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.
