Best AC in India – Buying Guide

What is the difference between a computer and an air conditioner? A computer requires ‘Windows’ to be open for effective functioning whereas the AC needs the windows to be shut 🙂

Having begun on a lighter note, we shall dig deep and look at the various aspects that you should understand while installing air conditioners in your homes and offices.

With the increase in the demand for AC units, you have more brands of air conditioners in the market. The awareness levels among people have increased as well. But, still, you need to be aware of various features before investing in the right AC for your homes. This buying guide aims to make things easy for you.

Working of the air conditioner

There are two explanations for the working of the air conditioner. One is the scientific explanation whereas the other one is a simpler one that could be understood by all. We shall begin with the simpler one.

Heat and cold are synonymous with each other. The absence of heat is cold and vice versa. The AC works on a similar principle. It removes the heat from inside the rooms. Thus, you experience the rooms getting cooler.

Does this not bust one of the biggest myths that air conditioners generate cooling? No, they do not do that. They eliminate the heat thereby cooling the rooms

Refrigeration cycle: 1) condensing coil, 2) expansion valve, 3) evaporator coil, 4) compressor

We now come to the scientific explanation of how Ac units work. Basically, the air conditioner works on the three principles of evaporation, condensation, and compression. We shall look into these processes in brief to get a fair idea.

1. Every AC unit has a refrigerant gas (we shall speak about this gas later in the article). The first step in the working of the AC is the compression of this refrigerant gas. When you compress a gas, it turns into a high-pressure hot liquid.

2. This hot liquid then flows through the condenser coils where the heat escapes while cooling the liquid. But, the liquid is still under high pressure.

3. The expansion valve comes into play by converting the high-pressure liquid into a low-pressure one.

4. This low-pressure liquid flows through the evaporator coils of the AC. In doing so, it absorbs the heat from the room. This heat converts the liquid into gas once again. As the process of absorption of heat goes on, you experience cooling of the room. Now, you have to ensure that you do not increase the existing heat in the room. This explains why you should shut the windows. We had spoken about this fact in the initial parts of this article.

5. We are now again back to square one. The refrigerant gas comes back into its original form. The process keeps on repeating continuously.

You have different kinds of AC units. In a single-unit window AC, the compressor, condenser, and the evaporator are located in a single unit. In case of a split AC unit, you have the compressor and the condenser situated in the outdoor unit whereas the indoor unit comprises of the evaporator coils.

Size of the AC – Select the right Tonnage

Various factors go into the selection of the right size of the AC. Let us look at all of them in brief.

1. City where you live: The climate of the city where you live is important because you need air conditioners of higher capacities when the outdoor temperature increases. For example, the summers in Delhi can see temperatures touching 45 degrees Centigrade whereas it would hover around the 38 to 40-degree mark in a city like Chennai at the same time.

2. The area and the volume of the room where you install the AC are very important.

3. The location of the room is vital because a lot depends the rooms can get hotter if the ceiling gets direct sunlight from the top during the day. The same applies to the side walls as well.

4. The daily usage of the AC unit is essential and so also is the duration of the usage in terms of months during the year.

What is the concept of tonnage of the AC?

As you browse your way through the AC units in the market, you find the air conditioners of different tonnage such as 1-ton, 1.5-ton, 2-ton, and so on.

What does this imply?

The tonnage is the amount of heat the air conditioner removes from the room in one hour. The mathematical unit for tonnage is BTU (British Thermal Units). 1 ton equals 12000 BTU. Higher the BTU, the greater is the cooling effect.

We have just seen that the size/tonnage of the AC depends on various factors. You can also add a couple of other relative factors such as a number of occupants in the room, the amount of furniture/appliances in the room, etc.

Electricity consumption of the AC units:

How much electricity does an air conditioning unit consume? This is a common question on the minds of all AC buyers. It again depends on various factors like the tonnage, star rating, and usage of the AC and so on. Let us look at some of the principal aspects in brief.

Modes of operation of the AC units

There are various modes in which you can use the AC. The consumption of electricity depends on the mode of operation of the AC.

Cool Mode

This is usually the default mode in any AC. It depends on the temperature and the fan speed setting. Ideally, you should keep the temperature set at 25 degrees Centigrade. This is the most comfortable temperature to ensure maximum efficiency.

Fan Mode

In this mode, the compressor remains off. You save energy in the process but it does not result in the cooling of the room. A ceiling fan can do a better job.

Dry Mode

This is the ideal mode to use in a humid climatic condition like the type you experience in places near the sea. The purpose of using this mode is that it removes the humidity from the air thereby cooling the room automatically. The fan runs at lower speeds and the compressor for shorter duration in larger cycles. The principal objective is to remove the humidity and not cool the room as such.

Energy Power saver mode

In this mode, the compressor shuts down when the temperature of the air reaches the level set in the thermostat. The fan keeps running to maintain the coolness. When the temperature exceeds a certain level, the compressor starts functioning again. The compressor is the largest consumer of electricity. As it oscillates between the on and the off position, it consumes less electricity.

Quick cool mode

Strictly speaking, this is not an electricity-saving option. But, you have this feature in many Ac units where the AC starts functioning at a set temperature of 16 or 18 degrees Centigrade as against the 25 degrees in the normal mode.

Sleep mode

This is a special mode by which the AC increases the temperature of the thermostat by 1 degree every hour until it increases the temperature by 2 degrees. At night, the exterior is already cooler. Hence, this facility ensures that your AC consumes less electricity.

