Ducted Gas and Reverse Cycle: Melbourne Homeowners’ Choices 2026

If your gas ducted heating system operates but emits unusual noises or if you have 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 home in 2026? Let’s delve into these options comprehensively, allowing you to make a well-informed decision.

Explore Melbourne's Heating Regulations and Anticipated Changes for 2026

As of January 1, 2024, the Victorian Government has introduced a gas ban for new residential constructions. This regulation stipulates that any new homes requiring planning permits cannot connect 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 information about this policy, please visit the Energy Victoria website.

The implications of this policy for homeowners are as follows:

• If your home relies on gas: You are not required to make immediate changes. You may continue using your existing ducted gas system, replace it with another gas unit when it reaches the end of its lifespan, or choose to transition to reverse cycle heating at your discretion.
• If you are building a new home: You will need to adopt an all-electric solution. Reverse cycle heating and cooling has become the standard for all new constructions.
• If you are undergoing significant renovations that require 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 homes.

Evaluate the Benefits of Ducted Gas Heating for Melbourne Homes

Ducted gas heating continues to be a valid choice for many households in Melbourne. Its benefits are substantial:

• Rapid heating: Gas burners reach their operational temperature quickly. In comparison, reverse cycle systems may require more time to warm up, particularly during those chilly mornings when your home has been cool overnight.
• Consistent heat distribution: Well-designed ductwork ensures that heat is effectively distributed throughout your home, delivering comfort in every room.
• Effective in extreme cold: Gas systems maintain their performance even when outside temperatures drop significantly. While modern reverse cycle units are competent in Melbourne's coldest conditions, 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 generally a cost-effective option and can often be completed in a single day, unlike the transition to a reverse cycle system.

Compare the Advantages of Reverse Cycle Systems Against Ducted Gas

• Dual heating and cooling: A reverse cycle system offers warmth in winter and cooling in summer, eliminating the need for a separate cooling system that ducted gas does not provide.
• Reduced operating 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 often cannot match.
• No combustion emissions: Reverse cycle systems eliminate the risks linked to gas combustion, including the need for flues and concerns about carbon monoxide safety.
• Improved zoning functionality: Many new reverse cycle systems allow for independent heating or cooling of specific rooms, preventing unnecessary heating in unoccupied areas.
• Future-proof investment: With gas prices in Victoria increasing over the past five years, reverse cycle systems serve as a buffer against rising energy costs.

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

Below are estimated 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, 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 higher.
• Cost savings: Households can anticipate savings of between $400 and $800 annually by switching, not accounting for the additional summer cooling provided by a reverse cycle system.

It is important to recognise that homes with inadequate insulation, excessively large rooms, or extensive glass features may experience higher costs within these ranges, irrespective of the selected heating system. Addressing draughts, insulating ceilings, and implementing effective zoning strategies can significantly impact your energy bills more than the choice of heating system.

Identify Scenarios Where Ducted Gas Heating Remains an Excellent Choice

• If your current gas system is less than 10 years old and in good working order: You can replace it with a similar unit when it eventually fails, preserving 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, potentially increasing the overall transition costs.
• 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 purely on general advice.
• 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 essential, gas could still be the more economical option.

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 cost-effective to incorporate cooling capabilities now rather than retrofitting in the future.
• If you’re weary of 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 facilitates a well-designed system instead of a temporary solution.
• If you aim to reduce energy costs: Reverse cycle systems consistently outperform ducted gas in terms of running costs in Melbourne, and this gap is widening.
• If future resale value is a consideration: Potential buyers increasingly prioritise energy efficiency and cooling options, where reverse cycle systems excel.

Address Frequently Asked 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 cannot connect 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 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 performed 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 begins 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 commences.

Do Reverse Cycle Systems Operate Efficiently During Melbourne Winters?

Yes — modern reverse cycle units are engineered to work efficiently at temperatures as low as minus five degrees Celsius, which is adequate 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 requirements is more critical than merely the choice of system.

Will Transitioning to Reverse Cycle Yield Real 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 utilising 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 necessary switchboard upgrades. Beyond coordinates both trades as part of a comprehensive installation, so you won’t have to juggle multiple contractors. Gas disconnection must be carried out 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 complete 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.
