Electricity pricec/kWh

Energy rating (cooling): 1.5; Heating: 0
Annual electricity use: 7,421 kWh
Estimated running cost: $2,375 / year; $198 / month · $23,747 over 10 years
Capacity: 67 kW cooling; 77.5 kW heating

54% less electricity than the median of 25 comparable 65 kW reverse cycle multi-split / vrf registrations (16,281 kWh a year) in the mixed zone. Uses less than 76% of them.

Across all 3,680 air conditioner registrations sold in Australia, it uses less than 11% (this compares very different sizes, so the cohort figure above is the useful one).

Annual kWh is the government label figure for a residential user in the mixed zone (Richmond NSW climate: Sydney, Melbourne, Adelaide, Perth). Mixed climate zone shown by default (Sydney, Melbourne, Adelaide, Perth); switch to cold or hot. Cost = kWh × 32c/kWh in AUD; change the price above to your tariff.
