Which One Is Right for Your Melbourne Home?
Thinking about installing air conditioning in multiple rooms? A multi-split system is one of the smartest ways to heat and cool your Melbourne home efficiently.
Two popular choices under the Victorian Energy Upgrades (VEU) program are Midea and Rinnai — both trusted brands offering energy-efficient systems with generous rebate eligibility.
At UpgradeX, we help Victorian homeowners compare features, maximise rebates, and install the right system the first time.
A multi-split air conditioner connects multiple indoor units (up to 6) to a single outdoor unit.
Why Melbourne Homes Love Multi-Split Systems:
- Individual temperature control in each room
- Less outdoor clutter
- Ideal for townhouses and compact properties
- Perfect replacement for outdated gas heaters
- Energy-efficient heating & cooling across zones