6th Sense cooling

This mode is available only in the Whirlpool AC units where the technology adjusts the fan speed depending on the temperature inside the room. This is better than the cool mode.

You have just seen the various working modes of an AC. Choosing the right mode for your AC can go a long way in reducing your electricity consumption.

We shall also look at some other aspects that affect electricity consumption.

Size of the Room

The principal job of the air conditioner is to remove the heat from the room thereby making it cool. Hence, a lot depends on the size of the room. Understand that the electricity consumption of an AC unit depends on the amount of heat present in the room.

A 1.5-ton AC in a room measuring 120 sq feet will work differently as compared to the same AC in a room measuring 150 sq feet. This is because of the greater volume of hot air.


Some places in India like Delhi or Nagpur become very hot in the summer months. However, the climate remains dry. On the other hand, places like Mumbai and Chennai experience a great deal of humidity.

It might not be hot but the humidity can be a draining experience. Your AC will work differently under both circumstances.

The former case requires the AC to cool down the rooms whereas the principal job of the AC in the latter instance is to remove the humidity. Thus, an AC with a larger size and tonnage is perfect for the hot places whereas a smaller AC unit would suffice to remove the humidity.


This is a surprising factor, but colours do affect the performance of the AC. Darker colours absorb more heat. Hence, they take a longer time to cool. Hence, it is always better to have lighter coloured walls and curtains.

Number of people

The more the number of people in the room, the higher is the emission of heat from the bodies. Hence, you experience that you require AC units of higher tonnage to cool rooms having a higher number of people.

A 150 sq feet room in your house can work with a 1.5-ton AC whereas the room of the same size will need two 2-ton ACs in case you run a coaching class/school with say 20 to 25 kids in the room.

Electrical appliances

Just as people emit heat, so also do electrical and electronic appliances. The simple appliances like bulbs emit heat. Hence, it is beneficial to have LED lights in your room. They not only save electricity but also emit less heat.

Having a lot of furniture in the room can also increase the electrical consumption of the AC. It is better to keep your cupboards and shelves closed in an AC room. The walls absorb heat as well. Hence, insulating the walls can also help in reducing electrical consumption.

Inverter AC – Concept, Working, and Benefits

The most common term doing the rounds today is ‘Inverter AC’. What is an inverter AC? If you think that this is an AC unit that can work on the home inverters, I am afraid, you are sadly mistaken.

The home inverters have nothing to do with inverter AC. These AC units work on the Inverter Technology whereby they save a lot of power.

In a regular AC, the compressor works at full capacity when it is on. On reaching the optimum temperature, the compressor switches off and the fan continues to operate.

Once, the temperatures rise above the threshold limit, the compressor starts again and works at full capacity. This entails that the compressor works at only two speeds, full and Zero.

This is not the case with inverter ACs. These compressors work at variable speeds. In this technology, the compressor never switches off. It is always on. But, it runs at varying speeds thereby drawing less power.


It is more or less like the functioning of the accelerator in a car. As you increase the speed, you press on the accelerator. In case you want to slow down, removing the foot from the accelerator pedal is enough. The vehicle starts cruising without consuming any fuel. Thus, inverter technology is a power-saving feature available only in the split AC models.

The benefit of using inverter AC units is that they are highly energy efficient. A 3-star inverter AC is equivalent to the 5-star normal split AC. This explains the efficiency of the inverter AC vis-à-vis the non-inverter ACs.

Inverter AC vs Non-Inverter AC

We shall see the difference between the efficiency of an inverter AC and the non-inverter AC.

The basic difference between the inverter AC and the non-inverter AC is that the former is capable of running at variable speed and variable tonnage. The non-inverter AC units run at a constant speed and tonnage.

Inverter AC units are capable of adjusting their speed and tonnage according to the heat inside the room. The non-inverter AC units do not have this capacity.

Efficiency wise, inverter AC units are 7% more efficient than their counterparts in the same star rating category.

Inverter AC vs non Inverter AC

Do you have the ideal setting in your room at all times? No, the numbers of people vary and so does the temperature levels. Hence, you need an AC unit that is capable of adjusting to the ambience in the room. The inverter AC units are capable in this regard.

We reproduce the BEE data of 2018 about power consumption of various AC units if different tonnage and ratings. This data assumes total consumption for 1600 hours.

This table shows that higher the star rating, the lower is the consumption. It also indicates that the inverter AC units are extremely energy efficient.

Copper Coil vs Aluminium Coil

AC units work on the basis of compression, condensation, and evaporation. This involves moving of the refrigerant gas inside coils in gaseous as well as liquid forms. The question now arises as to which of the coils is better, copper or aluminium.

In the olden times, the coils were primarily made of copper. Subsequently, General Electronics made the revolutionary change in 1970 when they substituted copper coils with aluminium coils. Since that day in 1970, the debate between aluminium and copper coils continues.

We shall throw some light on the various aspects of choosing the right kind of coils for your AC.

Heat transfer

Copper has a higher heat transfer coefficient than aluminium. Hence, it proves to be a better heat exchanger than aluminium

Cost factor

Aluminium is cheaper than copper. Therefore AC units with aluminium coils are cheaper.


Aluminium is more malleable than copper. Hence, it is possible to mould aluminium into any desired shape more easily than copper. Thus, aluminium is the preferred choice for making AC coils.


Now, copper is undoubtedly stronger than aluminium. Cooper coils have the reputation of lasting much longer than aluminium coils. They need fewer repairs as well.


