If you want to heat or cool multiple rooms in your home without a small army of outdoor units cluttering your garden, a multi-split heat pump system is the perfect solution. One powerful outdoor compressor connects to up to six indoor units of your choice — hi-wall, floor consoles or ducted — giving you independent temperature control in every room.
Why this works
Tidy Exterior
One neat outdoor unit instead of three or four. Your garden and exterior stay uncluttered.
Room-by-Room Control
Each indoor unit has its own set temperature and remote. No more arguments over the thermostat.
Energy Smart
Only run the rooms you're actually using. Inverter compressor ramps up and down to match demand.
Future-Proof
Buy a 4-room outdoor unit now, hook up two indoor units today, add more later without major work.
Mix & Match Indoor Styles
Combine hi-wall, floor console and ceiling cassette units to suit each room.
No Roof Space Needed
Great for homes without enough roof cavity for a full ducted system.
The Specs That Matter (In Plain English)
Multi-split specifications look a bit different from standard single-split systems because they balance multiple indoor units at once. Here's what you need to know:
Key Features To Look For
The Golden Rule — One Mode at a Time
Everyone can choose their own temperature, but a multi-split system must be entirely in Heating mode or entirely in Cooling mode at the same time. You can't heat the lounge while cooling a bedroom on the same outdoor unit.
Mix & Match Indoor Styles
Hi-Wall — space-saving comfort in bedrooms and lounges. Floor Consoles — rapid heating, sitting low where cold air pools. Compact Cassettes — flush into the ceiling for a sleek, hidden look.
A multi-split is right for you if you want individual climate control in 2–6 rooms, only one neat outdoor unit on display, or don't have enough roof cavity for a full ducted system. Get in touch for a free site assessment.

No — all rooms on the same outdoor unit must run in the same mode at the same time. You can set different temperatures, but not different modes. For mixed mode you'd need separate single-split systems.
Typically 2 to 6 indoor units per outdoor unit, depending on the model.
Yes — that's one of the main advantages. You can also include compact ceiling cassettes.
The outdoor unit costs more, but you only have one to service and one to install. Long-term it's usually more cost-effective and far tidier.
