Energy rating (cooling): 3.5; Heating: 2.5
Annual electricity use: 1,114 kWh; 397 cooling + 717 heating
Estimated running cost: $356 / year; $30 / month · $3,565 over 10 years

2% more electricity than the median of 240 comparable 5 kW reverse cycle split system registrations (1,093 kWh a year) in the mixed zone. Uses less than 38% of them.

Across all 3,680 air conditioner registrations sold in Australia, it uses less than 74% (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.
