Inverter AC is the best way to beat the heat during summers in India. Because they consume 30 to 40% less power compared to regular ACs.
We have spent a lot of time on research and provided guidelines on How to choose an inverter AC in this article. We highly recommend considering below 3 main factors to take an informed decision.
For proper cooling, choosing the right capacity is important. Smaller size models cannot provide sufficient cooling for large rooms. If a large capacity AC is used for smaller rooms, then you waste money on power bills. Below are the general guidelines…
- For very small areas (0 to 80 Sq.ft.) –0.75 ton inverter AC is suitable.
- For small rooms (80 to 150 Sq.ft.) – 1 ton Inverter air conditioner is preferred choice.
- For medium room (150 to 200 Sq.ft.) – 1.5 ton Inverter air conditioner is required.
- For large rooms (200 to 300 Sq.ft.) – 2 ton Inverter AC is necessary.
Note: If you want movable option, then go for Portable air conditioners
2. Copper or Aluminum Coil
Coils are responsible for transferring heat. Air conditioners have either copper or aluminum coil. Compared to aluminum, copper coils have more heat transfer efficiency, durability and easy to maintain.
Refrigerants are responsible for cooling the air. Most of the refrigerants like R-410A, R-32, R-134, R22, and R12 cause ozone depletion and global warming. We recommend to prefer inverter AC models with environmental-friendly and greenest refrigerants like R-290 (propane) or R-600A (Iso-Butane).

Buying Guide – All You Need To Know About Inverter ACs
What is Inverter AC?
In the recent years, air conditions have come with inverter technology. With the help of this new technology, AC’s will regulate the compressor speed and control the temperature constantly. Because of the inverter presence, these machines can function without making any noise, consume less power and provide better cooling environment. The main benefit of using inverter AC when compared to conventional AC’s, they consume 50% less electricity.
Difference between Inverter and Non Inverter AC
Coming to choose the best air conditioner either for home or office, inverter ac or Non inverter AC are the good choice. Annually millions of AC units get sold and on an average 10% of the utility bill for households is only on cooling units.
Inverter AC Non Inverter AC Inverter AC has the compressor motor and variable speed. Compressor is “ON” all time. Non inverter has fixed compressor and speed is fixed. Compressor goes “ON” and “OFF”. To control the flow of refrigerant inverter AC adjust the speed of the compressor. Based on the temperature of a room non inverter AC delivers the fixed amount of power. In the inverter AC the cooling and heating is an automated process The non inverter ac goes “ON” and “OFF” so that it can keep the temperature within the assured threshold limit around the room temperature by making it less eco friendly. Inverter AC are a little more expensive than Non inverter AC Non inverter AC costs less than Inverter AC. However, installation of a non inverter AC unit will probably cost more than what an inverter AC will cost.
Different Types of Air Conditioners
Based on their working features, AC’s are divided into different categories. We have mentioned them below for your information. Read them carefully to make the right choice.
1.Window Air Conditioner
This was one of the common AC’s we seen in Indian homes. These air conditioners have the ability to cool single room at a time. If you have a large home, then you may have to install them in every room you want to cool. Though not inexpensive, they are still popular choice for people who live in apartments and small houses.
These air conditioners have components that are much similar to a central air conditional. Some of these components are evaporate coils, fan, compressor and a refrigerator. However, they are placed together in a small unit which can be mounted into a window.
Window ACs are available in different sizes suitable for small or large rooms. Size of the air conditioner directly impacts the cool air generation. However, a window AC’s cooling capability is limited because of its small size and static location.
- Suitable for cooling individual areas or single rooms.
- Less expensive than installing a central air conditioning system.
- Easy to uninstall and relocate to a new residence.
- Additional ductwork is not required.
- Compared to other air conditioning systems, they are pretty noisy.
- As installed to window, it can obscure outside view.
- It has to be installed close to a suitable electric outlet.
2. Split Air Conditioner
This AC type has become very popular in the recent years. Split conditioners have one indoor unit and one outdoor unit. The outdoor unit will be installed to the adjacent exterior wall. This unit contains a condenser coil, compressor, and capillary tubing (or expansion oil). The indoor unit has a cooling coil, air filter and long blower. The outdoor and indoor units are connected through conduits that carry refrigerant lines, drainage tubes and carry power.
- As the main noise making components (compressor and fan that cools down the compressor) are placed in the outdoor unit, split air conditioner is quiet.
- Installation of window AC is limited, but split AC can be installed anywhere. It doesn’t require large holes in the walls or expensive ducts for installation. And moreover outdoor compressor unit can be installed long away from the unit. They are easily to clean and maintain as well.
- Split air conditioner unit (both indoor and outdoor) has to be installed only by a professional.
- Expensive than window air conditioners.
