Climate zone

Electricity pricec/kWh

Energy rating (cooling): 4; Heating: 2.5
Annual electricity use: 1,752 kWh; 619 cooling + 1,133 heating
Estimated running cost: $561 / year; $47 / month · $5,606 over 10 years
Capacity: 8.5 kW cooling; 9 kW heating

4% less electricity than the median of 125 comparable 8 kW reverse cycle split system registrations (1,834 kWh a year) in the mixed zone. Uses less than 77% of them.

Across all 3,680 air conditioner registrations sold in Australia, it uses less than 56% (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)	3,551	$95	$1,136	$5,682	$11,363
Mixed zone (Sydney, Melbourne, Adelaide, Perth)	1,752	$47	$561	$2,803	$5,606
