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 Sydney
An evaporative cooler service in Sydney is charged as a callout, a flat visit fee to clean, check and ready one rooftop or wall unit for summer, so the price turns on the unit and its condition rather than any area. The service centres on the cooling pads, the water system and the fan: the technician replaces or cleans the pads, checks and clears the water trough and pump, flushes mineral scale, checks the bleed and float valve, and inspects the fan and motor, which is the routine a pre-summer service follows.
Evaporative coolers are less common in Sydney than in the dry inland cities, because they work by evaporating water into the air and struggle in Sydney's humid summers when the air is already moist, so many Sydney homes use refrigerated air conditioning instead. Where an evaporative unit is fitted, a once-a-year service before summer keeps it hygienic and efficient, because stagnant water left in a trough over winter can grow bacteria and scale. The city's highest trade rates lift the callout, and a terrace or home near the salt air of the coast has its rooftop unit checked for corrosion at the same visit.
Servicing an evaporative cooler is a maintenance service, not a licensed building trade, though the water connection is plumbing and the motor wiring is a licensed electrician's work if a fault needs repair, under NSW Fair Trading. A basic pad clean a handy owner can do, but the plumbed water and roof access make a professional service sensible. For a Sydney home, the clearest way to price an evaporative cooler service is per callout around the pre-summer pad, pump and water check.