You notice that the condenser coils are always placed in the external units. Hence, they are subject to the vagaries of weather. Copper coils are easier to maintain whereas you need to keep the aluminium coils in heavy-duty cabinets thereby making them difficult to maintain.


The AC works in a damp environment at all times. Hence, there is always a danger of corrosion. This corrosion results in the formation of a layer over the coils thereby affecting its conductivity. People living in humid areas near the sea should be extremely cautious about this aspect.

Blue Fin Condenser Technology

bluefin condenserOn the subject of corrosion, one must add that there are technologies available today that work towards reducing corrosion. One such technology is Blue Fin Condenser. In this technology, they paint these coils with anti-corrosive materials thereby increasing the overall life of the AC units. 

Microchannel condenser coils

microchannel condenser coilsIn fact, you find the microchannel condenser coils to be aluminium coils. They are flat aluminium tubes having minute holes in them through which the refrigerant flows. Since the entire set up is of a single metal, aluminium, there is no question of galvanic corrosion.

Hence, these coils are a good option for ACs working in coastal regions. Samsung uses this technology in its AC and calls it the MultiJet technology.

Reciprocating Vs Rotary Compressors

You have seen the difference between aluminium and copper coils. Now we shall shirt our attention towards compressors. Let us now look at the difference between the reciprocating and rotary compressors.

Anyone will say that the compressor is the most important component of any AC unit. In fact, it is the heart of the unit. Hence, one should have knowledge of how compressors work. Let us see the role of the compressor in an AC.

The principal job of the compressor is to compress the refrigerant gas to a high pressure thereby converting it into a high-pressure liquid at high temperature. This liquid passes through the condenser coils that take out the heat from the liquid and release it to the surroundings.

However, the pressure remains high. The expansion valve then reduces the pressure and converts the liquid into gas that subsequently passes through the evaporator coils. The evaporator coils absorb the heat from the room thereby cooling the rooms.

There are two major types of compressors in use in the AC units.

Reciprocating compressor – This is similar to the engine of the automobile that works on the concept of the cylinder and piston. The piston works in a back and forth motion resulting in compression and release of the gas.

Reciprocating compressor

Rotary compressor – This arrangement consists of a number of rotors having very little clearance between them. These rotors rotate in opposite directions whereby the air passing through them emerges at a higher pressure.

Rotary compressor

Let us look at the pros and cons of the reciprocating and rotary compressors to understand which of the technologies is better.

Reciprocating Compressors Pros

  • Easy to maintain
  • Capable of working at higher pressures

Reciprocating Compressors Cons

  •  Produces a lot of noise
  •  The air comes out at a high temperature

Rotary Compressors Pros

  • Good for large offices and industries
  • Less noise
  • Air comes out at a lower temperature

Rotary Compressors Cons

  • Expensive as compared to reciprocating compressors
  • Higher usage is required for optimum working

One can conclude from the above pros and cons that the reciprocating compressors are perfect for homes and small offices. The rotary compressors are ideal for heavy-duty uses such as in offices and industries.

Air conditioning Refrigerants

Normally, when you find that the AC does not deliver enough cooling, the mechanic suggests that you replace the coolant. What exactly is this coolant or the gas as they call it in many parts of the world?

Refrigerant Global Warming Poetential Ozone Depletion Potential
R 22 1810 Medium
R 410A 2088 Nil
R 32 675 Nil
R 134A 1430 Nil
R 290 3 Nil
R 600A 3 Nil

Coolant is also known as the refrigerant and forms an important part of air conditioning and refrigeration equipment. The principal function of the air conditioning refrigerants is to absorb the heat from the room and deliver it outside. Once you eliminate heat from the room, the air in the room automatically cold.

The coolant is originally in the form of a gas. The compressor compresses this gas at high pressure and converts it into a liquid. At such extreme pressures, the liquid has a very high temperature.

This liquid passes through the condenser coils where the temperature of the liquid comes down considerably but the pressure remains high. On releasing the high-pressure cold liquid through an expansion valve, the AC units reduce the pressure.

This liquid then travels through the evaporator tubes/coils. This cold liquid absorbs the heat from the rooms and eliminates it thereby making the air in the room cold. The fans in the AC unit help in sustaining the temperature.

On absorption of the heat, the liquid evaporates and converts into gas once again. The same process is again repeated continuously. This is how an AC works. Thus, you have seen that the refrigerant is the principal component of any AC.

Various types of refrigerants have been in use over the years. They are as follows.

Chlorofluorocarbons – CFC

These were the initial coolants used in AC units all around the world. They were also known as R12 refrigerants. They were effective, but they played a great role in the depletion of the ozone layer in the atmosphere. This led to the discontinuance of the manufacture of this R12 refrigerant. Now, no AC uses this coolant anywhere in the world.

Hydrochlorofluorocarbons – HCFC

Environmental concerns led to the replacement of the CFCs by the HCFCs. This refrigerant, popularly known as R22 is the most common coolant used in AC units in India today. However, this coolant is also not very environmentally friendly. Hence, there are indications that these coolants will be phased out over the next 4 to 5 years.

This is why you should be very careful while choosing your AC. If the manual indicates the use of R22 as the coolant, it is advisable not to buy that AC because it is an out-dated one. This is in spite of the fact that the majority of AC units use this coolant in India.

