Call 07 3060 9105Split system installation in Brisbane is the most common way to cool a single room or open-plan space, and it is where cutting corners shows up fastest. A split system is only as good as its installation: the wall position, the pipe run, the condensate drainage, and the dedicated electrical circuit behind it all decide how well the unit performs and how long it lasts. Crusader Electrical & Air installs split systems as a licensed electrical contractor (EC Licence 91149) with ARC refrigerant handling licence L187932, so the whole job is done by one team.

What a Quality Split System Installation Includes
Every installation starts with placement. We position the indoor unit where the airflow actually reaches the living space, not just where the wall is convenient, and the outdoor unit where it has clearance to breathe and will not annoy you or your neighbours at night. The pipe run between them is kept short and concealed wherever possible.
On the electrical side, most split systems need their own dedicated circuit from the switchboard. We run the circuit, fit safety switch protection, and confirm the board has capacity, all in the same visit. The job finishes with commissioning, a run test, and a Certificate of Test for the electrical work.
Choosing the Right Size Split System for a Brisbane Room
Capacity is measured in kilowatts, and sizing it to the room matters more than brand. An undersized unit runs flat out on a February afternoon and still falls behind; an oversized one cycles on and off and dehumidifies poorly. As a rough Brisbane guide, small bedrooms suit around 2.5kW, larger bedrooms and offices around 3.5kW, and open-plan living areas 5kW or more, with ceiling height, insulation, and window area all shifting the answer. We confirm the sizing at quote time rather than guessing.
If you are weighing up a single split against ducted, our ducted air conditioning page covers where each makes sense, and a multi-head split system can cool several rooms from one outdoor unit.
Split System Installation Brisbane FAQs
How long does a split system installation take?
A standard back-to-back installation, with the indoor and outdoor units on either side of the same wall, usually takes 3 to 5 hours. Longer pipe runs, two-storey installs, or switchboard work extend that. We confirm the timeframe when we quote.
Does a split system need its own electrical circuit?
Usually, yes. Most units above the smallest sizes draw enough current to need a dedicated circuit with safety switch protection. Because we are electrical contractors, the circuit and any switchboard work are done in the same visit as the installation.
Can you supply the unit, or do I buy my own?
Either works. We can supply and install a unit matched to your room, or install a unit you have purchased, provided it is new and the right capacity for the space. We will tell you honestly if a unit you have bought is the wrong size before it goes on the wall.
Where should the outdoor unit go?
Somewhere with clear airflow, out of the worst afternoon sun, on a stable base or brackets, and positioned so the noise does not sit under a bedroom window, yours or the neighbour's. Placement is part of the site assessment we do before quoting.
