Best air conditioners in India 2022 – Buying Guide And Tips

Best air conditioners in India – Buying Guide

Various Types of Air Conditioners

Split ACs

Split ACs are the most popular air conditioners because they are efficient and offer a lot more convenience. The compressor is installed outside the room, while the evaporator stays in the room. You can find these air conditioners in 1 ton, 1.5 ton, and 2 ton variants.

Advantages Of Split ACs

  • They consume far less energy than other AC types.
  • They perform quietly since the compressor unit, which makes the most noise, is installed outside.
  • Split ACs have very advanced and versatile features.
  • They’re better at cooling without leaving any hotspots.
  • Longer lifespan due to their efficient cooling mechanism.

Disadvantages Of Split ACs

  • They’re more expensive than other ACs.
  • Harder to install.
  • The compressor unit still makes significant noise.


Window ACs

Window ACs are a popular choice because they are less expensive than Split ACs and can be installed more easily. However, they are not as efficient as Split ACs and can create a lot of noise.

Advantages Of Window ACs

  • More affordable pricing.
  • Easier installation.
  • No need for extra outdoor space.
  • No need for extra ductwork.
  • They offer more widespread and thorough cooling.
  • Ideal for medium rooms.

Disadvantages Of Window ACs

  • Most models are incredibly noisy.
  • They break down more often and need to be maintained more frequently.
  • Shorter lifespan compared to Split ACs.

Recommended Reading: Split AC vs Window AC – Which one should you buy?


Portable ACs

Portable ACs are a good option if you want an air conditioner but don’t want it to be permanently attached to the wall. Portable ACs are more efficient than air coolers and use a compressor and coolant to cool. However, they have their own drawbacks, one of the most notable being less efficient cooling.

Advantages Of Portable ACs

  • They’re portable and can be moved around easily.
  • Easy to install, as it’s only a single unit.
  • They’re the least expensive compared to larger ACs.
  • Small and space-efficient.
  • Easy to move across homes.
  • A lot of models offer dehumidification features.

Disadvantages Of Portable ACs

  • They can’t cool large rooms.
  • They make a lot of noise compared to other portable cooling options.
  • Hard to pick the right capacity for a specific room.


Different Types Of Compressors

The compressor is the most vital component of any AC, and in fact, the AC’s entire performance depends on the compressor. So, you should understand how it works to purchase an AC that can satisfy you.

The compressor’s job is to compress refrigerator gas into a high-pressure liquid. The liquid then passes through the condenser coils, which take out the heat from the liquid and release it into the surroundings as cool air.

The expansion valve reduces the pressure in the system and converts the liquid into gas. This gas is then passed through the evaporator coils, which absorb the heat from the room and cool the room.

There are two types of compressors you’ll see in most air conditioners. Let’s have a closer look at them.

Reciprocating Compressor

Reciprocating compressors use a mechanism similar to that of a car engine. In other words, they work on the concept of cylinders and pistons. The piston moves in a back and forth motion, compressing and releasing the gas.

Pros Of Reciprocating Compressor

  • They’re easy to maintain, as the piston and shaft mechanism is common and easy to disassemble.
  • Several piston and cylinder arrangements can be set within the compressor, allowing the production of extremely high pressure.

Cons Of Reciprocating Compressor

  • The noise and vibration are higher with these compressors because of the moving mechanical elements inside.
  • Expelled hot air has really high temperatures.


Rotary Compressors

Rotary compressors consist of two rotors. These rotors rotate in directions opposite of each other. The refrigerant gas is compressed as it flows between them.

Pros Of Rotary Compressors

  • Due to the fewer mechanical moving parts, these compressors make much less noise than their reciprocating counterparts.
  • These compressors can work well under many power ranges and pressures, making them a good option for commercial use.

Cons Of Rotary Compressors

  • They’re comparatively more expensive.
  • They have a minimum use quota to prevent corrosion, which makes them less ideal for home usage, as ACs are used less frequently in such places.

Both compressors have their own benefits. If you’d like to see a detailed comparison between them, you can take a look at Reciprocating vs Rotary Compressor in AC: Know the Difference.


