What is ISEER, and how is it beneficial for me?

So, ISEER stands for Indian Seasonal Energy Efficiency Ratio, which simply means it is the ratio of the total amount of the heat that can be removed from the ambience by the AC in a year to the energy the AC consumes in a year.

It is a standard that has been set by the Bureau of Energy Efficiency to calculate the energy efficiency of the AC. The more the ISEER rating, the more energy your AC saves. As simple as that. 

There is another popular method of calculating the efficiency of the AC called the EER, which stands for Energy Efficiency Ratio, which is where the BTU is divided by the wattage.

For example, an average A1 ton AC removes 12,000 BTU per hour, and it consumes about 1000 watts, so divide the 12,000 by 1,000, and you get 12. The SEER rating of your AC is 12.

But ISEER is the best methodology for us Indians as it is approved by the government of India, and also ISEER value is more accurate and is dependent on the climatic changes as well, unlike EER rating.

Things to look for before buying an AC with Highest ISEER Rating

  • ISEER Rating – ISEER stands for Indian Seasonal Energy Efficiency Ratio, which is used to measure the energy efficiency in air conditioners. The higher the ISEER value, the lower the power consumption. Which leads to saving money in electricity bills. So we have to carefully check about the ISEER rating while buying an AC.
  • Energy Consumption – Energy Consumption means the amount of electrical energy used while operating the appliance. The measuring unit is W/kW. While purchasing, we need to check about the wattage as if the wattage is higher, it consumes more energy. It results in increased cost in electricity bills.
  • Inverter Technology – Inverter Technology allows the compressor to operate at different speeds and capacity, based on the cooling requirements. Inverter AC’s are more energy efficient and help to enhance the lifespan of an AC unit. It also provides quieter or noiseless operation. So, it becomes a mandatory choice while choosing an AC.
  • Tonnage – We have to choose effective and efficient AC tonnage according to the room size and number of people in it. Tonnage ranges from 0.75 to 5.5 tons. 
  • Noise Levels – Noise level refers to the amount of noise an AC unit generates while it’s operating. The measuring unit is decibels (dB). Excessive noise can be annoying and make us disturbed. The recommended quiet noise level ranges from 30 to 40 dB. So better check the noise level, as this is an X factor which causes sleep disturbances, stress and other health issues.
  • Energy Efficiency Labels(BEE) – BEE stands for Bureau of Energy Efficiency, which is an Indian government agency. Which provides a label with its logo to ensure the customer that the appliance meets the energy efficiency standards. It also provides an estimate of the product’s annual energy consumption for users to understand the long-term electricity cost.
  • Convertible – Convertible Technology often used in Split AC’s, which allows us to adjust the cooling mode into different stages based on the specific cooling needs, room size and outside temperature. The stages may vary according to the brand and model. Which reduces energy consumption and improves efficiency.
  • Installation & Maintenance – We need to check whether they provide free installation or if it is chargeable. We have to cross-check the service availability for maintenance, repair or replacement.
  • Brand and Warranty – As it is a huge investment, we need to check the brand, model and warranty period. We need to find out the warranty claim process and warranty coverage whether they offer repair or replacement.
  • Price – We have to decide the budget for the air conditioner that best suits our specific needs and preferences under the budget.
  • Additional Features – We need to also check whether the air conditioner provides additional features such as Wi-Fi, Convertible, Air Purification Filter, Anti Bacterial Filter, Dehumidifier, Dust Filter, Fast Cooling, High Density Filter, etc.,

    Please send your suggestion as soon as earliest possible

    • Hi Mohan Gopal Sharma,

      Probably, ISEER rating only applicable for Split AC, so if you are planned to pick good window ac choose high star rating along with AMC.