Hydrofluorocarbons – HFC

Compared to the R22 coolant, the HFCs do not deplete the ozone layer. Hence, they are comparatively environmentally friendly. You have three types of HFCs in use today (R410A, R32, and R134). The world has moved ahead and switched over to a more environmentally friendly refrigerant, the hydrocarbons. India is also close on the heels of these developing nations and has plans to phase out the hydrofluorocarbons in the coming years.

Hydrocarbons – HC

The search for the most environmentally friendly coolant has brought the world to HCs. AC manufacturing companies all over the world today use R290 (Propane) and R600A (Iso-Butane) as refrigerants. They are reputed to have zero effect on the ozone layer. Hence, they are also referred to as green refrigerants.

The inverter AC uses such types of coolants in them. Research is still on in this field to discover the best environmentally friendly coolant. Until the time they come up with a better coolant, the R290 and R600A will have a field day.

One should have awareness about these minute factors while deciding to purchase AC units for your house. Every person in the world has a duty towards maintaining the sanctity of the environment. You need to leave a better world for your children to live in. Small things such as choosing the right coolant for your AC and refrigerator can play a big part in this endeavour.

Star Ratings, EER, CoP, ISEER

Let us now look at the factors affecting the efficiency of the AC units and the concept of star ratings.

Energy Efficiency Ratio: (EER)

The EER is a very important ratio that differentiates between AC units. Scientifically, EER = Amount of heat removed per hour divided by the amount of power consumed.

Thus, EER = BTU/hr/Watt

The higher the EER, the better is the performance because the air conditioner removes more heat per hour per unit of power consumed. Thus, you can deduce that an air conditioner with a higher EER is more efficient.

Co-efficient of Performance: (CoP)

You need to do some simple mathematical calculations to arrive at the CoP. In order to understand the concept of CoP, you should know the relation between BTU and KW hr.

1 KW hr = 3412 BTU. Alternatively, you can say that 1 KW = 3412 BTU/hr.

Therefore, 1 W = 3.412 BTU/hr

Now, CoP is the amount of heat removed by the air conditioner in Watts divided by the power consumption in Watts. Hence, CoP does not have any units. Higher the CoP, higher is the efficiency of the air conditioner unit. Let us now look at the relation between EER and CoP.

EER = 3.412 X CoP

Star Ratings

Whenever you venture to buy an AC, the first thing you normally look out for the star ratings. What exactly are the star ratings?

The Bureau of Energy Efficiency, Department of Energy Savings Government of India prescribes these star ratings for various electronic products. A lot of factors go into the formulation process.

These ratings are fixed for specific periods. The latest star ratings released by BEE are from January 01, 2018, to December 31, 2023.

Indian Seasonal Energy Efficiency Ratio

January 01, 2018, to December 31, 2020

January 01, 2021, to December 31, 2023

Star Rating



Star Rating

































This table suggests that you should look at the star ratings along with the EER. It is mandatory on the part of AC manufacturers to include the EER on the star rating sticker.

Understand that the 5-star AC is always going to be more expensive than the 4-star AC. However, you do save a lot in energy consumption over a long period.

There are other aspects to look into while we are on the topic of energy savings. They include the SEER, ISEER, and other terms concerned with the performance of the AC such as CSTL and CSEC. We shall look at all these terms in brief for the sake of better understanding of the subject.

Seasonal Energy Efficiency Ratio (SEER)

Among the various factors that affect the performance of the AC is the external and internal temperature. In case the temperature outside the house is more, the AC consumes more electricity to cool the interiors.

The temperatures in the rainy season and winters are much less than what you get in the summer season. Therefore, the EER of the AC varies depending on the season in which you use the appliance. This is the concept of SEER.

Indian Seasonal Energy Efficiency Ratio (ISEER)

The concept of SEER and ISEER is the same. However, you need to look into two additional factors as below.

Cooling Seasonal Energy Consumption (CSEC): Total energy consumed by the AC when it is in active mode

Cooling Seasonal Total Load (CSTL): Total heal removed by the AC in active mode.

Now, we come to the concept of ISEER.

ISEER = CSTL/CSEC (Total amount of heat removed to the total amount of energy consumed)

The BEE makes it mandatory for Indian AC manufacturers to declare the ISEER on the star rating label. 

EER Value


EER is an internationally approved concept.

ISEER is only for Indian seasonal conditions.

EER applies to non-inverter air conditioners.

ISEER applies to inverter air conditioners

EER is independent of seasonal changes.

ISEER depends on the seasonal temperature changes.

EER remains the same globally.

ISEER depends on Indian temperature changes.

Compared to ISEER, EER is less accurate.

ISEER is highly accurate compared to EER.

While on the subject of star ratings, you should be aware of certain terms and concepts regarding your AC units. You will come across these terms frequently. It is better to be aware of the same and ask questions to the dealer before deciding on the type of AC you wish to buy for your home.

Rated Cooling Capacity

The rated cooling capacity of an AC is ‘a ton’. This is equal to 12000 BTU per hour.

Maximum Cooling Capacity

The maximum cooling capacity is again measured in tons. For example, a 2-ton AC will remove 24000 BTU of heat per hour from the room. The requirement for the room can vary depending on various factors discussed earlier. It is advisable not to oversize the AC because it can affect the performance of the AC.

Rated Power Input

You find this figure on the star rating label. It is mandatory on the part of AC manufacturers to include this figure. This is equivalent to the power consumption in Watts when the AC runs at 100% load. A 1.5-ton AC will consume about 1500 w/hr. Hence, you can see that the AC will consume around 1.5 to 2 units per hour.

