Cost drivers

What moves a Perth ducted quote

Roof cavity access

The single biggest labour variable. Generous, clear cavities install fast; tight, trussed or insulated-panel roofs add days. Identical floor plans quote differently street to street because of it.

Zone count and controls

Each zone adds motorised dampers, wiring and controller capability. Day/night zoning is the value sweet spot; individual-room zoning with smart control is where quotes climb fastest.

The evap conversion

Swapping old evaporative cooling for refrigerated ducted is Perth's signature ducted job. The old ductwork usually can't be reused, quote it as a full new system.

Brick-and-tile keeps quotes sharp

Perth's single-storey brick-and-tile stock with clean roof cavities is the easiest ducted territory in the country, and quotes are often sharper than the east coast.

Perth ducted cost questions

How much does ducted air conditioning cost in Perth?
$9,000–$15,000 installed for most Perth homes. Single-storey zoned systems run $9,000–$12,000; larger two-storey homes run $12,000–$15,000. Roof cavity access and zone count set where you land, the unit itself is typically only 40–50% of the price.
Should I replace evaporative with refrigerated ducted in Perth?
On the humid days and long 40°C runs, refrigerated wins clearly, which is why the conversion is Perth's most common ducted job. Treat it as a new system: new ducts sized for refrigerated airflow, a bigger electrical load, and a proper heat-load calculation. Quote it against keeping the evap honestly serviced so you're comparing real options.
Is ducted cheaper if the house already has ducts?
Usually, and by a lot: a like-for-like changeover reusing sound ductwork runs about $9,000–$12,000 in Perth, 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.
Ducted or multiple splits, which is right for my home?
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.
How long does a ducted install take in Perth?
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.
