Victoria’s winters bring chilly mornings, cool evenings, and a growing need for reliable home heating. For many homeowners, the biggest question is whether to stick with ducted gas heating or upgrade to a reverse-cycle split system.
With gas prices continuing to rise and the Victorian Government encouraging households to transition to energy-efficient electric solutions, many homeowners are now making the switch. As a VEU Accredited Provider, Aussie Energreen helps eligible Victorians upgrade to modern heating and cooling systems while accessing available government rebates.
In this guide, we compare ducted gas heating and split systems to help you choose the best solution for your home.
Understanding Ducted Gas Heating
Ducted gas heating has been a popular option for Victorian homes for many years. These systems use a central gas furnace to heat air and distribute it through ductwork, providing warmth throughout the home.
Advantages
- Quick and even heating
- Ideal for larger homes
- Centralised temperature control
Limitations
- Relies on natural gas, which continues to increase in price
- Older systems may operate at lower efficiency levels
- Heats the entire home, including unused rooms
- Requires regular servicing and safety inspections
While ducted gas systems remain effective, many ageing units are becoming expensive to run compared to modern electric alternatives.
What Is a Reverse-Cycle Split System?
A reverse-cycle split system provides both heating and cooling from a single unit. Instead of generating heat by burning gas, it transfers heat using advanced heat pump technology, making it significantly more energy efficient.
Single split systems are ideal for individual rooms, while multi-head systems can comfortably heat and cool multiple areas without requiring ductwork.
Benefits
- Heating and cooling in one solution
- High energy efficiency
- Lower running costs
- Quiet operation
- Compatible with rooftop solar systems
Because they only condition occupied spaces, split systems can help reduce unnecessary energy usage.
Energy Efficiency Comparison Split System vs Ducted Gas Heating
| Feature | Ducted Gas Heating | Reverse-Cycle Split System |
|---|---|---|
| Energy Source | Natural Gas | Electricity |
| Heating & Cooling | Heating Only | Heating & Cooling |
| Operating Efficiency | Moderate | Very High |
| Room Control | Whole House | Individual Zones |
| Solar Compatibility | No | Yes |
| Running Costs | Higher | Lower |
| Environmental Impact | Higher Emissions | Lower Emissions |
For most Victorian households, reverse-cycle split systems offer greater energy efficiency and lower long-term operating costs.
Installation and Running Costs
Upfront Investment
Installing a brand-new ducted gas system can involve significant costs, particularly if ductwork needs to be added or upgraded.
Split systems generally require a lower upfront investment, while multi-head installations remain competitive—especially when government rebates are applied.
Ongoing Energy Costs
Natural gas prices have steadily increased across Victoria, making gas heating more expensive to operate.
Electric reverse-cycle systems use significantly less energy and can deliver further savings when combined with rooftop solar.
Maintenance Requirements
Gas ducted systems require routine servicing to maintain efficiency and ensure safe operation.
Split systems require basic filter cleaning and periodic servicing, resulting in lower ongoing maintenance costs.
Victorian Energy Upgrades (VEU) Rebates
One of the biggest advantages of upgrading to an energy-efficient split system is access to rebates through the Victorian Energy Upgrades (VEU) Program.
Eligible homeowners replacing older gas heating systems may receive substantial upfront discounts on installation costs, making the transition more affordable.
As a VEU Accredited Provider, Aussie Energreen manages the rebate process and helps eligible customers maximise their savings.
Rebate values may vary depending on system specifications and current program requirements.
Is Ducted Gas Still Worth Considering?
For homes with relatively new gas systems that operate efficiently, keeping the existing unit may still make financial sense in the short term.
However, for homeowners replacing ageing equipment, upgrading to a reverse-cycle split or multi-head system typically provides:
- Better energy efficiency
- Lower operating costs
- Heating and cooling from one system
- Reduced environmental impact
- Access to government rebates
Which Option Is Best for Victorian Homes?
When comparing lifetime value rather than just installation costs, reverse-cycle split systems often come out ahead.
They provide year-round comfort, lower electricity bills, and greater flexibility by allowing homeowners to heat or cool only the rooms they use.
Combined with Victorian Government incentives and the growing shift toward electrification, they represent a smart long-term investment for many households.
