Multi-Split Air Conditioning Melbourne
Two or more indoor units running from one outdoor unit — independent comfort in several rooms, with less clutter outside.
A multi-split system connects several indoor units — wall-mounted, floor-standing or concealed — to a single outdoor unit. Each room has its own controller, so you only heat or cool the rooms you are using.
It suits homes where ducting isn’t practical, or where you want several rooms covered without a row of outdoor units on the wall.
Is it right for your home?
Best for
- Two to five rooms in a house, apartment or townhouse
- Limited space outside for outdoor units
- Homes without roof space for ducting
- Mixing indoor unit styles in different rooms
Worth considering
- The outdoor unit’s capacity is shared, so careful sizing matters
- If the outdoor unit needs repair, every connected room is affected
- For some layouts, separate split systems or ducted work out better — we compare both

Multi-split questions
Can each room be set to a different temperature?
Yes. Each indoor unit has its own controller and set temperature. In most multi-split systems all units run in the same mode — heating or cooling — at the same time.
How many rooms can one outdoor unit run?
It depends on the outdoor unit model — commonly two to five indoor units. We match the outdoor unit to the rooms you want covered.
Multi-split or ducted?
Ducted hides everything in the ceiling and suits whole-home comfort; multi-split suits homes without roof space or where only some rooms need conditioning. We’ll show you both options with pricing.
Do you service multi-split systems?
Yes — we service and repair all major brands.
