The Natural, Clean Way to Cool Your Whole Home.
Perth experiences some of the driest, hottest summer days in Australia. While refrigerated systems recirculate dry, recycled indoor air and produce hefty power bills, evaporative cooling introduces continuous, naturally filtered fresh air cooled through high-density water pads.
Whether you need to replace an aging, rusted rooftop cooler on your existing ductwork or design a completely new multi-outlet system from scratch, Eracon Perth ensures seamless dropper sizing, leak-free roof flashings, and maximum airflow efficiency for every room.

Why Perth Chooses Eracon for Evaporative Cooling
We combine certified refrigeration, electrical, and plumbing expertise to ensure your rooftop cooler runs silently, efficiently, and trouble-free for years.
Whole-House Fresh Breeze For A Fraction Of The Energy
Unlike conventional reverse cycle AC units that compress chemical refrigerants at high electrical demand, evaporative cooling works through simple, powerful physics: water evaporation and ultra-efficient DC inverter fan motors. You can run your evaporative system all day and night with zero bill shock, keeping your doors and windows open so kids and pets can freely move in and out.

Fast Rooftop Unit Changeovers
Got an old, rusted Bonaire, Celair, or early Breezair? We seamlessly replace old units using your existing roof penetration and ductwork within a single day.
Water Management & Auto-Drains
We configure smart automatic dump valves to periodically purge mineral deposits and eliminate stagnant water, preventing calcium crust and pad degradation.
Allergy & Asthma Friendly
Continuous outside air circulation flushes out dust mites, cooking fumes, and indoor allergens, replacing stale air with fresh, naturally moist airflow every 2 minutes.
The Evaporative Difference
How natural open-flow evaporative cooling outperforms recirculated refrigerated systems on Perth’s hottest, driest summer days.
Recirculated Reverse Cycle
- Closed House Trap: Must seal every door and window tightly, trapping pet dander, cooking smells, and recycled indoor CO2.
- Severe Air Dehydration: Mechanically extracts indoor moisture, causing dry eyes, sore morning throats, and dehydrated skin.
- High Energy Peaks: Compressing chemical refrigerants demands 3,000W to 5,500W of electrical power on 40°C days.
100% Fresh Air Evaporative
- Doors & Windows Wide Open: Positive displacement drives warm, stale air out, keeping kids and pets free to come and go outdoors.
- Gentle Natural Humidity: Water-cooled honeycomb pads replenish moisture, protecting respiratory comfort during dry Perth easterlies.
- Up to 85% Power Reduction: Only runs a whisper-quiet DC fan and miniature low-voltage water pump (typically 400W–750W).

Inside Modern Evaporative Technology
Modern evaporative cooling has evolved drastically beyond old noisy tin units. Today’s systems incorporate precision automation, smart water quality monitoring, and ultra-high-density honeycomb evaporative matrixes.
High-Density Chillcel Honeycomb Pads
Interlocking corrugated cellulose maximizes water saturation contact surface, achieving up to 93% saturation cooling efficiency.
Smart Water Quality Management System
Auto-drain valves test water salinity and flush out mineral build-up regularly, preventing scale crusting and keeping water fresh.
Inverter DC Whisper Motor & Aerofoil Fan
Variable-speed digital DC motor delivers massive airflow using a fraction of typical grid power with near-silent roof operation.
Leak-Proof Custom Metal Roof Flashings
Custom fabricated flashings matched precisely to your roof profile (Colorbond or tile) with our 5-year watertight guarantee.
The 4-Hour Rooftop Changeover Process
Got an old, rusted cooler on your roof? Here is how seamlessly our Perth team swaps out your tired system for a high-efficiency new cooler in a single morning.
Safe Decommissioning & Removal
We isolate electrical circuits and water feeds, drain the basin, and safely lower your old rusted chassis for free eco-disposal.
Dropper & Flashing Inspection
We inspect your existing roof penetration, re-seal flashing seams with premium non-shrink butyl, and ensure airtight dropper alignment.
Mounting & Plumbing Hookup
The new polymer unit is mounted, plumbed with quick-fill solenoids, connected to auto-drain dump lines, and hardwired to modern specs.
Pad Pre-Wet & Airflow Test
We wet the honeycomb matrix, balance diffuser sweep through every room, calibrate your digital wall controller, and leave your home spotless.
Evaporative vs. Reverse Cycle: Running Cost Comparison
When temperatures hit 38°C in Perth, reverse-cycle ducted air conditioners draw thousands of watts to keep compressor coils cold. Here is how the power bills compare over a typical Perth summer:
Refrigerated Ducted (14kW)
Estimated Summer Operating Cost
$1,350 – $2,100 / season
Modern Inverter Evaporative
Average Seasonal Energy Bill
$150 – $290 / season

Evaporative Cooling FAQs
Clear guidance on rooftop installations, unit changeovers, operating costs, water consumption, and maintenance across Perth.
Need quick advice?
Call 0402 570 293Yes — in fact, you should! Evaporative cooling relies on positive airflow displacement. The system pushes large volumes of cool, fresh outdoor air through your ceiling vents, which pushes warm, stale air out through open windows or doors. This prevents humidity build-up and creates a refreshing natural breeze through your home.
Yes! This is known as a rooftop unit changeover. If your ceiling ducts and diffusers are in sound condition, we can crane or lift off your old unit, adapt the existing roof dropper, install a modern high-efficiency cooler, and connect modern digital controls. It usually takes just 3 to 5 hours.
Modern evaporative coolers are exceptionally water-efficient. On a typical hot summer afternoon in Perth, a unit consumes between 15 to 25 litres of water per hour. In WA water tariff terms, that equates to roughly $0.30 to $0.60 of water per day — far outweighed by the massive electricity savings.
We install Australia's leading evaporative brands including Breezair (Seeley International), Braemar, Coolair, Bonaire, and Celair. We help you choose the right capacity and pad technology for your roof style and roof color matching.
Yes. All new installations and changeovers include up to a 5-year manufacturer warranty on the equipment, plus Eracon's full workmanship guarantee covering droppers, flashings, plumbing connections, and electrical wiring.
