Expert Installation
Multi split installation across Sydney. One outdoor unit, several rooms cooled, correctly sized heads and strata friendly placement, installed and commissioned properly.
One Unit, Several Rooms
A multi split installation is a design job before it is an install job. One outdoor condenser runs pipework to several indoor heads, and every decision about where those heads sit, which rooms they serve and how big each one is gets made before a single hole is cut. Get that right and each room is comfortable on its own schedule. Get it wrong and you spend years explaining why the spare room never quite cools.
Head by head
We install two, three, four and five head systems across Sydney homes, apartments and townhouses. The condenser sits in the only outdoor position you have and each head runs from it, which is why multi splits suit properties where three separate condensers would never fit or would never be approved. If you are still deciding between systems, start with the full range of air conditioning in Sydney we supply and install.
01
| Room | Head type we would use | Why |
|---|---|---|
| Bedroom | Wall mounted, high on a wall opposite the bed | Avoids blowing directly onto anyone sleeping |
| Living area | Wall mounted or bulkhead | Longer throw for a larger volume of air |
| Kitchen or open plan | Bulkhead cassette or a larger wall unit | Handles the extra load from cooking and glazing |
| Study or small room | The smallest wall unit in the range | Oversizing a small room is uncomfortable and wasteful |
| Extension or granny flat | Wall mounted on its own zone | Can be run independently of the main house |

The condenser is deliberately smaller than the combined capacity of every head, because households rarely run everything at full power at once. That assumption is called diversity. If you genuinely will run every head together on a 40 degree day, say so at quoting stage and the system gets specified for it. This is where multi split systems go wrong when they are specified from a catalogue instead of a calculation.
Each head is sized for its own room, using ceiling height, glazing, orientation and insulation. A west facing bedroom with full afternoon sun needs more capacity than a shaded one of the same size, which is precisely why adding up floor area does not work.

A two head system is usually a full day. Each additional head adds pipework, a wall penetration, a drain and its own commissioning, so four and five head systems often run into a second day. Double brick, long runs and roof access all add time. We confirm the timeframe in your quote rather than estimating over the phone. If you only need one room done, compare split system installations instead.
05
Most strata buildings need written approval before anything is mounted on common property or visible from outside. A single condenser is usually a far easier conversation than three, which is a genuine advantage of the multi split. We supply specifications and compliance details for your strata committee or building manager, and we work around tenants where the property is tenanted. If your building cannot take a condenser at all, a ducted system or another system type may be the answer.
After the install
Every head has its own filter, coil and drain, so servicing is per head, not per system. Book multi split maintenance once a year and tell us how many heads there are so enough time is booked. If a head stops working, start with multi split repairs.
What Sydney homeowners ask before installing a multi split system.
Cost depends on how many heads you need, the capacity of each one, how far the rooms sit from the condenser and whether electrical work is required. A two head system sits at the low end, and every additional head adds unit cost plus installation time. We assess on site and give you a written figure covering supply, labour and materials before anything is ordered.
