How many rooms?
Multi-Split Aircon South Africa run two to five indoor units from a single outdoor unit, so a whole house can be cooled with one machine outside instead of a row of them. It costs more than one split and less than several, and it is usually chosen for the look as much as the money.

Get the Best QuoteWhy Choose a Multi-Split
- One outdoor unit. A single machine instead of three or four on a wall.
- Complex rules. Where only one outdoor position is permitted.
- Limited outdoor space. A small courtyard or a narrow service passage.
- Tidier. One set of pipes to one place rather than several runs.
- Mixed indoor types. Wall, cassette and ducted units on the same system.
- Independent control. Each indoor unit has its own setpoint and timer.
What It Costs You in Return
- Higher capital cost. More than a single split, per room.
- Single point of failure. One outdoor unit down means every room is down.
- Longer pipe runs. Each indoor unit has its own run to the one outdoor unit.
- Brand lock-in. Indoor units must match the outdoor unit's system.
- Capacity sharing. Running every unit at once does not give every room full output.
- Specialist servicing. More involved than a set of standalone splits.
Designing the System
- Count the rooms. And decide which will actually run at the same time.
- Size the outdoor unit. To the realistic simultaneous load, not the sum of all.
- Choose the indoor types. Wall units in bedrooms, perhaps a cassette elsewhere.
- Plan the pipe routes. Ceiling voids, chases or boxing, agreed before work starts.
- Leave room to add. A spare port now is far cheaper than a new system later.
- Position the outdoor unit. Accessible, ventilated and not under a bedroom window.

Get the Best QuoteWhat Affects the Price
- Number of indoor units. Both the outdoor plant and the pipework scale with it.
- Total capacity. Sized to the simultaneous load across the rooms.
- Indoor unit types. Cassettes and ducted units cost more than wall units.
- Pipe run lengths. Each indoor unit has its own run, and they add up.
- Routing difficulty. Ceiling voids are cheap; chasing finished walls is not.
- Brand tier. The spread at the same configuration is wide.
What to Include in Your Request
- How many rooms. And roughly how big each is.
- Which run together. Realistically, at the same time.
- Where the outdoor unit can go. And whether that is dictated to you.
- Single or double storey. And which rooms are upstairs.
- What the ceilings are. Whether there are voids for pipe routes.
- Whether you may expand. Rooms you might add in a year or two.
Before the Installer Quotes
- Ask for both options. A multi-split and separate splits, priced side by side.
- Ask about simultaneous capacity. What every room gets when all are running.
- Ask about a spare port. Adding one later is far cheaper than a new system.
- Understand the single failure point. One outdoor unit serves every room.
- Agree the pipe routes. Before anyone starts chasing a wall.
- Check parts availability. Indoor units must match the system for years to come.
Multi-Split Aircon FAQs
What is a multi-split system?
It is one outdoor unit serving several indoor units, typically two to five, each controlled independently in its own room. It sits between a set of separate splits and a full VRF system: more expensive than individual splits per room, far cheaper than VRF, and it leaves you with one machine outside instead of several.
Is a multi-split cheaper than separate splits?
Usually not. The outdoor plant and the pipework cost more than the equivalent individual units, and labour is similar. What a multi-split buys you is one outdoor unit instead of four, which matters when the complex allows only one position, when there is nowhere to put a row of condensers, or when the look of the building matters.
What happens if the outdoor unit fails?
Every indoor unit on that system stops. It is the main trade-off against separate splits, where a failure takes out one room. If continuous cooling in a particular room is important, that is an argument for keeping that room on its own dedicated unit.
Can I run all the rooms at full output at once?
Usually not quite. The outdoor unit is sized to a realistic simultaneous load rather than to the sum of every indoor unit at maximum, so when everything runs flat out on the hottest afternoon, each room gets a little less. A good installer sizes for how the house is actually used and tells you where the limit sits.
Can I add a room later?
Only if the outdoor unit has a spare port and enough capacity in reserve. If there is any chance of adding a room, specify that at the start: a spare port on the original system costs very little, and discovering there isn't one means a second outdoor unit, which is the thing you chose a multi-split to avoid.
Multi-split systems are one of the types providers listed on Aircon Hub quote for, alongside single splits, ducted and cassette units.
