System chooser
Which system suits your place?
Evaporative or refrigerated, ducted or split — the right answer depends on your home, how you live and what you want it to cost to run. Start with six questions, then compare the options side by side.

Why the Goldfields is different
Dry heat, cold nights
Kalgoorlie-Boulder's climate shapes the choice: very dry summer afternoons favour evaporative cooling, while chilly winter nights make heating worth planning for.

Questions
Choosing well
Is evaporative or refrigerated cooling better for Kalgoorlie?
Both work here. Evaporative cooling thrives in dry heat — Bureau of Meteorology averages put January afternoon humidity in Kalgoorlie-Boulder at around 24% — and costs less to run, but needs windows ajar and can't heat. Refrigerated reverse cycle keeps the home sealed, holds up on humid days and heats in winter.
Do I need heating as well as cooling in the Goldfields?
Most homes do. Long-term averages put July nights at around 5°C, with frosts a few times most winters. Reverse cycle systems do both jobs; evaporative cooling is often paired with ducted gas heating.
Which is cheapest to run?
For cooling, government energy guidance (ACT Government) says evaporative systems generally cost less to run than refrigerated ones, and split systems cost less than ducted because they condition one space. For heating, Australian Government guidance describes reverse cycle as the most energy-efficient heater of all types.
