Preferences of Melbourne Homeowners for Ducted Gas and Reverse Cycle 2026

If your gas ducted heating system is operational yet emits unusual sounds or if you've noticed an increase in your energy bills, you might be considering a change. Are you weighing the benefits of gas versus reverse cycle heating for your Melbourne home in 2026? Let’s delve into these options in detail, without any sales jargon, so you can make an informed decision.

Explore Melbourne's Heating Regulations and Changes for 2026

Beginning 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 must not connect to mains gas and must instead implement all-electric systems. This initiative is enforced by the Victorian Department of Energy, Environment and Climate Action and applies statewide. For comprehensive details on this policy, visit the Energy Victoria website.

Here’s what this policy implies for homeowners:

• If your home is gas-powered: You are not required to make any immediate changes. You can continue using your existing ducted gas system, replace it with another gas unit when the time comes, or opt to switch to reverse cycle heating at your convenience.
• If you are building a new home: You must adopt an all-electric approach. Reverse cycle heating and cooling is now the standard for all new constructions.
• If you are planning substantial renovations that require new gas lines: It’s essential to consult your builder, as some councils are beginning to enforce restrictions on new gas installations, even within existing homes.

Evaluate the Benefits of Ducted Gas Heating for Melbourne Homes

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

• Rapid heating: Gas burners reach their operational temperature quickly. In contrast, reverse cycle systems may take longer to warm up, especially during cold mornings when your home has cooled overnight.
• Reliable heat distribution: Properly designed ductwork ensures that heat is evenly circulated throughout your home, providing comfort in every room.
• Efficiency in extreme cold: Gas systems maintain their effectiveness even when outside temperatures drop significantly. While modern reverse cycle units perform adequately in Melbourne’s coldest conditions, gas systems typically have a decisive advantage.
• Utilisation of existing infrastructure: If your ductwork, controls, and gas lines are in good condition, replacing your current gas unit with another ducted gas heater is generally a cost-effective option and can often be completed in just one day, unlike the transition to a reverse cycle system.

Compare the Benefits of Reverse Cycle Systems Against Ducted Gas

• Dual heating and cooling: A reverse cycle system provides both warmth in winter and cooling in summer, eliminating the need for an additional cooling system that ducted gas does not support.
• Reduced operational costs: Modern reverse cycle systems are highly efficient, producing three to five units of heat for every unit of electricity used, an efficiency that gas systems often cannot 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 individual room heating or cooling, preventing unnecessary energy use in unoccupied areas.
• Future-proof investment: With gas prices in Victoria increasing over the past five years, reverse cycle systems offer protection against rising energy costs.

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

Below are realistic estimates for the annual running costs of 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 unit efficiency.
• 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 $400 and $800 annually by switching, not factoring in the additional summer cooling provided by a reverse cycle system.

It is important to note that homes lacking adequate insulation, featuring oversized rooms, or extensive glass elements 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 Situations Where Ducted Gas Heating Remains a Strong Option

• If your current gas system is less than 10 years old and operating efficiently: You can replace it with a similar unit when it eventually fails, maintaining an efficient asset.
• If your home has limited electrical capacity: Older residences with low-amperage supplies may require a switchboard upgrade to accommodate a ducted reverse cycle system, potentially increasing the overall transition cost.
• If you live in an especially cold area of Melbourne or regional Victoria: In frost-prone microclimates, reverse cycle systems may encounter challenges. It is wise to assess your specific home rather than relying solely on generalised information.
• If heating is your only requirement without cooling: A new ducted gas unit typically has a lower initial cost compared to a ducted reverse cycle system. If cooling is not a priority, gas may still be the more economical choice.

Recognise 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 gain 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’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 terms of running costs in Melbourne, and the gap is widening.
• If potential resale value is important: Prospective buyers increasingly prefer energy-efficient homes with cooling options, where reverse cycle systems excel.

Answering 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 barred 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 switch to 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 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. Should an upgrade to your switchboard be 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 commences.

Do Reverse Cycle Systems Operate Efficiently During Melbourne Winters?

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

Will Transitioning to Reverse Cycle Yield Real Savings?

Most households in Melbourne can anticipate savings of 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 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 securely 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 juggle 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 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.
