7.1 kWLG DUALCOOL AI 7.1kW Split System
7.1 kW rated cooling (1.85 to 7.5 kW range) and 7.7 kW heating for big living areas and open-plan spaces, the largest of the Smart wall units before the WH large-capacity models take over.
Part of the LG DUALCOOL with AI Air range, LG's split system line, in 6 sizes. Running costs below use the Sydney median rate; the Eastern Suburbs and Western Sydney pages cost systems on their own network tariffs. Check the size against your rooms, compare it with other 7.1 kW options, see every 7kW split system ranked by running cost, or ask about supply and installation.
About $564 a year at the current Sydney median electricity rate: $192 of cooling plus $372 of heating, from the official GEMS test figures.
The LG DUALCOOL AI 7.1kW uses 579 kWh per year for cooling and 1123 kWh per year for heating, based on official government test data for Sydney's climate zone. The system carries a 3.5-star energy rating for cooling and a 2-star rating for heating under the zoned energy label. Running costs depend on your electricity rate and how much you use the system.
Efficiency is measured by the AEER rating of 3.22 for cooling and ACOP rating of 3.66 for heating. The unit operates on R32 refrigerant. Your actual energy consumption will vary based on your home's insulation, how you set the temperature, and seasonal weather patterns.
