FAQs
It draws warm air through water-soaked pads, cooling it down naturally before circulating it throughout your home for fresh, breezy comfort.
Evaporative systems work best in dry conditions. On humid days, they’re less effective, so they’re ideal for Perth’s typically dry climate.
No, evaporative air conditioning is designed solely for cooling. If you need heating as well, you’ll need to pair it with a separate heating system or consider a reverse-cycle air conditioner.
Pricing depends on factors like the size of your space, how many rooms need cooling, and your chosen brand. We’ll provide a solution that fits your property and budget.
How long does it take to install evaporative air conditioning in Perth?
Yes, you can adjust the cooling flow by closing windows in certain rooms and opening internal doors to redirect the air. We recommend experimenting to find what works best for your space. Just remember, proper ventilation with an external exhaust is key to making evaporative cooling work effectively.
Not necessarily. Instead of opening a window or door, you can install security vents or relief ducts that exhaust air from the building. We supply and install these options too, so you can still enjoy effective cooling without leaving your home exposed.
No, as long as your system is designed with balanced ventilation in mind. Keeping doors and windows open or using an exhaust fan helps release any humid air, ensuring your space stays comfortable without unwanted moisture buildup.
It’s normal if your system has a water management feature like ’Watermiser.’ This system monitors the water quality and only drains when needed, replacing it with fresh water. Older units may have a bleed-off drain that constantly drips a small amount of water while running to maintain water quality.
Evaporative coolers are an energy-efficient alternative to standard air conditioning. For example, according to a 2020 study by Canstar Blue, a 5-10kW unit uses around 413 watts per hour, while a 10-15kW system uses 734 watts. For medium-sized homes, a 10-20kW system is usually ideal.
