Victoria increasing over the past five years, reverse cycle systems provide a safeguard against rising energy costs.

Annual Running Costs 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: This typically ranges from $1,200 to $2,000, influenced by usage patterns, energy tariffs, and the efficiency of the unit.
• Annual running cost for ducted reverse cycle: This generally falls between $700 and $1,400 for units rated five stars or higher.
• Cost savings: Households can expect to save between 0 and 0 annually by making the switch, not including the added cooling benefits provided by a reverse cycle system.

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

Recognise Scenarios Where Ducted Gas Heating Remains a Strong Option

• If your current gas system is less than 10 years old and operational: 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 elevate the overall transition cost.
• If you live in a particularly cold region 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 assessments.
• If heating is your sole requirement without cooling: A new ducted gas unit generally has a lower initial cost compared to a ducted reverse cycle system. If cooling is not a necessity, gas might still be the more economical choice.

Understand 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 operational life, making it more cost-effective to incorporate cooling capabilities now rather than retrofitting later.
• If you're weary of separate summer cooling costs: Transitioning from multiple systems like split units or evaporative cooling to a single ducted reverse cycle system simplifies your setup and reduces overall expenses.
• If you’re renovating or expanding your home: Installing new ductwork at this stage enables a well-designed system rather than a makeshift 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 are increasingly prioritising energy efficiency and cooling options, where reverse cycle systems excel.

Address Common Questions Regarding 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 banned 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 already connected to gas, you can replace a failing ducted gas unit with a new one. The installation must be completed by a licensed gas fitter in accordance with AS/NZS 5601 gas installation standards, but it is not affected by the ban 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 acceptable condition, the installation of a ducted reverse cycle system starts at approximately $5,500 and may exceed $10,000 for larger homes with multiple zones or high-end units. If an upgrade to your switchboard is necessary to handle the load, expect an additional expense 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 decline in extreme cold compared to gas, for most Melbourne homes, the difference is marginal. Properly sizing the unit based on your home’s heating requirements is more crucial than merely choosing the system.

Will Transitioning to Reverse Cycle Result in Tangible Savings?

Most households in Melbourne can anticipate saving between $400 and $800 annually on running costs when transitioning from ducted gas to ducted reverse cycle, assuming similar usage patterns. The potential savings could be even greater if you're currently using separate heating and cooling systems, as one ducted reverse cycle unit can replace both, eliminating the costs 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 necessary 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 required switchboard upgrades. Beyond coordinates both trades as part of a comprehensive installation, so you won’t need to liaise with multiple contractors. Gas disconnection must be carried out 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 entire installation usually takes one to two days. If the existing ductwork necessitates replacement or reconfiguration, or if the switchboard requires upgrading, anticipate a timeframe of two to three days. We provide a detailed schedule as part of the quote to assist in your planning.
