12% more electricity than the median of 196 comparable 3.5 kW reverse cycle split system registrations (709 kWh a year) in the mixed zone. Uses less than 25% of them.
Across all 3,680 air conditioner registrations sold in Australia, it uses less than 83% (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.
Fujitsu AOTH12KNCA running cost by climate zone
| Climate zone | kWh / year | Per year | 10 years |
|---|---|---|---|

| Mixed zone | 791 | $253 | $2,531 |
| Hot zone | 872 | $279 | $2,790 |
At 32c/kWh. Formula: cost = annual kWh × price. The kWh figure is the label’s residential estimate for that zone; commercial-profile figures are in the specifications.
