Ducted Gas and Reverse Cycle Preferences Among Melbourne Homeowners

If your gas ducted heating system is operational but emitting unusual sounds or if you've noticed an increase in your energy bills, you might be considering a change. Are you pondering whether to choose gas or reverse cycle heating for your Melbourne home in 2026? Let’s delve into these options in detail, free of marketing jargon, to assist you in making an informed decision.

Navigate Melbourne's Heating Regulations and Upcoming Changes for 2026

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

Here’s the implication of this policy for homeowners:

• If your home relies on gas: You are not required to make any immediate adjustments. You may continue using your existing ducted gas system, replace it with another gas unit when it reaches the end of its life, or opt to transition to reverse cycle heating at your convenience.
• If you are building a new home: You must adopt an all-electric approach. Reverse cycle heating and cooling is now standard for all new constructions.
• If you are undertaking major renovations that necessitate new gas lines: It is essential to consult with your builder, as some councils are starting to enforce restrictions on new gas installations, even in existing homes.

Explore the Benefits of Ducted Gas Heating for Melbourne Residents

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

• Rapid heating: Gas burners reach their operational temperature swiftly. In contrast, reverse cycle systems may take longer to warm up, especially during cold mornings when your home has been cool overnight.
• Reliable heat distribution: Well-constructed ductwork guarantees that heat is evenly spread throughout your home, ensuring comfort in every room.
• Effective in extreme cold: Gas systems retain their efficiency even when outside temperatures plummet. Although modern reverse cycle units perform adequately in Melbourne’s chilliest conditions, gas systems have a distinct advantage.
• Utilisation of existing infrastructure: If your ductwork, controls, and gas lines are in good condition, swapping your gas unit for another ducted gas heater is typically a cost-effective option that can often be completed in a day, unlike the transition to a reverse cycle system.

Evaluate the Benefits of Reverse Cycle Systems Over Ducted Gas Heating

• Combined heating and cooling: A reverse cycle system provides warmth in winter and cooling in summer, eliminating the need for a standalone cooling system that ducted gas does not offer.
• Reduced operational costs: Contemporary reverse cycle systems are highly efficient, producing three to five units of heat for each unit of electricity consumed, a level of efficiency that gas systems find difficult to achieve.
• Absence of combustion emissions: Reverse cycle systems mitigate the risks associated with gas combustion, including the need for flues and concerns surrounding carbon monoxide safety.
• Improved zoning capabilities: Many modern reverse cycle systems permit specific rooms to be heated or cooled independently, avoiding unnecessary heating in unoccupied areas.
• Future-proof investment: With gas prices in Victoria rising over the past five years, reverse cycle systems offer a safeguard against escalating energy costs.

Annual Running Cost Comparison for a Typical Three-Bedroom Home in Melbourne

Here are realistic annual running cost estimates for a standard three-bedroom home in Melbourne for 2026, based on 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 higher.
• Cost savings: Households can expect to save between $400 and $800 annually by making the switch, not including the additional summer cooling provided by a reverse cycle system.

It is important to recognise that homes with poor insulation, oversized rooms, or extensive glass features may incur higher costs within these ranges, regardless of the chosen heating system. Tackling draughts, insulating ceilings, and implementing effective zoning strategies can significantly affect your energy bills more than the choice of heating system.

Identify Scenarios Where Ducted Gas Heating Remains a Strong Choice

• 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 efficient asset.
• If your home has limited electrical capacity: Older houses 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 encounter challenges. It’s wise 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 not a necessity, gas might still be the more economical option.

Recognise When Reverse Cycle Systems Offer Superior Benefits

• If your existing ducted gas unit is over 12 years old: You are nearing the end of its lifespan, making it more cost-effective to include cooling capabilities now rather than retrofitting later.
• If you're weary of separate summer cooling costs: Transitioning from multiple systems such as split units or evaporative cooling to a single ducted reverse cycle system simplifies 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 stopgap solution.
• If you aim to reduce energy costs: 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 prioritise energy efficiency and cooling options, where reverse cycle systems excel.

Address Common Questions About Heating Solutions in Melbourne

Is Gas Heating Being Phased Out in Victoria?

Not for existing homes. As of January 1, 2024, new residential properties 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 opt for 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 substitute 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 Transitioning 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 $10,000 for larger homes with multiple zones or premium units. If an upgrade to your switchboard is necessary to manage the load, anticipate an additional 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, which is suitable for Melbourne's coldest mornings. While efficiency may decline in extreme cold compared to gas, for the majority of Melbourne homes, the difference is minimal. Proper sizing of the unit based on your home’s heating requirements is more crucial than merely the choice of system.

Will Transitioning to Reverse Cycle Result in Tangible Savings?

Most households in Melbourne can anticipate saving between $400 and $800 annually on running costs when transitioning 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 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 need to deal with multiple contractors. Gas disconnection must be performed 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, expect a timeframe of two to three days. We provide a detailed schedule as part of the quote to assist in your planning.