Things to consider before buying the Best Air Conditioners


1. AC size and capacity

Choosing the right size is very important when buying an AC. An oversized AC will cool down the room very quickly. But in that case, the power consumption will be unnecessarily much higher.

On the other hand, if you select a size that is less than what is needed, the room will not cool down properly. There will be extra pressure on the compressor. Power consumption will also be much higher. You need to select AC capacity depending on your room size.

While you measure the size of the room, there are also a few more things to consider. To begin with, the AC will interact with the room differently based on where you live. The temperature varies according to the location. When the temperature in Delhi rises to 45° C during the hot summer, the temperature in Kolkata is around 37° C at the same time. If you live in a place where the temperature rises too high in the summer, then you should select a high capacity AC.

The location of the room where you want to install the AC in is also significant. The change will be small, but still noticeable. If your room is located on the top floor or if there is direct sunlight on the roof, then the room will be much hotter. Similarly, if direct sunlight is applied to any wall of a room, the room will be much hot. In this case, you should select a high capacity AC.

Now, let’s see what the AC capacity should look like depending on the room size.

Room sizeAC capacity
Upto 80 Sq Ft.0.75 ton.
80 to 120 Sq Ft.1 ton.
120 to 180 Sq Ft.1.5 ton.
180 to 300 Sq Ft.2 ton.


2. Power Consumption – Star Ratings, EER, CoP, ISEER

When purchasing an AC, it is important to look at the different ratings, such as the BEE rating, EER, CoP, and ISEER. The BEE rating is given with stars, and more stars mean more energy efficiency. However, don’t just go for the AC with the highest star rating. Look at other ratings, too, if you want to know the AC’s true efficiency.

The higher the EER (Energy Efficiency Ratio) rating, the more heat an air conditioner can remove per hour while using less electricity. The CoP (Coefficient of Performance) tells you how much power input is converted into cooling output; an AC is more efficient if it has a high CoP.

Lastly, ISEER (Indian Seasonal Energy Efficiency Ratio) measures an AC’s efficiency over a year, taking into account different temperatures. The higher the ISEER is, the more power savings and performance you’ll get.


3. Inverter Mechanism

An inverter AC is an AC that has a built-in inverter that varies the compressor’s speed in order to maintain a set temperature. This variation in speed helps conserve power and increases durability. Most of the best ACs in India usually come with an inverter equipped.

When you turn on a Non-Inverter AC, the compressor starts at full capacity and runs until the room’s air has cooled down. If the room starts getting warmer, it’ll turn on again at the same capacity. This can be inefficient because the compressor is always running at full power instead of dynamically increasing and decreasing as needed.

Inverter ACs are more power-efficient than standard ACs – they’ll continue running at low capacity to maintain the cool temperature rather than turning off completely. Investing in the best Inverter AC can save you money in the long run, as the compressor consumes less electricity.

You can also consider looking into Dual Inverter ACs, which can provide many significant benefits.


4. Coils

The coil is an important part of an AC unit because it helps the refrigerant move from one place to another. There are two types of coils- copper coils and aluminium coils. The type of coil you choose depends on your needs and preferences.

Copper coils are a great choice for those looking for durability and easy maintenance. They cool better than other coils, but they’re more expensive and not very flexible.

Aluminium coils are cheaper and more flexible than copper coils, but they cannot provide as much cooling. They also are not as durable as copper coils.


5. Fins

Fins can improve the performance of an air conditioner by increasing its durability and efficiency. There are two types of fins- Gold Fins and Blue Fins. Gold ones last longer and are more versatile.

Most of the Best ACs in India use Gold Fin condenser coils. Blue Fin ones are decent, often being used in mid-range ACs. However, they’re less durable and efficient.


6. Coolant Or Refrigerant

The refrigerant is a vital factor to consider when purchasing an air conditioner. To put it briefly, a refrigerant is a substance used in cooling systems like air conditioners. It helps to remove the heat from inside your room and make the air cooler.

The best ACs in India use R410A and R32 refrigerants. They are environment-friendly and do not harm the ozone layer.


