Is evaporative cooling effective in Sydney?
Generally no. Sydney's coastal humidity often exceeds 60% in summer, making evaporative cooling ineffective. Split system or ducted air conditioning is recommended for most Sydney homes. Western Sydney may have some days suitable for evaporative cooling.

NSW offers the Energy Savings Scheme (ESS) which provides discounts on energy-efficient appliances including air conditioners. Some energy retailers offer additional rebates on efficient cooling systems.
Why is my house so hot in Western Sydney?
Western Sydney regularly experiences temperatures 5-10°C higher than coastal areas due to the urban heat island effect and distance from coastal breezes. External shading on west-facing windows is critical, as is adequate ceiling insulation (minimum R5.0 recommended).
