Fresh-air cooling built for summer 

Evaporative air conditioning takes a different approach to cooling your home. Instead of continually recirculating indoor air, the system draws in outside air, cools it via evaporation, and distributes it throughout your home. It’s particularly suited to hot, dry conditions where fresh airflow is part of staying comfortable.

What to weigh up with evaporative cooling

Evaporative air conditioning works differently from refrigerative systems, so your local climate, home layout and ventilation all matter when deciding whether it suits your home.

Temperature Changes

Your local humidity levels

Evaporative cooling is best suited to hot, dry conditions. Higher humidity can reduce its cooling effect, so the local climate should be considered before installation.
Evaporative systems

Airflow through your home

Evaporative systems rely on continuous airflow. Doors or windows need to be open while the system runs so warm air can escape as fresh, cooled air enters.

Your cooling expectations

An evaporative cooler provides fresh-air cooling rather than refrigerated temperature control. Consider the level of cooling you expect during the summer.

See how we calculate this

The figures above are Trimech own estimates, based on patterns we've observed across our internal job records tagged to Evaporative air conditioning jobs - not an independent industry study. Parts required will vary by cause and property.

What does evaporative cooling cost?

The cost of evaporative air conditioning varies with the system, home and work required. Trimech can assess your property and provide a quote based on the actual installation or service needed.

Installation costs to consider

For ducted evaporative cooling, current estimates put complete supply and installation at around $3,000–$6,000+. More complex roof-mounted installations can increase labour and ductwork costs, so an on-site assessment provides a more accurate figure.

  • Standard ducted units: $2,300–$3,500
  • Premium ducted units: $3,500–$5,000+
  • Ducted installation: $600–$5,000
  • Complete ducted system: $3,000–$6,000+

Servicing and running costs

Evaporative systems also have ongoing servicing, water and electricity costs. Estimates place professional maintenance at roughly $180–$400, depending on the system and work required, while individual replacement components can add to the total.

  • Professional maintenance: $180–$400
  • Replacement cooling pads: $80–$200
  • Water system cleaning: $80–$150
  • Estimated annual running costs: $300+

Frequently asked questions

Still weighing up evaporative cooling? These answers cover some of the practical questions homeowners ask about climate, airflow, servicing and choosing the right system.

Does evaporative cooling work in humid weather?

Evaporative cooling performs best in hot, dry conditions. When humidity rises, the cooling effect can be reduced because the air has less capacity to absorb additional moisture.

Do I need to leave windows open with evaporative ACs?

Yes. Evaporative air conditioning relies on airflow through the home, so selected windows or doors should remain open to allow warm air to escape while fresh, cooled air enters.

How often should an evaporative cooler be serviced?

Regular servicing helps keep the system clean and operating effectively. The right schedule can depend on the system, its usage and condition, so Trimech can advise on suitable ongoing maintenance.

Can evaporative cooling cover my whole home?

Ducted evaporative cooling can distribute cooled air across multiple rooms through ducts and ceiling vents. The right system size and layout will depend on your home and cooling requirements.

Is evaporative better than reverse cycle?

They work differently. Evaporative cooling relies on fresh airflow and performs best in dry conditions, while reverse-cycle air conditioning provides refrigeration-based heating and cooling. The better fit depends on your home, climate and comfort needs.
