What moves a Mount Gambier 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.
Heating-first, like Hobart
The Limestone Coast runs cool and damp most of the year. Reverse-cycle here is a heating decision, compare the low-temperature output numbers.
SA power prices
Mount Gambier pays South Australia's high tariffs, the efficiency gap between two units is worth more here than the price gap between them.
