The Fujitsu High Static 12.5kW carries a 2.5-star energy rating for both cooling and heating under the zoned label for Sydney's climate zone. Based on official government test data for that zone, calculated in June 2026, the system uses 1192 kWh per year for cooling and 1813 kWh per year for heating. At the median Sydney residential electricity rate of 34.7 cents per kWh, that works out to around $414 for cooling, $629 for heating, and roughly $1043 across both seasons combined.
On the efficiency side, the unit has a rated AEER of 3.28 for cooling and an ACOP of 4.08 for heating, meaning it delivers more than three or four units of output for each unit of electricity consumed. The system uses R32 refrigerant.
