Harness the natural power of water evaporation to cool your home — fresher air, lower running costs, and a smaller environmental footprint for hot, dry Australian climates.
Evaporative cooling is a natural air cooling technology that uses the physical process of water evaporation to reduce the temperature of the air flowing through your home. Unlike refrigerated air conditioning — which uses a compressor and refrigerant gas to mechanically transfer heat — an evaporative cooler draws hot, dry outside air through water-saturated cooling pads. As the air passes through, the water evaporates and absorbs heat from the air, lowering its temperature before it is distributed into your living spaces.
The result is a continuous supply of fresh, cool, and slightly humidified air — not recirculated indoor air, but genuine fresh air drawn from outside. This is one of the defining advantages of evaporative cooling, and a key reason why many people find it more comfortable and healthier than refrigerated air conditioning.
Evaporative cooling is most effective in hot, dry climates with low relative humidity — making it ideally suited to inland Victoria, South Australia, Western Australia, and inland New South Wales, where summer days are intensely hot but the air is dry rather than humid.
Hot, dry climates — inland Victoria, SA, WA, inland NSW. Not suitable for humid coastal areas.
Delivers real fresh outside air — not recirculated indoor air like refrigerated systems
Water evaporation absorbs heat from the air — no compressor, no refrigerant gas needed
Requires windows or doors slightly open — allows warm air to escape and be replaced
No refrigerant gases — cools using water and uses substantially less electricity
The same refreshing sensation you feel stepping out of a swimming pool on a hot, windy day — replicated at scale throughout your home.
A powerful fan draws hot, dry outside air into the evaporative cooler unit, which is mounted on the roof of the property.
The hot air is forced through large, highly absorbent cooling pads continuously wetted by a water distribution pump. Water evaporates rapidly as hot dry air passes through, absorbing heat from the air stream.
Evaporation removes a significant amount of heat from the air and reduces its temperature substantially before it enters the duct system. The air also gains a small amount of moisture — making it feel fresher and more comfortable.
Cooled fresh air is delivered through insulated ducts and ceiling vents into every room of the property — consistent, comfortable coverage throughout the whole home.
Windows or doors are kept slightly open so the warm, stale indoor air can escape and be continuously replaced by the cooled fresh air from the system — creating a gentle, natural airflow throughout the home.
Understanding the different types of evaporative cooling systems helps you choose the right solution for your property, climate, and budget.
The most popular type for whole-home coverage. A central unit is installed on the roof, connected to insulated ducts distributing cooled air through ceiling vents into every room. Even, consistent cooling throughout the entire home, controlled from a wall switch or smart controller.
Most PopularDelivers air from the cooler directly into the duct network — no zone dampers. Simple, reliable, and cost-effective for standard residential applications where whole-home coverage without zone control is the requirement.
Simple & ReliableA more sophisticated ducted system with motorised zone dampers allowing different areas to be opened or closed independently. Direct cooled airflow only to occupied areas — particularly useful in larger homes where some areas are unoccupied during the day.
Zone ControlFreestanding self-contained units requiring no installation — move from room to room as needed. Suitable for individual rooms, home offices, garages, or outdoor entertaining areas. Require a water connection or manual refilling.
No InstallationAn evaporative unit added to an existing ducted gas heating system, using the same duct network for heating in winter and cooling in summer. A cost-effective way to add summer cooling capability without installing a completely separate duct network.
Cost-Effective UpgradeFor households in hot, dry climates, evaporative cooling offers a unique combination of natural comfort, low running costs, and environmental responsibility.
Evaporative coolers use only the energy needed to run the fan and water pump — no compressor required. Running costs are substantially lower than a refrigerated system of equivalent capacity, particularly during long, hot summers.
Delivers a constant supply of fresh outside air — not recirculated indoor air. This reduces stuffiness, dilutes airborne allergens and pollutants, and creates a more natural, comfortable indoor environment.
Adds a small amount of moisture to the air — beneficial in very dry inland climates. Prevents the dry throat, dry eyes, and dry skin that some people experience with refrigerated air conditioning.
No refrigerant gases used — cools using water, a natural resource. Substantially lower electricity consumption means a meaningfully smaller carbon footprint. One of the greenest ways to stay cool.
Ducted evaporative systems are generally less expensive to purchase and install than equivalent ducted refrigerated systems — attractive for budget-conscious homeowners and new builds in suitable climate zones.
Delivers cooled fresh air to every room through ceiling vents — whole-home coverage comparable to ducted refrigerated air conditioning, with all equipment on the roof and only vents visible inside.
Evaporative cooling encourages a more open, ventilated style of living. You can keep windows and doors slightly open without losing your cooling — creating a natural, breezy feeling throughout the home.

Evaporative Cooling Brands We Install, Service & Repair
Unlike refrigerated air conditioners — where neglect mainly reduces efficiency — a neglected evaporative cooler can develop hygiene issues as scale, algae, and bacteria accumulate in the water system and on the pads. Annual servicing before each season ensures clean, fresh, healthy air from day one.
The right choice depends entirely on where you live and what you need. Here is an honest side-by-side to help you decide.
Reduced cooling often means worn or clogged pads no longer absorbing water effectively, a blocked water distribution system, or scale restricting airflow through the pads.
A musty, earthy, or stale smell indicates mould, algae, or bacterial growth in the water system or pads — a hygiene issue that requires prompt attention.
Rattling, squealing, or grinding from the cooler indicates a mechanical fault — typically a worn belt, failing fan motor bearing, or loose components.
Water dripping onto the roof or ceiling indicates a water system fault — most commonly a float valve not shutting off correctly, blocked bleed-off line, or cracked reservoir.
Noticeably reduced airflow may indicate a clogged pad blocking fan output, a disconnected duct, or an underperforming fan motor.
Even if everything seems normal, a cooler not serviced since last season may have scale and biological growth in the water system. Running it distributes contaminated air through your home.

Honest answers to the most common questions about evaporative cooling — how it works, when it works best, and how to maintain it.
Evaporative cooling performance is directly affected by outside humidity. On low-humidity days it works very effectively. Above approximately 50 to 60 percent relative humidity, the cooling effect reduces — the air cannot absorb as much water vapour. On very humid days, a refrigerated air conditioner will provide more consistent comfort.
It depends on local water quality and usage. In areas with hard water, pads may need replacing annually due to scale. With softer water and regular maintenance, pads may last two to three seasons. Your technician will inspect them during the annual service and advise on replacement.
No — evaporative cooling requires windows or doors to be slightly open so warm indoor air can escape. If the home is sealed, the cooled air has nowhere to go and the system quickly loses effectiveness. A small gap of 5 to 10 centimetres is usually sufficient.
Generally not recommended simultaneously. Evaporative cooling adds moisture to the air while refrigerated cooling removes it — running both at once creates conflicting conditions and causes both systems to work harder for reduced results. Use whichever best suits the current outside conditions.
Yes — evaporative cooling uses water to cool the air. However, the increase in water costs is typically offset by the reduction in electricity costs compared to refrigerated air conditioning. In most cases the overall running cost of an evaporative system remains lower than a refrigerated equivalent.
Evaporative coolers can be installed on most standard roof types — tiled, corrugated iron, Colorbond, and flat roofs. The installation method varies by roof type. Our technicians assess the roof during the consultation and advise on the most appropriate method for your property.