However, if you use the AC continuously for say 5 hours, the consumption is not 1.5 or 2 times 5. This is because the compressor switches off and on at regular intervals. Therefore, the consumption of 5 hours will definitely be less.

Half Power Input

By applying the above concept, the half power input is the power consumption in Watts when the AC runs at 50% of the load.

Maximum Power Input

This is the power consumptions when the AC runs at its maximum tonnage capacity. This figure will differ from the Rated Power Input because of the tolerance of + or – 5% allowed by the BEE. Even a 1.2 ton AC is marketed as 1 ton.

Now, you have seen the various factors that affect the electricity consumption of the air conditioning units.

Best Air Conditioner – Frequently Asked Questions

1. Which AC brand is the best?

There are innumerable AC brands available on the market. It is a tough task to choose the best among them. This guide will give you an idea of the aspects you have to look into while buying AC units. Energy efficiency is one. Environmental friendliness is another.

You have to look at the cost factor as well. Considering all the three major aspects, it is always better to go for inverter AC units. You have various companies that are specialists in the manufacture of AC equipment. The first names that come to mind are Carrier, Blue Star, Daikin, etc. Secondly, you have companies that manufacture various electronic appliances other than AC units.

The most prominent among them are Hitachi, Mitsubishi, LG, Voltas, etc. You have the local India brands like Onida and Godrej that manufacture ACs to suit Indian conditions. All these brands are reputed brands. You can go for the one that offers the maximum benefits at the minimum cost.

2. Which AC brand provides the best service?

It is better to check out beforehand as to whether the AC manufacturing company has provisions for servicing your AC in your city. Transporting it to another city is not a feasible job. Usually, the reputed manufacturers like Carrier and Daikin have arrangements with local service centres.

The Indian make AC units do not face this problem. It is better to read customer reviews before going for the right AC brand. The reputed AC brands mentioned above have such facilities. Nevertheless, check it out before you invest in the particular brand.

3. Is it safe to buy AC online?

Yes, it is. You have reputed websites like Amazon where you can order the best AC units at great discounted rates. There is absolutely no harm in buying AC units online, especially from the reputed eCommerce platforms.

4. is it OK to opt for AC with aluminium condenser?

The most common metals used for manufacturing condenser tubes are copper and aluminium. Both these metals have their advantages and disadvantages. Copper has a high heat transfer coefficient as compared to aluminium. At the same time, aluminium is extremely malleable and comparatively inexpensive.

But, they require higher maintenance. Therefore, you can opt for AC with aluminium condensers though copper is the preferred choice all over the world. Aluminium condensers are not bad either.

5. What is Blue Fin / Gold Fin technology?

Corrosion is the biggest enemy of these air conditioning units. Over a period, the condenser tubes suffer from corrosion thereby requiring replacement and repairs.

To overcome this problem, manufacturers use Blue Fin or Gold Fin technology whereby they paint the condenser tubes with special anti-corrosive paint. This improves the life of the AC unit. The only difference between Blue Fin and Gold Fin technology is that Gold Fin technology does not rust easily thereby increasing the life expectancy of the AC.

However, this technology is expensive as compared to Blue Fin. Both these technologies have their merits and demerits. It is up to the consumer to make the choice after considering all aspects.

6. Is stabilizer required for the Air conditioner?

Every AC has a voltage operating limit. You will find this range printed on the AC label. Check out if the area you live in has voltage fluctuations beyond these limits.

In case, it is so, you should invest in a stabilizer for your AC to protect it from voltage fluctuations. It is better to be safe than to be sorry. A stabilizer will not cost much when compared to your AC. Install one and do not worry about voltage fluctuations.

7. Which condenser is better for coastal areas?

Corrosion is the main problem that condensers face. Copper is an excellent metal for manufacturing condenser coils. But, copper is also unique for being the only metal to fall prey to formicary corrosion. This type of corrosion requires the presence of oxygen, water, copper, and an organic acid.

The worst part of this corrosion is that it is invisible to the naked eye. You find this type of corrosion in coastal areas where there is a lot of humidity in the environment. Usually, you see AC units having copper coils and aluminium fins. Such units suffer from galvanic corrosion. Hence, it is better to have a single metal for the condenser tubes as well as the fins.

The microchannel condenser coils are the best for use in coastal regions. Samsung uses this technology in the manufacture of condenser coils. The major AC manufacturers use Blue Fin and Gold Fin technology for coating the condenser coils.

8. What is Air Purifier, dust, bacterial filters in AC?

Indoor air has a lot of dust. This dust and bacteria can cause respiratory problems. In the normal circumstances when you do not use the AC, you keep the doors and windows of the room open. This ensures circulation of the air. But, when you operate the AC, you have to close the windows and doors. This entails that you inhale the same air.

The AC units have dust and bacterial filters that trap these ingredients from recirculation. The modern-day AC units come with air purifiers as well. This ensures that you have pure and clean air to breathe. You will understand the amount of dust in the air when you remove these filters from the AC for cleaning. Imagine the amount of dust you inhale in the normal course.

9. What is a dehumidifier?

In the normal course, the air contains a lot of humidity. Running the AC in normal mode entails that you circulate the humidified air through the machine. This is why you have the dehumidifier mode in the AC.

This is also known as a Dry mode where the AC removes the excess humidity from the room without any significant change in the temperature. Hence, people living in areas near the coast should go for ACs with dehumidifiers. They add to the comfort value of the AC.

