Ducted Gas and Reverse Cycle: Melbourne Homeowners’ 2026 Choices

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 options between gas and reverse cycle heating for your Melbourne home in 2026? Let’s delve into these alternatives comprehensively and without any sales jargon, empowering you to make an informed decision.

Familiarise Yourself with Melbourne's Heating Regulations for 2026

As of January 1, 2024, the Victorian Government has enforced a gas ban on 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 governed by the Victorian Department of Energy, Environment and Climate Action and applies statewide. For comprehensive details about this policy, please refer to the Energy Victoria website.

Here’s how this policy impacts homeowners:

• If your home is gas-powered: You are not required to make immediate changes. You can continue using your current ducted gas system, replace it with another gas unit when it reaches the end of its lifespan, or 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 mandatory 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.

Explore the Benefits of Ducted Gas Heating for Melbourne Homes

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

• Rapid heating: Gas burners reach their operational temperature quickly. In contrast, reverse cycle systems might take longer to warm up, especially during chilly mornings after a cool night.
• Reliable heat distribution: Well-constructed ductwork ensures that heat is evenly distributed throughout your home, providing comfort in every room.
• Effective in extreme cold: Gas systems retain their efficiency even when outside temperatures drop significantly. While modern reverse cycle units function adequately in Melbourne’s coldest conditions, gas systems maintain a distinct advantage.
• Utilisation of existing infrastructure: If your ductwork, controls, and gas lines are in sound condition, replacing your gas unit with another ducted gas heater is often a cost-effective choice that can typically be completed in a single day, unlike transitioning to a reverse cycle system.

Compare the Advantages of Reverse Cycle Systems to Ducted Gas Heating

• Dual heating and cooling capabilities: 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 exceptionally efficient, producing three to five units of heat for each unit of electricity consumed, an efficiency level that gas systems find challenging to meet.
• No combustion emissions: Reverse cycle systems mitigate the risks associated with gas combustion, including the need for flues and concerns regarding carbon monoxide safety.
• Improved zoning options: Many contemporary reverse cycle systems permit specific rooms to be heated or cooled independently, preventing unnecessary heating in unoccupied areas.
• Future-proof investment: With gas prices in Victoria rising over the past five years, reverse cycle systems offer a buffer against increasing energy costs.

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

Here are realistic annual running cost estimates 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 five-star rated units or above.
• Cost savings: Households can anticipate savings of between $400 and $800 annually by making the switch, not including the added summer cooling that a reverse cycle system provides.

It is important to recognise that homes with inadequate insulation, oversized rooms, or extensive glass features may incur higher costs within these ranges, irrespective of the chosen 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 a Strong Option

• If your current gas system is less than 10 years old and operating well: You can replace it with a similar unit when it eventually fails, thereby maintaining an efficient asset.
• If your home has limited electrical capacity: Older homes with low-amperage supplies might require a switchboard upgrade to accommodate a ducted reverse cycle system, potentially increasing 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’s wise to assess your specific home instead of 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 not essential, gas might still be the more economical choice.

Recognise When Reverse Cycle Systems Are the Better Choice

• If your existing ducted gas unit is over 12 years old: You are nearing the end of its operational lifespan, making it more economical to incorporate cooling capabilities now rather than retrofitting later.
• 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’re 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 for 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 prioritise 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. From 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 reside in an existing home that is already connected to gas, you can replace a malfunctioning ducted gas unit with a new one. The installation must be conducted by a licensed gas fitter in accordance with AS/NZS 5601 gas installation standards, but it is not subject to 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 acceptable 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 commences.

Do Reverse Cycle Systems Perform Efficiently During Melbourne Winters?

Yes — modern reverse cycle units are designed to operate efficiently at temperatures as low as minus five degrees Celsius, which is sufficient for Melbourne's coldest mornings. While efficiency may diminish in extreme cold compared to gas, the difference is minimal for most Melbourne homes. Proper sizing of the unit based on your home’s heating requirements is more crucial than merely the choice of system.

Will Transitioning to Reverse Cycle Result in 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 currently utilise 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 handle 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 complete installation generally 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.
