Ducted Gas and Reverse Cycle: Melbourne Homeowners’ 2026 Choices

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 heating against reverse cycle heating for your Melbourne home in 2026? Let’s delve into these options in detail, free from any sales pressure, allowing you to make an informed decision.

Comprehend Melbourne's Heating Regulations and Anticipated Changes for 2026

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

Here’s what this regulation means for homeowners:

• If your home currently uses gas: You are not required to make immediate changes. You may continue using your existing ducted gas system, replace it with another gas unit upon its expiration, or switch to reverse cycle heating at your convenience.
• If you are building a new home: You must implement an all-electric system. Reverse cycle heating and cooling has become the standard for all new constructions.
• If you are carrying out significant renovations requiring new gas lines: It is essential to consult your builder, as some councils are beginning to impose restrictions on new gas installations, even within existing homes.

Evaluate the Benefits of Ducted Gas Heating for Homes in Melbourne

Ducted gas heating continues to be a practical solution for many households in Melbourne. Its benefits include:

• Rapid heating: Gas burners quickly reach their operational temperature. In contrast, reverse cycle systems may take longer to warm up, particularly during cold mornings when your home has been chilly overnight.
• Reliable heat distribution: Efficiently designed ductwork ensures that heat is distributed uniformly throughout your home, ensuring comfort in every room.
• Efficiency 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 have a distinct advantage.
• Utilisation of existing infrastructure: If your ductwork, controls, and gas lines are well-maintained, replacing your gas unit with another ducted gas heater is typically a cost-effective option that can often be completed within a single day, unlike switching to a reverse cycle system.

Compare the Advantages of Reverse Cycle Systems Versus Ducted Gas

• Combined heating and cooling: A reverse cycle system provides warmth in winter and cooling in summer, eliminating the need for a separate cooling solution that ducted gas does not encompass.
• Reduced operational expenses: Contemporary reverse cycle systems boast high efficiency, producing three to five units of heat for every unit of electricity consumed—an efficiency level gas systems struggle to match.
• No combustion emissions: Reverse cycle systems eliminate the risks associated with gas combustion, including the requirement for flues and concerns regarding carbon monoxide safety.
• Improved zoning capabilities: Many modern reverse cycle systems allow for specific rooms to be heated or cooled independently, preventing unnecessary heating in unoccupied areas.
• Future-proof investment: With gas prices in Victoria consistently rising over the past five years, reverse cycle systems offer a safeguard against increasing energy costs.

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

Here 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, influenced by usage patterns, energy tariffs, and the efficiency of the unit.
• Annual running cost for ducted reverse cycle: This usually 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 switching, not accounting for 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, irrespective of the chosen heating system. Addressing draughts, insulating ceilings, and implementing 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 is operating efficiently: You can replace it with a similar unit when it ultimately fails, thereby retaining 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, potentially increasing 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 face difficulties. It’s wise to assess your specific home instead of relying solely on general information.
• If heating is your only requirement without the need for cooling: A new ducted gas unit generally has a lower initial cost compared to a ducted reverse cycle system. If cooling is unnecessary, gas might remain the more economical choice.

Recognise When Reverse Cycle Systems Are the Preferred 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 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 phase allows for a well-designed system rather than a temporary solution.
• If your goal is to lower energy expenses: Reverse cycle systems consistently provide better performance than ducted gas in terms of running costs in Melbourne, with the gap widening over time.
• If future resale value is a consideration: Prospective buyers increasingly favour energy efficiency and cooling options, areas where reverse cycle systems excel.

Seek Professional Guidance to Determine Your Home’s Optimal Heating Solution

For the majority of Melbourne homes in 2026, reverse cycle ducted systems present a more advantageous long-term solution.

Clarify Common Questions About Heating Solutions in Melbourne

Is Gas Heating Being Phased Out in Victoria?

No, existing homes are not affected. 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 pertains to 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 carried out by a licensed gas fitter in accordance with AS/NZS 5601 gas installation standards, and 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 manage the load, expect an additional cost of strong,500 to ,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 effectively at temperatures as low as minus five degrees Celsius, which is sufficient for Melbourne's coldest mornings. While efficiency may diminish in extreme cold compared to gas, for most Melbourne homes, the difference is negligible. Properly sizing the unit based on your home’s heating requirements is more crucial than the mere choice of system.

Will Transitioning to Reverse Cycle Result in Real Savings?

Most households in Melbourne can anticipate saving between $400 and $800 annually on running costs when switching from ducted gas to ducted reverse cycle, assuming comparable 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 costs linked 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 need 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 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.
