The hot Indian summer means only one thing: rising temperatures and increasing discomfort! To survive the summer heat without breaking into a sweat, buying the best AC is a must. While you have a number of options to choose from, regularly using an AC can increase your monthly electricity bill. As a result, it’s important to pick an AC with a good star rating. If you’re wondering what is difference between 3-star and 5-star ACs, read on to get all the information on your fingertips.

What is Star Rating in AC?

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 a range of 1 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 or any electronic device is 5, and the lowest star rating is 1. A 5-star air conditioner 5 will cool your room in the most efficient manner. To elucidate, this rating means that a 5-star AC will cool a particular room faster, while using lesser electricity than a 3-star 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 possibility. A star-rated appliance, like an AC, allows you to save on electricity costs more efficiently.

Comparison Between 3 Star vs 5 Star AC: Which is Better?

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.

Benefits of 5 Star Air Conditioners

In monetary terms, the difference between 3-star and 5-star AC 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. Therefore, the total cost of ownership (TCO) of a 5-star AC is lower in the long run as compared to that of a 3-star AC.

How much Electricity does 3 Star and 5 Star ACs Consume?

One of the key difference between the two variants is that how much electricity does 3 Star and 5 Star ACs consume once installed. An air conditioner’s electricity consumption depends on its EER rating. The 5 Star ACs are more energy efficient than a 3 Star AC unit. The electricity consumption of a 5 star AC (1.5 ton) is approximately 1.5 unit per hour; whereas a 3 Star AC (1.5 ton) consumes 1.6 unit every hour.
