Why choose a split system?
Split system air conditioners are a great choice for those wanting comfort that blends unobtrusively with its surroundings. The benefits include:
Efficiency
Energy-efficient heating and cooling — modern inverter units sip power compared with older systems.
Wall or Floor Mount
Split systems can be wall mounted or floor mounted to suit any room layout or aesthetic.
Size Range
Available in a wide range of sizes and shapes — from a 2kW bedroom unit up to large living-area systems.
Smooth & Quiet
Modern split systems run remarkably quietly — barely noticeable in bedrooms, even at full output.
Save Money
Cheaper installation and faster install time than a ducted system — generally a 1-day job for a single unit.
Low Maintenance
Minimal maintenance required — clean filters every 3 months and an annual service is all you need.
Our 5-step install process.
A split system has two components — an indoor unit and an outdoor unit. Here's exactly how we get it installed and running:
Mount Bracket
Install the indoor mounting bracket in the desired location.
Create Hole
Cut the wall penetration for pipework, electrical and drainage.
Run Connections
Feed pipe and wiring through the wall to the outside.
Mount Indoor
Hang the indoor unit and connect pipe + wiring to the back.
Outdoor & Commission
Position the condenser, secure on brackets, connect, commission.

What is the best split system air conditioner?
As with any aircon unit, check air conditioner reviews, star ratings, noise levels and running costs. The best split system air conditioner will be entirely dependent on what you actually need installed. For specific advice on your room and budget, speak with a Mr Splits professional — we'll size the system properly and recommend a brand to suit.
How does a split system air conditioner work?
Reverse cycle simply means the heating or cooling process can be reversed. Split system reverse-cycle air conditioners draw warm air in from outside via the condenser to warm your home, or draw warm air out from inside and dissipate it outside to cool your home.
What is the smallest size split system air conditioner?
The smallest split we generally install is a 2kW system — typically suitable for a small bedroom no more than 15m².
How is a split system air conditioner installed?
A split system is made up of two separate components — one indoor unit and one outdoor unit. Step 1: Mount bracket. Step 2: Create penetration. Step 3: Run pipes & wires. Step 4: Secure indoor unit. Step 5: Position outdoor unit, connect and commission.
How much does it cost to install a split system aircon unit?
Installation prices vary with the size of the unit, the brand chosen, and the install location. Prices for a small bedroom can start from $1,290 and a larger space from $2,290.
How much does it cost to replace a split system aircon unit?
Replacement prices follow the same range as installation — from $1,290 for a small bedroom up to $2,290+ for larger spaces. If you choose to have your system serviced before deciding to replace, and we then advise replacement, we'll reimburse $99 of your service fee.
