- Energy rating (cooling)
- 1.5
- Heating: 0.5
- Annual electricity use
- 1,642 kWh
- 226 cooling + 1,416 heating
- Estimated running cost
- $542 / year
- $45 / month · $5,419 over 10 years
- Capacity
- 2.8 kW cooling
- 2.5 kW heating
6% more electricity than the median of 21 comparable 2.5 kW reverse cycle window / wall registrations (1,546 kWh a year) in the cold zone. Uses less than 10% of them.
Across all 3,611 air conditioner registrations sold in Australia, it uses less than 79% (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 cold zone (Canberra climate: Canberra, Hobart, Ballarat, alpine areas). All of New Zealand is the cold zone on the Zoned Energy Rating Label. Cost = kWh × 33c/kWh in NZD; change the price above to your tariff.

| Mixed zone | 889 | $293 | $2,934 |
| Hot zone | 1,096 | $362 | $3,617 |
At 33c/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.
