Best Inverter ACs in India

Inverter ACs | Check on Amazon | September 2021

Inverter air conditioners are more effective and use less energy than normal AC.

An AC inverter increases its speed according to the thermal load of the room. Unlike normal split AC, inverter air conditioners have speed motors that adjust their speed according to the requirements.

So obviously they consume 30-40% less power.According to the Office of Energy Efficiency, a BEE 3 Star rating AC inverter is 7% more energy efficient than a typical BEE split AC.

Note that the inverter technology is only available for split ACs.

With normal air conditioning, there will be slight fluctuations whenever the compressor is on, and when the compressor works, the room cools down, and when it is turned off, the room may become slightly warmer.

But, this is not the case with best inverter AC, when you set the temperature, after a while the temperature will be almost constant and you don’t even know if the compressor is working or not.

AC inverters are the best way to beat heat during summers in India. Because they consume 30 to 40% less energy than normal AC.

The inverter air conditioner runs continuously by consuming less energy to maintain a uniform temperature throughout the night.

Whereas regular air conditioners turn the compressor on and off to maintain the desired temperature in the room. Whenever it restarts, it consumes 3 times more energy, which results in higher electricity bills.

We have spent a lot of time in this article giving guidelines and research on choosing AC inverter. We recommend considering the 3 main factors below to make an informed decision.

Let’s look at the main parts of split AC

The compressor

The compressor is the heart and soul of the air conditioner. In a split air conditioner, this component is located in the outdoor unit. The main function of the compressor is to ensure the circulation of refrigerant between the condenser and the evaporator coil. He does this in a closed circuit.

Condenser coil

The coil is a network of tubes filled with refrigerant (usually freon). The condenser coil has the responsibility of removing the heat from the hot refrigerant gas and cooling it back to liquid form. The coils allow the absorbed heat to escape from the outside air. These condenser coils are part of the external unit.


Fans have the function of extracting hot air from the condenser coil and circulating heat. They are also located in the outdoor unit.

Evaporator coil

These coils work opposite to the condenser coil. These coils have a refrigerant to remove heat and moisture from the air, so the refrigerant evaporates into gaseous form. You will find these evaporator coils in the indoor unit.

Air filters

Air filters work to trap dust, pollen, and other particles in the air and prevent them from entering the air conditioning system. These filters play an important role in ensuring air quality inside the room.

Drainage system

Naturally, you will find this system outside. Water is an important by-product of the condensation process.

You must remove this water from the system. It is important to keep this system in proper working order. Any clogging of drain pipes can affect the operation of your air conditioner.

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

Now that you have seen the different parts of a split air conditioner, you also need to understand how it works. You can divide this system into four main parts.

1. The first stage is the compression of the gas and the conversion into a hot liquid at high pressure.

2. The condensation of this liquid is the second stage of the process. The process occurs when hot liquid flows through the condenser coil. The heat escapes outside and the liquid cools. However, the liquid is still under high pressure.

3. Expansion valve has the function of converting high pressure liquid to low pressure liquid.

4. The last step involves passing this low pressure liquid through the evaporator coil where you can see the absorption of heat from the room. This heat converts the liquid into a gas. Now, as the heat is absorbed, you get a cooling effect inside the room.

The whole process keeps repeating itself.

In normal air conditioning, you will find that the compressor runs at full capacity and ensures that the room temperature reaches the desired level. Doing so makes the thermostat identical and turns off the compressor. The fan takes over and allows cool air to circulate inside the room.

As room temperature rises, the thermostat sends a signal to restart the compressor. This process continues until you turn off your AC.

Difference between an best Inverter AC and a non- inverter AC?

This is a good question. You can see how differences develop as you delve into the article.

The basic difference between the two is that in an AC inverter the compressor operates continuously, while it is on and off in AC without an inverter.

AC drives with an inverter operate at variable speeds, while AC drives at a fixed speed without an inverter.

This allows best Inverter AC to adjust their tonnage according to the size of the room. Normal air conditioning units do not have this capability.

These are the basic differences. We will go into details of individual differences at the appropriate time.

To understand the difference between a normal AC and an inverter AC, you must have a prior understanding of how these ACs work. Let’s see the same in the following paragraphs.

AC Inverters vs BEE 5 Star Normal AC

Speed ​​/ tonnage

Normal air conditioning units operate at fixed speeds and tonnage levels, while inverter air conditioning units have the ability to operate at different speeds and tonnage. This is one of the main distinguishing features.

