Ducted Gas and Reverse Cycle: Melbourne Homeowners’ 2026 Choices

If your gas ducted heating system operates but emits unusual sounds or if you’ve noticed an increase in your energy bills, you might be considering a change. Are you weighing the options between gas and reverse cycle heating for your Melbourne home in 2026? Let’s delve into these alternatives in detail, devoid of any sales rhetoric, so you can make an informed decision.

Explore Melbourne's Heating Regulations and Updates for 2026

Starting from January 1, 2024, the Victorian Government has instituted a gas ban for newly constructed residential properties. This legislation stipulates that any new homes requiring planning permits cannot connect to mains gas and must instead 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 relies on gas: You are not compelled to make immediate alterations. You may continue utilising your existing ducted gas system, replace it with another gas unit when it reaches the end of its lifespan, or opt for reverse cycle heating at your convenience.
• If you are building a new home: You will need to implement an all-electric solution. Reverse cycle heating and cooling is now the standard for all new constructions.
• If you are undertaking extensive renovations that require new gas lines: It is essential to consult with your builder, as certain councils are beginning to enforce restrictions on new gas installations, even in existing 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 comparison, reverse cycle systems may take longer to warm up, especially during cold mornings when your home has been chilly overnight.
• Reliable heat distribution: Efficiently designed ductwork ensures that heat is uniformly distributed throughout your home, providing comfort in every room.
• Performance in extreme cold: Gas systems maintain efficiency even when external temperatures drop significantly. While modern reverse cycle units perform well 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 choice and can often be accomplished in a single day, unlike switching to a reverse cycle system.

Compare the Advantages of Reverse Cycle Systems Against 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 supply.
• Reduced operational costs: Contemporary 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 modern reverse cycle systems enable 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 a safeguard against rising energy costs.

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

Here are realistic annual running cost estimates for a typical three-bedroom home in Melbourne during 2026, based on average occupancy:

• Annual running cost for ducted gas: This usually ranges from $1,200 to $2,000, depending on usage behaviour, energy tariffs, and the efficiency of the unit.
• Annual running cost for ducted reverse cycle: This typically 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 vital to recognise that homes with poor insulation, oversized rooms, or extensive glass features may incur higher costs within these ranges, regardless 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 less than 10 years old and performing 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 part 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 a necessity, gas might still be the more economical choice.

Recognise When 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 incorporate cooling capabilities now rather than retrofitting later.
• If you're weary of paying 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 you wish to lower energy costs: Reverse cycle systems consistently outperform ducted gas regarding running costs in Melbourne, and the gap is widening.
• If future resale value is important: 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 Eliminated in Victoria?

Not for existing homes. As of January 1, 2024, new residential constructions requiring planning permits are banned 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 choose 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 reside 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 not affected by the restrictions 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 around $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 cost of $1,500 to $2,500. Beyond offers fixed-price quotes following a complimentary in-home assessment, ensuring there are no fluctuating estimates once the work begins.

Do Reverse Cycle Systems Operate Effectively During Melbourne Winters?

Yes — modern reverse cycle units are designed to work efficiently at temperatures as low as minus five degrees Celsius, which is sufficient for Melbourne's coldest mornings. While efficiency may decrease 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 needs is far more critical than simply the choice of system.

Will Transitioning to Reverse Cycle Yield 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'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 need to juggle 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 entire installation typically 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 with your planning.
