Ducted Gas and Reverse Cycle: Melbourne Homeowners’ Choices 2026

If your gas ducted heating system is operational yet producing unusual sounds, or if you've noticed an increase in your energy bills, you might be considering a change. Are you deciding between gas and reverse cycle heating for your Melbourne home in 2026? Let’s delve into these options comprehensively and in straightforward terms, empowering you to make an informed decision.

Comprehend Melbourne's Heating Regulations and Changes for 2026

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

Here’s the significance of this policy for homeowners:

• If your home uses gas: You are under no obligation to make immediate changes. You can continue using your current ducted gas system, replace it with another gas unit once it reaches the end of its life, or transition to reverse cycle heating at your convenience.
• If you are building a new home: You must adopt an all-electric strategy. Reverse cycle heating and cooling is now the standard requirement for all new constructions.
• If you are undertaking significant renovations requiring new gas lines: It is vital to consult with your builder, as some councils are beginning to implement restrictions on new gas installations, even within existing homes.

Evaluate the Benefits of Ducted Gas Heating for Melbourne Homes

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

• Rapid heating: Gas burners reach their operational temperature swiftly. In contrast, reverse cycle systems may require more time to warm up, particularly during chilly mornings when your home has been cold overnight.
• Reliable heat distribution: Well-designed ductwork ensures that heat is evenly distributed throughout your home, providing comfort in every room.
• Performance in extreme cold: Gas systems retain their efficiency even when external temperatures fall drastically. While modern reverse cycle units function 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 is often a cost-effective option and can frequently be completed in a single day, unlike a switch to a reverse cycle system.

Compare the Advantages of Reverse Cycle Systems 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 include.
• Reduced operational costs: Modern reverse cycle systems are highly efficient, producing three to five units of heat for each unit of electricity consumed, an efficiency level that gas systems struggle to match.
• No combustion emissions: Reverse cycle systems mitigate the risks associated with gas combustion, including the need for flues and concerns related to carbon monoxide safety.
• Enhanced zoning capabilities: Many new reverse cycle systems allow for individual 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 buffer against increasing energy costs.

Annual Running Cost Comparison 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 factoring in the additional summer cooling provided by a reverse cycle system.

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

Identify Situations Where Ducted Gas Heating Remains a Strong Option

• If your current gas system is under 10 years old and performing 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, which can 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 has a lower initial cost compared to a ducted reverse cycle system. If cooling is unnecessary, gas might still be the more economical option.

Recognise When Reverse Cycle Systems Are the Optimal Choice

• If your existing ducted gas unit is over 12 years old: You are nearing the end of its operational lifespan, making it more cost-effective to incorporate cooling capabilities now rather than retrofitting later.
• If you're weary of separate summer cooling costs: Transitioning from multiple systems like 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 makeshift solution.
• If you aim for reduced 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 a factor: Potential buyers increasingly favour energy efficiency and cooling options, where reverse cycle systems excel.

Address Frequently Asked 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 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 targets 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 performed 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 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 $10,000 for larger homes with multiple zones or premium units. If an upgrade to your switchboard is necessary to handle 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 suitable for Melbourne's coldest mornings. While efficiency may decrease 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 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?