Automatic adjustment

Inverter air conditioning units have the ability to adjust according to room temperature. Common air conditioning units lack this capability.

Power consumption

Statistics show that AC inverter units consume much less power than normal units. In fact, an AC with a 3-star BEE inverter is 7% more efficient than an AC with a 5-star inverter.


An inverter AC can certainly cost more than a normal 5 star BEE AC. However, you can make up for this by saving on your electricity usage.

Power Consumption: AC Inverters vs. AC Inverters

It has best Inverter AC of various capacities and efficiency ratings. In the normal course, the 5-star rating is considered the most energy efficient system.

Typically, people install air conditioning units with a capacity of at least 1.5 tons. Therefore, we will compare the power consumption of a 5-star non-inverter AC to a 3-star inverter AC. We will also look at comparing 5-star AC inverter to understand the benefits to the consumer.

Annual power consumption (units or 1600 hours) BEE data

According to BEE data, a 5-star AC with a 1.5-ton capacity without an inverter consumes 1,130 units of energy in 1,600 hours.

The corresponding figure for a 3-star AC inverter is 1077 units at 1600 hours. As you opt for high efficiency inverter AC, power consumption is reduced to 972 units and 815 units for 4-star and 5-star AC inverter respectively.

This is sufficient evidence that AC inverters can help save considerable energy.

How does an AC inverter save energy?

Normal best Inverter AC cools the room slightly from the thermostat setting and turns off the compressor until the room is warm enough.

When he feels the heat, he starts the compressor again. This process of turning the compressor on and off consumes more energy.

Inverter air-conditioning units, on the other hand, run at twice the speed of the room’s rapid cooling capacity and then slow down the compressor motor significantly to maintain cooling at all times.

As the temperature inside the room rises, it releases more energy, thus controlling the use of electricity everywhere.

We will look at a small example to prove this fact.

The 1.5 ton AC inverter will initially run at 150% speed to cool the room faster. In doing so, reduce the speed to about 10% to maintain the required temperature. This variable speed and tonnage can result in energy savings. The compressor does not turn on and off at regular intervals, so it also saves energy.

Star rating for ac inverter

Like any other electrical or electronic appliance, it also has a star rating for inverter air conditioners. Ratings depend on various factors such as power consumption, efficiency etc.

Buying Guide: Everything you need to know about Inverter ACs

How ac inverters work

In recent years, air condition has come with inverter technology. With the help of this new technology, AC will control the speed of the compressor and control the temperature continuously.

Due to the presence of the inverter, these machines can run silently, consume less power and provide a better cooling environment. The main advantage of using AC inverter compared to traditional AC is that they consume 50% less power.

Difference between inverting and non-inverting AC

AC Inverter vs Non-AC Inverter

When choosing the best air conditioner for home or office, AC with inverter or AC inverter is the best option. Millions of air-conditioning units are sold annually and, on average, 10% of household utility bills are for refrigeration units only.

Ac inverter non ac inverter

The AC inverter has a compressor motor and variable speed. The compressor is on all the time. Non-inverters have a fixed compressor and the speed is fixed. The compressor turns on and off.

To control the AC inverter refrigerant flow, adjust the speed of the compressor. Based on a room temperature, AC without an inverter delivers a fixed amount of power.

In inverter AC, cooling and heating is an automatic process. The AC is turned on and off without an inverter, so you can keep the temperature low within the set range around room temperature, making it environmentally friendly.

Best Inverter AC are slightly more expensive than non-AC inverters. AC-inverters are priced lower than AC inverters. However, installing an AC unit without an inverter is likely to cost more than an AC with an inverter.

Different types of air conditioners

According to their work characteristics, ACs are divided into various categories. We have mentioned them below for your information. Read them carefully to make the right decision.

1. Turn off the air conditioner

AC Window

It was one of the most common ACs seen in Indian homes. These air conditioners have the ability to cool one room at a time.

If you have a big house, you may have to install them in every room you want to cool down. Although they are not inexpensive, they are still a popular option for people living in apartments and small houses.

These best Inverter AC have components that are similar to a central air conditioner. Some of these components are evaporator coils, fans, compressors, and coolers. However, they are kept together in a small unit that can be mounted on a window.

Window ACs are available in various sizes suitable for small or large rooms. The size of the air conditioner directly affects the generation of cold air.

However, the cooling capacity of a window air conditioner is limited due to its small size and static location.


