Split system installation is the standard for Australian homes: unit plus install typically lands between $1,200 and $4,500 depending on size and pipe run.

The national ranges below are the honest baseline for Perth: no published Perth-specific figures met our sourcing bar, so local quotes land inside these bands, with WA labour rates and disposal fees the main local variables. This edition therefore points at the national Air Conditioning Installation report as the canonical version until a sourced Perth figure lands.

Common questions#
What size split system do I need?
Roughly 1kW of cooling per 10 square metres of well-insulated space: a 2.5kW unit suits a bedroom, 5kW a living area, 7 to 9kW for open plan spaces.
What is a back-to-back installation?
The indoor and outdoor units sit on opposite sides of the same wall with a short pipe run. It is the cheapest install; every extra metre of piping adds cost.
