Preferences of Melbourne Homeowners: Ducted Gas vs Reverse Cycle 2026

If your gas ducted heating system is operational but emitting unusual sounds or if you have noticed a spike 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 us delve into these options in detail, free from any sales rhetoric, to help you make an informed decision.

Explore Melbourne's Heating Regulations and Changes for 2026

As of January 1, 2024, the Victorian Government has enforced a gas ban for new residential constructions. This regulation dictates that any new homes requiring planning permits cannot connect to mains gas and must instead implement all-electric systems. This initiative is overseen by the Victorian Department of Energy, Environment and Climate Action and applies statewide. For comprehensive information about this policy, please visit the Energy Victoria website.

Here’s what this policy entails for homeowners:

• If your home relies on gas: There is no immediate requirement for changes. You may continue utilising your existing ducted gas system, replace it with another gas unit when it reaches the end of its life, or opt for a transition to reverse cycle heating at your leisure.
• 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 builds.
• If you are undertaking major renovations requiring new gas lines: It is essential to consult with your builder, as some councils are beginning to implement restrictions on new gas installations, even in established 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 operating temperature quickly. In contrast, reverse cycle systems may require more time to warm up, especially on chilly mornings after a cool night.
• Reliable heat distribution: Well-structured ductwork guarantees that heat is evenly spread throughout your home, ensuring comfort in every area.
• Performance in extreme cold: Gas systems remain efficient even when outside temperatures drop significantly. While modern reverse cycle units can operate effectively in Melbourne’s coldest conditions, gas systems typically have a notable advantage.
• Utilisation of existing infrastructure: If your ductwork, controls, and gas lines are in good repair, replacing your gas unit with another ducted gas heater is often cost-effective and can usually be completed in a single day, unlike switching to a reverse cycle system.

Compare the Advantages of Reverse Cycle Systems to Ducted Gas

• Dual 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 accommodate.
• Reduced operational costs: Current 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 often cannot match.
• No combustion emissions: Reverse cycle systems eliminate the hazards associated with gas combustion, including the need for flues and concerns regarding carbon monoxide safety.
• Improved zoning capabilities: Many modern reverse cycle systems allow for the independent heating or cooling of specific rooms, preventing unnecessary energy use in unoccupied areas.
• Future-proof investment: With gas prices in Victoria having risen over the past five years, reverse cycle systems offer a hedge against rising energy costs.

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

Below are estimated annual running costs for a standard three-bedroom home in Melbourne during 2026, based on average occupancy:

• Annual running cost for ducted gas: This typically ranges from $1,200 to $2,000, depending on usage habits, 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 anticipate saving between $400 and $800 annually by making the switch, not including the added summer cooling provided by a reverse cycle system.

It is important to note that homes with inadequate insulation, oversized rooms, or extensive glass features may face higher costs within these ranges, regardless of the chosen heating system. Addressing draughts, insulating ceilings, and employing effective zoning strategies can significantly impact your energy expenses more than the selection of heating system itself.

Identify When Ducted Gas Heating Remains a Strong Choice

• If your current gas system is less than 10 years old and functioning effectively: You can replace it with a similar unit when it eventually fails, preserving an efficient asset.
• If your home has limited electrical capacity: Older properties with low-amperage supplies may require a switchboard upgrade to support a ducted reverse cycle system, potentially increasing 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 difficulties. It is wise to assess your specific home rather than depend solely on general assumptions.
• If heating is your only requirement without cooling: A new ducted gas unit typically incurs a lower initial cost compared to a ducted reverse cycle system. If cooling is not a necessity, gas might still be the more economical option.

Recognise Scenarios Where Reverse Cycle Systems Are the Better Choice

• If your existing ducted gas unit is over 12 years old: You are nearing the end of its operational life, making it more economical to incorporate cooling capabilities now rather than retrofitting at a later stage.
• 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 expenditures.
• If you’re renovating or expanding your home: Installing new ductwork at this stage allows for a well-planned system rather than a makeshift solution.
• If you aim for lower energy costs: Reverse cycle systems consistently outperform ducted gas concerning running costs in Melbourne, and the gap is widening.
• If future resale value is important to you: 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 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 choose electric systems voluntarily. 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 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 compliance with AS/NZS 5601 gas installation standards, but it remains unaffected by the bans on new constructions.

What Are the Costs of 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 additional costs 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, sufficient for Melbourne's coldest mornings. While efficiency might dip in extreme cold compared to gas, for most Melbourne homes, the difference is minimal. Properly sizing the unit according to 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 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, 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 complete installation generally 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 schedule as part of the quote to aid in your planning.
