Best AC in India 2020 – Buyer’s Guide

Working of the air conditioner?

Air conditioners give you much needed thermal comfort during scorching summer more specifically AC helps to maintain the room temperature at the optimum level they also help remove airborne particles and humidity from the room. Let’s find out how this cooling machine works.

Let’s start with a very simple approach to understanding the functioning of an air conditioner,

An air conditioner has two connected coils with continuously flowing refrigerant fluid inside them the coil inside the room is called the evaporator and the coil outside the room is called the condenser. The fundamental principle of an air conditioner is simple, just keep evaporator cold more specifically colder than the room temperature and the condenser hot more specifically hotter than the surroundings with these conditions the continuously flowing fluid will obviously absorb heat from the room and eject it out to the surroundings this is the fundamental rule of an air conditioner.


To achieve this objective two more components are needed in your air conditioner a compressor and an expansion valve, the compressor will increase the pressure of the refrigerant. The compressor handles its refrigerant and its gaseous state so that when it compresses gas the temperature rises along with the pressure. The temperature at the compressor outlet will be far higher at atmospheric temperature. Therefore when this hot gas passes through the condenser heat exchanger then heat can easily get ejected, a fan in the condenser unit makes this task easier. During this phase, the gas transformed into a fluid.


The condenser has an expansion valve mounted at the exit end to restrict the refrigerant flow hence reducing the pressure of the fluid. As the pressure drops one part of the refrigerant liquid is evaporated this results in a refrigerant temperature drop. This low temperature should be at the temperature lower than the room temperature so bypassing the room temperature over the evaporated coil the room temperature drops. The refrigerant gets converted to vapour during this heat absorption process.

Hence we have fulfilled the rule of an AC, that temperature inside the room is lower than the temperature outside the temperature.

How to select the proper size AC unit?

When it comes to the room size it is important to choose the air conditioner which is suitable for your room size. If you choose an air conditioner whose cooling capacity is beyond your room size then it is going to shut off early and not have enough time to dehumidify and remove the necessary moisture, Leaving with you with the very cold and clammy environment and on the other side the air conditioner is too small for the environment that you are cooling then the air conditioner will continuously run and it will never cool the room properly, never dehumidify the room properly and costing you more in energy.

So how do you find the proper size air conditioner for your room?

The Scientific way to find out perfect ac for your room is,

  1. Measure the square footage of the room (length*width)
  2. If the room is on the main floor then, (Square Footage * 30)
  3. If it’s a second floor or kitchen area then, (Square Footage * 40)
  4. Ceiling height is over 8 feet then add 1000 BTU for every foot over that 8 feet.
  5. No. of people living in the room should also be taken into consideration, for each person over the first two individuals you should add an additional 600 BTU in it.

Remember 1 Ton = 12000 BTU

Note – This is not the only calculation for calculating the BTU. there are many other calculations available on the internet.

What is the concept of the tonnage of the AC?

The ability of AC to remove the heat from a room in one hour is known as Tonnage capacity of AC. mathematically it is represented as BTU (British Thermal Units). 1 ton equals 12000 BTU. Hence when the BTU is higher then there is a better cooling effect.

Electricity consumption of the AC units:

How much electricity does an AC unit consume? This is the normal question every buyer asks the seller. There are many factors which affect the electricity consumption an AC unit like, star rating of AC unit, tonnage capacity, whether it is inverter AC or Non-inverter AC, usage of the AC, modes of operation of AC, climate conditions, maintenance of AC unit is also the main factor etc. this is the factors that affect the electricity consumption of an AC unit. 

Modes of operation of the AC units:

AC unit can be used in various modes available in it, some of them are explained below.

Best AC in India - AC Modes

Cool Mode:

This is the default mode available in any AC even in coolers also. The fan speed and temperature setting are responsible for this mode. Ideally, the temperature should be 25-degree centigrade to get the maximum efficiency.

Fan Mode:

You can save energy by using this operating mode by keeping compressor out of work and only fan in work but this does not make it in cooling of a room, a ceiling fan can do a better job than this.

Dry Mode:

If you are using AC in near sea area then this is the ideal model to use as it removes humidity from the air which results in cooling of the room automatically. In this mode, the fan runs at a lower speed and the compressor for a shorter period of time in larger cycles.

Energy Power Saver Mode:

AC’s have become smarter day by day, This AC’s has Energy Power Saver Mode in which it shuts down the compressor when the temperature of the air reaches the level set in the thermostat. While the fan keeps running to maintain the coolness. When the temperature exceeds a certain level, the compressor starts functioning again and we all know that the compressor is the largest consumer of electricity in any electronic appliance.    

