Preferences of Melbourne Homeowners for Ducted Gas and Reverse Cycle 2026

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 weighing the benefits of gas versus reverse cycle heating for your Melbourne home in 2026? Let’s delve into these options in detail, ensuring you make an informed decision without any commercial bias.

Comprehend Melbourne's Heating Regulations and Changes for 2026

Starting January 1, 2024, the Victorian Government has enacted a gas ban for newly constructed residential properties. This regulation stipulates that any new homes requiring planning permits cannot connect to mains gas and must instead implement all-electric systems. This policy is enforced by the Victorian Department of Energy, Environment and Climate Action and is applicable throughout the state. To explore this policy in greater detail, please visit the Energy Victoria website.

Here’s what this policy signifies for homeowners:

• If your home employs gas: You are not required to make immediate alterations. You can continue using your existing ducted gas system, replace it with another gas unit when it reaches the end of its lifespan, or opt for reverse cycle heating at a time that suits you.
• If you are building a new home: An all-electric approach is mandatory. Reverse cycle heating and cooling has become the standard for all new constructions.
• If you are engaged in significant renovations that require new gas lines: It is essential to consult with your builder, as some councils are beginning to impose restrictions on new gas installations, even in existing properties.

Evaluate the Benefits of Ducted Gas Heating for Melbourne Homes

Ducted gas heating continues to be a suitable option for many households in Melbourne. Its advantages warrant consideration:

• Rapid heating: Gas burners quickly reach their operational temperature. In contrast, Reverse cycle systems may take longer to warm up, particularly during frosty mornings when your home has been cold overnight.
• Reliable heat distribution: Well-designed ductwork guarantees that heat is evenly distributed throughout your home, ensuring comfort in every room.
• Efficiency in extreme cold: Gas systems maintain their efficiency even in subzero temperatures. While modern reverse cycle units perform adequately in Melbourne’s chilliest conditions, gas systems generally have a discernible 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, typically completed within a day, unlike the transition to a reverse cycle system.

Compare the Advantages of Reverse Cycle Systems with Ducted Gas

• Dual heating and cooling: A reverse cycle system provides warmth in winter and cooling in summer, negating the need for a separate cooling system that ducted gas cannot provide.
• Reduced operating costs: Modern reverse cycle systems exhibit high efficiency, producing three to five units of heat for every unit of electricity consumed, a level of efficiency that gas systems struggle to match.
• Absence of combustion emissions: Reverse cycle systems eliminate the hazards associated with gas combustion, including the need for flues and concerns regarding carbon monoxide safety.
• Improved zoning capabilities: Many contemporary reverse cycle systems allow for individual room heating or cooling, preventing 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 increasing energy costs.

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

Here are realistic annual running cost estimates for a standard three-bedroom home in Melbourne throughout 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 unit’s efficiency.
• 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 anticipate annual savings of between $400 and $800 by switching, not including the additional summer cooling provided by a reverse cycle system.

It is important to note 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.

Recognise 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, preserving an effective 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 elevate the overall transition cost.
• If you live in a particularly cold region 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 necessity without cooling: A new ducted gas unit often has a lower initial cost compared to a ducted reverse cycle system. If cooling is not a requirement, gas might still be the more economical choice.

Identify When Reverse Cycle Systems Are the Superior Option

• If your existing ducted gas unit is over 12 years old: You are nearing the end of its useful life, making it more economical to integrate cooling capabilities now rather than retrofitting later.
• If you're weary of 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 now allows for a well-planned system instead of a makeshift solution.
• If you aim to lower energy costs: Reverse cycle systems consistently outperform ducted gas in running costs in Melbourne, and this gap is widening.
• If future resale value is a consideration: Potential buyers increasingly prefer energy-efficient options that provide cooling, 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 opt for 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 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 compliance with AS/NZS 5601 gas installation standards, but it is not affected by the bans on new constructions.

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

For a typical three-bedroom home in Melbourne with existing ductwork in good 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, expect 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 commences.

Do Reverse Cycle Systems Operate Efficiently During Melbourne Winters?

Yes — modern reverse cycle units are engineered to function efficiently at temperatures as low as minus five degrees Celsius, which is suitable for Melbourne's coldest mornings. While efficiency may diminish in extreme cold compared to gas systems, for the majority of Melbourne homes, the difference is minimal. Proper sizing of the unit according to your home’s heating requirements is more crucial than merely the choice of system.

Will Transitioning to Reverse Cycle Lead to Actual Savings?

Most households in Melbourne can anticipate annual savings of between $400 and $800 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 utilising separate heating and cooling systems, as one ducted reverse cycle unit can replace both, eliminating the expenses 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 necessary 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 required switchboard upgrades. Beyond coordinates both trades as part of a comprehensive installation, ensuring you won’t have to manage 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 complete installation generally takes one to two days. If the existing ductwork needs replacement or reconfiguration, or if the switchboard requires upgrading, anticipate a timeframe of two to three days. We provide a detailed timeline as part of the quote to assist in your planning.
