Preferences of Melbourne Homeowners: Ducted Gas vs Reverse Cycle 2026

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

Explore Melbourne's Heating Regulations and Changes for 2026

As of January 1, 2024, the Victorian Government has enacted a gas ban for new residential constructions. This regulation stipulates that any new homes requiring planning permits are prohibited from connecting 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 regarding this policy, please visit the Energy Victoria website.

Here’s what this regulation means for homeowners:

• If your home uses gas: You are not required to make immediate 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 to transition to reverse cycle heating at your convenience.
• If you are building a new home: An all-electric approach is mandatory. Reverse cycle heating and cooling has become the standard for all new constructions.
• If you are undergoing significant renovations requiring new gas lines: It is essential to consult with your builder, as some councils are beginning to enforce restrictions on new gas installations, even in existing properties.

Evaluate the Benefits of Ducted Gas Heating for Melbourne Homes

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

• Quick heating: Gas burners reach their operational temperature rapidly. 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 retain their effectiveness even when outside temperatures drop significantly. Although modern reverse cycle units perform adequately in Melbourne’s coldest weather, gas systems hold 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 option and can often be completed in a single day, unlike the transition to a reverse cycle system.

Investigate the Advantages of Reverse Cycle Systems Over Ducted Gas

• Combined heating and cooling: A reverse cycle system offers warmth in winter and cooling in summer, removing the need for a separate cooling system that ducted gas does not provide.
• Reduced operational costs: Contemporary reverse cycle systems are exceptionally efficient, generating three to five units of heat for each unit of electricity consumed, an 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 surrounding carbon monoxide safety.
• Improved zoning capabilities: Many new reverse cycle systems allow for independent heating or cooling of specific rooms, preventing unnecessary energy use in unoccupied spaces.
• Future-proof investment: With gas prices in Victoria rising over the past five years, reverse cycle systems provide a buffer against increasing energy costs.

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

Below are realistic annual running cost estimates for an average three-bedroom home in Melbourne during 2026, assuming standard occupancy:

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

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

Identify Scenarios Where Ducted Gas Heating Remains a Strong Option

• If your current gas system is under 10 years old and functioning well: You can replace it with a similar unit when it eventually fails, preserving 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, 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 challenges. It’s wise to evaluate your specific home rather than rely solely on general information.
• 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 necessary, gas might still be the more economical choice.

Recognise When Reverse Cycle Systems Are the Superior Option

• If your existing ducted gas unit is over 12 years old: You are nearing the end of its lifespan, making it more economical 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 allows for a well-designed system rather than a makeshift solution.
• If your goal is to lower energy costs: Reverse cycle systems consistently outperform ducted gas in terms of running costs in Melbourne, and the gap is widening.
• If future resale value is a consideration: Potential buyers increasingly prefer 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?

No, not for existing homes. As of January 1, 2024, new residential constructions requiring planning permits are prohibited 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 choose electric systems. The ban specifically applies to 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 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 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 accommodate the load, anticipate 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 commences.

Do Reverse Cycle Systems Function Effectively During Melbourne Winters?

Yes — modern reverse cycle units are designed to operate 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 relative 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 crucial than merely the choice of system.

Will Transitioning to Reverse Cycle Lead to Real Savings?

Most households in Melbourne can anticipate saving between $400 and $800 annually on running costs when switching from ducted gas to ducted reverse cycle, assuming similar usage patterns. 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 Engage 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 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 full 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.
