Air conditioning in Curtin — what actually matters
Curtin is early Woden Valley — 1960s split-level and single-storey brick homes, most with original wiring that needs a switchboard check before a modern ducted install goes in.
Curtin's housing stock is broadly 1960s, which means clean truss roof cavities, generous eaves for outdoor unit placement, and enough block area on most sites to sit a condenser well away from bedroom windows. That combination makes Curtin one of the more predictable ducted retrofit suburbs — quotes rarely surprise us on site.
A big share of Curtin homes still run their original gas ducted heating from the 1980s or 90s — typically Brivis, Vulcan or Bonaire. As those systems fail we replace them with reverse-cycle ducted, reusing the existing ductwork where a pressure-and-leak test passes. When it doesn't (about a third of jobs) we re-duct with insulated flexible duct rated for the new system's static pressure.
Near Curtin shops we do a steady stream of switchboard upgrades ahead of ducted installs — a lot of the original 1960s boards were built for single-phase 63A supply and don't have the spare capacity for a 14 kW ducted outdoor unit plus induction cooking plus EV charging. We coordinate the electrical upgrade in the same visit.

Case example — Curtin 4-bed brick veneer ducted retrofit
Original 1982 four-bedroom near Curtin shops with a failed 30-year-old Brivis gas ducted system. Existing ductwork passed leak testing after minor resealing, so we reused it and fitted a Mitsubishi Electric 14 kW ducted unit with 4 zones and MyAir 5 controls. Switchboard was upgraded from an old ceramic-fuse board to a modern 100A three-phase unit in the same visit. Owners report holding 21°C set-point through a cold July week at roughly half the running cost of the old gas system. Two-day install.
