Energy rating (cooling): 4; Heating: 2
Annual electricity use: 2,017 kWh; 198 cooling + 1,819 heating
Estimated running cost: $666 / year; $55 / month · $6,656 over 10 years
Capacity: 4.2 kW cooling; 5.4 kW heating

45% more electricity than the median of 187 comparable 3.5 kW reverse cycle split system registrations (1,395 kWh a year) in the cold zone. Uses less than 5% of them.

Across all 3,611 air conditioner registrations sold in Australia, it uses less than 77% (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.
