Ducted Gas vs Reverse Cycle: Preferences of Melbourne Homeowners 2026

Your gas ducted heating system is still operational, but perhaps it's emitting unusual sounds, and your energy bills are escalating. You might be contemplating whether a change is necessary. Should you choose gas or reverse cycle for your Melbourne home in 2026? Let’s explore the options candidly, without any sales jargon.

Understanding Melbourne's Heating Landscape in 2026

As of 1 January 2024, the Victorian Government has implemented a gas ban for new homes. This regulation dictates that any new residential construction requiring planning permits cannot connect to mains gas and must instead opt for all-electric systems. This policy is set by the Victorian Department of Energy, Environment and Climate Action and is applicable throughout the state. You can find the complete policy details on the Energy Victoria website.

Here’s what this means for you:

• If your home is already connected to gas: You are not obligated to switch. You can continue using your ducted gas system, replace it with another gas unit when it reaches the end of its life, or choose to transition to reverse cycle heating at your discretion.
• If you are constructing a new home: You will automatically be going all-electric. Reverse cycle heating and cooling is now the standard for new constructions.
• If you are undertaking significant renovations that involve new gas lines: Consult with your builder — certain councils now impose restrictions on new gas installations, even in existing homes.

The Advantages of Ducted Gas Heating

Ducted gas heating remains a viable option for many Melbourne homes. Its benefits continue to be relevant:

• Rapid heating: Gas burners reach their operating temperature swiftly. In contrast, reverse cycle systems may take longer to warm up, particularly on cold mornings when your home has been chilly overnight.
• Consistent heat distribution: Well-designed ductwork ensures that heat is evenly distributed across all zones of your home.
• Effective performance in extreme cold: Gas systems maintain their efficiency even when outdoor temperatures plummet. While modern reverse cycle units perform adequately in Melbourne's coldest weather, gas systems have a clear advantage.
• Existing infrastructure: If your ductwork, controls, and gas line are all in good condition, replacing your gas unit with another ducted gas heater is typically a more economical, one-day job compared to switching to a reverse cycle system.

Key Benefits of Reverse Cycle Systems Over Ducted Gas

• Heating and cooling combined: A reverse cycle system provides both warmth in winter and cooling in summer, eliminating the need for a separate cooling system like ducted gas does.
• Lower operational costs: Modern reverse cycle systems are highly efficient, generating three to five units of heat for every unit of electricity consumed. Gas systems cannot match this efficiency.
• No combustion emissions: Reverse cycle systems eliminate the risks associated with gas combustion, including flue requirements and carbon monoxide safety concerns.
• Smart zoning capabilities: Many contemporary reverse cycle systems allow you to heat or cool specific rooms independently, meaning you’re not paying to heat an unused bedroom.
• Future-proof investment: With gas prices in Victoria trending upwards over the past five years, reverse cycle systems provide insulation against rising energy costs.

Comparing Running Costs for a Typical Melbourne Three-Bedroom Home

Here are the realistic annual running cost estimates for a standard three-bedroom home in Melbourne during 2026, assuming normal occupancy:

• Annual running cost for ducted gas: Ranges from $1,200 to $2,000, influenced by usage patterns, energy tariffs, and unit efficiency.
• Annual running cost for ducted reverse cycle: Between $700 and $1,400 for a unit rated 5 stars or better.
• Cost savings: Households can save between $400 and $800 annually by making the switch, not accounting for the added summer cooling provided by a reverse cycle system.

Keep in mind: homes that are poorly insulated, oversized, or have extensive glass features may incur higher costs within these ranges, regardless of the system used. Addressing draughts, insulating ceilings, and implementing proper zoning can significantly impact your energy bills more than the choice of system alone.

When 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 require a switchboard upgrade to accommodate a ducted reverse cycle system, increasing the overall cost of the transition.
• If you reside in an exceptionally cold area of Melbourne or regional Victoria: In frost-prone microclimates, reverse cycle systems may struggle. It’s advisable to model your specific home rather than rely solely on general information.
• If you only need heating and not cooling: A new ducted gas unit typically has a lower initial cost than a ducted reverse cycle system. If cooling is not a concern, gas may still be the more economical choice.

When Reverse Cycle Systems Are the Superior Option

• If your existing ducted gas unit is over 12 years old: You’re nearing the end of its lifespan anyway. Adding cooling capabilities at this stage is much cheaper than retrofitting later.
• If you're tired of incurring separate summer cooling costs: Ditching multiple systems like split units or evaporative cooling in favour of one ducted reverse cycle system streamlines your setup and reduces costs.
• If you’re renovating or extending your home: Installing new ductwork simultaneously allows for a properly designed system rather than a makeshift solution.
• If you desire lower energy bills: Reverse cycle systems have consistently outperformed ducted gas in terms of running costs in Melbourne, and the gap continues to widen.
• If you're considering future resale value: Prospective buyers increasingly prioritise energy efficiency and cooling options, where reverse cycle systems excel.

Common Questions About Heating Options in Melbourne

Is Gas Heating Being Phased Out in Victoria?

Not for current homes. As of 1 January 2024, new residential constructions requiring planning permits cannot connect to mains gas and must switch to all-electric systems. existing gas-connected homes can continue using their gas systems, replace them with new gas appliances, or opt for 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 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 compliance with AS/NZS 5601 gas installation standards, but it is not affected by the bans on new builds.

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 fair condition, installing a ducted reverse cycle system starts around $9,500 and can exceed $15,000 for larger homes with multiple zones or premium units. If an upgrade to your switchboard is necessary to accommodate the load, expect an additional cost of $1,500 to $2,500. Beyond provides fixed-price quotes following a free in-home assessment — no fluctuating estimates once the work begins.

Do Reverse Cycle Systems Function Well During Melbourne Winters?

Yes — modern reverse cycle units operate efficiently at temperatures as low as minus five degrees Celsius, which is adequate for Melbourne's chilliest mornings. While output may decrease in extreme cold compared to gas, for most Melbourne homes, the difference is negligible. Proper sizing of the unit based on your home’s heating needs is more crucial than the choice of system.

Will Switching to Reverse Cycle Result in Actual Savings?

Most households in Melbourne can expect to save between $400 and $800 annually on running costs when transitioning from ducted gas to ducted reverse cycle, assuming similar usage patterns. The potential savings are even greater if you're currently using separate heating and cooling systems, as one ducted reverse cycle unit can replace both, eliminating the cost of the second system.

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

Yes — a licensed gas fitter is required to disconnect and safely cap the old gas line, while a licensed electrician will handle the electrical work 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 under Energy Safe Victoria regulations.

What Is the Installation Timeframe for a Reverse Cycle Ducted System?

For a typical 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 an upgrade, plan for two to three days. We provide a detailed timeline as part of the quote to help you plan accordingly.
