HOW EVAPORATIVE AIR CONDITIONING WORKS

Harnessing the power of nature for cooling

Evaporative air conditioning cools your home by using the process of evaporation. Warm, dry air is drawn in from outside and passed through water-soaked pads, cooling the air before it circulates indoors.

This system not only lowers temperatures but also adds humidity, making it especially effective in dry climates. Energy-efficient and environmentally friendly, evaporative systems provide a refreshing breeze while reducing electricity consumption.

EVAPORATIVE VS REFRIGERATED

Evaporative cooling vs refrigerated air conditioning

Evaporative cooling draws in fresh air and cools it through water-saturated pads — it's energy-efficient and well suited to Perth's dry summer heat. Unlike a refrigerated ducted system, it works best with windows or doors open, and doesn't provide heating.

If you want lower running costs and plenty of fresh airflow, evaporative is a great choice. If you need year-round heating and cooling, we'll talk you through the alternatives.

RUNNING COSTS & UPKEEP

What affects evaporative cooling cost and performance?

Installation cost depends on the size of your home, the number of vents, and whether existing ducting can be reused. Running costs are typically lower than refrigerated systems.

  • Home size and number of rooms to cool
  • New install vs reusing existing ducting
  • Pad condition and pump servicing

We recommend an annual service — ideally before summer — to keep airflow strong. Book a free quote or a service any time.

Frequently Asked Questions

Otter Air has developed a reputation amongst our clients as being honest, reliable, efficient and provide a professional service that delivers what we promise.

How does evaporative cooling work?

Evaporative cooling draws warm outside air through water-soaked pads, naturally cooling the air through evaporation. The cooled air is then distributed through your home via ducts, providing a refreshing, natural breeze.

Is evaporative cooling suitable for Perth?

Absolutely! Perth's hot, dry climate is ideal for evaporative cooling. These systems work best in low-humidity environments, making them perfect for our summer conditions.

How often should I service my evaporative system?

We recommend servicing before each summer season. This includes replacing cooling pads, cleaning the unit, checking the water pump, and ensuring all components are functioning properly.

How much does evaporative cooling cost to run?

Evaporative cooling is one of the most cost-effective cooling options available. Running costs are typically 50-80% less than refrigerated air conditioning, making it an excellent budget-friendly choice.

Can I use evaporative cooling with windows open?

Yes! In fact, evaporative cooling works best with some windows or doors slightly open to allow airflow. This is different from refrigerated systems which require a sealed environment.

Which brands do you install?

We supply and install leading evaporative brands including Brivis, Bonaire, Braemar, and Coolair. We can source specific models to suit your requirements.
