3-Star vs 5-Star, Dual Inverter AC: Which has lower electricity bill and which gives more cooling?

By the end of the month of March, the temperature of the sun starts rising and the desire for coolness instead of fan air increases in every house. In today’s time, air conditioner is not a unique thing but has become a necessity to get relief from the increasing heat. Especially in cities, it is now becoming almost impossible to spend summer without AC. However, while buying a new AC, along with happiness there is also a big worry in the mind, and that is the electricity bill.

How much will be the impact on the pocket every month after running the AC? Is 3-star AC better or 5-star? Many people get trapped in the maze of these questions. If you are also thinking of buying a 1.5 ton AC this year, then understanding this economic mathematics will prove beneficial for you.

Why is 1.5 ton AC popular?
At present, 1.5 ton AC is in highest demand in Indian homes. This AC is considered best in terms of cooling for medium sized bedrooms or halls. However, its electricity bill depends on its star rating. Let us understand the mathematics of 5-star AC.

An AC with a 5-star rating may seem a little expensive initially when purchased, but in the long run it saves money well. Power Consumption: The 5-Star 1.5 Ton Split AC consumes approximately 840 Watts (0.8 units) of power per hour. Daily consumption: If you run this AC for an average of 8 hours a day, it will consume 6.4 units of electricity per day. Monthly bill: If the electricity rate in your area is Rs 7.50 per unit, then the daily expense can be around Rs 48 and the monthly bill can come to around Rs 1,500.

3-Star AC: Cheap but electricity bill high? Many people find 3-star AC economical, but the mathematics of its power consumption is slightly different. Power Consumption: The 3-Star 1.5 Ton AC consumes approximately 1104 Watts (1.1 units) of power per hour. Daily expenditure: If this AC is operated for 8 hours daily, it consumes about 9 units of electricity. Monthly bill: Accordingly, the daily expenditure comes to around Rs 67.5 and the monthly electricity bill reaches around Rs 2,000.

In brief, by using a 5-star AC, you can directly save about Rs 500 every month compared to a 3-star AC.

What is dual inverter AC? Nowadays, ACs with dual inverter technology are also available in the market. These ACs increase or decrease the speed of the compressor according to the room temperature. This reduces electricity consumption and saves more in electricity bill. If your budget is a little higher, then buying a dual inverter AC can always prove to be a better option.

While buying an AC, do not only look at the price of the machine, but also pay attention to its star rating. By spending a little extra money initially and getting a 5-star AC, you can save thousands of rupees in electricity bills for many years to come.
