Sydney installation cost FAQs
How much does it cost to install a split system in Sydney?
A small bedroom split costs $1,350–$2,000 installed in Sydney; a large living-area split runs $2,100–$3,500. The spread comes from unit brand and install complexity, back-to-back installs sit at the bottom of the range, long pipe runs and double-storey work at the top.
What does ducted air conditioning cost in Sydney?
$6,500–$12,000 installed for most Sydney homes, single-storey zoned systems from around $6,500, larger two-storey zoned systems toward $12,000. Roof cavity access is the big variable; tight or complex cavities add labour.
Why do quotes vary so much between Sydney suburbs?
Housing stock and access. Brick veneer on a full block in the west quotes less than a terrace in the inner west (no roof cavity, tight courtyards) or a strata apartment in the east (approvals, cranage, marine-grade units). Our suburb pages break down exactly what moves the price where you live.
When is the cheapest time to install aircon in Sydney?
Autumn and early spring. Installers discount to fill shoulder-season calendars; by December they’re booking weeks out and January carries a genuine demand premium, typically 15–20% over the same job quoted in May.
How long does installation take in Sydney?
Once quoted, most split installs are a half-day job scheduled within 1–2 weeks. Ducted installs run 1–2 days on site. In peak summer, add 2–4 weeks of queue before the crew arrives, another reason to book in the shoulder season.

Western Sydney
Installs quote under the metro average, but summers run 4–6°C hotter than the coast. Save on the labour, spend it on a bigger unit.
Eastern Suburbs
Apartment territory: strata approval first, marine-grade units for the salt air. Expect around 10% above the metro average.
Inner west
Terraces rarely fit ducted, there’s no roof cavity. Well-placed splits room by room are the local answer.
Hills District
Big two-storey homes built for zoned ducted. Compare quotes on zone count, not just kilowatts.