7. Air filters

Unless you have something in your home that cleans out the air, there’s a chance that air has traces of pollutants in it. These pollutants can end up making you sick. Having a good AC can help in this regard, as they have air filters installed which increase the quality of the air. The best ACs can clean out bacteria, dust, pollens and other pollutants from the air, making it healthy to breathe.

It would help if you went for air conditioners with more than one filter, as there won’t be much of an increase in price. Just make sure you clean the filters out every once in a while, as they can affect the AC’s efficiency.


8. Cooling Performance

Various factors determine the cooling performance. That includes the weather, the location of the house and room, the material of the condenser coils etc. These are just some of the most important things that affect ACs cooling performance.

AC’s type and features also affect the quality of the cooling. If you get an AC after considering these factors, you should have excellent cooling performance. Just make sure your room stays airtight when the AC is running. If you want really fast cooling, make sure the AC has some kind of turbo mode specifically designed to speed up cooling.

However, to keep up the performance, you must maintain the AC properly, and if you live in a coastal area, you should make sure the AC has a Gold Fin condenser, which will help keep corrosion down.


9. Dehumidification

Humidity can be a huge problem as it can make you feel uncomfortable and harm your health. It can even affect your building. In fact, even air-conditioned spaces have high humidity levels.

Fortunately, brands have started to add a dehumidification mechanism to the most recent ACs. You can use the mechanism by tuning on the Dry Mode, which removes the moisture in the air and makes the humidity lower and more bearable.


10. Noise Level

ACs generally produce a lot of noise, so if you don’t want to be bothered by constant sounds from your air conditioner, you should make sure that the AC has good quality components. For instance, a compressor and motor can significantly impact noise production. There’s also an indication of the noise level somewhere on the box or in the product specifications.

You should get the best Split AC for the least amount of noise as it keeps the most noise-making components outside of the room.


11. Control options

Most ACs allow the user a lot of control over their speed. Having such control allows you to make the cooling feel more comfortable and save on electricity bills. To get the most out of an AC when it comes to the amount of control, get a Smart AC with an Inverter.


12. Timer

A timer is a handy feature. You can use it during sleep when you can’t control the AC by yourself. You can just set the timer to a certain amount of time before bedtime. Afterwards, the AC will automatically turn itself off once it reaches that timer.


13. Brand

Not only is your AC going to be a large purchase, but it’s also going to be frequently running, which might cause it to run into problems. As such, if you get an AC from a good brand, you’ll have the assurance of good customer service. Besides, you won’t be running into many problems with such an AC anyway, as most ACs from good brands are very durable.


14. Price

An AC itself is an expensive purchase, as it has a lot of complicated mechanisms and expensive components. Don’t buy an AC merely based on the initial price. If you do so, you might be at a loss if the AC wastes too much power and runs into various problems. The best air conditioners might seem expensive, but that’s only about the initial price; they save you a lot of money and trouble in the long run.

15. Warranty

It’s generally easy to fix AC problems on your own. However, sometimes the AC might run into huge problems and stop working completely. Such might not occur often, but if it does, it will cost you a lot to get it fixed unless you have a warranty. So make sure the warranty of your purchase will last a significantly long time.

Best Air Conditioners (AC) in India – Frequently asked questions

Can I buy an AC online?

You can. There are websites like Amazon that emphasize customer satisfaction and safety. You will find the ACs at discounted prices, and refunds are available if the products are defective.

To sum it up, there’s absolutely no harm in purchasing air conditioners online, especially from reputed eCommerce platforms. You can also look up reviews on those sites, making it easier for you to buy the best air conditioner for yourself.

Do I need a stabilizer for the air conditioner?

Each AC has a voltage operating limit. If you look at the printing on the AC label, you’ll find the range. We advise you to check if the area you live in has voltage fluctuations beyond the limits of your AC.

In the case that are such voltage fluctuations, it’d be best for you to invest in a stabilizer for your AC. It will protect your air conditioner from voltage fluctuations. After all, it’s better to be safe than sorry. A stabilizer will cost much less than your AC. Start using one so that you no longer have to worry about voltage fluctuations.

