- 1.5
- Annual electricity use
- 327 kWh
- Estimated running cost
- $108 / year
- $9 / month · $1,079 over 10 years
- Capacity
- 3.9 kW cooling
19% more electricity than the median of 8 comparable 3.5 kW cooling only window / wall registrations (275 kWh a year) in the cold zone. Uses less than 0% of them.
Across all 3,611 air conditioner registrations sold in Australia, it uses less than 97% (this compares very different sizes, so the cohort figure above is the useful one).
