Advice
Straight answers from the team that does the installs. What systems cost, how they are sized, what the fault codes mean and what changes the price on a real job.
A split system should be installed on a wall where the airflow does not blow directly onto the bed, ideally to the side of the sleeping area or above the headboard. It requires at least 150mm of clearance from the ceiling for air intake and should be positioned on an external wall to simplify condensate drainage and pipework.

A standard back-to-back split system installation in Australia typically costs between $600 and $1,100 for labour and basic materials, excluding the unit itself. For a complete supply and install package, expect to pay between $1,400 for a 2.5kW bedroom unit and up to $3,800 for a large 8kW living area system, depending on brand and electrical complexity.
