The summer season in India is not just a season; It brings chaos, body irritation, and full blown discomfort that makes daily life difficult. Thanks to air conditioners, that' saving our lives. However, buying an AC in India is not just about cooling, it is also about electricity bills, daily usage, and long-term cost. One of the biggest confusion that people face while buying an AC is which star to choose. The confusion between 3 star and 5 star AC's is a big one and the price difference is also noticeable.

At first glance, the 3 star AC looks like a better deal, but the real answer is hidden and depends on how you use it. I also witnessed same confusion when I decided to buy an air conditioner for my home. To make things easy for my reader, my today's article will explain the difference in simple terms so you can decide what works best for you.

What is the Real Meaning of Star Rating in AC

Many of you might not know what is the real meaning of 3 star and 5 star rating in AC. The star rating in AC showcases how energy efficient it is. A 5 star AC will always consume less electricity as compared to a 3 star AC for the same cooling output. These ratings are given by the Bureau of Energy Efficiency in India.

To understand this in simple words, the higher ratings mean less power consumption and low rating means high consumption. However, higher rating also mean upfront price, too, so choose according to your budget and needs.

3 Star vs 5 Star AC: Price Difference

In most of the cases, a 5star AC would costs between Rs 40,000 to Rs 70,000. The price varies and depends on the brand and features. Whereas, the 3 star rating AC is priced between Rs 30,000 to Rs 50,000. For many Indian household, this price difference matters, especially when they have to invest in multiple AC units at the same time.

This is the main reason, people often question themselves if the extra cost will actually save money later o not.

The Electricity Bill Difference Plays an Important Role

This is the main point where all the real difference comes in. A 5 star AC can save around 15% to 25% electricity bill as compared to a 3 star AC.

To understand this, let's assume you use your AC for 8-10 hours a day during peak summer season. Then, your electricity bill difference becomes noticeable. Over a full season, a 5 star AC can save a few thousand rupees. Nevertheless, if you are suing your AC only for 2-3 hours, then the savings will be very small. In such situations, the higher price of a 5 star AC may not feel worth it. So the decision factor will depend on how much AC you use and how much energy it consumes on daily basis.

Star Ratings vs Usage Patterns

In India, the usage pattern plays an essential role in deciding which AC to purchase. If you are living in cities like Delhi, Jaipur, or Lucknow, then your AC usage will be high as these cities have extreme summer. In these cities, a 5 star AC makes more sense as it reduceds long-term electricity cost.

At the same time, if you are living in cities with moderate weather or in homes where AC's are used occasionally, then a 3 star rating AC will work fine and usually enough.

Room Size and Installation Matters

This is not taken into consideration by many buyers, yet the size of a room and its insulation have an impact on cooling more than the star rating. Any incorrect tonnage AC will use up more power regardless of rating.

To illustrate, when a small AC is used in a big room, electricity consumption will be more. In the same manner, inadequate insulation, direct sunshine, or rooms located on the top floor can add pressure on the AC.

Thus even a 5 star AC might not be efficient when these factors are not taken care of.

Maintenance

The 3 star ACs as well as 5 star ACs should be serviced regularly. Filter cleaning, gas check, and proper installation all play a vital role in efficiency. Moreover, inverter AC technology is of greater significance today compared to star rating.

A good inverter 3 star AC may in practice sometimes do as well as a 5 star AC inverters.

Which One Should You Choose

This choice is determined by your usage. When you use a AC on a daily basis, long hours, then a 5 star AC will be a better investment. It will make money saving in the long run. When your usage is limited or seasonal a 3 star AC is good value without necessarily having to spend a lot of money on buying it.
