With rising summer temperatures, picking the right air conditioner is more important than ever. Choosing between a 3 Star AC and a 5 Star AC can be confusing—but understanding their differences can help you make an informed and energy-efficient choice.
Difference between 3 Star and 5 Star ACs: Which is Better?
The key difference lies in energy efficiency and electricity consumption. A 5 Star AC typically consumes less power than a 3 Star AC while offering similar cooling. It is costlier upfront, but more economical over time.
What is the Star Rating in ACs?
Star ratings are issued by the Bureau of Energy Efficiency (BEE) to indicate an appliance's power efficiency. The higher the star rating, the more efficiently the AC runs. A 5 Star-rated AC uses significantly less energy compared to a 3 Star unit for the same tonnage. The BEE star ratings are crucial for assessing an AC's energy efficiency, a key component of HVAC systems.
