The Bureau of Energy Efficiency (BEE) has a star rating methodology called Indian Seasonal Energy Efficiency Ratio (ISEER) for air conditioners.
ACs with higher star ratings will consume much less power, thereby saving money on your electricty bill in the long run.
Energy Star Rating
The higher the Indian Seasonal Energy Efficiency (ISEER), the more the savings from your AC.
Annual Electricity Consumption
Under standard conditions, this is the amount of electricity your AC would consume, if left running for a year. Electricity costs values across the country. Multiply the units by the rate to arrive your annual cost.

Higher star ratings cost a bit more initially but consume much less power, and hence save money on your electricity bill in the long run. in the AC Compressor material also contributes to energy consumption. Compressors made of copper are more energy efficient than aluminium ones.
Below are estimated calculations on power consumption for a 1.5 ton capacity AC. Values will vary for other capacity & ISEER rating combinations
|Star||ISEER Rating||Power Unit Consumption||cost||Yearly Savings||% Saving|
|for 1600 hrs usage||(@%6/unit)||(vs 3 Star)||(vs 3 Star)|
Below table shows the expected savings on buying split ACs with 3 or more energy star ratings. Values given are basis ISEER energy label on 1.5 Ton Voltas ACs (for 1600 hours of operation) & electricity charges of Rs.6 per unit. Kindly note that non-inverter Split ACs do not come in 4 and 5 energy star rating.
|Type||Energy Star||Approx. annual energy||Annual electricity||Annual|
