Ducted air conditioning
cost in Adelaide

$8,000–$15,500 installed for most Adelaide homes. Single-storey zoned systems run $8,000–$11,800; larger two-storey homes run $11,800–$15,500. Roof cavity access and zone count set where you land, the unit itself is typically only 40–50% of the price.

More than anywhere per hour of the same cooling, Adelaide has some of the highest power prices in the country. That makes zoning and efficiency worth real money: running two zones instead of the whole house, and buying an efficient unit, both show up on every bill for a decade. Compare quotes on the zoned energy label, not the sticker price.

Usually, and by a lot: a like-for-like changeover reusing sound ductwork runs about $8,000–$11,800 in Adelaide, 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.
