Is a 5 star AC worth it? Understanding energy consumption for ACs

The long hot summer days are here and if you are considering buying a new air conditioner for your house, you might have been intimidated by the dozens of specifications and models on the market. Undoubtedly, one of the most important things to consider is the power consumption and efficiency of the air conditioner. It is important to understand how star ratings can affect both the quality of air conditioning and the effect on your electricity bill. Whichever energy rating you decide is the best for you, with the Bajaj Finserv Market’s EMI store, you can have your brand new air conditioner delivered to your doorstep within 24 hours.

What is a star rating?

The star rating for any electrical appliance is an indication of its energy efficiency. The ratings range from 1 to 5, with 5 being the most energy efficient and 1 being the least. The more star ratings your air conditioner will have, the less energy it will consume and the lesser your electricity bill is likely to be. If your air conditioner has a higher star rating, it also means it is better for the environment, as it has been designed to release lesser harmful chemicals into the environment. As energy specifications are hard for customers to understand, the star energy rating system has been developed to make it easier for us to understand how energy efficient the product we are considering to buy will be.

How is the energy rating of an air conditioner determined?

Several factors influence the star rating of an air conditioner. For all appliances used for heating or cooling, the Energy Efficiency Ratio (EER) influences the star rating. The EER is the ratio of cooling capacity of the air conditioner to the total electrical input. The star ratings are universal and are provided by the Bureau of Energy Efficiency. Ideally, a five-star rated air conditioner should save about 20-22% of the power cost as compared to a one-star rated air conditioner.

Is a 5-star air conditioner automatically the better choice?

While looking at the above data, you might conclude that a 5-star air conditioner is automatically the better option for you, there are several factors that you need to take into account. For instance, if you are installing the air conditioner in a place that is humid and it will not be used a lot, a 3-star air conditioner might actually prove to be a better choice. If you have a restricted budget and do not want to opt for an air conditioner which will be used every day, a 3-star air conditioner will be best suited for your needs. Alternatively, if you live in an incredibly hot climate, where the air conditioner will be used for upwards of 8 hours every day, it is advisable to invest in a 5-star air conditioner. This will help you save costs tremendously in the long run.

In fact, a study conducted by the Center for Science and Environment revealed that even 5-star rated air conditioners perform like two-star air conditioners when the outside temperature is above 40 degrees Celsius due to higher power consumption. Similarly, if the temperature of your air conditioner is set below 27 degrees, its power consumption can rise, further damaging its energy efficiency. Hence it is very important to take into account usage when trying to decide which air conditioner to buy.

With the Finserv Market’s EMI store, you can have your brand new air conditioner delivered to your doorstep within 24 hours, and installed in merely two days. What’s more, is that you have to no downpayment and can completely hassle-free avail the 10-day replacement policy.
