The air conditioners are given a star rating by the BEE (Bureau of Energy Efficiency), which defines their efficiency. The more the number of stars, the better its energy efficiency. Using 5-star air conditioning systems helps achieve lower electricity bills, increased energy efficiency, and reduced environmental impact.5-star rated ACs often have advanced features such as better filtration systems and improved airflow. They also have a better life expectancy compared to lower-rated ACs. You should even consider that post-pandemic, many people are working from home. AC usage extends usual hours in this case. Hence using a 5-star rated air conditioner is beneficial for energy efficiency. Additionally, you can recover the cost of a 5-star AC within 1-2 years.
