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 observed a rise in your energy bills, you may be contemplating a switch. Are you evaluating whether to opt for gas or reverse cycle heating for your Melbourne home in 2026? Let’s explore these options thoroughly and without any sales jargon, enabling you to make a well-informed choice.

Understand Melbourne's Heating Regulations and Changes for 2026

From January 1, 2024, the Victorian Government has implemented a gas ban for new residential properties. This regulation mandates 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 is applicable across the state. For full details regarding this policy, please visit the Energy Victoria website.

Here’s what this policy means for homeowners:

• If your home uses gas: You are not obligated to make any immediate changes. You may continue using your existing ducted gas system, replace it with another gas unit at the end of its life, or choose to transition to reverse cycle heating at your convenience.
• If you are constructing a new home: You will be required to adopt an all-electric approach. Reverse cycle heating and cooling is now the standard for all new constructions.
• If you are undertaking significant renovations needing new gas lines: It is crucial to consult with your builder, as some councils are starting to enforce restrictions on new gas installations, even in existing homes.

Examine the Advantages of Ducted Gas Heating for Homes in Melbourne

Ducted gas heating remains a viable option for numerous households in Melbourne. Its advantages are noteworthy:

• Swift heating: Gas burners achieve their operational temperature rapidly. In contrast, reverse cycle systems may take longer to warm up, particularly during chilly mornings when your home has been cool overnight.
• Dependable heat distribution: Well-designed ductwork ensures heat is evenly distributed across all areas of your home, providing comfort in every room.
• Performance in extreme cold: Gas systems maintain their efficiency even when external temperatures plummet. Although modern reverse cycle units perform adequately in Melbourne’s coldest conditions, gas systems have a clear edge.
• Use of existing infrastructure: If your ductwork, controls, and gas lines are in good condition, replacing your gas unit with another ducted gas heater is usually a cost-effective choice and can often be completed in a single day, unlike transitioning to a reverse cycle system.

Assess the Benefits of Reverse Cycle Systems Compared to Ducted Gas

• Integrated heating and cooling: 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 offer.
• Lower operational costs: Modern reverse cycle systems are highly efficient, generating three to five units of heat for each unit of electricity consumed, an efficiency level that gas systems struggle to achieve.
• No combustion emissions: Reverse cycle systems remove the risks associated with gas combustion, including the necessity for flues and concerns regarding carbon monoxide safety.
• Enhanced zoning capabilities: Many new reverse cycle systems allow for specific rooms to be heated or cooled independently, preventing unnecessary heating in unoccupied spaces.
• Future-proof investment: With gas prices in Victoria rising over the past five years, reverse cycle systems provide a buffer against escalating energy costs.

Comparative Overview of Annual Running Costs for a Typical Three-Bedroom Home in Melbourne

Below 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 units rated five stars or above.
• Cost savings: Households can expect to save between $400 and $800 annually by making the switch, not including the added summer cooling provided by a reverse cycle system.

It is crucial to acknowledge that homes with inadequate insulation, oversized rooms, or extensive glass features may incur higher costs within these ranges, regardless of the selected heating system. Addressing draughts, insulating ceilings, and employing effective zoning strategies can significantly influence your energy bills more than the choice of heating system.

Identify Scenarios Where Ducted Gas Heating Is Still a Strong Choice

• If your current gas system is less than 10 years old and functioning well: You can replace it with a similar unit when it eventually fails, preserving an efficient asset.
• If your home has limited electrical capacity: Older homes with low-amperage supplies may need a switchboard upgrade to accommodate a ducted reverse cycle system, which can raise the overall transition cost.
• If you reside in a particularly cold region of Melbourne or regional Victoria: In frost-prone microclimates, reverse cycle systems may face challenges. It’s prudent to evaluate your specific home rather than 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 a necessity, gas might still be the more economical choice.

Recognise When Reverse Cycle Systems Are the Superior 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 incorporate cooling capabilities now rather than retrofitting later.
• If you're tired of 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 costs: Reverse cycle systems consistently outperform ducted gas in terms of running costs in Melbourne, and the disparity is widening.
• If future resale value is a consideration: Potential buyers increasingly favour energy efficiency and cooling options, where reverse cycle systems excel.

Address Common Queries Regarding Heating Solutions 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 already connected to gas can continue using their systems, replace them with new gas appliances, or voluntarily choose 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 conducted 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 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 approximately $5,500 and can exceed ,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 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 starts.

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 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 negligible. 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 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. 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 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 need to manage multiple contractors. Gas disconnection must be performed by a Type A gas fitter in alignment 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 usually 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.
