Cooling and energy use

BEE rates it 5 star on the 2026 table. Its ISEER (Indian Seasonal Energy Efficiency Ratio, the figure behind the BEE stars) is 5.77; a higher ISEER means less electricity for the same cooling over an Indian summer. The BEE label puts annual consumption at 684.4 kWh, measured on the standard 1,600 hours of use; your bill depends on your hours, thermostat setting and tariff. Rated at full load: 5,100 W of cooling and 1,140 W of power input. The inverter compressor changes speed instead of switching on and off, which is why inverter ACs use less power over a long evening. LG says it keeps cooling at outdoor temperatures up to 55 °C. Convertible modes: 6-in-1 (it can run at lower capacity to save power when the room needs less).
