What Size Split System Aircon Do I Need?
Getting the capacity right matters more than simply buying the biggest unit you can afford.
An undersized system may struggle to reach your target temperature, particularly on very hot or cold days. An oversized system can also operate inefficiently and may not manage humidity as effectively.
As a general guide for rooms with standard ceiling heights:
|
Room Size |
Typical Application |
Approx. Capacity |
|
Up to 20m² |
Small bedrooms, studies and home offices |
2.5 kW |
|
20–40m² |
Larger bedrooms and living areas |
3.5–4.5 kW |
|
40–60m² |
Open-plan living and dining areas |
5.0–7.0 kW |
|
60m²+ |
Large open-plan areas |
8.0 kW+ |
These figures are a starting point, not a substitute for assessing the individual room.
What else affects air conditioner sizing?
Your required system capacity can also be influenced by:
- Room orientation and exposure to the sun
- Window size and glazing
- Insulation
- Ceiling height
- Number of occupants
- Open-plan vs enclosed spaces
- Existing heat sources
- The home's construction and layout
Not sure what size split system you need? That's our job to work out.
We'll assess your space and recommend a system suited to the room rather than simply selling you the largest unit available.

One Split System Air Conditioner or Multiple Rooms?
If you're trying to air condition several rooms, you don't necessarily need a separate outdoor unit for every room.
A standard split system has one indoor unit connected to one outdoor unit. It's ideal when you're primarily looking to control the temperature in a single bedroom, living area or other space.
A multi-split system can connect multiple indoor units to a single outdoor unit, making it an option when you want individual rooms to have their own temperature control without installing several outdoor condensers.
Which is right for your home?
A single split system may suit you if:
- You only need one room conditioned
- You want a straightforward installation
- You're adding air conditioning to a bedroom or living area
A multi-split may be worth considering if:
- You want to condition several separate rooms
- Outdoor space for multiple condensers is limited
- You want independent temperature control in different rooms
We can assess your home's layout and explain which approach makes sense before you commit to a system.
💡Coastal Air Insight: If you're planning to install air conditioning in several rooms, tell us before buying individual units. It's worth looking at the whole-home layout first, the cheapest individual installation isn't always the most practical overall solution.
How Much Does Split System Air Conditioning Installation Cost?
The price of an air conditioner installation depends on more than the unit itself.
A straightforward back-to-back installation is generally simpler than an installation requiring long pipe runs, difficult access or additional electrical work.
When we provide your quote, we'll consider the complete installation rather than giving you a vague starting price and adding unexpected extras later.
What can affect your installation cost?
Your final price may depend on:
- The size and model of the air conditioner
- Back-to-back vs extended pipe runs
- Indoor and outdoor unit positioning
- Wall, ground or roof mounting requirements
- Access to the installation area
- Condensate drainage requirements
- Existing electrical infrastructure
- Whether an electrical upgrade is required
- Removal of an existing air conditioner
- The number of storeys or complexity of the property
We'll explain any additional requirements before the work begins, so you know what you're paying for.

What's Included in a Standard Back-to-Back Aircon Installation?
A back-to-back installation is where the indoor unit and outdoor condenser are positioned on opposite sides of the same wall, allowing for a relatively short and direct pipe run.
For a standard installation, our inclusions can include:
- Up to 3 metres of copper pipework
- Neat external trunking where required
- Outdoor mounting pad or suitable wall brackets
- Weatherproof electrical isolator
- Refrigeration pressure testing
- Deep vacuum of the refrigeration system
- Sealing of wall penetrations
- Installation and connection of condensate drainage
- Testing and commissioning of the system
- Removal of installation rubbish and packaging
If your property requires a longer pipe run, roof mounting, additional drainage, difficult access or electrical work, we'll identify this during the assessment and explain it in your quote.
No guessing. No surprise extras on installation day.
What Happens During a Split System Air Conditioner Installation?
Installing a split system properly involves more than putting an indoor unit on the wall and switching it on.
1. We assess your space
We'll look at the room, layout, positioning, access and other factors that can influence the installation.
2. We help you choose the right system
We'll consider the required capacity, heating and cooling requirements, energy efficiency and where the system needs to be installed.
3. We install the indoor and outdoor units
The units are positioned carefully for effective operation, accessibility and a neat finish.
4. We connect the refrigeration and electrical components
Pipework, drainage and electrical connections are installed according to the requirements of the system and property.
5. We pressure test and evacuate the system
The refrigeration circuit is tested and evacuated before commissioning to help ensure the system is properly sealed and ready to operate.
6. We test the finished installation
We'll run the system, check its operation and make sure everything is working correctly before we leave.
A good installation isn't just about making the air conditioner look neat. It's about making sure it operates properly from day one.
Replacing an Existing Split System? Don't Assume You Need the Same Size
If your old air conditioner has finally given up, replacing it with the same kW capacity isn't always the right answer.
Your home's insulation, room layout, windows and usage may have changed since the original system was installed.
We can assess the existing installation and determine whether:
- The current capacity is still appropriate
- The system is in a suitable position
- Existing pipework can be reused
- The electrical supply is adequate
- The drainage arrangement needs changing
- A newer, more efficient system would better suit the room
💡Coastal Air Insight: An old system can tell us a lot about the room, but it shouldn't automatically dictate what replaces it.
Split Systems for Coastal Homes: Protecting Against Salt-Air Corrosion
Living near the coast creates another consideration when choosing an outdoor air conditioning unit.
Salt and moisture in coastal air can contribute to corrosion of exposed metal components, including the outdoor heat exchanger.
Because Coastal Air specialises in installations around Shoalhaven and South Coast, we understand the conditions local systems are exposed to.
We can recommend suitable systems and features designed to provide greater protection against the coastal environment, including models with anti-corrosion treatments such as Blue Fin or Gold Fin coatings where available.
We supply leading brands including Daikin, Mitsubishi, and Fujitsu, with system recommendations based on your home, requirements and budget.
The right air conditioner isn't just about how cold it gets. It's about choosing a system suited to where you live.
Why Use a Refrigeration Technician to Install Your Split System?
Your split system isn't simply an electrical appliance. It's a refrigeration system.
At Coastal Air, our ARC-licensed refrigeration technicians understand the refrigeration cycle, refrigerant handling, pipework, flaring, pressure testing, evacuation and condensate drainage involved in a professional installation.
That attention to the refrigeration side of the installation helps your new system operate efficiently and reduces the risk of problems caused by poor installation practices.
It also means you have one experienced team looking after the installation from the refrigeration system through to commissioning.
Install it properly once. Enjoy the comfort for years to come.

Questions About Split System Air Conditioning Installation
▪️How long does split system air conditioner installation take?
A straightforward back-to-back installation can often be completed within a few hours. More complex installations can take longer depending on access, pipework, electrical requirements and the position of the indoor and outdoor units.
We'll give you a better indication of the expected installation time once we've assessed your property.
You can also read our info page here.
▪️Can a split system air conditioner be installed on an internal wall?
Potentially, yes. However, internal-wall installations can require additional pipework and drainage considerations compared with a standard back-to-back installation. We'll assess the location and explain what's involved before installation.
▪️Where should the outdoor air conditioner unit be installed?
The outdoor unit needs adequate airflow and a suitable, stable mounting position. We also consider access for future servicing, noise, drainage and exposure to the coastal environment when determining the best location.
▪️Can you replace my existing split system?
Yes. We can remove an existing split system and install a replacement, with the new system selected according to the room and your heating and cooling requirements.
