Ducted Gas and Reverse Cycle: Melbourne’s 2026 Heating Options

If your gas ducted heating system is operational but emitting unusual sounds or if you’ve observed a spike in your energy bills, you might be considering whether it’s time for an upgrade. Are you deciding between gas or reverse cycle heating for your Melbourne home in 2026? Let’s clarify these heating options without any sales jargon, empowering you to make a well-informed decision.

Explore Melbourne’s Heating Regulations and Their Implications for 2026

Starting January 1, 2024, the Victorian Government has enacted a gas ban for new residential constructions. This regulation mandates that any new homes requiring planning permits cannot connect to mains gas and must use all-electric systems instead. This initiative is overseen by the Victorian Department of Energy, Environment and Climate Action and applies statewide. For detailed policy information, please visit the Energy Victoria website.

The implications of this policy for homeowners are as follows:

• If your home currently uses gas: There are no immediate changes required. You can 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 convenience.
• If you are building a new home: You will need to adopt an all-electric approach. Reverse cycle heating and cooling has become the standard for all new constructions.
• If you are planning major renovations that include new gas lines: It is essential to consult with your builder, as some councils are enforcing restrictions on new gas installations, even in existing homes.

Discover the Benefits of Ducted Gas Heating for Melbourne Homes

Ducted gas heating continues to be a practical option for many households in Melbourne, providing several significant advantages:

• Quick heating: Gas burners can reach their operating temperature rapidly. In contrast, reverse cycle systems may take longer to warm up, especially on chilly mornings when your home has been cold overnight.
• Even heat distribution: Well-designed ductwork ensures that heat is evenly spread throughout every room of your home, maintaining comfort in all areas.
• Efficiency in extreme cold: Gas systems remain effective even in significantly low external temperatures. While modern reverse cycle units perform adequately in Melbourne’s coldest conditions, gas systems still 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 more cost-effective and can often be completed within a day, compared to transitioning to a reverse cycle system.

Evaluate the Advantages of Reverse Cycle Systems Compared to Ducted Gas Heating

• Combined heating and cooling: A reverse cycle system offers warmth in winter and cooling in summer, eliminating the need for a separate cooling system, which is not the case with ducted gas.
• Reduced running costs: Modern reverse cycle systems are highly efficient, providing 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 worries regarding carbon monoxide safety.
• Improved zoning capabilities: Many contemporary reverse cycle systems allow for individual heating or cooling of specific rooms, avoiding unnecessary heating in unoccupied spaces.
• Future-proof investment: With gas prices in Victoria steadily increasing over the past five years, reverse cycle systems provide protection against rising energy costs.

In-Depth Comparison of Operating Costs for a Standard Three-Bedroom Home in Melbourne

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

• Annual running cost for ducted gas: This can range from $1,200 to $2,000, influenced by usage patterns, energy rates, and the efficiency of the heating unit.
• Annual running cost for ducted reverse cycle: This generally falls between $700 to $1,400 for a unit rated five stars or higher.
• Cost savings: Households can anticipate savings of between $400 and $800 annually by switching, not including the added summer cooling provided by a reverse cycle system.

It’s important to note that homes with inadequate insulation, oversized spaces, or extensive glass features may incur higher costs within these estimates, regardless of the heating system chosen. Addressing draughts, insulating ceilings, and using effective zoning strategies can significantly impact your energy bills more than the choice of heating system.

Recognise Scenarios Where Ducted Gas Heating Remains a Suitable Option

• If your current gas system is less than 10 years old and operating efficiently: You may replace it with a similar unit when it ultimately fails, ensuring ongoing efficiency.
• 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 could 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 face challenges. Assessing your specific home conditions is crucial rather than relying solely on general advice.
• If you only need heating without cooling: A new ducted gas unit typically has a lower initial cost compared to a ducted reverse cycle system. If cooling is not a priority, gas may still be the more economical choice.

Identify When Reverse Cycle Systems Are the Superior Option

• If your existing ducted gas unit is over 12 years old: You are nearing the end of its operational life, making it more cost-effective to incorporate 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 time allows for a well-designed system instead of a makeshift solution.
• If you aim for reduced energy costs: Reverse cycle systems consistently outperform ducted gas in terms of running costs in Melbourne, with the gap widening over time.
• If future resale value is important: Prospective buyers increasingly favour energy efficiency and cooling options, where reverse cycle systems excel.

Address Frequently Asked Questions About Heating Options in Melbourne

Is Gas Heating Being Phased Out in Victoria?

No, existing homes are unaffected. 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 choose to adopt electric systems voluntarily. 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 already connected to gas, you can replace a malfunctioning 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 impacted 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 reasonable condition, installing a ducted reverse cycle system starts at around $5,500 and can exceed $15,000 for larger homes with multiple zones or premium units. If an upgrade to your switchboard is necessary to manage the load, you should expect an additional cost ranging from $1,500 to $2,500. Beyond provides fixed-price quotes following a complimentary in-home assessment, ensuring no unexpected 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, the difference for most Melbourne homes is minimal. Proper sizing of the unit based on your home’s heating needs is more critical than merely the choice of system.

Will Switching to Reverse Cycle Lead to Real Savings?

Most households in Melbourne can expect to save between $400 and $800 annually on running costs when moving from ducted gas to ducted reverse cycle, assuming similar usage patterns. The potential savings could be even greater if you are currently maintaining separate heating and cooling systems, as one ducted reverse cycle unit can replace both, eliminating the costs associated with operating a second system.

Do I Need to Hire Both an Electrician and a Gas Fitter for the Transition?

Yes — a licensed gas fitter is required 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 deal with multiple contractors. Gas disconnection must be performed by a Type A gas fitter in line with Energy Safe Victoria regulations.

What Is the Typical Timeline for Installing 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 replacement or reconfiguration of the existing ductwork is necessary, or if the switchboard needs upgrading, allow for a timeframe of two to three days. We provide a detailed schedule as part of the quote to assist in your planning.
