- 2.5 kW cooling
- 3.5 kW heating
17% less electricity than the median of 191 comparable 2.5 kW reverse cycle split system registrations (543 kWh a year) in the mixed zone. Uses less than 91% of them.
Across all 3,680 air conditioner registrations sold in Australia, it uses less than 95% (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.
Hitachi RAC-VJ25NHAE running cost by climate zone
| Climate zone | kWh / year | Per year | 10 years |

| Mixed zone | 450 | $144 | $1,440 |
| Hot zone | 426 | $136 | $1,363 |
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.
