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’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 abode in 2026? Let’s delve into these alternatives comprehensively and without any promotional language, allowing you to make a well-informed decision.

Navigate Melbourne's Heating Regulations and Changes for 2026

Effective from 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 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.

This policy has several implications for homeowners:

• If your home relies on gas: You do not need to make any immediate changes. You can continue using your existing ducted gas system, replace it with another gas unit at the end of its life, or opt to transition to reverse cycle heating when it suits you.
• If you are building a new home: You must adopt an all-electric approach. Reverse cycle heating and cooling is now the mandated standard for all new constructions.
• If you are undertaking significant renovations that require 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 properties.

Explore the Benefits of Ducted Gas Heating for Melbourne Homes

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

• Rapid heating: Gas burners reach their operational temperature quickly. In contrast, reverse cycle systems may take longer to warm up, particularly during chilly mornings when your home has been cool overnight.
• Reliable heat distribution: Well-structured ductwork ensures that warmth is evenly spread throughout your home, delivering comfort in every room.
• Efficiency in extreme cold: Gas systems retain their performance even when outside temperatures drop significantly. Although modern reverse cycle units operate 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 generally a cost-effective solution and can often be completed within a day, unlike transitioning to a reverse cycle system.

Compare the Advantages of Reverse Cycle Systems Against Ducted Gas

• Combined heating and cooling: A reverse cycle system offers warmth during winter and cooling in summer, eliminating the need for a separate cooling system that ducted gas lacks.
• 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 individual 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 for a Typical Three-Bedroom Home in Melbourne

Here are realistic estimates for 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, 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 above.
• Cost savings: Households can expect to save between $400 and $800 annually by switching, not including the additional summer cooling provided by a reverse cycle system.

It is essential to recognise that homes with inadequate insulation, oversized rooms, or extensive glass features may incur higher costs within these ranges, regardless of the heating system selected. Addressing draughts, insulating ceilings, and employing effective zoning strategies can significantly affect 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, 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 advisable 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 typically has a lower initial cost compared to a ducted reverse cycle system. If cooling is unnecessary, 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 add cooling capabilities now rather than retrofit later.
• If you're weary of managing 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 aim to reduce energy costs: Reverse cycle systems consistently outperform ducted gas in 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 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 prohibited 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 affects 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 that is already connected to gas, you can replace a failing ducted gas unit with a new one. The installation must be performed by a licensed gas fitter in accordance with AS/NZS 5601 gas installation standards, but it is unaffected 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, anticipate 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 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 diminish 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 Actual 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 are currently using separate heating and cooling systems, as one ducted reverse cycle unit can replace both, eliminating the expenses 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 handle 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 do not need to manage 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 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.
