- Energy rating (cooling)
- 4
- Heating: 2
- Annual electricity use
- 3,166 kWh
- 340 cooling + 2,826 heating
- Estimated running cost
- $1,045 / year
- $87 / month · $10,448 over 10 years
- Capacity
- 7.1 kW cooling
- 7.8 kW heating
1% more electricity than the median of 203 comparable 7 kW reverse cycle split system registrations (3,143 kWh a year) in the cold zone. Uses less than 47% of them.
Across all 3,611 air conditioner registrations sold in Australia, it uses less than 59% (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.
LG AH24S2U running cost by climate zone
| Climate zone | kWh / year | Per year | 10 years |
|---|---|---|---|
| Cold zone | 3,166 | $1,045 | $10,448 |
| Mixed zone | 1,550 | $512 | $5,115 |
