10 Best Highest ISEER Rated AC in India 2024

Our team of experts spent weeks testing 100+ options in highest ISEER Rated ACs at our dedicated lab. We tested them based on cooling capacity, smart features, durability, environmental impact, warranty and much more.

Do you want to cool off with a new air conditioner this summer? With the plethora of models available, it is hard to say which ones provide consistent value and performance. The ISEER ratings are what come in handy at this point. ISEER is a measure of the efficiency with which AC converts electricity into cooling power – a higher number implies that more energy gets converted. The Bureau of Energy Efficiency introduced the ISEER methodology in 2018 to offer a more accurate assessment of AC efficiency for Indian climatic conditions. In 2021, the top-rated split ACs scored ISEER scores of between 5.3 and 4.9 while conventional fixed speed ACs score from about a low as three point five to an average high of three point seven two which is equivalent to that achieved by inverter technology but with much less efficiency at lower loads because they do not have variable compression rat That’s 50% more efficient!
In this article, we will unveil the ACs that have got highest ISEER scores in. Spoiler alert – the top positions are taken by inverter ACs from brands such as Daikin, Hitachi, LG and Voltas. We selected the products after spending weeks examining and comparing all the worthy options in the market. Our research team took close look at all the important factors and included only the products which could stand tall in all necessary grounds.
Are you curious to know which models in particular are great? Then keep reading! We will count down the 10 highest ISEER-rated ACs with their tech specs and pricing.

Enhanced Performance:ACs with ISEER ratings are equipped with advanced technology and features that ensure better cooling performance and comfort.
Compliance with Regulations:Most parts of India have laws and standards where appliances must conform to certain energy efficiency criteria. An AC rated by ISEER guarantees compliance with these laws.

Now, let us try to understand the disadvantages of Owning an ISEER Rated AC in India:

Higher Initial Cost:The ISEER-rated ACs, due to their advanced technology and energy efficiency features may be more costly upfront than non-ISEER rated models.
Limited Model Options:Not all AC models may have an ISEER rating, which reduces the number of possible options that consumers can choose from when selecting a suitable air conditioner.
Maintenance Costs:The high-end technology in ISEER rated ACs may result to increased cost of maintenance due to repair or replacement of specialized components.
Potential Technology Learning Curve:There may be a learning curve for some consumers in adapting to and using all the features of an ISEER-rated AC.
Availability in Remote Areas:In some isolated areas, an ISEER-rated AC may not be readily available to consumers who value energy efficiency.


Keeping calm during the hot Indian summers is not an easy task. However, with a proper AC unit you can beat the heat in style. As we have already seen, the selection of an AC with a high ISEER rating guarantees maximum energy efficiency and lower electricity bills.
Models such as the LG 1 Ton and Panasonic 1.5 Ton Smart ACs with their sophisticated inverter compressors, WiFi connectivity and convertible cooling modes are ideal for personalized cooling needs. Their high-density filters and anti-bacterial coatings also cleanse indoor air. The brands like Voltas, Daikin and Blue Star have great 5 star rated split ACs with copper condensers for longevity.
Although cooling capacity and special features are essential, other factors such as installation requirements, stabilizer needs, noise levels and warranty terms should also be considered before selecting an AC. Smart ACs may require some learning but offer the ultimate convenience. Through our research, it was clear to us that, with the proper knowledge, one can get the best value for their money. With the same vision, we hope that this guide and our product recommendation will help you find the best ISEER rated AC for your home or office.
Lastly, you must note that as summers are getting hotter every year, buying a good ISEER rated AC with optimization features is the only way to stay cool inside and save on electricity bills. Select according to room size and enjoy the season with your new high-efficiency AC in natural comfort.
