The share of energy-efficient inverter air conditioners touched 31 per cent during the first six months of 2017, a new high since their introduction in the country.
While the sale of ACs fitted with smart compressors have been on a rise for some time, the recent surge is attributed to manufacturers' growing interest in the segment. Thanks to the new energy-efficiency norms, to take effect from January next year.
LG is one company to have completely moved towards inverter split ACs. Others are preparing to align with the change. B Thiagarajan, joint managing director at Blue Star, says: "Realignment of manufacturing lines is not an issue; technologically, we are fully prepared."

According to Ajay Seth, head of channel operations at Panasonic India: "We will be expanding our product portfolio in the inverter AC segment and have witnessed five per cent growth compared to last year."

Globally, use of inverter ACs is on a rise. Unlike a normal AC, inverter ACs work primarily on smart compressors that reduce wastage of power due to thermostat cutoffs. In Japan, all ACs work on inverter technology; in China, 60 per cent. In India, the share of inverter ACs was four per cent in early 2015, rising to 12 per cent during January-June 2016. The size of the AC market, however, is still quite low at 4.5 million units a year, compared to a little over 40 million in the largest market, China.
