What is the Difference Between a 3 Star AC and 5 Stars AC?

A 3 star AC or a 5-star AC-which one to buy?

If you have ever been into this dilemma, this blog is exclusively for you!

Air conditioners with 5 star ratings are often preferred over ACs with low ratings. The reason can be power consumption, maintenance cost and more. Besides, 5 star or higher rating ACs are chosen because of their efficiency to cool the inside of the room or hall, way faster than other ACs with low ratings.

So, if you are in the quest to figure out whether to buy a 3 star AC or 5 star AC, continue reading the blog to know answers to all the possible questions related to ACs.

But before that, let us begin with an understanding of what a star rating AC is. Once done, we will take you through which star rating AC is good to buy, factors that affect the AC power consumption, ways to reduce AC power consumption and more.

An Overview of Star Rating ACs

A star rating appliance or AC showcases its energy efficiency. The more the number of stars, the more will be the appliance’s energy efficiency. Generally, the star rating starts from 1 and ends at 5. More stars labelled on an AC depict its energy efficiency and hence, are more likely chosen by people.

Difference between 5 Star AC and 3 Star AC

The following points elaborate the differences between a 5 star AC and a 3 star AC-

  • Cooling and power efficiency in a 5 star AC is higher than the AC with 3 stars
  • 5 stars AC consumes less energy as compared to 3 stars ACs; hence, lets a user save money on electricity bills
  • ACs with 5 stars have a better build than those with 3 stars
  • Usually, 5-star ACs have a bigger condenser when comparing it with 3 star AC, which eventually results in better heat exchange
  • 5 star ACs produce less heat than 3 stars ACs
  • ACs with 5-star ratings can be used round the year
  • ACs with higher ratings are considered powerful as they cool the room faster

Power Consumption between 3 Stars ACs and 5 Stars ACs

Based on the weight of the ACs, the following are the differences that made 3-star ACs and 5-star ACs different from each other-

Star rating0.75 ton1.0 ton1.5 ton2.0 ton
3 star rating542 watts747 watts1104 watts1448 watts
5 star rating450 watts554 watts840 watts1113 watts

What are the Factors that Affect AC Power Consumption?

There are numerous factors that affect the AC power consumption, a few among them are written below-

  • Number of people in a room affects the AC power consumption. For example- a room of 20-25 people requires multiple ACs, whereas a room with 3-5 people requires a single AC to cool the room
  • Total number of electrical appliances inside the room generate more heat, which eventually increases the AC power consumption to cool the room
  • 5 star rated AC helps in saving energy, whereas, 1 star or 2 star AC demonstrates higher AC power consumption
  • The temperature outside and inside the room affects the AC electricity consumption. If the temperature outside is more than 35 degrees, the AC requires more electricity to cool the room
  • The choice of AC like window AC, Inverter AC, split AC, central AC affects the AC power consumption
  • The size of the room plays a major role when it comes to AC power consumption. The larger or bigger the room is, the more will be the AC power consumption. Similarly, smaller rooms do not consume higher AC electricity consumption

How to Calculate AC Power Consumption?

Listed below are a few important things to consider when calculating AC power consumption-

  • KW rating of the AC (it is available on the AC nameplate)
  • The AC’s daily total running hours
  • The total cost of 1 unit of the electricity board (let’s consider Rs. 6 as the 1 unit cost of the electricity)

The formula to calculate AC power consumption is-

Units per month = kW of AC * Daily running hours * 30 or 31 (month)

Now, let us calculate the AC power consumption by taking an example.

For example- There is a branded AC with 1.5 kW that runs for 8 hours a day.

So, the total power consumption of that AC will be, 1.5 * 8* 30 =360 units per month

Next, to calculate the electricity bill consumed by AC in a month, let us assume Rs. 6 as the per-unit cost of the electricity. Hence, the electricity bill in a month will be,

The electricity bill for AC in a month= Units per month * Cost of one unit

= 360 units * Rs. 6

= Rs. 2160

How to Reduce AC Power Consumption?

If you are worried about high AC bills every month, following are some of the tips or tricks to reduce AC power consumption-

  • Switch off the AC when it is not in use
  • Keep the AC temperature ideal
  • Ensure to opt for post-maintenance services
  • Change your AC as soon as you realize it is utilizing more energy
  • Sell, buy or exchange your AC if it is old
  • Run the ceiling run if you want to cool the room a little faster
  • Opt for IoT device as the device helps in switching off/on the appliances when in use or not in use
  • Close door and windows to cool the room fast
  • Clean the AC filters timely
  • Make sure that your AC does not receive direct sunlight. Keep the AC compressor in shade

Things to take care of before buying an AC?

Users should consider a few number of things before buying an AC

  • AC ratings
  • Type of AC
  • Maintenance cost
  • AC with their weight
  • ACs cooling capacity
  • Power consumption of AC

*Make sure to compare the number of brands, the services they offer, etc before buying an AC
