Cooling and energy use

BEE rates it 5 star on the 2026 table.

The BEE label puts annual consumption at 1017.08 kWh, measured on the standard 1,600 hours of use; your bill depends on your hours, thermostat setting and tariff. Rated at full load: 5,000 W of cooling and 1,520 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. Convertible modes: 4-in-1 (it can run at lower capacity to save power when the room needs less).
