Thinking of buying an air conditioner?

Are you not sure of which AC will be the best for you to beat the heat? Hundreds of models of AC available in the market are confusing you? Are you thinking, whether a 3 star AC is better or a 5 star AC is better?

To understand the difference between 3-star and 5-star ac, we must first know how it works and some more basics as well.

What is the meaning of the star rating in air conditioners?

The star rating in any electrical appliance basically symbolizes the energy efficiency of the given appliance. In an air conditioner, the rating helps buyers understand the efficiency of the model. The ratings range from 1star - 5star.A higher rated product is a better product. More stars mean the model is more environment-friendly and will consume less electricity. A model with the better rating is built in a manner that it consumes lesser energy for the same level of cooling output.

The star rating convention is used worldwide to help ordinary people understand the difference between differently efficient ACs available in the market.

Let us understand STAR RATINGS better!


Star Rating System is a way of assessing its energy efficiency. In simple terms, the star rating of an AC reveals the electrical power required by the equipment to cool down the room. The star rating of an air conditioner takes two major factors into account:


  • BTU
  • EER


Star rating of an electrical appliance used for cooling (or heating) is determined by a ratio called the Energy Efficiency Ratio (EER) which is the ratio of cooling capacity of an AC in British Thermal Units (BTU) per hour, to the total electrical input.

The star rating is a standard rating of electrical appliances. The ratings mainly say that more the number of stars a model shows, more you will be able to save when you are using them. Now, all you need to know is the difference between 3-star and 5-star ac.

As the number of stars increases, the energy savings also increases. With each star, you are able to save 14% more. Quite necessarily, a 5-star air conditioner saves 28% more than 3-star AC.The ratings determine the exact savings of each electronic appliance specifically depending on the capacity of the appliance.


Major difference between 3-star and 5-star AC

  • The difference between 3-star and 5-star AC is its efficiency. Just as the 5-star portrays from its name, you will find it working with better efficiency compared to the other one.
  • The power consumption of a 5-star air conditioner is less.


Which one is better – 3-star or 5-star air conditioner?

If we are to choose between a 3-star air conditioner and a 5-star air conditioner, we need to keep the budget in mind.The actual cost and the operating cost of the two-star ratings vary. A 3-star Air conditioner is definitely cheaper than a 5-star Air conditioner. The operating cost of a 5-star Air conditioner is less than a 3-star Air conditioning system. 

As mentioned above, the 3-star air conditioner is a good budget buy for occasional use. A 5-star air conditioner is costlier but for a better choice for daily use. The flexibility of the stars help you realize what will suit you the best, so wisely take your decision.
