About the same electricity as the median of 9 comparable 2.5 kW cooling only window / wall registrations (327 kWh a year) in the mixed zone. Uses less than 22% of them.

Across all 3,680 air conditioner registrations sold in Australia, it uses less than 98% (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.

Mixed zone 327$105$1,046
Hot zone 961$308$3,075

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.
