Evaporative cooling adds moisture and needs windows cracked open to work, so it performs poorly in humid coastal climates. In dry inland climates it is cheap and effective.
Evaporative cooling costs much less to run than refrigerated air conditioning because it only uses a fan and water pump, but it cannot cool below a certain point in humidity.
Ways to save
- Install before summer, cooling installers are cheapest and most available in the cooler months.
- Size the unit to the house, an undersized unit runs flat out and still underperforms.
- In a dry climate, evaporative is far cheaper to buy and run than refrigerated ducted, match the system to your climate.

Installing ducted evaporative cooling in Australia typically costs around $3,500 to $7,000 in 2026 for an average single-storey home, with double-storey and large homes running higher. It is usually cheaper to install than refrigerated ducted air conditioning.

What a evaporative cooling installation costs in Adelaide
An evaporative cooling installation in Adelaide is a well-suited whole-house job, priced by the size of the home and the number of ceiling outlets the ducting feeds, so a larger house needs a bigger rooftop unit, more duct and more outlets. The affordable labour that marks the city out keeps the ducted install the cheapest of any mainland capital, which matters because a whole-house evaporative system is a labour-heavy run of ducting. The install covers the rooftop unit, ducting, outlets, a water line and wiring.
Adelaide's hot, dry Mediterranean climate suits evaporative cooling well, so it is a common and sensible whole-house choice that cools cheaply through the long, hot summer, and the cheap labour makes the up-front install more affordable than in the dearer capitals. Adelaide's water can leave scale, so a bleed-off or treatment may be part of the setup. The city's single-storey homes and stone cottages with accessible roof spaces often take ducted evaporative easily, though a solid-walled heritage cottage can complicate the outlet runs. The cold winters mean a separate heater is still needed, as evaporative does nothing for heating. The dry summer is when the system does its work.
Installing evaporative cooling is licensed in parts: a licensed plumber connects the water supply and a licensed electrician wires the unit, under Consumer and Business Services for the electrical side, with the ducting and roof penetration part of the install. For an Adelaide home, the clearest way to price an evaporative cooling installation is by the home size and the outlet count, with the cheap local labour keeping the whole-house ducted install affordable.
