In this post, we are going to discuss everything related to Best 1.5 ton highest ISEER rating AC in India. AC efficiency is measured by the Indian Seasonal Energy Efficiency Ratio (ISEER). ISEER measures the cooling capacity of an air conditioner in relation to its power input. In general, an air conditioner with a higher rating uses less energy. Thus, when purchasing an air conditioner, it is important to consider the ISEER and BEE star ratings.
It can be quite difficult and time-consuming to pick the right air conditioner. Generally, air conditioners use a significant amount of energy, which brings up many questions in a buyer’s mind. Where can I find the best 1.5 ton split inverter AC?, What is the most energy-efficient AC? What type of AC is energy-efficient? and others.
So, if you plan on buying an air conditioner and have many questions, this article is exactly what you need. All the important factors that you should consider when buying an air conditioner have been compiled into one place. The star label may also be useful when searching for the best 1.5 ton inverter Split AC.
Based on the ISEER values of the ACs available in the market, we reviewed a lot of options. After much confusion regarding air conditioners and their overall features, we selected the top 6 1.5 ton highest ISEER rating AC in India 2022.
What is ISEER Rating?
ISEER rating is calculated by taking the cooling seasonal total load into account, a measure of the heat removed by the air conditioner. The ISEER is equal to Cooling season total load (CSTL) divided by Cooling season energy consumption, i.e., 1600 hours in temperatures between 23°C and 43°C.
However, EER, short for Energy Efficiency Ratio, is another method of rating. Air conditioners are measured according to their EER by dividing their BTU (British Thermal Unit) by their wattage. For instance, the EER rating of a 12,000 BTU air conditioner powered by 1,000 watts is 12 (12,000/1,000 = 12).
What is the difference between EER and ISEER value?
Difference Between EER and ISEER Value. In other words, a measure of an air conditioner’s efficiency is the EER or SEER. In general, an AC unit with a higher EER or SEER will be more efficient.
| EER Value | ISEER Value |
| An international standard | It has been approved by the Indian government |
| Air conditioners without inverters rated | Ratings for inverter air conditioners |
| The number of hours does not depend on the season | Seasons play a huge role in this |
| There is no change in value around the world | Changing Indian temperatures |
| In comparison to ISSER, ISER is less accurate | High accuracy compared to EER |

What to look for when buying a highest ISEER rating 1.5 ton ac?
Buying an highest ISEER rating AC in India can be a challenging process. To make the best decision, you need to consider some important factors. ISEER measures your AC’s efficiency, and the higher the rating, the more efficient it will be. The ISEER rating of an air conditioner is one factor you should consider while buying it.
Noise:
In order to relax from the heat, you do not want to be subjected to loud and destructive noises. Noise is an important factor to consider when shopping for a new air conditioner. With the split AC, there are chances that you will not have a problem with noise. Window air conditioners are generally quiet, but if you were to purchase one,
The noise from the machine may disturb you, particularly during sleep or when doing other activities. No matter which type of air conditioner you choose, it is important to check the noise level. Pay attention to both outside and indoor units’ noise details in DB.
ISEER rating:
It is very important to check the ISEER rating. The higher the rating, the more energy efficient your AC will be. This ratio is referred to as seasonal energy efficiency. ISEER is a measure of how energy-efficient an air conditioner is, measured in unit of energy used.
Air Quality:
Check the quality of the air provided by your AC next. For the room to be cool and comfortable, you should have a good dehumidification system. During the monsoon season, air conditioners that have good dehumidifiers provide better cooling and greater comfort.
Cooling speed:
When purchasing an air conditioner, look for a thermostat that can be adjusted, two fans, and variable speed, since this will allow you to adjust the temperature at various times of the day. In other words, you can enjoy your AC to the fullest while using the least amount of energy.
Review:
While purchasing an AC, you should also make sure that the product is free of complaints and has an excellent reputation. Buying AC isn’t something you do every month or every season. In order to be certain that the product will last long, one should check for the product’s complaints and reviews.
Warranty:
Among the most important factors to consider, when buying an AC is whether the brand offers a warranty. It reduces the cost of repairs in case of a manufacturing defect.
Copper condenser coil:
Make sure that your AC has an in-built PM and anti-dust filter that can remove pollutants from the air and improve air quality. Copper coil condenser ACs can provide better cooling, and they require little maintenance.
BEE’s 2019 star rating table indicates that; in India, inverter air conditioners with an ISEER rating of 4.50 and above are considered to be five-star air conditioners.

Frequently Asked Questions (FAQ’s):
Is 5 a good ISEER rating for a 1.5 ton AC?
I believe its a good score, almost a very high score. The difference is only marginal if you compare 5 to 5.50 or something different in point. You will find alloy to be more expensive, but dont go for alloy, the money you save will go for maintenance only since alloy has frequent gas leaks, and it becomes corroded eventually, which will set you back another 9000.
Look for 100% copper condenser coil, followed by 3 or 4 or 5 stars. The number of stars varies from model to model. It is challenging to make a decision as there are several factors that impact the energy consumption, including the outside temperature, the size of the room, the type of air conditioner, and the efficiency of the unit. Energy meters need to be connected to AC inputs. Take previous readings & after running air conditioning for 8 hours. Calculate the difference to find unit consumption. Measure the consumption at various temperatures of the room. If you invest 6000 more for 5 star, compare it to how much you will save each day in daily life.
Which is better for a house, a 3-star or a 5-star AC?
Choose an inverter air conditioner with five stars. Their prices differ by between 5k and 7k.
The long run benefits would outweigh the short-term disadvantages. The power consumption of 5 star ACs is much lower than 3 star ACs.
When buying an AC for the drawing room, you should opt for a non-inverter model because inverters are less effective in the drawing room compared to the bedroom because there are more doors opening in the drawing room than in the bedroom and some houses have a drawing room attached to the kitchen. It would be suitable to use non-inverter AC there.
After a quick 1 day study I found out that, in average a 5 star 1.5-ton AC of 2022 consumes 1400W. And 3-star 1.5-ton AC of 2022 consumes average 1700W.
Use- 9 hours/day * 30 days i.e., 270 hours a month.
Unit consumption in a 5-star AC = (1400 X 270 / 1000) units i.e., 378 units
Unit consumption in a 3-star AC = (1700 X 270 / 1000) units i.e., 459 units
So, the difference is (459–378) units i.e., 81 units. Now, if 1-unit costs you Rs. 8, then bill difference will be Rs. (81×8) i.e., Rs. 648 per month which is Rs. 7776/year.
I have 1 ton Ac of LG installed on my bedroom, now I am looking for 1.5 ton. Though LG has slightly low ISEER rating than Daikin, but my experience on their after sales is satisfactory. They quickly response on my company.
Kindly, share annual maintenance cost of Daikin and 1.5 ton?
