In summer, the electricity bill of a 1.5 ton AC can be heavy on your pocket, but if you make the right choice while buying an AC, then the summer will not be heavy on your pocket. Generally people do not understand the difference in power consumption and expense between 3 star and 5 star AC. Shopkeepers also try to sell those products to the customers by saying anything in which they see more profit. But as a customer, you should know all the things beforehand, so that your decision is based on your knowledge and not on the mischief of any shopkeeper. So let us tell you how much electricity 3 star and 5 star ACs consume.
As the heat of summer increases, air conditioners start running in all our homes. Those who do not have ACs in their homes also start thinking about buying a new AC. In the midst of extreme heat, if you get the cool and soothing air of AC, then the feeling is different. But one tension always remains – the electricity bill. When people go to buy a new AC, they are stuck in the showroom standing in the showroom wondering whether they want to buy a 1.5 ton AC but should they buy 3 star or 5 star? Is it really wise to pay a few thousand extra rupees to get 5 stars or is it just a marketing ploy? If you are also planning to run an AC or buy a new one this month, then wait and understand this mathematics a little deeper, because this small decision can affect your pocket.
The easiest way to understand the power consumption of an AC is to look at its rating and wattage, which experts also call ISEER rating. In simple language, the higher the rating, the less power your machine will consume. A typical 5 star rated 1.5 ton AC has a wattage of around 1,500 to 1,600, which means it consumes around 1.5 units of electricity in an hour. Whereas if you look at a 3 star AC, its wattage is around 1,700 to 1,800, which consumes about 1.75 units every hour. At first glance this difference of 0.25 units seems very minor, but the real game starts when the AC keeps running for hours. And the AC runs for at least 10 hours or even more.
Let us now weigh this difference in rupees, so that the matter becomes completely clear. Suppose your AC runs for 12 hours daily during the summer season. According to this, a 5 star AC will consume 18 units of electricity in a day and about 540 units of electricity in a whole month. If we also assume the average rate of electricity to be Rs 8 per unit, then your monthly expenditure comes to approximately Rs 4,320. This is the price you pay every month for your comfort, but in the case of 3 star ACs the story becomes a little expensive.

If the same 12 hours is spent with a 3 star AC, it will draw 21 units of electricity daily, taking the monthly figure to 630 units. At the rate of Rs 8 per unit, its monthly bill will be Rs 5,040. This simply means that you are paying Rs 720 more every month for running a 3 star AC. Even if you run the AC only for 7 months of the year, then a 3 star AC puts an extra burden of about Rs 5,040 on your budget, which is a huge amount.
To control the electricity bill, the rating of the machine alone is not enough, but the way you operate it also matters a lot. The most solid mantra to save electricity is to run the AC between 24 to 26 degrees Celsius. Experts believe that you can save about 6 percent electricity by increasing the temperature by every one degree. Apart from this, it is also important for the sealing of the room and the windows and doors to be air-tight, so that cold air does not come out and there is not too much pressure on the compressor.
To keep the life of AC long and to keep the bill under control, it is very important to get it serviced on time. Due to dirty filters and old gas, the AC has to work harder to cool the room, which increases electricity consumption. Often people waste thousands of rupees in electricity bills in order to save money on servicing. Therefore, it is always beneficial to get a professional checkup done once before the season starts so that the AC runs smoothly and does not become heavy on the pocket.
When you go to buy AC in the market, you will find that the price of 5 star AC can be higher by about Rs 5,000 to Rs 10,000 compared to 3 star. Initially this may seem like an expensive deal, but if you calculate the next 5-7 years, then this extra money is recovered within just one or two years through electricity savings.
In today’s time, inverter AC is considered the smartest choice, because it increases or decreases its speed according to the temperature of the room. If your usage is more than 8-10 hours a day, then it makes sense to go for a 5 star inverter AC. This will not only give you relief from the scorching heat, but will also prevent you from getting shocked by the electricity bill at the end of the month. (Image – AI)
