What moves a Brisbane 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.
Size for the humidity
Brisbane heat is humid heat, and undersized units show it first. Size for moisture, not just the thermometer, especially in older, less-sealed homes.
Queenslanders install cleanly
Timber homes on stumps give installers easy access, which keeps Brisbane split quotes at the sharp end. Slab-on-ground brick homes take a little more work.
