Climate zone

Electricity pricec/kWh

Energy rating (cooling): 3.5
Annual electricity use: 120 kWh
Estimated running cost: $40 / year; $3 / month · $396 over 10 years
Capacity: 2.5 kW cooling

2% less electricity than the median of 17 comparable 2.5 kW cooling only split system registrations (123 kWh a year) in the cold zone. Uses less than 59% of them.

Across all 3,611 air conditioner registrations sold in Australia, it uses less than 100% (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.

Mitsubishi Electric running cost by climate zone
