14% more electricity than the median of 122 comparable 10 kW reverse cycle split system registrations (2,236 kWh a year) in the mixed zone. Uses less than 15% of them.

Across all 3,680 air conditioner registrations sold in Australia, it uses less than 42% (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 Γ— 32c/kWh in AUD; change the price above to your tariff.

Cold zone 4,901$1,568$15,683
Mixed zone 2,543$814$8,138
Hot zone 2,991$957$9,571

At 32c/kWh. Formula: cost = annual kWh Γ— price. The kWh figure is the label’s residential estimate for that zone; commercial-profile figures are in the specifications.

Air conditioners that use less electricity

Same configuration and type, cooling capacity within 12% of 10 kW, at least 3% lower annual kWh in the mixed zone.
