Best AC In India – Buying Guide
Indian summer is really a hectic time to survive. At least like some hotter cities like Jaipur, Delhi, Agra, Nagpur, etc.
It becomes probably impossible to survive for the extremely scorching heat.
Moreover, for the increasing global warming effects, the temperature appears like hell pit in summer.
But, for the blessings of technology, we have air conditioners to save us from such tough situations in summer.
Presently, you can see there are a lot of air conditioner brands available in the market.
So, naturally, people have become more confused while purchasing the best AC.
Still, you have to consider several features of an Air Conditioner before investing your hard-earned money into it.
Here, in this article, we will provide you a complete AC buying guide that will be helpful for you while purchasing the best air conditioner for your home.
Before going further to the buying guide the basic thing you have to know is what an AC and how it works.
What is an Air Conditioner (AC)?
An air conditioner is a machine or system that treats air in a particular, usually surrounded area through a refrigeration cycle. In this way, the warm air is replaced and removed with the cooler air.
As per the construction, the entire system of heating, ventilation and air conditioning is known as HVAC (Heating, Ventilation and Air Conditioning).
So, before choosing the best AC in India, consider the type of Air Conditioner that you want to buy as per your convenience.
Types of Air Conditioners
There are mainly 3 types of ACs that you can see in the market, Split AC, Window AC and Portable AC.
Split Air Conditioner
As the name shows, this type of air conditioner comes with two units.
You need to install one unit mounted outside of the room on the wall and the other unit will be mounted inside the room.
In the outside unit, you can see a compressor and a condenser. The inside unit consists of a blower.
The compressor gets connected to the blower with a connecting pipe. The compressor draws air from outside and makes itself cool.
Then the air is passed to the blower and the blower throws the cold air into the room. In comparison with other air conditioners, split AC is more aesthetically pleasing.
These AC units are suitable for large bedrooms and large areas like commercial places.
Window Air Conditioner
Window AC comes with only one unit that has a combination of compressor and blower within it. This AC needs to be installed only in the window frames.
The blower present in the unit faces the inside walls of the room. And the other side faces the outside open air.

Portable Air Conditioner
In India, portable AC is very new. These air conditioners look like air coolers.
You can move this AC from one room to another room.
For portability, these AC units are known as Portable AC. This type of AC is suitable for those homes, particularly where you can’t mount a window AC or a split AC.
Moreover, people who live on rent can easily use this portable AC and can frequently relocate it from one place to another place.
Working Process of an Air Conditioner
Here come the biggest myths that the air conditioners generate cooling. But it’s wrong it don’t produce cooling.
Rather this machine eliminates the heat and makes the room cool gradually.
Through this entire procedure, it will help you get cozy and feel chilled in the scorching summer.
It is very essential to know the scientific functioning procedure of an AC.
Mainly, ACs function on the three rules. These three rules include evaporation, condensation, and compression.
Factors To Consider Before Purchasing The Best Air Conditioner
Now, before purchasing the best air conditioner, you should consider the followings:
Size of Air Conditioner (AC) – Tonnage
Before buying the exact tonnage AC first you need to know what is tonnage.
When we talk about an AC size or tonnage we are actually talking about the amount of heat it removes per hour and not the weight of an AC.
What is Tonnage of an Air Conditioner?
Ton is considered as the cooling capacity of an AC. Tonnage is the amount of heat that the AC removes from the room within one hour.
The mathematical unit of tonnage is measured by BTU. BTU stands for the British Thermal Units. It is the amount of heat required to raise 1 pound of water by 1 degree Fahrenheit.
The measurement is done as 3,412 BTU = 1Kw/hr.
For example, you can see 1 ton is equal to 12000 BTU/hour and a 2-ton AC unit would be rated at 24,000 BTU/hr.
The higher tonnage AC will provide more cooling effect.
In the market, when you browse through the AC units, you will see air conditioners of various tonnages. Several available AC tonnages are 0.75-ton, 1-ton, 1.5-ton, 2-ton, and many more.
How To Choose the Right Tonnage of an Air Conditioner?
Now, the question is that what is the right size of AC for your room. Frankly speaking there is no specific answer to this question.
Because the decision depends on several factors like room size, number of people in room, number of appliances in room, etc.
