What moves a Busselton split quote
Back-to-back, or not
The cheap baseline: indoor unit on an external wall, condenser directly behind it. Every metre the two units drift apart adds piping, cabling and labour, the biggest single swing on most quotes.
Electrical work
Bigger units need a dedicated circuit, and older switchboards sometimes need an upgrade to take one. Legitimate money, but it should be an itemised line, not a surprise on install day.
The growth city of the south-west
New estates around Busselton and Vasse are clean split and ducted territory, and the building boom keeps installers competitive.
Milder than Perth
The south-west runs gentler summers. Honest sizing beats oversizing, and reverse-cycle heating earns its keep in the cool winters.
