Electricity pricec/kWh

Energy rating (cooling): 4; Heating: 3
Annual electricity use: 584 kWh; 193 cooling + 391 heating
Estimated running cost: $187 / year; $16 / month · $1,869 over 10 years
Capacity: 2.6 kW cooling; 3.2 kW heating

8% more 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 24% of them.

Across all 3,680 air conditioner registrations sold in Australia, it uses less than 91% (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.
