3-star Acs Vs 5-star Acs- Which One Should You Buy This Summer?

  • Highlights

  • Star rating depicts the energy efficiency of appliances

  • The higher the rating, the more energy-efficient your AC is

  • 3-star ACs have a higher recurring cost

  • 5-star ACs require a larger upfront investment

With rising temperatures and increasing purchasing power, more individuals are buying air conditioners to help survive extreme weather conditions. However, while air conditioners are becoming easier to purchase, their regular use can increase your monthly electricity budget. As a result, manufacturers are now making ACs that are more energy efficient, a parameter that the common man understands as ‘star ratings’.

What is a star rating system?

A star rating system depicts the energy efficiency of an electrical appliance. The higher the number of stars, the more efficient it is. The star rating system was devised by the Bureau of Energy Efficiency (BEE) India, with the range from 1 star to 5 stars. This system ensured that the energy efficiency of appliances was easily understood by the common man.

A star rating takes two parameters in to account:
1. The cooling capacity, which is a measure of its ability to cool a room – this is expressed in British Thermal Units (BTU)

2. The Energy Efficiency Rating (EER), which is the amount of cooling it can provide using a certain amount of power

The highest star rating of an air conditioner of any electronic device is 5 and the lowest star rating is 1. An AC with a star rating of 5 will cool your room in the most efficient manner. Here, efficiency means that a 5-star rated AC will cool a particular room faster, while using lesser electricity than a 4-star or lower-rated AC.

How does knowing your AC’s star rating help?

An AC is not a one-time investment but has substantial recurring costs in the form of monthly or bi-monthly electricity bills. In a country as hot as India, a high electricity bill that can derail your budget is always a looming possibility. A star-rated appliance, like an AC, allows you to plan better and save on your electricity costs.

Comparing 3-star ACs with 5-star ACs

The star rating of an electrical appliance is quantified in the form of Energy Efficiency Ratio (EER). A 3-Star AC has an EER that ranges between 2.9 to 3.09 and a 5-star AC has an EER of 3.3 or above.


What it translates in to, in monetary terms, is that if the monthly electricity bill of a household with a 3-star AC is Rs. 580, keeping all variables constant, a 5-star AC would result in a bill of Rs. 500. 


The Total cost of ownership (TCO) of a 5-star AC therefore, is lower in the long run as compared to its 3-star counterpart.
