Preferences of Melbourne Homeowners: Ducted Gas vs Reverse Cycle 2026

If your gas ducted heating system is operational but producing unusual noises or if you've noticed an increase in your energy bills, you might be considering a change. Are you deliberating between gas and reverse cycle heating for your Melbourne home in 2026? Let’s delve into these options thoroughly, allowing you to arrive at an informed decision without any sales jargon.

Explore Melbourne's Heating Regulations and Changes for 2026

As of January 1, 2024, the Victorian Government has enacted a gas ban for all new residential properties. This regulation stipulates that any new homes requiring planning permits cannot connect to mains gas and must implement all-electric systems. This initiative, enforced by the Victorian Department of Energy, Environment and Climate Action, applies statewide. For comprehensive information regarding this policy, please visit the Energy Victoria website.

Here’s what this policy entails for homeowners:

• If your home currently uses gas: You are under no obligation to make immediate changes. You can continue using your existing ducted gas system, replace it with another gas unit when it reaches the end of its lifespan, or transition to reverse cycle heating at your convenience.
• If you are building a new home: An all-electric approach is mandatory. Reverse cycle heating and cooling now represents the standard for all new constructions.
• If you are undertaking major 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.

Evaluate the Advantages of Ducted Gas Heating for Melbourne Homes

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

• Rapid heating: Gas burners reach their operational temperature swiftly. In comparison, reverse cycle systems may take longer to warm up, especially during chilly mornings when your home has been cool overnight.
• Reliable heat distribution: Well-designed ductwork ensures that heat is evenly spread throughout your home, providing comfort in every room.
• Effective in extreme cold: Gas systems retain their efficiency even when external temperatures drop significantly. While modern reverse cycle units perform adequately in Melbourne’s coldest conditions, gas systems maintain a clear 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 tends to be a cost-effective option and can usually be completed in a single day, unlike the transition to a reverse cycle system.

Investigate the Benefits of Reverse Cycle Systems Compared to Ducted Gas

• Combined heating and cooling: A reverse cycle system provides warmth during winter and cooling in summer, eliminating the need for a separate cooling system that ducted gas cannot offer.
• Reduced operational costs: Modern reverse cycle systems are highly efficient, producing three to five units of heat for each unit of electricity consumed, which is an efficiency level 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 concerns regarding carbon monoxide safety.
• Improved 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 offer a safeguard against increasing energy costs.

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

Below 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 falls between $1,200 and $2,000, depending on usage patterns, energy tariffs, and the efficiency of the unit.
• Annual running cost for ducted reverse cycle: This generally ranges from 0 to strong,400 for units rated five stars or higher.
• Cost savings: Households can anticipate saving between $400 and $800 annually by making the switch, without considering the additional cooling provided by a reverse cycle system.

It is important to recognise that homes with insufficient insulation, oversized rooms, or extensive glass features may experience higher costs within these ranges, regardless of the heating system selected. Addressing draughts, insulating ceilings, and employing 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 efficiently: You can replace it with a similar unit when it eventually fails, maintaining an effective asset.
• If your home has limited electrical capacity: Older properties with low-amperage supplies may 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 advisable to assess your specific home rather than relying solely on general information.
• If heating is your only requirement without cooling: A new ducted gas unit typically incurs a lower initial cost compared to a ducted reverse cycle system. If cooling is unnecessary, gas may still be the more economical option.

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 operational life, making it more cost-effective to incorporate cooling capabilities now rather than retrofitting later.
• If you wish to avoid 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 rather than a makeshift solution.
• If you aim for lower energy costs: Reverse cycle systems consistently outperform ducted gas in running costs in Melbourne, and the gap is widening.
• If you are considering future resale value: 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 choose electric systems voluntarily. The ban specifically impacts 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 that is already connected to gas, you can replace a failing 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 affected by the bans on new constructions.

What Are the Costs Associated with Switching from Ducted Gas to Reverse Cycle in Melbourne?

For a standard three-bedroom home in Melbourne with existing ductwork in satisfactory condition, the installation of a ducted reverse cycle system begins 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 required to manage the load, expect 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, suitable for Melbourne's coldest mornings. While efficiency may decrease in extreme cold compared to gas, for most Melbourne homes, the difference is minimal. 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 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 are 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 have to manage multiple contractors. Gas disconnection must be carried out by a Type A gas fitter following 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 usually takes one to two days. If the existing ductwork requires replacement or reconfiguration, or if the switchboard needs upgrading, anticipate a timeframe of two to three days. We provide a detailed schedule as part of the quote to assist in your planning.
