When purchasing an air conditioner, one of the most important things to remember is the star rating. But what is a star rating in AC? We tackle the answer to this question below, as we take a more in-depth look at what exactly these ratings mean and why you should remember to check them before you purchase an AC for your home!

What Is Star Rating in AC

Star ratings are used by air conditioning professionals to indicate the relative comfort and effectiveness of different models of ACs. These ratings provide a reference point for consumers looking to purchase an air conditioner, making it easier to compare different products and identify those that will best meet their needs.

The Importance of Energy Efficiency

India is a tropical country, and air conditioners are necessary for many people here. There are many types and brands of ACs to choose from. However, traditional air conditioners are very energy-intensive, which has led to an increase in energy bills for consumers and a strain on the power grid.

As a result, there is a growing interest in energy-efficient air conditioners. These units use less electricity to operate, which can lead to significant savings for consumers.

Another reason energy efficient appliances are getting popular is their environment-friendly nature. Energy-efficient appliances help to protect the environment in several ways. First, they consume less energy, which reduces the amount of greenhouse gas emissions that are produced. Second, they often use less water than traditional appliances, which helps conserve this vital resource.

Third, energy-efficient appliances usually last longer than their traditional counterparts, generating less waste over time. Finally, energy-efficient appliances can help save money on utility bills, freeing up resources that can be used to invest in other green initiatives. In short, there are many good reasons to switch to energy-efficient appliances. We can all help to make a difference in the fight against climate change by doing so.

Energy efficient ACs put less strain on the power grid, helping to prevent blackouts during periods of high demand. As India continues to experience rapid economic growth, it is essential to adopt more energy-efficient technologies like these air conditioners to meet its growing energy needs.

What is Star Rating & How is it Decided?

What is a star rating in AC?

Star rating in air conditioners, also known as energy efficiency rating, is a scale used to measure the amount of power that an appliance uses. India Bureau of Energy Efficiency (BEE) introduced the star rating program for room air conditioners in 2006. The program was voluntary at first but became mandatory in 2009.

These ratings are typically given on a scale from 1 to 5 stars, with five stars indicating the most energy-efficient and one star indicating the least. Several factors, including ISEER, are considered by the BEE when awarding the rating so you have an excellent idea of whether or not you should purchase the AC.

By choosing air conditioners with higher ISEER ratings or higher star ratings, you can help to reduce your energy consumption and lower your utility bills. Ultimately, this makes it possible to enjoy cool comfort without breaking the bank.

What is ISEER and why is it relevant to star rating in AC?

Indian Seasonal Energy Efficiency Ratio (ISEER) is a metric used to compare the efficiency of air conditioning systems in India. It is calculated by dividing the output of an air conditioning system during Indian seasons by the power consumption during the same period.

The Indian government’s Bureau of Energy Efficiency (BEE) has established reference outdoor temperature guidelines for different regions of India to help consumers compare the efficiency of different products.

Products with a higher ISEER rating are more efficient and receive more stars on the BEE’s star rating system. Higher efficiency ratings can help consumers save money on their energy bills, as well as reduce their carbon footprint.

How to find the star rating in AC?

The star rating of your air conditioner is an essential piece of information that you should be aware of if you want to ensure that your system is running at peak efficiency. There are a few different ways to find the star rating of your air conditioner.

One option is simply to check the manual that came with your unit. If you no longer have this manual, or if it doesn’t list the star rating, you can typically find this information on the manufacturer’s website or by searching online for customer reviews and ratings.

Another option is to contact a local HVAC professional who can assess your system and provide you with a star rating based on its age and current condition. No matter which method you choose, finding out your air conditioner’s star rating will help you get the most out of your system and improve your overall comfort.

3 Star vs 5 Star Rating:

3-Star AC Models

One advantage of 3-star air conditioners is that they are very energy efficient. This means that they will cost less to operate than older, less efficient models. In addition, 3-star air conditioners tend to be more durable and last longer than lower-rated models. This can save you money by reducing the need for repairs or replacements.

However, there are also some potential disadvantages to consider. First, 3-star air conditioners may not be as powerful as some other models on the market. If you live in extreme heat, you may need a more powerful unit to keep your home cool. In addition, 3-star air conditioners may cost more upfront than lower-rated models. 

5-Star AC Models

A 5 star air conditioner is considered one of the best available, offering superior performance and efficiency and many other benefits. For example, these units tend to be highly durable and long-lasting, reducing the need for frequent repairs or replacements. 

Additionally, they typically consume less energy than lower-rated models, potentially reducing operating costs over time. Overall, 5-star air conditioners have numerous advantages that help to make them an attractive choice for homeowners or business owners.

At the same time, there are also several potential drawbacks associated with these units. These air conditioners tend to be relatively expensive compared to other options on the market. Additionally, they may produce more noise than lower-rated models when running at maximum capacity. 

How to pick between the two?

Choosing between a 3-star AC and a 5-star AC can be difficult. On the one hand, 3-star models are typically cheaper and more affordable for those on a budget. They also use less energy and may be easier to install, making them a popular choice for many homeowners. 

On the other hand, 5-star models are generally more robust and offer greater cooling capacity. They also tend to have more advanced features, including built-in humidifiers or air purification systems that can help improve air quality in the home. 

Ultimately, choosing between a 3-star and 5-star AC will depend on your specific needs and requirements. If you are looking for more excellent performance at an affordable price, a 3-star model is probably the best choice. However, if you want top-of-the-line features and high energy efficiency, a 5-star AC is perhaps your best bet.


A star rating is simply a measure of how energy-efficient an air conditioner is. The more stars, the more efficient the unit is. A higher rating means that the unit costs less to operate, which can save you money on your energy bills. In addition, units with higher ratings tend to have lower carbon dioxide emissions, which is better for the environment.

Now that you know what is star rating in AC is, when shopping for an air conditioner, be sure to check the star rating so that you can choose the most efficient model for your needs.

FAQs About Star Rating:

1. Should you purchase a 5-star AC or a 3-star AC?

There is no clear-cut answer to this question, as choosing between a 5-star and a 3-star AC depends on several factors. On the one hand, a 5-star AC tends to be more powerful and more efficient in energy consumption. However, it is also typically more expensive than other models, making it less suitable for those on tighter budgets.