What is a Dual Inverter AC?

Dual Inverter Compressors are present in some of LG’s ACs. As the name suggests, these provide twice the efficiency over a single inverter AC.

With this technology, the AC creates far less noise and provides higher quality cooling. Despite cooling faster, it also ensures that the compressors run at low speeds most of the time. Therefore, you get to save a lot of electricity.

Which brand should I buy?

There is a large number of AC brands within the market. Picking them is a matter of personal preference. However, our guide will help you with what to look for when you’re about to buy an AC. Keep an eye out for the energy efficiency of the AC and how eco-friendly it is. Certain brands also have some distinctive features that might suit your needs better than others.

Make sure that to get the right balance between costs and the actual value. Once you consider all three aspects, you should go for inverter AC units, which are the most efficient. If you prefer international brands, then Japanese brands like Daikin and Panasonic, or brands like LG and Whirlpool are a good idea. Suppose you want a brand that focuses mainly on Indian conditions. In that case, Voltas and Godrej are some great choices.

Is it OK to get an AC with an Aluminium Condenser?

The most common metals used to manufacture condenser tubes are Copper and Aluminium. Both of these metals have their own advantages and disadvantages. Copper has a higher heat transfer coefficient compared to Aluminium.

On the other hand, Aluminium is far more malleable and relatively inexpensive. However, they require higher maintenance. You can still go for Aluminium, but Copper is the most widely accepted choice. Aluminium condensers aren’t bad either.

What are the Blue Fins and Gold Fins?

You might’ve heard those terms when you were looking around to get an AC. Dealing with corrosion is their primary objective. In fact, corrosion is the main enemy of air conditioners. Eventually, condenser tubes suffer from corrosion and need to be replaced or repaired.

To tackle this problem, manufacturers use Blue Fin or Gold Fin technology, where they paint condenser tubes with special anti-corrosive paint. As a result, the life of the AC gets significant improvement. The only distinction between these two technologies is that Gold Fins do not rust easily, further enhancing AC durability.

Although, this technology costs more than its Blue Fin counterpart. Both of them have their own merits and demerits. It is upto you to choose by considering all aspects.

What is a dehumidifier in an AC?

Humidity can make you feel lethargic. Especially so during warm summer days and nights. Even air-conditioned homes have a high humidity level sometimes. Not only will the humidity make you feel uncomfortable, but it will also harm your health and even your building.

For the user’s protection, some air conditioning units have dehumidifiers, which remove the moisture in the air. As a result, the humidity is lower and on a more comfortable level.

Which condenser is better for coastal areas?

Corrosion will be the primary concern when you’re in a coastal area and want to make your AC last a long time. For instance, Copper is an excellent material for manufacturing condenser coils. However, it is also the only metal that falls prey to formicary corrosion.

In fact, this corrosion isn’t even visible to the naked eye. In coastal areas, the chances of this corrosion are much higher with the excess humidity. Sometimes, with AC units having copper coils and aluminium fins, galvanic corrosion can occur. As such, it’s best to have a single metal for the condenser tubes and fins.

Microchannel condenser coils, along with Blue Fin or Gold Fin coatings on the condenser coils are the best for use in coastal regions.

Can the AC keep the air clean?

We know that indoor air contains a lot of dust. This dust and bacteria can cause breathing problems. To get rid of this dust, you typically keep the windows and doors open to ensure air circulation. However, operating an AC means you have to close those windows and doors. As a result, you’d be inhaling the same air.

The AC units have dust and bacterial filters which prevent these particles from recirculating. The newest ACs also feature air purifiers. Therefore, you will have clean and pure air to breathe. You will see evidence of the AC helping in this regard when you remove the filters to clean them.

What is the Mosquito Away technology in some ACs?

The Mosquito Away technology is available in most of LG’s newest ACs. This technology uses ultrasonic sound to keep away mosquitoes. The AC units produce this sound, which is beyond the hearing power of humans. However, it works on mosquitoes and gets them away. This technology is available in most of LG’s other products as well, like their TVs and phones.
