Ducted air conditioning
cost in Wollongong

$10,000–$15,800 installed for most Wollongong homes. Single-storey zoned systems run $10,000–$12,900; larger two-storey homes run $12,900–$15,800. Roof cavity access and zone count set where you land, the unit itself is typically only 40–50% of the price.

It depends on the roof. Newer builds and homes with generous cavities install cleanly; older double-brick homes with tight roofs need more planning, and sometimes multiple splits deliver the same comfort for less. A proper site inspection settles it, which is exactly what the quote process is for.

Usually, and by a lot: a like-for-like changeover reusing sound ductwork runs about $10,000–$12,900 in Wollongong, skipping most of the labour. Get the ducts inspected first, old leaky runs can eat the saving in running costs and are sometimes worth replacing anyway.

For 1–3 rooms, splits win on install and running cost. From 4+ daily-use rooms, ducted becomes competitive per room and wins on whole-home coverage and aesthetics. Our split vs ducted calculator runs both totals for your home in thirty seconds, free, no email.

1–2 days on site for a straightforward single-storey install, 2–3 days for two-storey or complex zoning, after a proper site visit and quote, ducted is never priced accurately over the phone. In peak summer, add 2–4 weeks of queue before the crew arrives.