Suitable for cooling individual areas or individual rooms.

Central air conditioning systems are less expensive than installing.

The new residence is easy to uninstall and relocate.

Additional conduits are not required.


Compared to other air conditioning systems, they are quite noisy.

As installed in the window, it can hide the view outside.

It should be installed near a suitable electrical outlet.

2. Split Air Conditioner

Split air conditioning

ACs of this type have become very popular in recent years. The split conditioner consists of an indoor unit and an outdoor unit.

The outdoor unit will be installed on the side wall. This unit consists of a condenser coil, a compressor and a capillary tube (or expansion oil).

The indoor unit consists of a cooling coil, an air filter and a long fan. Outdoor and indoor units are connected via conduits that carry refrigerant lines, drain pipes, and electricity.


Since the main components that make noise (compressors and fans that cool the compressor) are placed in the external unit, the split air conditioner is silent.

Window air conditioning installation is limited, but split air conditioning can be installed anywhere. It does not require large holes in the walls or expensive condes for installation. In addition, the outdoor compressor unit can be installed far away from the unit. They are also easy to clean and maintain.

Things to keep in mind when buying AC inverter

Buying an air conditioner is not a small investment, you have to make sure that the product you choose suits your needs. Here are some important factors that help you make the right choice.

1. Capacity

When purchasing an AC inverter, the first thing to consider is its cooling capacity. It is usually measured in tons. The “ton” measure refers to the amount of heat per hour per AC.

The basic rule you need to consider when checking cooling capacity is: the higher the ton, the higher the cooling capacity, meaning that AC can cool a large space quickly.

To find the right capacity for your needs, the first thing to do is to measure the room in which you will install the air conditioner.

Based on this information, you can select an air conditioner with proper cooling capacity. You can check the capacity range of the air conditioner in your instruction manual or in the product specifications.

Here is a table that represents the size of the room and its adequate capacity. Sometimes the representation of tonnage below can vary depending on factors such as usage, number of people in the room, and number of devices.

2. Power consumption and star rating

Almost all inverter best Inverter AC in India come with a star rating, representing the energy consumption and energy efficiency of the product.

EER stands for Energy Efficiency Rating and ISEER stands for Seasonal Energy Efficiency Index of India. These parameters directly affect the star rating of the inverter air conditioner.

So whenever you are checking these ratings, remember that the higher the stars, the more efficient the air conditioner will be. And the same goes for ISEER. This means that: ACs with higher star ratings will consume less power during operation.

If you want to reduce your monthly electricity bill, choose AC inverter with higher star rating.

3. Compressor

The compressor is the most important component of an best Inverter AC. Therefore, you need to be more careful while analyzing this factor.

Before learning the different types of compressors and choosing one, we will first understand the role of a compressor in AC.

The working principle of the compressor is: compress the air conditioning refrigerant gas into the high pressure liquid at high temperature.

The high pressure liquid will then pass through the condenser coil. At this stage, it will lose heat and come out of the air conditioner as cold air.

Now, we will discuss two different types of compressors: reciprocating and rotary. Please read the following description to understand which is best for you.

Reciprocating compressor

This type of compressor is actually similar to a car engine. Cylinder and piston are included. Piston components move continuously and backward to generate compression and to expel gas.

This compressor is very easy to maintain and works efficiently even at high temperatures. But it generates noise and the expelled air will also have a higher temperature.

Rotary compressor

Most new air conditioners have a rotary compressor. As the name suggests, this compressor uses rotors, which are carefully arranged with less space between them.

These rotors move in the opposite direction to expel high-pressure air. Since this process does not generate noise, it is suitable for industries and large offices.

And also, the air coming out of the compressor will be at a lower temperature. But compared to reciprocating compressors, rotary compressors are expensive and require high maintenance and usage to achieve optimal results.

4. Coil

Condensers in best Inverter AC use coils to cool the air. In addition, coils are also responsible for improving efficiency and controlling energy consumption.

The coils are made of copper or aluminum. These two types are very popular because they can improve efficiency and control energy consumption.

Let us understand through a detailed description of these two types which of your requirements is the best.

Copper coil

Compared to other coils, the copper coil is easier to maintain and lasts longer. This is the most preferred option, as they cool the air in less time. Due to their anticorrosive properties, copper coils are best suited for coastal and high humidity areas.