10. What is a dual inverter AC?

You find this Dual inverter compressor in certain brands of LC AC units. The very name suggests that you have double the efficiency that you experience in a single inverter AC.

This technology ensures that the AC functions with less noise and cools faster as well. When it cools faster, it entails that the compressors function at low speeds most of the time. Hence, you save a lot in your electricity consumption

11. What is Mosquito Away technology?

The Mosquito Away technology is present in the latest brand of LG AC units. This technology is based on ultrasonic sound to keep away mosquitoes. The AC units emit this sound that is beyond the hearing power of humans.

But, it can discourage mosquitoes. LG uses this technology in their phones, washing machines, and televisions as well.

    • It is very hard to compare LG and Samsung Models that are in the same pricing range.

Both the Models are excellent for the price. Both are top brands and have wide range of range of service centers in India. It is better to opt for the brand that provides quick support at your place.

  7. Very nice informative article. Thank you for sharing. I am getting a couple of 1.5ton split ACs. As an eco friendly option i want to go for ACs with R290 over R32, but R290 is more flammable so is it advisable to buy a Godrej split AC compared to a Daikin or OGeneral or LG or Samsung all using R32? I understand that the manufacturers can ensure that the main unit is well and safely built, but for a split AC there is fitting done by local mechanics so could the pipeline be a potential fire hazard? I really want to do my bit for the environment but i am in a dilemma about how safe these R290 ACs would be vs the R32 units? I am in Delhi and we are getting ready for a scorching summer this time, Which 1.5 ton Ac would you advise? If price were not a consideration what’s the best option to go for.
    Thanks a ton in advance

      • Thank you so much for your reply. I really appreciate your suggestions. I had OGeneral window ACs in my rooms till now and their cooling was excellent but OGeneral or Daikin do not figure in your recommendations. If it is not too much trouble, may i ask why just to understand the reason?
        Once again thank you very much for your inputs.

  11. Hello, I am planning to buy one 1.5 and one 1 ton AC.
    Below are my suggested list:
    ****1.5 Ton****
    1. LG LS-Q18HNZD
    2. LG-LS-Q18ANZA
    3. Samsung AR18TY5QAWK

    ****1.0 Ton****
    1. LG LS-Q12FNZD
    2. LG-LS-Q12GWZA
    3. Samsung AR12TY5QAWK

    Please suggest ASAP.

    • All the three models you have mentioned are excellent. 5 Star Rating, Copper Condenser and Good ISEER Value. The Only difference is features

      The Samsung AR18TY5QAWK has dehumidifier and HD Dust filter
      LG KS-Q18HNZD has Magic Display, HD Filter, Low refrigerant detection
      LG LS-Q18ANZA has dehumidifier, convertible 4-in-1 cooling, EZ clean filter, low gas detection and cools @ 52°c.

      There is almost no difference between the LG models except for the features. Please have a look at them and select the model according to the requirement. Cooling and Performance wise all the above models are excellent.

      Regarding brand, Both LG and Samsung are Good and provide Quick support in India even in small towns. It is better you opt for the brand that provides quick support at your place.

      • Thank you so much. Is ANZA and GWZA better in features than other LG version. I had searched for review and found the AC listed as 1. But showroom staffs said those are obselete and suggested 2 and 3 for both 1 ton and 1.5.

        • Features depends on personal preference, People living near to cost prefer AC with features like dehumidifier, ocean black protection and people living in a city needs features like dust filter, auto clean. There is no much difference in performance among the models you have mentioned. All the models are 2020 5 Star Inverter with excellent ISEER rating. Showroom guys suggest models according to their stock and profits.

  12. Hi
    Thanks for sharing this info.
    I live in Mumbai on rental basis. One of AC service executive told me the I should go for non-inverter AC as I need to change flat regularly.
    Please suggest.

    • No Major AC brands are not making non-Inverter Air Conditioners now. Inverter Technology is now used in all the major appliances like ACs, Refrigerators, Washing Machines… Any non-Inverter AC is old stock.

  13. Sir,

  14. I want to buy LG LS-Q18YNZA. But on Amazon, I have seen some bad reviews. could you please suggest me this model is really good or not? if not please suggest another one with same features.

    • The Product itself is very good. The bad reviews were about the installation. If LG provides good support at your place, you can go with model.

    • Both are Top Air Conditioner brands. It’s not always about the brand, the individual models of one brand might be better than the other. So, If you can list the model number, we can suggest you the best product.

    • Panasonic is a Japanese brand and their latest 1.5 Ton Wifi AC comes with a Copper condenser and ISEER 4.7 with 5 Star Rating. Also, they are providing 10 year warranty on compressor. Other features include PM 2.5 dust filter, R32 Environment friendly refrigerant. You can go with this model.

  16. Hi

    I am from Chennai. Planning to buy 1.5 ton 5 star Inverter Split AC. Have thought of Bluestar IC518QATU or IC518DATU. Which one is better? Or could you please recommend better model from any brand?

  17. Is it good practice to keep an inverter AC constantly ON even if I am not in the room for few hours in order to limit power consumption?

    • No. You should turn off the Inverter AC if you are leaving the room for few hours. Now, the modern Inverter ACs come with Turbo mode which can cool the room in a few minutes. After that, you can maintain the temperature constantly.

