What moves a Cairns 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.
Corrosion country
Salt air plus tropical moisture eats standard equipment. Coastal-rated, corrosion-protected units are the only sensible Cairns quote.
The wet is the test
Cairns humidity is as hard as Australian conditions get. An undersized split runs flat-out through February and still loses, size for the wet.
