Meaning of star rating of an Air conditioner.

● This star rating is provided for customer awareness by BEE (Bureau of Energy Efficiency.)

NOTE : This table is time bonded and it will be revised.        

Will the star rating increase the initial cost of ACs?


  •  In order to increase the energy efficiency, AC manufacturer needs to change the design parameters like increasing airflow, surface area of copper tubes and highly efficient compressor etc.


  • These initiatives lead to increase in the initial cost of the star rated ACs.


  • However, the life cycle cost (Running cost + initial cost) is substantially lesser than ACs not having any  star rating.


  • Purchasing a 5 star AC can minimize your payback period.
