Ducted Gas and Reverse Cycle: Preferences of Melbourne Homeowners 2026

If your gas ducted heating system is functioning but producing strange noises or if you’ve noticed a rise in your energy bills, it may be time to consider your options. Are you contemplating whether to select gas or reverse cycle heating for your Melbourne home in 2026? Let’s explore these choices transparently and without any sales jargon, empowering you to make an informed decision.

Understand Melbourne’s Heating Regulations and Their Impact in 2026

Starting January 1, 2024, the Victorian Government has implemented a gas ban for new homes. This regulation requires that any new residential constructions needing planning permits cannot connect to mains gas and must adopt all-electric systems instead. This policy, managed by the Victorian Department of Energy, Environment and Climate Action, applies throughout the state. For comprehensive policy details, visit the Energy Victoria website.

Here’s what this policy means for homeowners:

• If your home currently relies on gas: You are not obligated to make immediate changes. You can continue using your existing ducted gas system, replace it with another gas unit when it eventually fails, or choose to switch to reverse cycle heating at your convenience.
• If you are constructing a new home: You must adopt an all-electric approach. Reverse cycle heating and cooling is now the standard for all new builds.
• If you are undertaking significant renovations that involve new gas lines: Consulting with your builder is crucial, as some councils are enforcing restrictions on new gas installations, even in existing homes.

Examine the Advantages of Ducted Gas Heating in Melbourne

Ducted gas heating remains a viable option for many households in Melbourne. Its advantages continue to be substantial:

• Rapid heating: Gas burners can reach their operational temperature quickly. In contrast, reverse cycle systems may take longer to warm up, particularly on chilly mornings when your home has been cold overnight.
• Consistent heat distribution: Well-designed ductwork ensures that heat is evenly distributed throughout all areas of your home, providing comfort in every room.
• Excellent performance in low temperatures: Gas systems maintain efficiency even in significantly cold conditions. While contemporary reverse cycle units perform adequately in Melbourne’s coldest weather, gas systems have a distinct advantage.
• Leveraging existing infrastructure: If your ductwork, controls, and gas lines are well-maintained, replacing your gas unit with another ducted gas heater is usually a more economical option and can often be completed in a single day compared to switching to a reverse cycle system.

Assess the Benefits of Reverse Cycle Systems Compared to Ducted Gas

• Dual heating and cooling: A reverse cycle system provides warmth during winter and cooling in summer, eliminating the need for a separate cooling system, unlike ducted gas heating.
• Lower operational costs: Modern reverse cycle systems are highly efficient, generating three to five units of heat for every unit of electricity used, a level of efficiency that gas systems cannot achieve.
• No combustion emissions: Reverse cycle systems remove the risks associated with gas combustion, including the need for flues and concerns regarding carbon monoxide safety.
• Enhanced zoning capabilities: Many modern reverse cycle systems allow for independent heating or cooling of specific rooms, preventing unnecessary heating in spaces that are not in use.
• Future-proof investment: With gas prices in Victoria rising over the past five years, reverse cycle systems provide a buffer against increasing energy costs.

Cost Comparison for Heating a Typical Three-Bedroom Home in Melbourne

Here are estimated annual running costs for a standard three-bedroom home in Melbourne during 2026, based on 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 usually falls between $700 and $1,400 for a unit rated five stars or higher.
• Cost savings: Households can expect to save between $400 and $800 annually by making the switch, not accounting for the added summer cooling provided by a reverse cycle system.

It is important to consider 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 implementing effective zoning strategies can significantly impact your energy bills more than the choice of heating system.

Identify Situations Where Ducted Gas Heating Remains a Viable Choice

• If your current gas system is under 10 years old and functioning 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 need a switchboard upgrade to support a ducted reverse cycle system, which can raise the overall transition cost.
• If you reside in a particularly cold area of Melbourne or regional Victoria: In frost-prone microclimates, reverse cycle systems may struggle. It is essential to evaluate your specific home rather than relying solely on general information.
• If heating is your only requirement and cooling is unnecessary: A new ducted gas unit typically has a lower initial cost compared to a ducted reverse cycle system. If cooling is not a concern, gas may 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 approaching the end of its lifespan, making it more economical to add cooling capabilities now rather than retrofitting later.
• If you’re tired of incurring separate summer cooling costs: Moving from multiple systems like split units or evaporative cooling to a single ducted reverse cycle system streamlines 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 aim for lower energy expenses: Reverse cycle systems consistently outperform ducted gas in terms of 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.

Clarifying Common Questions About Heating Choices 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 prohibited from connecting to mains gas and must transition to all-electric systems. Homes that are 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 failing ducted gas unit with a new one. The installation must be performed by a licensed gas fitter in line with AS/NZS 5601 gas installation standards, and 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 acceptable condition, installing a ducted reverse cycle system starts at approximately $5,500 and can exceed $15,000 for larger homes with multiple zones or high-end units. If an upgrade to your switchboard is necessary to manage the load, you should 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 engineered to operate efficiently at temperatures as low as minus five degrees Celsius, which is sufficient for Melbourne’s coldest mornings. While efficiency may decline in extreme cold compared to gas, for most Melbourne homes, the difference is negligible. Properly sizing the unit according to your home’s heating requirements is more critical than merely choosing a system.

Will Transitioning to Reverse Cycle Result in Actual 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. The potential savings could be even greater if you currently rely on separate heating and cooling systems, as one ducted reverse cycle unit can replace both, eliminating the expenses associated with maintaining a second system.

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

Yes — a licensed gas fitter is crucial for disconnecting and safely capping the old gas line, while a licensed electrician will handle 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 manage multiple contractors. Gas disconnection must be conducted 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 requires replacement or reconfiguration, or if the switchboard needs upgrading, plan for a timeframe of two to three days. We provide a detailed schedule as part of the quote to assist in your planning.