The following table will help you choose the right size of AC according to the room size.
|Size of the Room||Recommended AC Size|
|0 to 80 square feet||0.75 Ton|
|80 to 120 square feet||1 Ton|
|120 to 180 square feet||1.5 Ton|
|180 to 300 square feet||2 Ton|
Electricity Consumption of the Air Conditioner
We all usually get concerned about electricity consumption when we purchase any electric device.
A common question comes to mind is how much electricity it will consume.
The electricity consumption of air conditioner also depends on several factors like star rating, tonnage, usage of the AC, and many other aspects.
Modes of Operation of the Air Conditioner (AC)
You can use the AC in various modes such as cool mode, fan mode, dry mode, and many more.
Here, we will discuss the modes of the operation of the AC as the electricity consumption depends on it as well.
Cool mode is the default mode that you will see in every AC. This mode depends on the temperature and the setting of the fan speed.
To activate this mode, you have to set the temperature of your AC between 24 to 26 degrees centigrade.
This range is considered as the most comfortable temperature range to assure maximum efficiency.
Turbo or Quick Cool Mode
Quick-cool mode is not an electricity-saving mode at all. You can see this feature in many AC units. With this mode, the AC starts functioning at a temperature setting of 16 to 18 degrees centigrade.
Dry mode is the perfect mode that you should use in a humid weather condition. Like if you live in a place near a sea, you can use this mode.
The dry mode of the AC removes the humidity from the air and makes the room cool automatically. During this mode, the fan of the AC runs at lower speeds, and the compressor runs for a shorter period in more extensive cycles.
The main objective of the dry mode is to make the room cool by removing the humidity.
In the fan mode, the compressor of the AC remains off.
So that it can save energy by this procedure, but it does not make the room cool. Even a ceiling fan will do a better job than the fan mode of the AC.
It is a specialized mode that helps the AC to increase the temperature of the thermostat by 1 degree every hour.
It keeps growing until the temperature enhances by 2 degrees.
At night the outer side becomes already cooler; hence this mode ensures less electricity consumption.
Power Saving Mode
In this particular mode, the compressor of the AC shuts down while the temperature of the air reaches the level set in the thermostat.
During this mode, the fan keeps running to maintain the coolness.
When the temperature reaches extreme at a certain level, the compressor starts to function again.
Here you have to keep in mind that the compressor is the largest consumer of electricity.
As the compressor flutters between the on and off position, during this mode, the AC consumes less electricity.
6th Sense Cooling Mode
You will find the 6th sense cooling mode only in the Whirlpool AC units. In these AC units, the technology adjusts the speed of the fan that depends on the temperature inside the room.
This mode is better than the cool mode.
After considering different modes of the AC, you have to consider some other aspects that will influence the electricity consumption of the air conditioner.
Tips To Reduce Energy Consumption of Air Conditioner
- Keep the windows closed.
- Use sleep mode in your AC at night.
- Keep the AC vents clean.
- Service your AC timely.
- Use an anti-bacterial filter.
- Use the Wi-Fi connectivity feature to switch on your AC.
- During monsoon use the AC with dehumidifier feature.
- Use the AC with an auto-clean function feature.
Energy Efficiency (EER, SEER, ISEER, CoP, BEE Star Ratings) of the AC
EER, ISEER, CoP, and Star ratings are such important factors that affect the efficiency of AC units. Therefore energy efficiency is also a vital aspect to consider.
EER (Energy Efficiency Ratio)
EER is a very vital ratio that differentiates between AC units. Scientifically EER is the amount of heat that is removed per hour, and it is divided by the amount of power consumed.
Therefore, we can say EER is equal to BTU/hr/watt. Remember that the higher EER will offer the better performance of the AC unit.
It happens as the AC will be able to remove more heat per hour per unit of power consumed.
So, you may consider the best AC with higher EER.
SEER (Seasonal Energy Efficiency Ratio)
Internal and external temperature is a vital thing that affects the performance of the AC. If the outside temperature is warmer, the AC will consume more electricity to make the room cool.
In monsoon and winter, the temperature is much less than in summer. So, here you can see that the EER of the AC varies according to the seasons.
ISEER (Indian Seasonal Energy Efficiency Ratio)
The concept of both SEER and ISEER is same. But here two more factors you have to consider.
CSEC (Cooling Seasonal Energy Consumption): CSEC means the total energy that is consumed by the AC when it remains in the active mode.