5. Cooling Speed

Choose an best Inverter AC with several cooling speed settings. Never go for an inverter air conditioner that only comes with a cooling rate, as you will not be able to adjust the temperature according to the temperature outside.

6. Dehumidification

Almost all air conditioners have some ability to control humidity in addition to cooling indoor air.Some inverter air conditioners come with different dehumidification settings, which is useful in areas with high humidity levels.

7. Air Quality

When using air conditioning, indoor air quality is one of the important things to consider. That is why buy an inverter with a good filter to maintain air quality inside the room. Having a good filter not only provides clean air, but also improves the cooling performance and energy efficiency of the air conditioner, which can be hindered due to dust buildup on the evaporator coil.

8. Refrigerator

Usually air conditioners and refrigerators have refrigerants. It is a core component of any device with freezing technology. Refrigerant can be used as a gas, liquid, or liquid substance. In an air conditioner, it is usually present within the condenser coil.

Its operating principle is to absorb the heat present in the room and to expel it from the outside environment. If the refrigerator works efficiently, the heat will quickly expel and the room cools rapidly.

When turning on the air conditioner, the first refrigerant or refrigerant (present in the gas format) will go through the compressor.

At high pressure, the refrigerant gas transforms into a liquid and passes through the coil. Now as the temperature decreases, the liquid refrigerant turns back into gas.

Finally, the air conditioner will remove the heat and release the cool air.

There are many different types of refrigerators. We have mentioned them below for your information …

Chlorofluorocarbons (CFCs)

This is sometimes called R12 refrigerant. It is one of the first refrigerants used in an air conditioner. They work efficiently but reduce ozone content in the atmosphere. However, only some air conditioners use this refrigerant.

Hydrochlorofluorocarbons (HCFC)

This is commonly referred to as R22. Due to environmental concerns, the R12 has been replaced with the R22.

It is a commonly used refrigerant in modern air conditioners. Although it is not completely environmentally friendly, it may be replaced by another refrigerant in the near future.


It is very similar to the refrigerant R22. Furthermore, it is environmentally friendly and does not affect the ozone layer.

This is why most manufacturers in India are considering using this refrigerant. In addition, it provides maximum efficiency without causing harmful effects on the environment.

Hydrocarbons (HC)

This refrigerant, which is the future of refrigerants, will be used in air conditioners. It is the most environmentally friendly refrigerant available.

This is why most companies are trying to use this refrigerant for their air conditioners. Currently, this refrigerant is used in most inverted air conditioners, ensuring that this refrigerant is brought to the next air conditioner.


The capacity and efficiency ratings of air conditioners available in the Indian market vary. In general, an best Inverter ACwith 5 stars is considered the most energy efficient device.

Below we have provided a table representing the AC power consumption with different capacity and their respective star ratings.

0.75 Ton 1 Ton 1.5 Ton 2 Ton
3*Non Inverter 627 828 1235 1548
3* Inverter AC 550 726 1077 1344
4* Inverter AC 499 658 972 1208
5* Non Inverter AC 576 760 1130 1412
5*Inverter AC 421 557 815 1005

A 5-star AC without a 1.5-ton capacity inverter consumes 1,130 units of energy in 1,600 hours, according to BEE data.

In general, a 3-star inverter air conditioner consumes 1077 units in 1600 hours. When it comes to high efficiency like 4 and 5 star AC inverter, the consumption drops to 972 units and 815 units respectively. This suggests that inverter air conditioners can save more energy.

Some tips to maintain air conditioning properly

We do not usually best Inverter AC in cold and rainy seasons. During this time, the filters present in the AC will accumulate with dirt.

This can affect the airflow of the equipment and make it harder, resulting in higher energy consumption. Therefore, before reusing the air conditioner during summer, we recommend cleaning the filter properly.

To increase the efficiency of the best Inverter AC, we recommend cleaning the condensing unit regularly. It is also recommended to replace the coolant with a new one at regular intervals.

Electronic devices such as laptops, televisions, stereos, and computers give too much heat to the work mode. If you have any in their room, be sure to turn them off when not in use.

Also, you should never place any electronic device near the air conditioning thermostat. As this will directly affect the operation of the thermostat. This, in turn, will make the work of the condenser even more difficult.

When using an air conditioner, room insulation should be optimal. Doors and windows are the main areas where air can escape easily.

Therefore, you need to make sure that there are no gaps for the air to escape. It is good to have rugs and rugs in the room as they prevent air from escaping under the doors.

