Sydney has a huge number of apartments, and cooling them brings particular considerations — where the outdoor unit goes, and strata approval. Here are the options and how to navigate them.
Splits CommonMulti-split for several rooms
Outdoor UnitWhere it can go is key
StrataApproval often needed
Most Sydney apartments use split or multi-split systems, since ducted often isn’t possible. The key considerations are where the outdoor unit can go and strata (body corporate) approval for external units and works.
The Apartment Challenge
Sydney has one of Australia’s highest concentrations of apartment living, and cooling apartments comes with constraints houses don’t have. Ducted air conditioning is often impractical (no roof space of your own, shared structure), so split and multi-split systems dominate. The two defining questions are practical: where can the outdoor unit go, and will strata approve it? Solve those and a Sydney apartment can be comfortably cooled and heated (see the options above).
The Options
For apartments, the realistic options are: a split system (one indoor head plus an outdoor unit) for the main living area or a bedroom; a multi-split (several indoor heads from one outdoor unit) to cover multiple rooms while needing only one outdoor unit — valuable where outdoor space is limited; occasionally ducted, if the building and layout allow; and, as a last resort, a portable where no fixed system can be fitted. For most Sydney apartments, a split or multi-split is the answer.
The Outdoor Unit Question
Every refrigerated system needs an outdoor unit (the condenser), and in an apartment, where it goes is the central challenge. Common locations are a balcony, a wall-mounted bracket, or a building-designated condenser spot, with a sensible pipework route to the indoor head(s). A multi-split helps by needing only one outdoor unit for several rooms. Some apartments have limited or no suitable location, which is the main constraint — so this is the first thing to assess. We evaluate viable spots when quoting.
Strata & Body Corporate
The other defining factor is strata. Because the outdoor unit and external pipework usually involve common property or the building’s exterior, installing apartment air conditioning typically needs owners-corporation (strata) approval, and schemes often have conditions on location, noise and appearance. It’s essential to get approval before installing. The specific rules are set by your building’s by-laws and committee, but we can advise on what’s commonly involved and ensure the install meets typical requirements.
Choosing for a Unit
Choosing for an apartment means balancing your cooling needs, the viable outdoor-unit location, strata requirements and budget. A single split suits cooling the main living area; a multi-split suits covering several rooms with one outdoor unit; sizing still matters (and in humid Sydney, right-sizing aids dehumidification). We help apartment owners choose a system that fits the unit’s constraints and gets through strata. See our sizing and choosing guides.

Frequently Asked Questions
What air conditioning is best for a Sydney apartment?
For most Sydney apartments, a split system (or multi-split for several rooms) is the answer — ducted is often impractical in apartments. A single split cools and heats the main living area or a bedroom; a multi-split runs several indoor heads from one outdoor unit, covering multiple rooms. The main practical questions are where the outdoor unit can be located and whether strata approval is needed for it. We help apartment owners navigate both.
Can I install air conditioning in a Sydney apartment?
Usually yes, but it depends on the building and strata. The big factors are: somewhere to put the outdoor unit (a balcony, wall bracket, or designated spot), a route for the refrigerant pipework, and body-corporate (strata) approval, since the outdoor unit and any external works typically affect common property. Many Sydney apartments have air conditioning, so it’s commonly done — but the strata process and outdoor-unit location need sorting first. We can advise on what’s feasible for your unit.
Do I need strata approval to install air conditioning in my apartment?
Generally yes — installing an outdoor unit or running pipework usually involves common property or the building’s exterior, which falls under the owners corporation (strata), so approval is typically required. Many strata schemes have a process and conditions (where units can go, noise, appearance). It’s important to get approval before installing. We can advise on what’s usually involved, though the specific rules are set by your building’s by-laws and committee.
Where does the outdoor unit go in an apartment?
That’s the key practical question. Options include a balcony, a wall-mounted bracket, a designated condenser location the building provides, or a roof/common area in some buildings — subject to strata rules and a sensible pipework route to the indoor unit(s). Some apartments have limited or no suitable spot, which is the main constraint on apartment air conditioning. We assess the unit and advise on viable outdoor-unit locations as part of quoting.
Is a portable air conditioner a good idea for a Sydney apartment?
Only as a last resort. Portable units need no installation, which appeals where a split can’t be fitted — but they’re generally weak, inefficient and noisy, and many vent through a window, which is awkward and lets heat back in. For genuine comfort in a Sydney summer, a properly installed split or multi-split is far better. Portables suit only situations where a fixed system truly isn’t possible. We can advise on whether a split is feasible first.