CSTL (Cooling Seasonal Total Load): CSTL means the total amount of removed heat by the AC unit while it is active.
Now, ISEER is equal to total amount of heat removed to the total amount of energy consumed, i.e. ISEER = CSEC/CSTL
CoP (Coefficient of Performance)
CoP or Coefficient of Performance is a ratio of useful heating or cooling provided to work required.
To understand the concept of CoP, you have to do some simple mathematical calculations. For this calculation, you should know the relation between KW hr and BTU.
We can say that 1KW hr is equal to 3412 BTU or 1 KW is similar to 3412 BTU/hour.
Therefore, 1 W is equivalent to 3.412 BTU/hr.
The CoP is the amount of heat that is removed by the air conditioner in Watts, and it is divided by the power consumption in Watts.
Therefore, CoP does not have any units. A higher CoP will offer higher efficiency of the AC unit.
Also, remember that EER is equal to 3.412 X CoP.
When you are planning to buy your ac, you have to look for the star ratings as well. The stars are prescribed by the BEE (Bureau of Energy Efficiency), Department of Energy Savings Government of India.
Into this formulation procedure, a lot of factors go into it. Here, we will provide charts of star ratings for Window AC and Split AC for 1/12/2016 to 31/12/2017.
Below is the defined range of ISEER for Inverter ACs:
In these tables, you can see the star ratings with the EER. While you purchase an AC unit, you will see this table as it is a mandatory part of AC manufacturers to include the EER on the star rating sticker.
Also, remember that the 5-star AC is always more expensive than a 4-star AC. Moreover, you will save a lot of energy consumption for an extended period.
There are some other aspects too, like CSTL, and CSEC, that impact on the performance of an AC which we have discussed earlier.
Some Other Important Points to Consider
Apart from the above mentioned jargon, there are some other points that you have to understand.
Rated Cooling Capacity
Rated Cooling Capacity is a ton of an AC unit. It equals 12000 BTU per hour.
Maximum cooling capacity
It is also measured in tons. For instance, you can see that a 2-ton AC can remove 24000 BTU of heat per hour from a room. Though the previously discussed aspects also impact the process.
It is recommended that you should not purchase an over sized AC as it will affect the performance of the air conditioner.
Rated Power Input
You will see the rated power input on the star rating label. It is a vital part of AC manufacturers to include this figure.
It is equal to the power consumption in Watts when the AC functions at 100% load. A 1.5-ton AC consumes near around 1500 W/hr.
If you use the AC continuously for 5 hours, the consumption is not 1.5 to 2 times 5. It happens as the compressor switches off and on repeatedly.
Hence, consumption will be less.
Half Power Input
The half power input also works by the above concept. It is the power consumption in Watts when the AC functions at 50% of the load.
Maximum Power Input
It is also a type of power consumption when the AC functions at its maximum tonnage capacity. This figure will be different from the Rated Power Input for the tolerance of + or – 5% permitted by the BEE.
Concept of Inverter AC
Inverter AC is a type of air conditioner that works on inverter technology and saves a lot of power.
In a regular AC, you can see the full capacity of the compressor when the AC is functioning.
When the temperature reaches the optimum stage, the compressor switches off, and the fan of the AC continues to operate.
After the temperature rises above the threshold limit, the compressor starts to work again and works with full capacity.
Here, you should keep in mind that the compressor only works on full and zero.
Inverter ACs do not work in the same procedure. Here, the compressors function with multiple speeds.
In these ACs, the compressor never switches off, and it always remains on.
As the compressors run at various speeds, hence it draws less power. The Inverter ACs mostly functions like the accelerator of a car.
In a car, when we want to increase the speed, we have to press on the accelerator. And when you want to slow down the speed, you have to remove your foot from the accelerator.
Just in this same way, the inverter AC works, and you also will get the power-saving feature only in the split AC models.
Now comes the benefits, the only benefit of using the Inverter AC is that these are highly energy efficient.
You may compare a 3-star Inverter AC with the 5-star typical split AC.

Inverter AC vs Non Inverter AC
- The basic difference between these two types of AC is that the inverter AC can run at various speeds and variable tonnage. On the other hand, non-inverter AC units run at a constant tonnage and speed.
- Inverter AC can adjust their speed and tonnage according to the heat of the room. On the other hand, non-inverter AC units don’t have this capacity.
