Emerald Reverse-cycle air conditioning for Melbourne homes.

Ducted Ultra uses VRF (Variable Refrigerant Flow) technology with auto-adjust static pressure — it's the more advanced range, ideal for larger homes and multi-zone setups. Ducted Pro uses a DC Dual-Rotor compressor optimised for consistent performance across a wide voltage range (170–270 V) with Golden Fin anti-corrosion coating. Choose Ultra for scalability and premium efficiency; choose Pro for high-performance reliability at a lower cost.

For most 3-bedroom Melbourne homes, the Emerald Ducted Ultra 16kW or Ducted Pro 16kW is well-sized. 16kW comfortably handles a standard 3–4 bedroom layout with zoning. Renviro Power sizes every system on-site — factors like ceiling height, insulation, and window orientation affect the ideal capacity.

For 4-bedroom homes or larger open-plan designs, the Emerald Ducted Ultra 20kW is our go-to. It's engineered for larger residential and small commercial applications, with high static pressure for extensive ductwork and VRF technology for scalable multi-zone control.

The Multi-Head Pro 12.6kW is designed for residential and small commercial use, supporting 1–5 indoor units with a DC Dual-Rotor compressor. The Multi-Head Ultra 18.1kW is a higher-capacity system with VRF technology, suited to larger residential and commercial applications. Choose Pro for standard multi-room homes; Ultra for larger or multi-storey spaces needing more output.

Choose ducted when you want centralised whole-home cooling with consistent airflow, a cleaner aesthetic (only vents visible in ceilings), and existing or feasible ductwork. Ducted is typically preferred for new builds, renovations, and larger homes.

Choose multi-head when you want to cool or heat only specific rooms (rather than the whole house), when ductwork installation isn't practical (older homes, high ceilings, tight roof spaces), or when you want independent temperature control per room. Multi-head is also typically more affordable to install than full ducted.

Golden Fin is Emerald's anti-corrosion coating applied to the outdoor coils. It significantly improves resistance to salt air, humidity, and pollutants — extending the life of the outdoor unit. Emerald Ducted Ultra 20kW uses Golden Fin 2× for even greater durability. This makes Emerald systems especially well-suited to Australian coastal and outer-suburb installations.

Yes. Switching from gas ducted heating to Emerald reverse-cycle ducted is one of the most rewarding rebate scenarios in Victoria. VEU rebates for this switch typically range from $2,450 to $5,180 depending on system size and setup. Emerald reverse-cycle systems provide both heating and cooling from one unit, so you're future-proofing against rising gas prices.

Emerald ducted systems support multi-zone configurations, letting you cool or heat specific areas of your home independently. Typical Melbourne installations use 3–6 zones based on floor plan and household routine. Renviro Power designs the zoning during the free on-site quote to match how you actually use your home.

The Emerald Multi-Head Pro 12.6kW and Multi-Head Ultra 18.1kW support up to 5 indoor units connected to a single outdoor unit — meaning you can cool up to 5 rooms independently. Each indoor unit has its own remote and can be controlled via the Emerald App.

DC Dual-Rotor is Emerald's compressor technology that delivers stable, high-efficiency operation across a wide voltage range (170–270 V on Pro models). It reduces power consumption, handles Australia's grid voltage fluctuations reliably, and produces less vibration and noise than traditional single-rotor compressors.

Yes — Emerald multi-head systems are ideal for older Melbourne homes without ductwork. Because they only require refrigerant line penetrations (not full duct runs), they can be installed in period homes, terraces, and heritage properties without major structural work. Renviro Power specialises in these tricky installs.

Yes. Emerald reverse-cycle systems qualify for the Victorian Energy Upgrades (VEU) program, particularly when replacing gas ducted heating. VEU rebates range from $2,450 to $5,180 depending on system size and your current setup. Renviro Power handles the full rebate application.
