Ducted Gas and Reverse Cycle Preferences Among Melbourne Homeowners 2026

If your gas ducted heating system is operational but emitting unusual sounds or if you've noticed an increase in your energy bills, you might be considering a change. Are you deliberating whether to choose gas or reverse cycle heating for your Melbourne home in 2026? Let’s delve into these options comprehensively and without any sales jargon, empowering you to make an informed decision.

Comprehend Melbourne's Heating Regulations and Changes for 2026

Beginning January 1, 2024, the Victorian Government has enacted a gas ban for new 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 statewide. For detailed information regarding this policy, please visit the Energy Victoria website.

Here’s what this policy signifies for homeowners:

• If your home relies on gas: There is no requirement for immediate changes. You can continue to utilise your existing ducted gas system, replace it with another gas unit when it reaches the end of its life, or opt for reverse cycle heating at your leisure.
• If you are building a new home: You will need to implement an all-electric solution. Reverse cycle heating and cooling has now become the standard for all new constructions.
• If you are undertaking major renovations that require new gas lines: It is essential to consult with your builder, as certain councils are beginning to impose restrictions on new gas installations, even within existing homes.

Evaluate the Benefits of Ducted Gas Heating in Melbourne Homes

Ducted gas heating remains a practical choice for many households in Melbourne. Its benefits are considerable:

• Rapid heating: Gas burners reach their operating temperature quickly. In contrast, Reverse cycle systems may take longer to warm up, especially on cold mornings when your home has been chilly overnight.
• Reliable heat distribution: Efficiently designed ductwork guarantees that heat is evenly distributed throughout your home, ensuring comfort in every room.
• Performance in severe cold: Gas systems retain their efficiency even when outside temperatures drop significantly. Although 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 well-maintained, replacing your gas unit with another ducted gas heater is typically a cost-effective option and can often be completed in a single day, unlike the transition to a reverse cycle system.

Compare the Advantages of Reverse Cycle Systems Against Ducted Gas

• Dual heating and cooling: A reverse cycle system delivers warmth in winter and cooling in summer, removing the necessity for a separate cooling system that ducted gas does not provide.
• Reduced operational costs: Contemporary reverse cycle systems are highly efficient, producing three to five units of heat for every unit of electricity consumed, a level of efficiency that gas systems struggle to match.
• No combustion emissions: Reverse cycle systems eliminate risks associated with gas combustion, including the need for flues and concerns regarding carbon monoxide safety.
• Improved zoning capabilities: Many new reverse cycle systems enable independent heating or cooling of specific rooms, preventing unnecessary heating in unoccupied areas.
• Investment for the future: With gas prices in Victoria increasing over the past five years, reverse cycle systems shield you against rising energy expenses.

Annual Running Cost 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 for 2026, based on average occupancy:

• Annual running cost for ducted gas: This typically ranges from $1,200 to $2,000, influenced by usage habits, 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 above.
• Cost savings: Households can anticipate saving between $400 and $800 annually by making the switch, not taking into account the additional summer cooling provided by a reverse cycle system.

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

Situations Where Ducted Gas Heating Remains a Strong Option

• If your current gas system is less than 10 years old and operating efficiently: You may replace it with a similar unit upon its failure, 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 cost.
• If you live in a particularly 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 general information.
• If heating is your only 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 priority, gas might still be the more economical option.

Recognise Scenarios Where Reverse Cycle Systems Are the Superior 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 integrate 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 extending 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 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 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 reside 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 conducted 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 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 starts.

Do Reverse Cycle Systems Perform Efficiently During Melbourne Winters?

Yes — modern reverse cycle units are designed to operate efficiently at temperatures as low as minus five degrees Celsius, which is sufficient for Melbourne's coldest mornings. While efficiency may decline in extreme cold compared to gas, for the majority of 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 Result in 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 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 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, ensuring 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 complete installation usually takes one to two days. If the existing ductwork needs replacement or reconfiguration, or if the switchboard requires upgrading, expect a timeframe of two to three days. We provide a detailed schedule as part of the quote to assist in your planning.
