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, or ask about supply and installation.
About $492 a year at the current Sydney median electricity rate: $167 of cooling plus $325 of heating, from the official GEMS test figures.
The LG DUALCOOL AI 7.1kW uses 579 kWh annually for cooling and 1123 kWh for heating, based on official GEMS test data for Sydney's climate zone. These figures reflect typical household use patterns in your area and let you calculate running costs using your local electricity rate. The system carries a 3.5-star cooling efficiency rating and a 2-star heating rating under the zoned energy labelling scheme.
The LG DUALCOOL AI achieves an AEER of 3.22 for cooling and an ACOP of 3.66 for heating. It uses R32 refrigerant. Your actual energy consumption will depend on how often you run the system, the temperatures you set, and how well your home is sealed and insulated.
