Summer is here, and with it comes the scorching heat that makes you want to crawl inside your freezer. Well, another way to beat the heat is to invest in a brand-new air conditioner for your place. But the thing is, there are so many options available in the market from dozens of brands. And that’s not it, the energy efficiency ratings of these appliances also make it a little overwhelming to decide which one is worth buying as per your needs and budget. Usually, people get confused when choosing between a 3-Star and 5-Star AC. But fear not, my sweaty friend! In this article, we’ll break down the differences between 3-Star and 5-Star ACs and help you make an informed decision. We’ll even throw in a nifty table to help you calculate the power consumption and estimated electricity bills of both types of ACs. So let’s get going.
Understanding AC EER Ratings
The Bureau of Energy Efficiency (BEE) gives air conditioners a rating on a scale of 1 to 5, with 5-Star being the most energy-efficient and 1-Star being the least. In simple terms, the more stars an AC has, the more energy-efficient it is, which translates to lower power consumption.
To determine an AC’s energy efficiency, the BEE looks at two things: the cooling capacity and the power consumption. The cooling capacity refers to how much heat the AC can remove from a room in a given time, while power consumption is the amount of energy it uses to do so. By combining these measurements, the BEE calculates the energy efficiency ratio (EER) of the AC, which then decides the star rating it receives. So, in essence, when you’re looking to buy an AC, the number of stars it has is an indication of how much energy it uses, which can help you save money and energy in the long run.
Energy Efficiency and Power Consumption
Now, let’s talk about the difference between a 3-Star and 5-Star AC. Our handy table below shows the estimated power consumption and electricity bills for both options. While the initial cost of a 5-Star AC may be higher, the energy savings, in the long run, can really add up. Plus, by choosing an energy-efficient appliance, you’ll be doing your part to reduce your carbon footprint and help the environment.
| AC Rating | Cooling Capacity (Ton) | EER | Power Consumption (Units/Hour) | Monthly Power Consumption (10h/Day) |
| 3-Star | 1.5 | 3.5 | 1.2 | 360 |
| 5-Star | 1.5 | 4.5 | 0.89 unit | 267 |
Keep in mind that the data shown in the table above is related to Split air conditioners. So if you run your AC 10 hours a day for a month, a 3-star AC will definitely consume more units every month. And let’s do some calculations here. A 3-Star Split AC will consume around Rs. 2,214 (360×6.15) worth of electricity in a month and a 5-Star AC, on the other hand, will only consume Rs. 1,642 (267×6.15) in the entire month. Here we have simply multiplied the units consumed per month by Rs. 6.15 because that is the cost of 1 unit in most states of India.
Environmental Impact
When we think of air conditioners, we tend to focus on their ability to cool our homes and provide comfort during hot summer days. But did you know that the AC you choose can also have an impact on the environment? By opting for an energy-efficient 5-Star AC instead of a less efficient 3-Star AC, you can significantly reduce your carbon footprint and contribute to a more sustainable future.
Reducing your carbon footprint means that you are reducing the amount of greenhouse gas emissions produced by your home. This may not seem like a big deal, but when we all do our part, it can make a significant difference. So, if you’re looking for a way to make a positive impact on the environment while also saving money on your electricity bill, choosing an energy-efficient AC is a great place to start.
Of course, when it comes to choosing an AC, power consumption is not the only factor to consider. You’ll also need to think about the size of your room, the type of AC (window or split), noise level, and additional features such as air purification and humidity control. By considering your specific needs and preferences, you can make an informed decision that gives you the most value for your money.
Verdict
All in all, a 5-Star AC may cost a little higher up front, but believe it or not, it will be worth it in the long run. When you look at the power consumption of a 3-Star and 5-Star AC, there is a pretty noticeable difference. And that noticeable difference will be enough to make a hole in your wallet if you have two or three of 3-Star ACs versus the same number of 5-Star ACs at your home.
