3 Star vs 5 Star AC Power Consumption: While buying an air conditioner (AC), most people first look at its price, but more important than that is its star rating.

3 Star vs 5 Star AC

3 Star vs 5 Star AC Power Consumption: With the daily heat rising, ACs are no longer just a luxury, but a necessity in many homes. Therefore, most people consider the price of an air conditioner (AC) first when purchasing it, but even more important is its star rating. This rating determines how much electricity your AC will consume and how much your monthly electricity bill will be.

With rising electricity prices in India, choosing an AC with the right star rating can result in significant savings in the long run. The biggest question then is whether it's better to buy a 3-star or a 5-star AC. So, let's explore how much electricity savings a 3-star and 5-star AC can offer per hour.

What does the star rating of 3 Star and 5 Star AC mean?

The star rating of air conditioners is decided by the Bureau of Energy Efficiency (BEE). This rating tells how well an AC provides cooling while consuming less electricity. A 5 Star AC provides better cooling with less electricity. It consumes approximately 10 to 28 percent less electricity than a 3 Star AC. A 3 Star AC is cheaper to buy, but its electricity cost may be higher if used for a long time. The star rating is decided on the basis of ISEER (Indian Seasonal Energy Efficiency Ratio). The higher the ISEER, the less electricity the AC will consume.

How much electricity is saved in a 3 Star and a 5 Star AC in 1 hour?

If you use a 1.5-ton AC, a 3-Star AC consumes approximately 1100 to 1200 watts of electricity per hour. A 5-Star AC, on the other hand, consumes approximately 800 to 900 watts per hour. Consequently, a 5-Star AC consumes approximately 15 to 25 percent less electricity than a 3-Star AC, which can result in significant savings on electricity bills in the long run.

Which is the best option between 3 Star and 5 Star AC?

Typically, a 5-star AC costs around 5,000 to 10,000 rupees more than a 3-star AC. If you use your AC for only 2 to 4 hours daily and are on a tight budget, a 3-star AC may be a good option. However, if you use your AC for 6 to 10 hours daily, want to keep your electricity bills low, and plan to use it for many years, a 5-star AC may be more beneficial.