- As per efficiency, inverter AC units are more efficient than the non-inverter ACs.
The size of the room and number of people there also have an impact here. Hence, you have to choose the perfect AC unit according to all these aspects.
Now, we will provide a basic chart to differentiate between an Inverter AC vs Non-Inverter AC.
|Aspects||Inverter AC||Non-Inverter AC|
|Compressor motor||Always on||On and Off|
|Reach to desired temperature||Quickly||Takes time|
Here, we will provide the BEE data of 2018 about the power consumption of several AC units with various ratings and tonnage.
This table shows that the higher star rating AC units with lower consumption.
Here, you also can see that the inverter AC units are extremely energy efficient.
|No. of Stars||0.75 Ton||1 Ton||1.5 Ton||2 Ton|
|1 Star Non Inverter||627||843||1246||1648|
|2 Star Non Inverter||596||800||1184||1626|
|3 Star Inverter & Non-Inverter||542||747||1104||1448|
|4 Star Inverter||464||645||945||1293|
|5 Star Inverter||450||554||840||1113|
Type of Air Conditioner Compressor
Compressor is one of the most vital aspect of an AC. You may consider the compressor as the heart of the AC unit.
Therefore, it is essential to know the functioning process of the compressor. Now we will see the role of the compressor in an AC.
The main job of the compressor of an AC is to compress the refrigerant gas to high pressure. It also converts the refrigerant gas into a high-pressure liquid at high temperatures.
This condenser coil passes through the liquid that takes out the heat from the liquid and then releases it in the surroundings.
Then the expansion valve reduces the pressure and converts the liquid into gas.
This gas passes through the evaporator coils. Then the evaporator coils absorb the heat from the room and make the rooms cool.
There are two types of compressors namely Reciprocating Compressors and the Rotary Compressors. Below is the difference between Reciprocating vs Rotary Compressor.
Reciprocating vs Rotary Compressors in Air Conditioners
This type of compressor is similar to the engine of the automobile. This compressor works on the concept of the cylinder and piston.
The piston works in back and forth motion, and it results in compression and release of the gas.
- Reciprocating compressors are easy to maintain.
- These compressors are capable of working at higher pressures.
- These compressors produce a lot of noise.
- With these compressors, the air comes out at a high temperature.
This type of compressor consists of several rotors that have very little clearance between them. The rotors of these compressors rotate in opposite directions.
And the air passes through the rotors and emanates at high pressure.
- The AC units with this type of compressors are suitable for large industries and offices.
- These compressors make less noise.
- With Rotary compressor, the air comes out at a lower temperature.
- This type of compressor is more expensive than Reciprocating compressors.
- In these compressors, higher usage is needed for maximum working.
You should consider the pros and cons of both of these compressors for your ac.
Also, remember that the Reciprocating Compressors are suitable for small offices and homes, whereas Rotary Compressors are suitable for big industries and offices.
Condenser Coil Material of the AC
AC units work is based on condensation, compression, and evaporation. The entire procedure involves moving the refrigerant gas inside the coils.
These coils are mainly made of two materials, copper and aluminium.
Here, many people get concerned about which coil is better than the copper one or the aluminum coils. In previous times, the coils were mainly made of copper.
Then in 1970, General Electronics made the drastic change when they substituted copper coils with the aluminum coils. Since that particular year, the debate started between the copper coil vs aluminum coil.
Copper Coil vs Aluminium Coil
Here, we will focus on several aspects of choosing the proper type of coils.
Heat Transfer: We all know that copper has higher efficiency of heat transfer than aluminum. Therefore copper coils are considered as a better heat exchanger than the aluminum coils.
Malleability: Aluminium is considered as more malleable than copper. Therefore, aluminum can be molded into any desired shape than copper.
Consequently, you can go for aluminum coils to make the best AC.
Strength: While considering the strength factor, copper is always stronger than aluminum. Even copper coils also last longer than aluminum coils.
Cost Factor: While purchasing any electronic device, the cost factor is a considerable aspect to consider. Copper is more expensive than Aluminium.
Therefore you can go for the AC units with aluminum coils to save your money.
Corrosion: AC units work in a damp environment. There is always a possibility of corrosion.
This corrosion causes the formation of a layer over the coils and also affects the conductivity.
People who live near the sea should be highly cautious about this matter.