If you want to save electricity, it is better to keep the temperature between 24-25 ° C.

A professional air conditioning checkup is a good thing to do. The evaporator coil and condenser coil will be cleaned. Sometimes dust accumulates in the dust of the coil’s wings, which can add more charge to the condensing unit.

When the air conditioner is not in use (during the winter months), we recommend covering the compressor. This allows the air conditioner to be in perfect working order for the coming summer.

Rear drain is an important part of the air conditioner because it drains out the water. If water collects inside, it will damage the coils and may even cause electric shorts.

Frequently Asked Question Answer

1. What is the problem with buying an AC without an inverter?

Just because an AC with an inverter costs less than an AC without an inverter does not mean that you buy it.

The initial cost will be cheaper by a few thousand, but in the long run, you will have to spend thousands and thousands on the energy bill.

Non-inverter AC has a fixed speed compressor and is therefore less energy efficient. In other words, they consume more electricity or electricity and hence the energy bill will be higher than AC inverters.

Second, non-inverting ACs always cool the room very much, meaning that if you set the temperature at 25 ° C, the final output will be around 22–23, which can be inconvenient for many people.

This is because the fixed speed compressor is designed for maximum heat load. Despite the thermostat shutting down the compressor at 25 ° C, the refrigerant manages to absorb heat from the air in the room and convert it into gas.

Finally, non-inverter ACs are becoming increasingly obsolete. Therefore, you should buy them at your own risk as spare parts may not be available in the future.

Air conditioners require annual maintenance and sometimes have some parts that you need to replace in the event of damage in any way. In such case, if the spare part is not available, then you need to buy a new air conditioner. This is why it is always best to buy the latest model, and most latest AC models have inverter technology.

2. What is dual inverter AC?

A dual best Inverter AC is a new addition to the market and an improvement over the normal inverter AC. It comes with dual rotary motors and hence its name.

The product has a wider rotation frequency because it is more efficient in its performance. The cooling will be faster and there will be less noise.

Not only this, there is going to be better savings on energy bills and therefore buying it is a more profitable product.

A normal best Inverter AC works best when the outside temperature is below 46 ° C. But for dual inverter ACs, this temperature range is up to 52 ° C.

In addition, it works just like a normal AC inverter by regulating the speed of the compressor. If your area sees extreme temperatures in summer and you are a heavy AC user, opt for dual inverter AC. You can take a look at our best air conditioner in the list above.

3. Is it okay to wear perfume with air conditioning?

The wonderful smell of perfume can create a good atmosphere in the room. However, you should be careful while using it, as some people may be allergic to them.

If you want to eliminate bad odors, we recommend that you open the windows and doors for a while before turning on the air conditioning.

Fresh air will eliminate the bad smell present in the room. So you don’t have to wear perfume to deal with the fragrance.

However, if you still want a nice scent in the room, go for air fresheners. This does not affect the performance of the air conditioner and ensures that the room smells good. We also recommend cleaning the air conditioner regularly.

4. What is the price range of inverter air conditioner?

The cost of an best Inverter AC depends on its capacity and other characteristics. The 1 ton inverter air conditioner comes under Rs. 20,000 to Rs. 35,000.

The 2 ton inverter air conditioner is below Rs. 35,000 to Rs. 60,000 Rs. And 1.5 ton inverter air conditioner from Rs 30,000 to Rs. 45,000 Rs. Some models are expensive and others are less expensive in the same capacity range, as costs also vary based on energy efficiency ratings.

5. Are window ACs with inverter technology available?

Inverter technology is mainly available for split ACs. However, brands such as LG and Voltas have released a handful of models, with the compressor in window AC having inverter technology.

6. What is the ISEER classification for air conditioners?

The Bureau of Energy Efficiency (BEE) is responsible for awarding AC star ratings to help customers identify the energy efficiency of various AC models.

In 2018, BEE introduced a new star rating label called India Seasonal Energy Efficiency Index or ISEER. This is an improvement over the previous classification system as it takes into account different climatic zones in India, variation in temperature range and more.


You have seen the concept of best Inverter AC. Now, you also know the advantages of using inverter technology.

However, it is of the utmost importance to ensure that you maintain your air conditioning system by regularly cleaning filters and ducts. This allows you to save a significant amount of energy and increases the life expectancy of your inverter air conditioner.

Hope the list helps you choose the best AC inverter according to your budget. If you have any questions about inverter AC selection, please post them in the comment section below and I will answer them.
