Evaporative Cooling
Money and environment-saving evaporative cooling
Evaporative air conditioning is the lowest cost cooling option for your home, both in terms of initial outlay and ongoing costs. Quiet and efficient, evaporative air cooling is very popular in Australian homes.
Benefits of ducted evaporative cooling
- Low Emissions (lower electricity costs)
- Environmentally Friendly
- Can Cool Whole House
- Allergy Friendly
- Uses Fresh Air

An evaporative cooling system comprises a central roof-mounted unit connected to a duct system throughout the house. The unit draws in fresh air from outside the house, passing it through moistened pads, which lowers the temperature of the air and filters it before it flows into your home.
Evaporative cooling systems in the home
Being a natural process, evaporative cooling systems do not require the use of refrigerant chemicals and do not dry out the air. The evaporative air conditioning system ensures a constant flow of fresh air through your home – more like a refreshing sea breeze than a refrigerator.
Ducted evaporative cooling can help eliminate smoke and cooking odours from the home and helps indoor plants thrive. The constant flow of fresh air provided also means that bacteria and dust in the air is expelled, making it a more allergy-friendly system.
Unlike refrigerated systems, evaporative air cooling requires you to keep windows and doors open. For families, this means that children running in and out of the house are not a problem.
Modern evaporative air conditioning units are also extremely quiet, which means that the only disturbance to a good night’s sleep this summer will be the sound of crickets.
Evaporative air cooling: cheap and green
Ducted evaporative cooling is cheap to install and can have a running cost that is up to seven times lower than an equivalent refrigerated system. In fact, systems can be run for less than $1 per day!
In addition, evaporative cooling systems can produce less than 15 per cent of the greenhouse gases produced by an equivalent refrigerated system, which means that you’re helping the environment as well. Many modern units also incorporate water-saving technologies, making them even better suited to the drought-conscious Australian market.
