- Capacity
- 5.2 kW cooling
12% more electricity than the median of 25 comparable 5 kW cooling only split system registrations (388 kWh a year) in the mixed zone. Uses less than 20% of them.
Across all 3,681 air conditioner registrations sold in Australia, it uses less than 96% (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.

| Hot zone | 1,258 | $403 | $4,026 |
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.
