Autumn and winter, but in Kal the bigger lever is booking ahead, mining keeps trades busy in every season.

Goldfields heat and dust
Kalgoorlie summers run hot, dry and dusty for months. Units work hard here, and dusty coils need cleaning more often than the coast.
Evap country converting
Evaporative cooling suits the dry heat and is everywhere in Kal, but refrigerated splits that also heat the frosty winter nights are the growing conversion.
Freight and a small pool
Everything arrives with freight and the installer pool is small, prices sit above Perth and lead times run longer. Plan ahead.
Mining-town calendars
Trades run busy year-round in Kalgoorlie. Booking early matters more than season here.
