Choose from ducted reverse cycle systems, multi split units, and take advantage of generous government rebates.
Reverse cycle systems function as both heaters and coolers, using refrigerant technology:
This all-in-one solution is perfect for year-round comfort and contributes to reducing your household’s carbon footprint.
Enjoy whole-home comfort with Zero Energy’s ducted reverse cycle systems—designed to deliver powerful, energy-efficient heating and cooling through a single, discreet solution. Perfect for medium to large homes, ducted systems use a central indoor unit connected to ceiling or floor vents throughout the house, offering uniform temperature control across every room.
Zero Energy supplies and installs trusted brands like Mitsubishi Electric, Daikin, ActronAir, and Midea VRF.
Whether you’re replacing an old gas heater or building an energy-efficient new home, ducted aircons and ducted heaters offers reliable comfort, year-round performance, and a cleaner future for your family.
AirTouch is a smart controller for ducted and multi-split air conditioning systems, offering advanced control, comfort, and energy efficiency. It connects via an app or wall panel, allowing homeowners to manage temperature and airflow by zone.

Multi Split Air Conditioning Systems are a smart, space-saving way to heat and cool individual rooms in your home—perfect for small to medium-sized properties or households that want flexibility and control. These systems connect multiple indoor units to a single outdoor unit, allowing you to customise temperatures room by room, without installing a full ducted network.
Zero Energy offers a range of high-quality multi split systems from top-tier brands like Mitsubishi Electric, Daikin, Panasonic, and Carrier. We also help eligible customers unlock rebates through the Victorian Energy Upgrades (VEU) program, reducing your upfront costs.
Victorians can save big on energy-efficient heating and cooling systems thanks to government rebates under the Victorian Energy Upgrades (VEU) program.
We’ll handle the rebate paperwork for you—making it easier to upgrade your comfort and energy efficiency.
A ducted system uses a central unit connected to ducts that distribute heated or cooled air through vents in multiple rooms. It’s ideal for whole-home climate control with a clean, unobtrusive look.

Yes, you can. However, it usually comes at an additional cost due to compliance requirements. Every home is different, so please contact us for an exact installation quote.
Yes, you can. An AC-coupled battery is a great option for retrofitting a battery to your existing solar system.
Yes, blackout backup protection is available as an optional feature at an additional cost.
Yes, we can help arrange that. Please get in touch with our team to explore compatibility with your specific brands and devices.
Rooftop solar is one of the most effective ways to cut household carbon emissions.
A 6.6 kW system (roughly 18–20 panels) can generate around 8,000–9,000 kWh annually in Melbourne, supplying most of a home’s electricity and significantly reducing reliance on fossil-fuel-powered grid energy. This clean energy output can offset nearly 100% of a typical home’s usage, with excess fed back into the grid. Solar is a key part of Victoria’s net-zero goals, typically eliminating 5–8 tonnes of CO₂ per year.
It’s an essential step in transitioning to renewable energy and achieving meaningful environmental impact at the household level.
Installing a home battery (e.g. 10 kWh) maximises the benefits of rooftop solar by storing excess energy for use at night.
While it doesn’t generate power, it boosts solar self-consumption—raising it from ~20–40% to 60–80% of total generation. This reduces reliance on fossil-fuelled grid electricity during peak times. A 10 kWh battery charged daily can store around 3.65 MWh annually, offsetting energy that would otherwise come from gas or coal plants.
By shifting usage to clean, stored energy, batteries enhance energy independence and contribute to significant carbon emissions reductions, particularly in states like Victoria with fossil-heavy grids.
Switching from gas-fired HVAC to an all-electric ducted heat pump system significantly cuts fossil fuel use. Modern reverse-cycle systems offer both heating and cooling efficiently.
In Victoria, the average household uses around 50 GJ of gas annually for heating, generating about 2.5 tonnes of CO₂. Replacing this with a 16 kW heat pump powered by renewable electricity can eliminate those emissions. Government rebates support this transition, helping homeowners save up to $500 per year on heating costs.
Electrifying home heating is essential for achieving zero-carbon homes and reducing environmental impact while improving energy efficiency and year-round comfort.
Water heating is a major household energy use, often powered by gas or outdated electric systems. Replacing these with electric heat pump hot water units can reduce energy consumption by 60–75%.
For example, a heat pump may use only ~1,000 kWh annually versus ~3,000–4,000 kWh for old electric tanks, saving ~2,000–3,000 kWh and 1.7–2.6 tonnes of CO₂ per year. Replacing a gas unit also cuts ~0.8–1.0 tonnes of emissions. When powered by renewables, heat pumps can reduce emissions to near zero.
Experts call this one of the most cost-effective upgrades in a home’s transition to all-electric living.
Transportation is a major contributor to carbon emissions. Switching from a petrol or diesel car to an electric vehicle (EV), especially when charged with rooftop solar, can drastically reduce emissions.
Petrol cars emit ~180–200 g CO₂ per km, while EVs charged from solar have near-zero operational emissions. Even on Victoria’s grid, EVs emit ~100–150 g/km—still significantly lower. With solar, every kilometre driven saves ~0.18 kg CO₂, achieving a 97% emissions reduction.
Pairing an EV with solar energy not only slashes running costs but also makes personal transport cleaner, helping households dramatically reduce their environmental impact while gaining long-term savings.