  18. I am staying in Greater Noida West. I did my part of research on split AC. For my bed room I have gone with BlueStar IC518QATU which comes with 1 4 years warranty. For my living room I ordered IC324YATU a 3star inverter bluestar but there was some defect in product so I returned the same. Now when I asked some of my friends they are saying go for non inverter AC for the living room as the room is L shaped with open kitchen. Area is also big (roughly 220 sqft). Now I am confused.
    Can you pls suggest. Which one to buy – Inverter or Non inverter and in either case suggest some good models with 2 ton capacity. Hope the information shared above is sufficient to answer my query.

  19. I stay on ground floor and have a convenient window for fixing the AC. The room is 10×10 and was looking for a 1ton AC. Is it better to go for Split AC or Window AC?

  20. Good technical details mentioned on the article. However please clarify my below doubts:
    (1) When the air passes through indoor unit, it cools down, but it is a mixture of hot & cold air particles. I want to know the actual temperature of R32 Coolant after in expands in the evaporator. I mean up to which value it can go down? -5 deg, -10deg?
    (2) When I set AC to 25deg, still the evaporator temperature reaches to the minimum degree achievable by R32. Then sensor senses temperature of which part to 25deg? Is it room ceiling temp? Is it temperature of air entering into indoor unit? Which part is sensed and compared to 25deg C.
    (3) If the room is 100% Non-ventilated. How many hours it can take single person to consume all Oxygen inside the room, as the AC is only re-circulating the air, no producing any Oxygen.
    (4) Provide some details about refrigerant used in DEEP FREEZERS & their cooling capacity.
    Thanks in advance.

  33. Hi we are at Nagpur,(Summer crosses 42-44 )
    Our usage will be for 5 -6 months around 10 hrs a day.
    we look for Energy Efficient,Powerful AC Machine as we do have Voltage Fluctuations as well.
    Which are options we look for
    What about O General Inverter AC But Cost are high.
    Need opinion.

  34. I’m looking for a inverter AC preferrably 1.5ton with a heating option. Would an AC indicating 30C be able to work as a heater up to 30C? Would you be familiar with what’s available in India or Bangalore?

  35. Hi chaitanya,
    Great work…..
    Suggest me a AC for my sound proof/recording room. Prefarably dust free, as it is packed of rockwool material. Room size around 180sq.ft. Looking for a budgeted one ?

    • If you are living near to the sea, go for the AC Model that comes with Corrosion protection (Bluefin Condenser, micro channel condenser coils). Now, most of the top brands like Hitachi, Blue Star, LG, Daikin, Voltas, Samsung are making AC models that come with corrosion protection for the condenser. Also, there are many models that don’t have protection against corrosion. So, it is better to check out the individual models.

  36. Hi, I live in a seaside apartment and our a/c ‘s seem to last 2-3 years at most. We have had the best luck with Ogeneral in past but am open for a suggestion on best anticorrosive AC, so it will last more than 3 years. I read your reccommendation for microchannel condenser coils but not sure how to figure out which Samsung AC are utilising these.

    Our AC repairman says we should never go for inverter AC. Has the technology improved? From your article it seems to make sense to go for the inverter technology.

    I am looking for a reliable 2 ton that will last by the oceanfront.

    Any reccommendations…

    Thank you for your article.

  37. I want to buy HITACHI kashikoi 5100xplus 1 tone because of company provide 1 1 years warranty on unit

  38. Very Informative article.
    Will certainly look after the aspects mentioned in the article before purchase of A.C.
    I am a senior citizen putting up with my son who is working in private companies and every 2 to 3 years we have to shift to some new locations.
    Will you suggest good sturdy inverter A.C. which needs minimum maintenance with power saving.
    Please also highlight precautions in transportation of the unit.

    Thanks Chaitanya

  39. Good evening
    I’m from Chennai. Currently I’m using a Hitachi 1.5 ton ac which is over 5 years old. I would like to replace this with a new ac.
    My priorities are fast cooling, trouble free functioning and long air flow. I don’t have good experience with Hitachi that I’m using. When it works there is no doubt it’s best in class. But most of the time something or the other repair comes up.

    I would like to get your suggestion on the new Mitsubushi electric 1.5 ton non inverter ac. I went to the showroom and among all the brand’s I fell in love with the airflow this had. The unit is a direct import from Thailand costing roughly 40000 rs. And we have to pay for the copper pipe extra.

    Kindly advice.

  48. Today only I am planning for 5 star 1.5 ton invertor AC..Living on 1 st floor. No construction above.using AC for 8-9 hrs in night and 2 hour during day time. Temp during day time goes upto 43 and evening around 35. Suggest for best service in maharashtra. Its long term investment.
    As I am working in regular transferable job.

  49. You can have a look at Blue Star Air Conditioners (3CNHW18TAFU, 3CNHW18GAFU) Blue Star also uses dual inverter compressor with acoustic jacket on the top and the AC Operation is silent. LG Dual Inverter ACs are also good. Inverter ACs are not very noisy in general. Maintenance cost will be same for both Inverter and non-Inverter AC. The new 2018 Inverter AC models are better than the previous ones and most of the Brands are providing a good warranty.
    Check out the below LG Models (LG-JS-Q18SUXD, LG-JS-Q18NPXA, LG-JS-Q18AUXA, LG-JS-Q18ATXD, LG-JS-Q18AFXD, LG-JS-Q18CPXD)

      • I will go with LG JSQ18 Series 3 Star Dual Inverter AC. LG also Provides Corrosion protection (Gold Fin) and 100% Copper condenser with Ocean Black Protection for durability. The Other two brands are also good. Blue Star also provides Corrosion protection (Blue Fin). Just go for the brand that provides quick support at your location. All the models mentioned above are 2018 models only.

