With rapid advancement in technology air conditioners efficiency is also increasing that is why the BEE, Govenment of India updates the star rating of ACs with every 2-4 year.
ISEER stands for Indian Seasonal Energy Efficiency Ratio. This is a metric to determine the energy efficiency of an air conditioner. An appliance with higher rating depicts that the particular AC is highly power efficient, this means it will consume less electricity to cool the same room.
Please check the below iseer rating charts for checking the AC ratings of the corresponding year.
The below table is for split air conditioners. This table is valid for the year 2021-2023
| Star Level | Minimum | Maximum |
|---|---|---|
| 1 Star | 3.3 | 3.49 |

In the above image left table is for window air conditioner and the right table is for split air conditoner.
As you can see the window AC ISEER rating is very low compared to the ISEER rating of split ACs, the main reason is inverter technology. Now every company is making only inverter split ACs but the window AC is still using the non-inverter fixed speed compressor. Few brands like LG and Samsung have introduced dual inverter and triple inverter technology respectively.
LG is the most popular brand in the inverter split AC segement. If you are looking for highly efficient aircons for saving electricity then do check our highest iseer rating ac in the indian market.
