If you plan to buy an air conditioner, you must choose which one is the best one for you. You must have indulged in the fight of difference between 3 stars and 5 Star Inverter AC. Please read this article extensively to know how 3 star AC differs from the 5 Star Energy Rating in AC.

3 Star vs 5 Star Energy Rating in AC

It will give you a brief idea of the Energy Star ranking of air conditioners. If you are still uncertain about which of the 3 star vs. 5 star AC to consider for purchase, this article will help you.

We live in an era where having an AC is a basic need for Indian families. But as far as India’s climate is concerned, particularly in summers, AC is considered the basic necessity. Moreover, you will find ACs not only in our houses, but in cars, restaurants, hotels, and several other places.

There is no doubt that AC absorbs tons of energy, and thus it goes against nature. But there is continuous advancement in the ACs and their characteristics. Therefore, they are becoming more pleasing to nature.

The usability of the AC is also improved by having heating pumps in some models. It can help us avoid using room heaters in our homes during winters. Finally, the Government’s ongoing study of the energy efficiency of each AC model uses the same.

What does Star Rating in AC Means?

It is also known as an Air Conditioner Energy Rating, which means the cooling quality. Anyone can quickly learn about the characteristics and specifications of any AC. But it is somehow difficult to know precisely how much power an AC can absorb.

What does Star Rating in AC Means?

The Bureau of Energy Efficiency, or BEE, is a department focusing on energy saving. And it is controlled by the Indian Government. By using it, customers can get some idea about the power consumption of a specific AC model. 

Compared to one without the energy ratings, there are many advantages to purchasing a star rated AC. The explanation is clear! It will help one understand that the company has already checked the AC for its energy consumption based on its cooling capacity.

You will need all the information to know the critical Difference between the energy rating of 3 stars and five stars in AC. Also, compared to low rating ones, a high star rated AC can condition a wide area’s air.

How To Know Star Ratings?

You must have seen a window shaped with a curved top sticker on the AC. You can see it on any appliance that consumes power or electricity.

Any newbie, one who does not have any idea about it, looks a bit complicated or technical. Simultaneously, it is easier for one to grasp the device’s energy usage by glancing at the sticker.

Therefore, the most significant thing is to look at the sticker to see how many stars it comprises. However, you can see these stars in the curved portion right at the top of the sticker. If you see only one star, then that appliance or AC’s energy star rating is only 1, and so on. “More Stars More Savings” is written at the core of those stars to give consumers information.

Besides, if you want to go through the AC’s energy efficiency use specifics, then look at the highlighted box in orange. It gives the exact ISEER measure. Although, anyone can read the actual rating given to the appliance by the BEE.

How To Calculate Energy Efficiency Ratio?

SEER means Seasonal Energy Efficiency Ratio of India. We may refer to it as the ratio you use to measure the two variables of any air conditioner. One is the net amount of heat that it absorbs from the inside of the room. 

The company measures it per hour in British thermal units or BTUs. Second, the net energy consumption is calculated in watts by the equipment to do the same. So, if we divide the first measure into the second, the result is called the Air Conditioner’s SEER ratio for energy efficiency.

Do Star Ratings Affect The Cost of Air Conditioner?

No wonder, for a high star rated AC, you will have to pay more. Similarly, with a smaller star air conditioner, you have to pay less. Why is there a cost gap, and is it right to look forward to buying an AC valued five stars? Well, all this stuff would certainly leave anyone confused.

To increase their energy efficiency, manufacturers should make improvements to the design parameters of ACs. They can achieve it using a highly powerful compressor by adjusting the copper pipes’ surface area. So both of these tweaks will raise the AC price. But looking for long term savings, you would gain the most from a 5 Star rated AC.

So, as a heavy user of an AC, we compare the initial running expense. In the initial years, you will certainly cover the extra cost you pay to buy a 5 star AC than less star ACs. So, it will reduce the payback time, all in all.

There is also a recent amendment from India’s Ministry of Power. It will set the default temperature of twenty-four degrees Celsius for all forms of air conditioners. It will start from 1 star to 5-star ratings. As of this year, it is already operational. It is an approach to saving electricity for individuals who are usually confused about what temperature to maintain on ACs inside their home.