  54. Hi Sankar,
    5 Star Inverter air conditioners are priced a little bit on the higher side of your budget. You can have a look at the below 3 Star Inverter ACs.

Possibly reply soon, planning to order today if not also suggest one model which i can buy immediately…just looking for 30K 3Star either 1.2 or 1.5 copper pls help

  55. Hi Shashank,
    For using 8-9 Hours per day, 3 Star Inverter will be good. Also, you will be using the AC only 4-5 months per year. Please note that higher is the star rating, more will be the energy savings.
    Mitsubishi imports products directly from Japan and they are quite robust products. But, the service provided by them in India is not up to the mark. If they provide better support at your place, then there will be no problem. Hitachi, Daikin, Mitsubishi and Blue Star are the top brands.
    You can have a look at the below 1.5 Ton Models with Copper Condenser.

    , FTKC50RVMV)

  56. Respected Ma’am /Sir
    I stay in Chandigarh: Usage is 2 Hours in the Afternoon and about 7 in the Night:My budget is about Rs 95000.00 for two A.c
    an I have to buy ASAP: ( I want to invest in the Best Ac Normal or Inverter)
    My room Size are 18 Feet By 12 Feet 10 Feet Height. We are staying on the 1st Floor and we have a 2nd floor constructed on top.
    Direct sunlight is from 7 A.M to 11 AM.
    The hottest Temperatures in peak summer months and time of the room are 33 Degree Max…Night Temperatures drop to about 29/30
    I was Informed by a reputed Company representative in their showroom that for my Room Size the Normal 1.5 Ton Ac will have to be installed and NOT the Inverter A.C as the Inverter Ac will not be efficient in cooling. While many other say that Inverter AC is the Technology to be used these days.
    Request your advise to choose the correct AC.
    Thank you

  57. Hi
    I am looking for LG or Bluestar 1 Ton AC. I am mostly inclined for Bluestar RBFU series one. Please let me know your feedback. I am staying in Pune

  58. Hi VS, you have helped my earlier with your article on LED TVs,i finally went for Sony 772e 49inch with triluminous display which is awesome.
    thanks for the wonderful article. I need to buy a 1.5 ton split full copper Inverter AC. my budget is approximately 45000 (can extend up to 10% more).
    I live in Jaipur and plan on using the AC for about 8-9 hours per day for about 4 – 5 months a year. Could you please answer based on above information:
    1) whether I should go for 3 star or 5 star inverter?
    2) the difference in consumption of electricity (monthly) between a 3 star and 5 Star AC given my usage. Is it worth spending those extra 5000 to 7000 for a 5 Star inverter on this usage?
    3) which are the top 3 brands in my budget(please rank)? I want a frank suggestion, I have been thinking about Hitachi or Mitsubishi.
    4) please suggest me a few models from top brands considering the above information and your answers from the above 3 questions.

    thanks a lot in advance.

  59. Dear Sir,

    Please suggest best to buy inverter AC 5 star rated 1.5 ton around 35K ? I am looking for most of features to be incorporated with good service.pls guide.

    • A 5 Star Air Conditioner is more energy efficient than a 3 Star AC. You will be saving more power when you go with the 5 Star model. Also, Inverter Air Conditioners are more energy efficient than non-inverter Split AC. All the 3 Brands you have mentioned are value for money brands. Godrej is an Indian Brand and they have got a lot of popularity for using R290 Refrigerant (Most environment-friendly refrigerant) in their Inverter Air Conditioners. It is better to go with the brand that provides quick support at your place.

  60. Hi
    I am staying in 11th floor living hall 17 x 13 dinning 12 x 10
    bed rooms 14 x 10 what will be capacity i have to chose
    only split Ac possible
    Suggest what capacity I can chose and brand

    thanking you

    • For 17 x 13 room, you need to go for a 2 Ton Air Conditioner. For Dining room 12 x 10, 1 Ton AC will be fine. For Bedrooms 14 x 10, it is better to go with 1.5 Ton Split AC.
      Other than the room dimensions, factors like Sunlight, City you live, furniture and Electronic Appliances in the room also play a major role in selecting the AC Tonnage.
      Always go for the brand that provides good support at your place. If your usage of the AC is high, it is better to go with a 3 Star Inverter AC or more efficient models. Daikin, Hitachi, Mitsubishi, Blue Star, Voltas, LG, Samsung, O General, Carrier are top AC brands in India. Recently Godrej, Sansui, Lloyd are also gaining popularity due to competitive pricing.

    • As you are living near to the sea, it will be better to go with an AC that comes with Anti Corrosion coating for the condenser. If the Ceiling of your room or west, south walls of the room gets direct sunlight, it will be better to go with 1.5 Ton Split AC.
      You can have a look at the below models.
      LG JS-Q18 Series (Flipkart Link – http://fkrt.it/p8NXVLuuuN) (Amazon link – http://amzn.to/2F2s7ek)
      Samsung AR18NV3HFTR (Amazon Link – http://amzn.to/2FtYHUq) (Flipkart Link – http://fkrt.it/3wano2NNNN)
      Blue Star ACs are also good. They provide anti-corrosion protection in the form of Blue Fin Condenser. (3CNHW18CAF/U, 5CNHW18PAFU, 5CNHW18PAFUSMRT, 5HW18SBTU, 3HNHW17RBFU, HNHW18CBFU)
