What it costs to run

The LG DUALCOOL AI 3.5kW uses 275 kWh annually for cooling and 473 kWh annually for heating under official GEMS test conditions for Sydney's climate zone. These figures reflect typical household usage patterns in your area and form the basis for running cost estimates on this page. The system carries a 3.5-star cooling efficiency rating and 2.5-star heating efficiency rating for Sydney.

Efficiency is measured by AEER (3.67) for cooling and ACOP (3.90) for heating. The system uses R32 refrigerant. Your actual energy consumption will vary depending on how often you run the unit, your temperature settings and your home's insulation. The running cost calculator above applies current Sydney electricity rates to the official annual energy figures to show expected costs.