Maintenance: You can see that the condenser coils are always placed on the external AC units. They have to face extreme weather conditions.
Copper coils are easier to maintain, whereas you have to keep the aluminum coils into heavy-duty cabinets. Therefore, they are difficult to maintain.
Microchannel Condenser Coils: Microchannel Condenser coils are also aluminum coils. These coils are flat aluminum tubes that come with minute holes through which the refrigerant flows.
The entire set up is made up of aluminum.
So, there is no chance of galvanic corrosion. Therefore, these coils are appropriate for ACs that work in coastal regions.
Samsung AC manufacturers use this technology that is called Multi Jet technology.
Blue Fin Condenser Technology: When it’s about corrosion, you should know that there are some technologies available available in the market which work to reduce corrosion.
Blue Fin Condenser is such a technology. This technology paints coils with anti-corrosive materials. Hence, it increases the overall life of the AC units.
You have to consider these technologies to avoid corrosion.
Nature of Coolant Used In The Air Conditioner
Coolant is also known as air conditioning refrigerant. It is a vital part of air conditioning and refrigeration equipment.
The primary function of the air conditioning refrigerant is to absorb the heat from the room.
It also delivers the heat outside. Once the temperature of the room gets eliminated, the room becomes cold.
The coolant remains in the form of gas that is compressed through the compressor at high pressure. Then it converts the gas into a liquid.
At extreme pressures, the liquid reaches a very high temperature.
This liquid passes through the condenser coils, where the temperature of the liquid comes down, and the pressure remains high.
By releasing the high-pressure cold liquid, the AC units reduce the pressure.
Then the liquid travels through the evaporator coils. The heat gets absorbed by the cold liquid and eliminates the heat and makes the room cold.
The fans present in the AC unit also help to sustain the temperature. After absorbing the heat, the liquid evaporates and changes itself into a gas again.
The same procedure gets repeated continuously. This is how the AC unit functions.
Hence, naturally, air conditioning refrigerant is a vital aspect to consider.

Types of Refrigerants
After knowing what a refrigerant is, now we will go to the types of refrigerants.
Chlorofluorocarbons (CFC): Chlorofluorocarbons was the initial one that was used in AC units all over the world. These refrigerants are also known as R12 refrigerants.
Though these refrigerants were very effective, they played a massive role in the depletion of the ozone layer in the atmosphere.
Now, these types of refrigerants are not used in AC units.
Hydrochlorofluorocarbons (HCFC): For environmental concerns CFC refrigerants were replaced with the Hydrochlorofluorocarbons or HCFCs. This type of refrigerant is known as R22.
It is the most common type of coolant used in AC units in India.
Though this coolant is also not so eco-friendly. Therefore, there you can see indications that these refrigerants will be phased out over the next 4-5 years.
Hence, you have to be careful when you buy air conditioners with this coolant.
Hydrofluorocarbons (HFC) In comparison with the R22 coolant, the HFC refrigerants do not deplete the ozone layer much. Therefore these refrigerants are much eco-friendly.
Presently, there are three types of HFCs used that include R410A, R32, and R134.
Hydrocarbons (HC) These types of coolants are the most environmentally friendly. These AC coolants are known as R290 and R600A.
These refrigerants have zero effect on the ozone layer.
They have high energy efficiency and are also the greenest refrigerants available in the market today.
Moreover, we all have a fundamental responsibility to our environment.
Hence, choosing the AC coolant rightly can play a big part in this regard.
Brand and After Sale Service
There are many top air conditioner brands as well as many normal brands available in the market.
The main difference between good reputed brand and a normal brand is the quality of the product and the after sale service.
A top brand means great quality of product with good after sale service.
Therefore, we always recommend that you go with a reputed brand and always check the warranty information before purchasing.
An AC with a maximum warranty period on the compressor as well as on other parts will save you lots of money in future.
In the market, you will get several AC brands such as LG, Carrier, Voltas, Whirlpool, Hitachi, etc.
These are considered as the best AC brands in India.
Although today ACs are no more a luxury item but they don’t come cheap also. The bigger the tonnage the costlier the AC.
Also most of the branded ACs are bit costly compared to non branded ones. But you will get good quality product with good warranty and after sale service.
Also the inverter ACs are costlier than normal ones. But they will save you lots of money in long run.
Therefore, we recommend that you choose it wisely as you cannot change an AC every year.
