Ducted Gas and Reverse Cycle Preferences Among Melbourne Homeowners 2026

If your gas ducted heating system is operational but emits unusual sounds or if there has been a noticeable increase in your energy bills, you might be considering a change. Are you deliberating on whether to choose gas heating or reverse cycle heating for your Melbourne home in 2026? Let’s delve into these options in detail, providing you with the information needed to make an informed decision.

Explore Melbourne's Heating Regulations and Upcoming Changes for 2026

Starting January 1, 2024, the Victorian Government has introduced a gas ban for new residential properties. This regulation requires that any new homes seeking planning permits cannot connect to mains gas and must instead utilise all-electric systems. Enforced by the Victorian Department of Energy, Environment and Climate Action, this policy applies statewide. For comprehensive information about this initiative, please visit the Energy Victoria website.

Here’s what this regulation entails for homeowners:

• If your home is currently using gas: There is no immediate obligation to change. You can continue using your existing ducted gas system, replace it with another gas unit when it reaches the end of its life, or choose 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 industry standard for all new constructions.
• If you are making significant renovations that require new gas lines: It is essential to consult your builder, as some councils are beginning to impose restrictions on new gas installations, even in existing homes.

Evaluate the Benefits of Ducted Gas Heating for Melbourne Homes

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

• Rapid heating: Gas burners reach their operational temperature swiftly. In contrast, reverse cycle systems can take longer to heat up, especially on chilly mornings when your home has been cool overnight.
• Reliable heat distribution: Properly designed ductwork ensures that heat is evenly spread throughout your home, providing a comfortable atmosphere in every room.
• Performance in severe cold: Gas systems maintain their efficiency even when outside temperatures drop significantly. While modern reverse cycle units perform adequately in Melbourne's coldest conditions, gas systems tend to 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 often a cost-effective option, typically completed within a single day, unlike switching to a reverse cycle system.

Compare the Advantages of Reverse Cycle Systems Against Ducted Gas

• Integrated heating and cooling: A reverse cycle system provides warmth in winter and cooling in summer, eliminating the need for a separate cooling system that ducted gas does not provide.
• Reduced operational costs: Modern reverse cycle systems are highly efficient, producing three to five units of heat for each unit of electricity consumed, an efficiency level 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 contemporary reverse cycle systems allow for specific 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 offer protection against rising energy costs.

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

Here are realistic annual running cost estimates for a typical 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, 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 above.
• Cost savings: Households can anticipate savings of between $400 and $800 annually by switching, not considering the additional summer cooling provided by a reverse cycle system.

It is important to note that homes with insufficient insulation, oversized rooms, or extensive glass features may experience costs at the higher end of these ranges, regardless of the heating system chosen. Addressing draughts, insulating ceilings, and employing effective zoning strategies can significantly reduce your energy bills more than the type of heating system selected.

Identify Scenarios Where Ducted Gas Heating Remains a Strong Option

• If your current gas system is under 10 years old and operating 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 properties 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 sole 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 necessary, gas may still be the more economical option.

Recognise Scenarios Where Reverse Cycle Systems Are the Optimal 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, such as 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 an improvised solution.
• If you seek lower energy costs: Reverse cycle systems consistently outperform ducted gas in terms of operating costs in Melbourne, with the gap widening.
• If future resale value is a consideration: Potential buyers increasingly prioritise energy efficiency and cooling options, where reverse cycle systems excel.

Seek Professional Guidance to Determine Your Home’s Ideal Heating Solution

For the majority of Melbourne homes in 2026, reverse cycle ducted systems present a more advantageous long-term solution.

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 prohibited from connecting to mains gas and must shift to all-electric systems. Homes already connected to gas can continue operating 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 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 carried out 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 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 required to handle 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 unexpected estimates once the work commences.

Do Reverse Cycle Systems Function Effectively During Melbourne Winters?

Yes — modern reverse cycle units are engineered to operate 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 most Melbourne homes, the difference is minimal. Proper sizing of the unit based on your home’s heating needs is more crucial than merely the system type.

Will Transitioning to Reverse Cycle Lead to Genuine 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. 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 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 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 need to oversee 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 requires replacement or reconfiguration, or if the switchboard needs upgrading, expect a timeframe of two to three days. We provide a detailed schedule as part of the quote to assist in your planning.
