Evaporative Cooling on the Gold Coast: An Honest Guide
What it is, when it suits, and what we recommend.
Evaporative cooling uses water and a fan to cool the air, with low running costs. It works best in dry climates. This guide explains how it works, its benefits, how it copes with Gold Coast humidity, and what Frost Solutions recommends instead for most coastal homes.

Evaporative cooling Gold Coast
Should you consider evaporative cooling?
Consider it if you want low running costs, like fresh air from open windows, and live somewhere with dry heat. On the Gold Coast, humid summer weather reduces how well it cools, so most coastal homes are better served by reverse cycle air conditioning, which also heats in winter.
There are good reasons people look at evaporative cooling: it is cheap to run, it uses no refrigerant, and it brings in fresh outside air. Those strengths are real. The catch is climate. An evaporative cooler cools best when the outside air is hot and dry, which is common inland but less so on the coast in summer.
How it works
What is an evaporative air conditioner?
An evaporative air conditioner cools air by evaporating water. A fan draws warm outside air through water-soaked pads; as the water evaporates it absorbs heat, so the air leaving the pads is cooler. That air is pushed through ducts into the house, and stale air escapes through open windows or doors.
Most home systems are a roof-mounted unit with ducts to ceiling outlets, similar in layout to ducted air conditioning. A pump keeps the pads wet and the water is topped up from the mains. Because the system adds moisture to the air, it needs a steady flow of air out of the house, which is why windows are left partly open while it runs.
Benefits
What are the benefits of evaporative cooling?
The main benefits are low running costs, because there is no compressor; fresh, filtered outside air rather than recirculated air; and a simple, refrigerant-free cooling process. It also works with windows and doors open, which suits people who like an open house.
Cost-effective
A fan and a small pump use far less power per hour than a compressor, which means lower running costs. The equipment is also relatively simple, which can keep the initial outlay down in a suitable home.
Fresh air
The system does not recirculate indoor air. Stale air is pushed out and replaced with outside air, so smells are not re-circulated, and the added moisture means the air does not feel dry.
Environmentally friendly
Cooling comes from evaporating water, with no refrigerant gas. It works with windows and doors open, and in winter the fan alone can freshen the air.
Gold Coast climate
Does evaporative cooling suit a Gold Coast home?
Often it does not suit well. Gold Coast summers are humid, and evaporative coolers lose much of their cooling effect when the air already holds a lot of moisture. On sticky days they can raise indoor humidity and leave rooms feeling clammy. They also cannot heat.
Where it can work
- Hot, dry days with low humidity
- Garages, workshops and sheds that need airflow more than cooling
- Households that keep windows open and accept some variation
Where it struggles
- Humid summer days and storms, common on the coast
- Homes that need to be closed up for security or noise
- Winter, when you need heating as well
- Salt air, which can corrode roof-mounted equipment
Our recommendation
What does Frost Solutions recommend instead?
For most Gold Coast homes we recommend reverse cycle air conditioning: ducted for whole-home comfort, or split systems for a few rooms. It cools and dehumidifies on humid days, heats in winter, and with an inverter and zoning it keeps running costs under control.
Frost Solutions designs and installs ducted air conditioning, split systems and multi-head systems with our own licensed technicians and electricians. If you have an old evaporative system and want to switch, we can assess the roof space and design a replacement.

Evaporative cooling questions
Frequently asked questions
Does evaporative cooling work on the Gold Coast?
It works on hot, dry days, but the Gold Coast's humid summers limit it. Evaporative cooling relies on dry air soaking up moisture; when the air is already humid, it cools less and can make rooms feel damp. Most coastal homes get more reliable comfort from ducted or split system reverse cycle air conditioning.
Is evaporative cooling cheaper to run than air conditioning?
Usually, yes, because it only runs a fan and a water pump, with no compressor. It also uses water. On humid days, though, it may not keep the house comfortable, so compare comfort as well as running cost. An efficient inverter reverse cycle system with zoning keeps running costs down too.
Can evaporative cooling heat my home in winter?
No. An evaporative cooler only cools. In winter the fan can circulate air, but you need a separate heater. A reverse cycle air conditioner heats and cools from one system.
Can you replace my evaporative cooler with reverse cycle air conditioning?
Yes, we install reverse cycle ducted and split systems, including as a replacement for an older system. The roof unit and its ducts are usually not reusable for refrigerated air conditioning, so we assess the roof space and design a new system. See air conditioning replacements.

Absolutely fantastic experience with Frost Solutions! I recently had a ducted air-conditioning system installed and honestly, from the very first conversation through to the finished installation, the whole process was seamless. ... The installation itself was done to a really high standard, the team worked efficiently and left everything clean and tidy. ... Great people, great communication, great workmanship and a great result.

Couldn't recommend Frost Solutions highly enough. We recently had them install a 16kW Daikin ducted system with 8 outlets, 6 independent zones, AirTouch 5, multiple upgrades and a 5 year service plan. ... Another big positive is that Frost Solutions have their own electrical team as part of the installation. ... the entire experience was seamless.

Frost Solutions installed ducted air conditioning in my home today and I couldn't be happier. The team were professional, friendly, punctual, and down to earth. ... left the house spotless ... I also really appreciated the follow-up call from the office later in the day to check I was completely satisfied ... They're a local business with local staff, and the value was extremely competitive for the quality of service and workmanship provided.

Thanks guys For installing my Panasonic 18 kilowatt Ducted air conditioning today. The guys turned up on time and were very polite. They worked hard all day, did a great job and left the house neat and tidy. Also they were $2000 cheaper than the others. :)

A massive thanks to Frost Solutions. We got a 16kw ducted system put in with 7 zones and 9 outlets. Tyrone and the team were super friendly and very professional doing an awesome job, even helping me to keep maximum space in our roof so I could do an attic room. They also decommissioned and removed 2 of our old split systems. Could not recommend them more highly.
