Complete Buying Guide for best ac for low electricity consumption

Complete Buying Guide for best ac for low electricity consumption
Buying Guide for best low electricity consumption AC

AC comes at a high price but ac is not something that we change every year like mobile. So When you are planning to buy the best energy-saving air conditioners then there are a few things you have to keep in mind.

Cooling Capacity with Room SIze 

The first thing that comes in our mind when we are going to buy an air conditioner is how much cooling capacity of AC we Should take.

Because  if you are not able to choose the right capacity of  air conditioners it may cause less cooling or high electricity consumption.

So choosing the right capacity of air conditioner is very Important according to your room size.

The basic rule you have to follow for an air conditioner that is Higher Ton ,means  the greater the cooling capacity. That means it can cool the large room quickly.

So we have brought some rough idea regarding the air conditioners:-

Room Size(Sq Ft.)Required Ton
100 Sq Ft.0.9 Ton
150 Sq Ft.1 to 1.2 Ton
200 Sq Ft.1.2 to 1.5 Ton
250 Sq Ft.1.2 to 1.5 Ton
300 Sq Ft.2 to 2.3 Ton
400 Sq Ft.2.5 to 3 Ton
Accurate Cooling capacity with their room size to find best AC for low power consumption

But you can not only depend on this table but you also have to keep some other things in mind:-

  • If your room is getting direct sunlight from three sides then you have to choose the Higher Tonnage.
  • If your room ceiling is higher than the normal then also go with more Tonnage.
  • If your room has lots of glass then also you have to go higher.
  • We have calculated these numbers according to 3 to 4 members so if you want AC for less than 3 members  then go with Lower ton but if you need AC for more than 4 members then go with a little higher ton.
  • If you live in those areas where your room does not get direct sunlight then go with little lower Tonnage.

Energy Star Rating

When you are going to buy an air conditioner then this Energy Star rating plays a vital role to find a good energy saver AC for you.

Generally BEE star rating is used to give a rating from 1 star to 5 star, according to their electricity consumption. 

1 stat is the lowest star rating which shows that these electrical devices consume lots of energy compared with 2,3,4 and 5 star and 5 star is the highest star rating which shows that these electrical devices consume less energy compared with 4,3,2 and 1 Star rating.

So I always suggest that you should always go with a 5 star rating which can help you to save your electricity bill.

ISEER

ISEER stands for Indian Seasonal Energy Efficiency Ratio 

In earlier times, EER(Energy Efficiency Ratio) was used to communicate energy efficiency in India. But this was less Accurate.

Therefore India’s Bureau of Energy Efficiency came up with a new idea and which is ISEER which is more accurate than EER.

Always check the ISEER. Higher ISSER rating will provide cooling with low power consumption. And we suggest that go with above 4.5 value which will give you great performance.

Inverter AC or Non-Inverter AC

This also a super confusing question comes in our mind when we are planning to buy an AC that we should go with Inverter or Non-Inverter so in this topic I will try my best to solve your doubt regarding this.

The main difference between the Inverter or Non Inverter AC is the compressor. 

Non-Inverter AC generally works on, on  off principle that means when we set a temperature on AC then the compressor of this AC turns on and runs with the same speed until it reaches  the set temp.

And then it automatically turns off the compressor and when the temperature sensor senses that the room temperature goes down then again the compressor turns on until it reaches to set temperature and then again turns off. And the same process goes on and on.

But the Inverter AC’s compressor is designed in a way that it can run with a variable speed so that it consumes less energy. 

Because of the On and Off process Non-Inverter AC consumes lots of energy comparison with Inverter AC. 

But one thing you should keep in mind is that If you want to operate AC for 3 to 4 hours a day then you should go with Non-Inverter AC because Non inverter AC comes with very less price and 3 to 4 hours a day does not make a huge difference.

But If you want to operate AC for more than 5 hours then definitely you should go with Non-Inverter AC. It will help you to save some bills.

Dual Inverter AC or Normal Inverter AC

Dual inverter AC is a technology where the compressor contains dual rotor so that it can provide fast cooling and works more efficiently and also consumes less power. So if available then always go with Dual Inverter AC.

Aluminium Coil or Copper Coil

If we have to know the difference between copper coil and Aluminium coil:-

Aluminum Coil

  • Cheaper than copper coil
  • More Flexible.
  • Less Durable than copper
  • Not Corrosive Resistant
  • Slow Heat transfer cause slow cooling
  • High Maintenance.
  • High energy consumption.

Copper Coil

  • Cheaper than copper coil
  • More Flexible.
  • Less Durable than copper
  • Not Corrosive Resistant
  • Slow Heat transfer cause slow cooling
  • High Maintenance.
  • High energy consumption.

So the conclusion is you should always go with a copper coil.

Refrigerant

Refrigerants are the most important part of the AC. Because this is the thing which cools the room air and refrigerant is also known as Coolant.

There are plenty of refrigerants used in AC like R 401 A, R 32, R 22, R 134 A etc. 

But from all these R 32 is the latest one which is now used on the new model AC. And also this is the best  refrigerant from all these because it doesn’t harm the atmosphere and it is more energy efficient than others.

So the final answer is you should always go with R 32 refrigerant which is always the best.

Noise Level

Generally AC produces lots of noise. So if you don’t want to be distured by constant sound produced by your air conditioners then you should always go with less Noise level AC.

Always consider your AC produces less than 45 dB of noise level.

Brands After Sale Service

Before buying an AC you have to check which AC brand gives a good after-sales service in your area otherwise, if there is a defect in AC then you can’t take advantage of the warranty for AC so you should always check the brand’s after-sales service.

Warranty

Generally, it’s easy to fix the problems of AC’s but sometimes the AC might get into huge problems and completely stop working. It doesn’t happen often but it might happen. So make sure the Warranty of your AC. 

Nowadays almost all the AC’s come with 1 year of product warranty, and 5 to 10 years on compressor warranty. 

Additional Features

Nowadays ACs come with extra features and all these features should also be taken care of when you are going to buy an AC:- 

Air Filter

Nowadays almost all the ACs come with an air filter function which works as an air purifier so if you live in a polluted area then you should definitely look at this feature in your AC. It  will give you healthy and fresh air throughout the room. 

Dehumidifier

If you live in a coastal area then this function is very necessary for you to maintain the humidity of your room. So that you don’t have to buy a separate humidifier for yourself. You can also use this function during the monsoon season to maintain humidity.

Stabilizer

Nowadays most of the ACs come with inbuilt stabilizer. So if you do not want to buy a separe stabilizer then you should go with this function.


Frequently Asked Questions (FAQs) of Most Energy Efficient Air Conditioners

Which AC has low power consumption?

Generally 5 star Dual Inverter AC’s come with low power consumption. Because 5 star Non-Inverter AC consumes 40% more power than Inverter AC.

Can I run my AC 24*7?

If you run your AC 24*7 then it consumes lots of energy and it can also deteriorate quickly. According to my opinion you should not run any electrical device 24*7. Because the machine also wants some rest.

Which brand AC is best?

There are plenty of brands available in the AC manufacturing market. And almost all the brands are providing good service to the customer. If I name some of the best brands then LG, Panasonic, Godrej, Voltas, Blue Star, Sanyo, and Daikin are some good names.

Which AC consumes less electricity window or split?

It’s unfair to compare Window AC with Split AC because those have their own features and mainly window AC comes with lower price and Split AC comes with a higher price. 

But in terms of Power Consumption because maximum Split AC comes with inverter technology so split AC consumes less power.
