Evaporative Cooling done right

Evaporative cooling draws fresh air through water-cooled pads and pushes cool air through your whole home, so you can leave doors and windows open. It uses far less power than refrigerated cooling, which makes it a cheap, comfortable option for a Melbourne summer.

The detail

How evaporative cooling works, and when it is the right choice

Evaporative cooling draws fresh outside air through wet filter pads and pushes the cooled air through your home. It uses noticeably less electricity than refrigerated cooling and it constantly brings in fresh air. It also behaves very differently, so it is worth understanding before you choose it.

  1. Unit sizing and roof mountingThe unit sits on the roof and is sized to the air volume of the home. Undersizing is the usual reason an evaporative system disappoints on the hottest days.
  2. Duct and vent layoutOutlets are placed so air moves through the living areas and out through open windows or doors. The airflow path matters more here than in any other system.
  3. Water supply and drainageThe unit needs a plumbed water supply and a drain point. Modern units manage water use with automatic dump cycles to stop mineral build up in the pads.
  4. Why you leave windows openEvaporative cooling works by continually replacing the air inside the house. It needs somewhere for that air to escape, which is the opposite of how refrigerated cooling works.
  5. Commissioning and seasonal servicePads, water distribution and the pump are checked at commissioning, then serviced before each summer to keep the airflow and the water flow even.

Common questions

How is evaporative cooling different from refrigerated?

Evaporative cools by evaporating water into fresh outside air and needs windows open. Refrigerated cooling recirculates and dries the air inside a sealed house. Evaporative uses much less power, refrigerated performs better in humid weather.

Does evaporative cooling work on humid days?

It is less effective when humidity is high, because the cooling comes from evaporation. On Melbourne's dry northerly days it performs very well, which is most of our genuinely hot weather.

Does it use a lot of water?

Modern units are reasonably efficient with water and periodically dump and refresh to stop minerals building up in the pads. Water use is modest against the electricity it saves.

What maintenance does it need?

A service before each summer, with the pads checked and replaced when they harden or scale up. Pads are the part that quietly reduces performance as they age.

"We have had Efficient Air install 4 Hisense reverse cycle units over the last 12 months. Each time had been a trouble free experience. Jason and Kelly have been great to deal with. The installation crews have been on time and completed their work without fuss."

"I have always had a great experience when needing services and products from Efficient Air. I have had split systems and radiators from them and the service has been very good. The split system keeps us cool in summer and warm in winter which is what we need right now in Melbourne!"

Will your place cope with the first 38 degree day?

Four things worth checking now, while there is still time to do something about them. Two of these are a service, not a new system, and we will tell you which one you are looking at.

  • It struggles once the day passes 35 degrees.A system that cools fine in spring but never quite gets there in a heatwave is usually undersized for the space rather than faulty.
  • Some rooms never cool down.Normally a zoning or ductwork problem, not a reason to replace the whole system. Worth having someone look before you spend.
  • It has not been serviced since last summer.Filters and coils that have sat through winter are the most common reason a system underperforms on the first hot day.
  • It is more than ten years old.Older units lose capacity and cost more to run each summer. That is the point where replacing can be cheaper than another repair.
