Ducted roof-mounted units cost a little more to service because of the roof access. A pre-summer service also checks the water system for leaks that can damage ceilings.
Service an evaporative cooler before summer, dirty or degraded pads cool poorly and can smell musty. A service also catches water leaks that could otherwise stain or damage a ceiling.
Ways to save
- Book the service before summer for the best price and to be ready when it is hot.
- Replace pads on schedule, old pads cool poorly and affect air quality.
- Fit a winter cover to protect a ducted unit from the elements when not in use.

What a evaporative cooler service costs in Perth
An evaporative cooler service in Perth is a common pre-summer job, because the hot, dry Mediterranean climate is ideal for evaporative cooling, so a large share of Perth homes run a rooftop evaporative unit and service it each year. The visit is a per-callout clean and check centred on the pads, the water system and the fan: replacing or cleaning the pads, clearing the trough and pump, flushing mineral scale, checking the bleed and float valve and inspecting the motor, all to ready the unit for a long, hot summer.
The dry climate is exactly why evaporative works so well in Perth, cooling efficiently and cheaply through the long summer when the air is dry, so keeping the unit serviced matters for a home that relies on it. Perth's hard water can leave heavy mineral scale in the trough and on the pads, so descaling and a good flush are an important part of the service here. Wind-blown sand and dust can clog the pads and foul the unit, so a clean before summer restores airflow. The isolation of the WA market can stretch lead time for a specialist part, though a routine service is readily booked. Labour sits near the national average.
Servicing an evaporative cooler is a maintenance service, not a licensed building or WA Building Services trade, though the water connection is plumbing and the motor wiring is a licensed electrician's job if a fault needs repair. For a Perth home, the clearest way to price an evaporative cooler service is per callout around the pre-summer pad, pump and descaling check that keeps a much-relied-on unit efficient.
