Air conditioners are a common appliance in most homes, especially in countries with hot and humid climates. They are essential for maintaining a comfortable temperature inside the house and provide relief from the scorching heat outside. When it comes to buying an air conditioner, one of the most crucial factors to consider is the energy efficiency rating. In India, ACs come in two energy efficiency ratings – 3 Star and 5 Star. In this article, we will discuss the difference between 3 Star and 5 Star AC.
3 Star vs 5 Star AC: What’s the Difference?

Energy Efficiency Rating
Before diving into the differences between 3 Star and 5 Star ACs, it is essential to understand what the energy efficiency rating means. The energy efficiency rating of an air conditioner is determined by the Bureau of Energy Efficiency (BEE), which is a government agency responsible for promoting energy conservation and efficiency. The rating is based on the amount of electricity consumed by the AC to cool a room to a specific temperature. The rating ranges from 1 Star to 5 Stars, with 5 Star ACs being the most energy-efficient.
When it comes to purchasing an air conditioner, one of the most important factors to consider is its energy efficiency rating. In India, air conditioners are rated on a scale of 1 to 5 stars, with 5 being the most efficient. The Bureau of Energy Efficiency (BEE) has mandated that all air conditioners sold in India must have a minimum energy efficiency rating of 3 stars. This means that any AC with a rating below 3 stars cannot be sold in India.
Difference between 3 Star and 5 Star AC
The difference between a 3 star and 5 star AC lies in their energy efficiency. A 5 star AC is more energy-efficient than a 3 star AC, which means that it consumes less electricity and helps to reduce your electricity bills. Let’s take a closer look at the differences between these two ratings.
Energy Efficiency
The main difference between a 3 star and 5 star AC is their energy efficiency. A 5 star AC is more energy-efficient than a 3 star AC. This means that it consumes less electricity to cool the same amount of space, resulting in lower electricity bills. For example, a 5 star AC may consume 20% less electricity than a 3 star AC for the same amount of cooling.

Initial Cost
The initial cost of a 5 star AC is generally higher than that of a 3 star AC. This is because 5 star ACs come with advanced features and technology that make them more energy-efficient. However, the higher initial cost of a 5 star AC is offset by its lower operating costs over the long run.
Environmental Impact
A 5 star AC is more environmentally friendly than a 3 star AC. This is because it consumes less electricity to cool the same amount of space, which means that it emits fewer greenhouse gases. In addition, a 5 star AC is made with more energy-efficient components, which means that it has a lower carbon footprint than a 3 star AC.
Long-term Savings
Although a 5 star AC may have a higher initial cost than a 3 star AC, it can save you money in the long run. A more energy-efficient AC will consume less electricity, resulting in lower electricity bills. Over time, the savings on electricity bills will more than offset the higher initial cost of a 5 star AC.
Cooling Performance
The cooling performance of a 3 star and 5 star AC is generally the same. Both ACs are designed to cool a given space, and they will do so equally well. However, a 5 star AC may have additional features that can help to enhance its cooling performance, such as inverter technology, which can adjust the cooling capacity of the AC based on the temperature of the room.
Differences in Tabular form
Here is a table summarizing the main differences between 3-star and 5-star ACs:
| Criteria | 3-Star AC | 5-Star AC |
|---|---|---|
| Energy Efficiency Ratio (EER) | EER≥3.3 | EER≥3.5 |
| Annual Energy Consumption | Higher than 5-Star AC | Lower than 3-Star AC |
| Cooling Capacity | Same as 5-Star AC | Same as 3-Star AC |
| Price | Cheaper than 5-Star AC | More expensive than 3-Star AC |
| Electricity Bill | Higher than 5-Star AC | Lower than 3-Star AC |
| Environmental Impact | Higher greenhouse gas emissions | Lower greenhouse gas emissions |
| Government Rebates | Eligible for Rebates | More Eligible for Rebates |
In summary, 5-star ACs are more energy-efficient than 3-star ACs and consume less electricity, resulting in lower electricity bills. They also have a lower environmental impact due to reduced greenhouse gas emissions. However, 5-star ACs are more expensive than 3-star ACs, and the initial investment may not be feasible for everyone. Additionally, 3-star ACs are eligible for government rebates, but 5-star ACs are more eligible for rebates. Ultimately, the decision between a 3-star and a 5-star AC depends on your budget and your preference for environmental sustainability.
Conclusion
When it comes to choosing between a 3 Star and 5 Star AC, it ultimately comes down to your budget and cooling requirements. If you have a large room and need a higher cooling capacity, a 5 Star AC may be a better option. However, if your budget is limited and you don’t need a higher cooling capacity, a 3 Star AC may be a more affordable option. Regardless of your choice, it is essential to buy an AC with an energy efficiency rating to save money on your electricity bills and reduce your environmental impact.
