Based on the Indian Weather Data Handbook, 2014, weather profiles for 54 major cities show that over 65% of the daytime hours are over 24 degrees Celsius (5778 hours out of 8760). To date, air conditioners have been tested in India under the IS 1391 standard at temperatures outside of 35°C. Manufacturers are given star ratings based on the results of their tests based on the above standard.
