Why You Should Not Buy a 5 Star AC

People wonder which is better, a 5-star or a 3-star air conditioner, and they sometimes compare 3 Star Vs 5 Star AC and doubt, What is the difference between a 3-star AC and a 5-star AC? So, in this section, we will discuss the advantages of both types of air conditioning machines, their efficiency, and what to install in your home.

First of all, let’s compare the 3-Star AC with the 5-Star AC (3-star AC vs 5 Star AC)

Both the AC (3-star rating or 5-star rating) are energy-efficient units. They outperform a 1 or 2-star AC, but the 5-star model has the highest ISEER energy efficiency rating. The star indicates that it is more efficient in cooling and saves energy. Let’s take a look at some comparisons.

Ac Power Consumption (Watts) in per Hour

Note: This data is taken from various official sites, and it may vary as per the usage, but while using an AC for standard time, the AC will consume as per the above data.

Most people prefer higher ratings to lower ratings, but is it worth buying a 5-star AC unit over a 3-star AC? Let’s figure it out!

The company claims a 5-star air conditioner is 28% more energy efficient than a 3-star air conditioner. But is it truly a game changer?

In a nutshell, no when purchasing a 5-star AC that costs at least 5000–8000 rupees more than a 3-star AC.

When you compare the power consumption of a 3-star AC to that of a 5-star AC over a year, you will notice that the difference is only about Rs 500. It means you can buy 3 stars, not 5 stars. Let’s see how it works.

Is a 5-star AC worth it?

Live in a humid coastal area, such as Kolkata, Mumbai, Goa, or any other coastal area, and you don’t use an air conditioner frequently. A 3-star air conditioner may be a better choice.

Furthermore, if you are on a tight budget or cannot afford a high-end AC unit, the 3-star air conditioner will be ideal. Because less use of an AC already saves money on the bill, why pay more for a 5-star AC?

If you live in an extremely hot climate where the air conditioner will be used for more than 12 hours daily, investing in a 5-star air conditioner is best. This could help you save much money on your electricity bills in the long run.

A report from the Center for Science and the Environment says that when the temperature outside is 40 degrees Celsius, 5-star AC units work the same as 2-star AC units. Because of the increased power consumption, the AC must use more power to cool the room, resulting in high loads that consume more electricity. Similarly, if you set your air conditioner’s temperature below 27 degrees, its power consumption will increase, reducing energy efficiency even further. We must write this article and cite this report to make you a wise buyer.


Why Do You Buy a 5-Star?

  1. Buy 5 stars when its usage is over 12 hours (15–22 hours daily).
  2. If you don’t have budget issues, buy a 5-star AC.
  3. If you want feature-rich AC, then buy a 5-star AC.

Why Do You Buy a 3-Star AC

  1. If your usage is moderate or you use daily below 8 hours.
  2. If you need AC for humid conditions, then buy a 3-star AC.
  3. If you are budget constrained, then buy a 3-star AC.

YES, because a 5-star air conditioner will cool your room most efficiently and faster, you can buy a 5-star AC.

What are the cons of 5-star AC?

It is expensive and performs similarly to a 3-star if the outside temperature is around 40 degrees Celsius or if you use it at the set limit of 27.

Is it worth spending on a 5-star split AC over a 4-star one regarding the power bill?

Yes, if you use the AC for a long time, such as more than 20 hours per day and 8 to 10 months per year, purchasing a 5-star Split AC over a 4-star AC is worthwhile. If you use it for a shorter period, go for a 4 or 3-star rating.

Which is better 4, star or 5-star inverter AC?

Regarding efficiency, a 5-star inverter AC is better than a 4-star AC.
