It depends on your needs. Reverse cycle systems provide both heating and cooling, work well in all climates (including humid days), and offer precise temperature control. Evaporative cooling is more affordable to run and works best in dry heat, but it’s less effective on humid or rainy days — which are common in Melbourne.

Evaporative cooling uses less electricity and is cheaper to run. However, reverse cycle systems are more energy-efficient in terms of performance, especially when used for both heating and cooling — and they maintain consistent comfort all year round.

Evaporative systems are ideal for dry inland climates. In Melbourne’s changing weather — where humidity can rise — reverse cycle air conditioning is more reliable, especially for year-round comfort.

Evaporative Cooling: Uses water to cool air and relies on open windows for airflow; cheaper to run but climate-dependent.

Reverse Cycle AC: Uses refrigerant and a compressor; offers heating & cooling; more versatile, efficient, and suitable for all seasons.

For most homes in Melbourne, reverse cycle split systems or ducted units are a better long-term investment. They provide heating and cooling, perform well in varied conditions, and are eligible for government rebates through the VEU program when installed by trusted providers like Melbourne Aircon Specialist.
