Ducted Gas and Reverse Cycle: Melbourne Homeowners’ Choices 2026

If your gas ducted heating system is operational but making unusual sounds, or if you've noticed a spike in your energy bills, you might be considering a change. Are you evaluating whether to select gas heating or reverse cycle heating for your Melbourne home in 2026? Let’s thoroughly investigate these options without any sales jargon, allowing you to make an informed decision.

Understand the New Heating Regulations in Melbourne for 2026

As of 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 are prohibited from connecting to mains gas and must adopt all-electric systems. This initiative is enforced by the Victorian Department of Energy, Environment and Climate Action and applies statewide. For comprehensive details about this policy, please visit the Energy Victoria website.

Here’s what this policy entails for homeowners:

• If your home currently uses gas: You are not required to make any immediate changes. You may continue using your existing ducted gas system, replace it with another gas unit when it reaches the end of its service life, or choose to transition to reverse cycle heating at your leisure.
• If you are building a new home: You will need to adopt an all-electric approach. Reverse cycle heating and cooling is now the 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 starting to impose restrictions on new gas installations, even within existing homes.

Explore the Benefits of Ducted Gas Heating in Melbourne Homes

Ducted gas heating remains a popular option for many households in Melbourne. Its advantages include:

• Rapid heating: Gas burners reach their operational temperature quickly. In contrast, reverse cycle systems may take longer to heat a space, especially during cold mornings when your home has been cool overnight.
• Reliable heat distribution: Well-designed ductwork ensures an even spread of heat throughout your home, delivering comfort in every room.
• Effective performance in extreme cold: Gas systems maintain their efficiency even when outside temperatures drop significantly. While modern reverse cycle units perform adequately in Melbourne’s chilliest conditions, gas systems tend to have a clear 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 usually a cost-effective solution and can often be completed in a single day, unlike transitioning to a reverse cycle system.

Evaluate the Advantages of Reverse Cycle Systems Over Ducted Gas

• Combined heating and cooling: A reverse cycle system provides warmth in winter and cooling in summer, negating 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 every 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 about carbon monoxide safety.
• Improved zoning capabilities: Many new reverse cycle systems enable specific rooms to be heated or cooled independently, preventing unnecessary heating in unoccupied areas.
• Long-term investment: With gas prices in Victoria rising over the past five years, reverse cycle systems provide a safeguard against increasing energy costs.

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

Below are realistic estimates of annual running costs for a standard 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 higher.
• Cost savings: Households can expect to save between $400 and $800 annually by making the switch, excluding the additional summer cooling provided by a reverse cycle system.

It is important to note that homes with poor insulation, oversized rooms, or extensive glass features may incur higher costs within these ranges, regardless of the heating system chosen. Addressing draughts, insulating ceilings, and employing effective zoning strategies can have a more significant impact on your energy bills than the choice of heating system.

Discover Situations Where Ducted Gas Heating Remains a Solid Option

• If your current gas system is under 10 years old and in good condition: 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 overall transition costs.
• If you live in a particularly cold area of Melbourne or regional Victoria: In frost-prone microclimates, reverse cycle systems may face limitations. It is wise to evaluate your specific home instead of relying solely on general information.
• If heating is your only requirement without cooling: A new ducted gas unit typically costs less upfront compared to a ducted reverse cycle system. If cooling is not a necessity, gas might still be the more economical choice.

Recognise When Reverse Cycle Systems Are the Preferred Choice

• If your existing ducted gas unit is over 12 years old: You are nearing the end of its lifespan, making it more cost-effective to include cooling capabilities now rather than retrofitting later.
• If you wish to avoid 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 are renovating or expanding your home: Installing new ductwork at this stage allows for a well-designed system instead of a makeshift solution.
• If you aim 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-efficient homes with 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 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 voluntarily switch to 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 already uses 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 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 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 decline in extreme cold compared to gas, for most Melbourne homes, the difference is negligible. Proper sizing of the unit based on your home’s heating needs is more critical than simply the choice of system.

Will Transitioning to Reverse Cycle Result in 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. 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 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 need to deal with 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 typically 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.