Quick Cool Mode:

Frankly speaking this not an energy-saving option but many of AC’s have this option in which AC starts working at a lower temperature of 16 or 18-degree centigrade which results in energy consumption as the compressor has to do a lot of work in less amount of time. The only advantage of this feature is that it cools the room in less amount of time as compared to other modes.

Sleep Mode:

This is a special mode in which temperature increases by 1 degree/hour until the temperature by 2 degrees. As the exterior is already cooler in night hence this mode is mostly used in the night time. Hence it is on your fingertips to save electricity. 

Inverter AC vs Non-Inverter AC:

Now we are going to see the main difference between the Inverter AC and Non-Inverter AC which will show you the pros and cons of both the type of ACs.

Non-Inverter AC Inverter AC
OperationCompressor runs at a fixed speed. Compressor runs at a variable speed.
Energy Consumption Consumes more energy. Consumes less energy
NoiseIt makes more noise It makes less noise
Compressor auto shut down The compressor gets switched on/off frequently Compressor runs all the time frequently
Electricity bill Energy consumption is the high Consumption is 30% to 50% less
CoolingUneven cooling Uniform cooling
ComfortLow ComfortHigh Comfort
Compressor EfficiencyLessHigh
Ozone Friendly It uses R22(HCFC) which is not ozone friendly Most of inverter AC use R32 or R410A which are ozone friendly
Life SpanDoesn’t last longerLasts longer time
CostCheaper than Inverter ACExpensive than Non-Inverter AC but it is long term investment which will result in saving money later.

Copper coil vs aluminium coil

We have seen the difference between the inverter AC and Non-Inverter AC now we are going to see the difference between the coils used in that ACs. hence you will get a brief knowledge of coils.

Copper CoilAluminium Coil
Heat TransferCopper has a high heat transfer coefficient. Aluminium has a low heat transfer coefficient.
Cost FactorIt is expensive than aluminium coils but it saves lots of money in future. It is cheaper than the copper coil and not for long term use.
MalleabilityIt is less malleable. It is highly malleable.
StrengthCopper coils are undoubtedly stronger than Aluminium coil. These coils don’t last for a longer time.
MaintainanceCopper coils are easier to maintain. Aluminium Coils are difficult to maintain.

Reciprocating compressors vs rotary compressor :

Till now you have seen the major factors of Inverter AC /Non-Inverter AC and Copper coil/Aluminium coil but now we are going to understand about the main component of AC “Compressor”.

So, what is a compressor?

Anyone will say the compressor is the key part of AC.in fact it is the soul of AC, hence you must have the proper knowledge of working of a compressor.

Now the question comes, what is compressor?

It is responsible for pressing the AC system and keeping the coolant flowing so that it can work properly. The compressor is the ‘heart’ of the air conditioning system, moving the refrigerant through the system.

There are two types of Compressors are used in AC

1. Reciprocating Compressor:

A reciprocating compressor consists of a piston move downwards reducing pressure in its cylinder. When the cylinder goes down it brings the gas in and When the cylinder goes up then it increases pressure to force the gas back out. The up and down motion is called reciprocating motion. Due to this, it is known as a reciprocating compressor.

Best AC in India - Working of Reciprocating Compressor
  • Designed for small sites such as home.

  • Easy for maintenance.

  • Not for continuous use.

  • Makes lots of noise.

2. Rotary Compressor:

The compressor uses two helical types of rotors that rotate and move the air from the compressor’s intake towards the end of the screw and the outtake. As the air moves from one end to another then space gets increasingly smaller thus compressing the refrigerant.

Best AC in India - Working of Rotary Compressor
  • Less noise and vibration.

  • Best for large scale air conditioning operations.

  • Have to be used continuously.

  • Expensive.

Star Ratings, EER:

Star ratings:

Whenever you buy an AC first thing you should notice is the star rating of the AC.but what is star ratings? It is the rating given in the form of stars, in which 1 mean low efficient and 5 means high efficient, given by The Bureau of Energy Efficiency, Department of Energy Savings, Government of India prescribing star ratings for various electronic products.

These star ratings are fixed for a specific period. 

Best AC in India - BEE Star ratings

Energy Efficiency Ratio:

EER is a very important aspect while purchasing the AC. Scientifically, it is the ratio of an amount of heat removed from the room in one hour to the power consumed by AC compressor in one hour.

Hence the ACs with higher EER will give you better performance and are more efficient as they remove more heat per hour per unit of power consumed.
