Climate zone

Electricity pricec/kWh

Energy rating (cooling): 3.5; Heating: 3
Annual electricity use: 1,405 kWh; 508 cooling + 897 heating
Estimated running cost: $450 / year; $37 / month · $4,496 over 10 years
Capacity: 6.3 kW cooling; 7.4 kW heating

5% more electricity than the median of 104 comparable 6 kW reverse cycle split system registrations (1,340 kWh a year) in the mixed zone. Uses less than 35% of them.

Across all 3,680 air conditioner registrations sold in Australia, it uses less than 66% (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.

Gree running cost by climate zone

Climate zone	kWh / year	Per month	Per year	5 years	10 years
Cold zone (Canberra, Hobart, Ballarat, alpine areas)	2,782	$74	$890	$4,451	$8,902
Mixed zone (Sydney, Melbourne, Adelaide, Perth)	1,405	$37	$450	$2,248	$4,496
