Which Air Conditioner to Buy: Difference Between 3-Star and 5-Star AC

Is buying an air conditioner on your list? Then, you must be confused about which one to buy considering the number of options available in the market. One of the main determining factors is the star rating of the AC. In this article, we will discuss about the difference between 3-star and 5-star AC

Overview of the Star Rating System

The star rating system essentially depicts the energy efficiency of an electrical appliance. The number of stars corresponds to its efficiency. The higher the number of stars, the more efficient the appliance will be. The range of the star rating system is 1 star to 5 stars. 

So, there will be a difference between a 3-star AC and a 5-star AC. In simple words, a 5-star AC would be more power-efficient than a 3-star AC.


What Do the Stars on the AC Mean?

  • More the Stars, Better the Cooling Capacity
  • A 5-star AC performs much better than a 3-star AC and functions optimally as it reduces energy consumption. It is also environmentally friendly and cools the room faster than a 3-star AC. 

  • Higher Rating, More Savings
  • As you go higher up with the ratings, the more energy will be saved. On average, a 5-star air conditioner can save up to 28% more energy than a 3-star air conditioner. 

    You can calculate the total amount of heat the AC eliminates with the total amount of energy it consumes to do that task. A higher rating equates to better efficiency. 

  • Higher Rating, More Powerful
  • The AC with a higher rating is more powerful. It also cools more effectively and consistently. Even though it’s powerful, it generates less noise.

Which AC to Buy?

If you stay in a hot and tropical climate, you would use an air conditioner more often. In that case, buy a 5-star AC as it would cool the room faster and keep the bills down. 

However, if you live in a cooler place and just need the AC during the warmer season, then you can consider a 3-star AC. It would be a cheaper option and it works best in a less humid climate.

If you don’t want to consider the location, go for a 5-star AC as it outranks 3-star AC in many aspects. 

When and Where to Buy

One of the best times to buy an AC is during the festive season when there are a lot of sales or during the off-season when the prices are low.

You can buy an AC on EMI online on different platforms like Amazon, Flipkart, etc. If you need finance to buy the AC, you can use MoneyTap’s ShopOnTap option to shop on your favourite eCommerce site and pay the amount in EMIs. 

Consider all your options and make an informed decision about which AC would be a better choice for you.
