When purchasing an air conditioner, you may wonder what the difference between 3 star and 5 star AC is? This is a necessary factor to keep in mind when purchasing an AC. Read the blog below to know more about the reason why you should keep this aspect of air conditioners in mind while getting one and how it can benefit you.

Difference Between 3 Star and 5 Star AC

As the summer months approach, many homeowners begin to think about upgrading their air conditioners. There are many things to think about such as the size of your AC or the energy efficiency. If your AC is more than a few years old, you may be looking upgrade your AC, or consider investing in a new, energy-efficient model. There are several reasons why this is a good idea.

First of all, newer ACs use less energy, which saves you money on your utility bills. Additionally, they also emit less carbon dioxide and other pollutants, which is better for the environment.

Finally, newer models are often quieter and more comfortable than older ones. If you’re ready for a cooler, more efficient home, then it’s time to upgrade to an energy-efficient air conditioner. This is why understanding the difference between 3 star and 5 star AC is essential so you can make the right choice for your home and get the apt air conditioner for you and your family!

What is the Energy Efficiency rating system in India?

To understand the difference between 3 star and 5 star AC, you must first know what the EER is. The Energy Efficiency Rating (EER) is a voluntary label for commercial and residential equipment in India. The EER label provides consumers with a range of energy efficiency levels for different types of equipment. The EER label is voluntary, but the government has set minimum energy efficiency standards for certain types of equipment.

The Indian EER label includes the following information: type of equipment, make and model number, energy efficiency rating (in stars), air conditioner capacity (in tons), refrigerant type, and other important information. The EER label can help consumers compare the energy efficiency of different brands and models of equipment. It is important to note that the EER label does not include information on other important factors such as durability, quality, or price.

How is the energy efficiency rating calculated?

The energy efficiency rating of appliances in India is calculated by the Bureau of Energy Efficiency (BEE). The BEE is a government agency that promotes energy efficiency in the country. The rating system is based on the energy consumption of the appliance, and appliances are given a star rating from one to five, with five being the most efficient.

The ratings are meant to help consumers compare the energy efficiency of different appliances before making a purchase. For example, a five-star rated appliance will use less energy than a four-star appliance, and so on. Read this article on what is star rating in AC to understand this term better.

The BEE also has a voluntary labeling program for appliances that meet certain standards of energy efficiency. This label can be found on the appliance itself or in the manufacturer’s literature. Appliances that have this label are considered to be among the most efficient on the market.

All ACs in India must have a minimum BEE rating of 2 stars in order to be sold in the country. 3 star and 5 star ACs are more energy-efficient than lower-rated units, and thus, they will cost more upfront. However, over time, the savings on your energy bill will make up for the higher initial investment.

3 star ACs must have a minimum Seasonal Energy Efficiency Ratio (SEER) of 3.2, while 5 star ACs must have a SEER of 4.5 or higher. In terms of capacity, a 3 star 1 ton AC will use about 958 kWh of electricity per year, while a 5 star 1 ton AC will use only 810 kWh per year.

This difference may not seem like much, but it can add up over time, especially if you use your AC regularly. From a purely financial perspective, a 5 star AC will save you more money in the long run. It is also a good idea to invest in a voltage stabilizer for your AC for similar reasons – help it work well in the long run!

3 Star vs 5 Star Air Conditioner

The three main differences between a three-star and a five-star air conditioner are the noise levels, the amount of energy they consume, and the price.

Noise levels

Air conditioners are rated on a scale of 1 to 5 stars. The higher the number of stars, the more energy-efficient the AC will be. In terms of noise levels, 3-star ACs tend to be slightly quieter than 5-star ACs. However, the difference is not always significant.

It is important to note that noise levels can vary depending on the specific model of AC. Some 3-star ACs may be just as quiet as some 5-star ACs. When comparing noise levels, it is important to read reviews and compare test results for specific models of air conditioners.

Amount of energy consumed

In general, a 3-star AC will consume less energy than a 5-star AC. This is because the 3-star AC has a lower power rating and is thus more energy efficient. However, there are other factors that can affect energy consumption, such as the size of the unit and the climate.

In cooler climates, a 3-star AC may use more energy than a 5-star AC, due to the need to run for longer periods of time. Therefore, it is important to consider all factors when choosing an AC unit. Ultimately, the best way to reduce energy consumption is to choose an AC unit that is appropriately sized for the space!


The main difference between a 3 star and 5 star AC is their price. A 5 star AC will cost you more to buy and run than a 3 star AC. But, a 5 star AC will also save you money in the long run. A 3 star AC is less energy efficient than a 5 star AC. So, over time, a 5 star AC will actually save you money on your energy bills.

In addition, a 5 star AC is better for the environment. Because it uses less energy, it produces fewer emissions that contribute to climate change. So, if you’re looking for an AC that’s both economical and environmentally friendly, a 5 star AC is the way to go.

Although 5-star air conditioners are more expensive, ultimately they are the better choice when it comes to picking between 3 star vs 5 star air conditioners.

FAQ about 3 Star and 5 Star AC:

Which is better – 3 star AC or 5 star AC?

If you’re trying to decide between a 3-star and a 5-star AC, there are a few things you should keep in mind. First, consider the climate in your area. If you live in an area with mild summers, a 3-star AC may be sufficient. However, if you live in an area with hot summers, a 5-star AC will be better able to keep your home cool and comfortable. Second, think about your budget.

5-star ACs are typically more expensive than 3-star ACs, so if cost is a concern, a 3-star unit may be the better option. Finally, consider your personal preferences. If you prefer a more powerful AC unit, a 5-star model may be the best choice for you. However, if you prefer a more energy-efficient unit, a 3-star AC may be the better option. Ultimately, the decision of which AC is best for you will come down to your personal needs and preferences.

Should I purchase a 5-star split AC over a 3-star one in terms of the electricity bill?

When it comes to choosing an air conditioner, there are a lot of factors to consider. One important factor is the unit’s Energy Efficiency Rating (EER). The EER is a measure of how much cooling a unit provides for the amount of energy it uses. You should know the difference between 3 star and 5 star AC.

A 5-star AC unit will have a higher EER than a 3-star unit, meaning it will be more efficient and cost less to operate. In addition, 5-star units often come with features that can further reduce your energy costs, such as variable speed fans and advanced temperature controls. As a result, investing in a 5-star AC unit can help you save money on your energy bills in the long run.


In conclusion, it is important to consider the difference between 3 star and 5 star AC when purchasing the appliance. The first is cost, as 5 star units will typically be more expensive to purchase and operate than 3 star units. Second is climate, as 5 star units will generally be more effective in hotter climates.

Finally, it is important to consider your individual needs and preferences, as some people may prefer the features and amenities of a 5 star unit despite the higher cost. Ultimately, the decision between a 3 star and 5 star AC depends on a variety of factors, and there is no one-size-fits-all answer.