- Though it can whisper silent inside, but exterior unit can be very noisy. You may have to think about a place to install the outdoor unit without causing any trouble to neighbors.
Things to Consider While Purchasing an Inverter AC
Purchasing an air conditioner is not a small investment, you have to make sure the product you choose suits your requirements perfectly. Below, we have mentioned important factors that help you make the right decision.
While purchasing an inverter AC, first thing you have to look out for is its cooling capacity. It is usually measured in tons. The measurement “ton” refers to the amount of heat removed by AC per hour.
Basic thumb rule you have to consider while checking the cooling capacity is – higher the ton is, greater will be the cooling capacity – which means that AC can cool a large space quickly.
To know suitable capacity for your requirements, first thing you have to do is – measure the room you will be installing the AC. Based on this information, you can choose an air conditioner with suitable cooling capacity. You can check the capacity range of air conditioner in its instruction manual or product specifications.
We have provided a table below which represents room size and its suitable capacity. Sometimes, the below tonnage representation can vary based on certain factors like usage, number of people in the room and number of appliances.
|Size of the Room (In Sq.ft)||Capacity (In Tons)|
|0 – 80||0.75|
|80 – 150||1|
|150 – 200||1.5|
|200 – 300||2|
2. Power Consumption and Star Ratings
Almost all the inverter air conditioners in India come with star ratings – which represent power consumption and energy efficiency of the product. EER represents Energy Efficiency Rating and ISEER represents Indian Seasonal Energy Efficiency Ratio. These parameters directly impact the star ratings of inverter air conditioner.
So, whenever you are checking for these ratings – remember that higher the stars are, the more energy efficient the air conditioner will be. And the same implies to ISEER as well. This means that – AC with more star ratings will consume less power while operating.
If you want to reduce monthly electricity bill, then choose an inverter AC with more star ratings.
Compressor is the most important component of an air conditioner. So, you have to take more care while analyzing this factor. Before learning different types of compressor and which one to choose, first we shall understand the role of a compressor in AC.
Compressor’s working principle is – compressing refrigerant gas of air conditioner into high-pressure liquid at high temperatures. Next, the high-pressure liquid will pass through condenser coil. In this stage, it will lose the heat and come out of the air conditioner as cool air.
Now, we will look into two different types of compressors – reciprocating and rotary. Read the below description carefully to understand which one suits you the best.
- Reciprocating Compressor
This compressor type is actually same as one in an automobile engine. It contains a cylinder and piston. Piston components moves to back and forth continuously to generate compression and expel gas. This compressor is very easy to maintain and works efficiently even in high temperatures. But it generates noise and moreover the expelled air will have high temperature.
- Rotary Compressor
Most of the recent air conditioners have rotary compressor. As the name implies, this compressor uses rotors – which are carefully arranged with less clearance in between them. These rotors move in opposite direction to expel air at high pressure. As this process results in no noise, it is suitable for industries and large offices. And moreover the air coming out of the compressor will be at low temperature. But when compared to reciprocating compressors, rotary compressors are costly and require high maintenance and usage to achieve optimal result.
Condensers present in an air conditioner use coil for cooling the air. Apart from that, coils are also responsible for improving the efficiency and controlling the power consumption.
Coils are made up of either cooper or aluminum. These two types are very popular as they can improve efficiency and control the power consumption. Let’s check out the detail description of these two types to understand which one best for your requirements.
- Copper Coils
Compared to other coils, copper coil is easy to maintain and lasts very long. This is the most preferred choice, as they cool the air within less amount of time. However, they are a bit expensive compared to other types. Because their anti-corrosive properties, copper coils are best suited for coastal and high humidity areas.
- Aluminum Coils
Compared to copper coils, they are less expensive and require more maintenance. But aluminum coils take more time to cool the air and don’t last long. But being more malleable than copper, aluminum can be molded into any desired shape easily.
A refrigerant is usually present in air conditioners and refrigerators. It is a main component of any appliance with freezing technology. Refrigerant can be used in the form of gas, liquid or fluid. In an air conditioner, it is usually present inside condenser coils.
Its working principle is to absorb heat present in the room and expel it into the outside environment. If the refrigerator works efficiently, then heat will be expelled quickly and the room gets cool faster.
When switch on the air conditioner, first the refrigerant or coolant (present in gas format) will pass through compressor. Under high pressure, the gas refrigerant gets converted into liquid and passes through coils. Now the liquid refrigerant is converted back into gas due to low temperature. Finally, the AC will release the cool air by taking away the heat.
There are several different types of refrigerants. We have mentioned them below for your information…
- Chlorofluorocarbons (CFC)
It is sometimes referred as R12 refrigerant. It is one of the first coolant to use in an AC. They perform efficiently but reduce the ozone content in the atmosphere. However, only few air conditioners use this refrigerant.
- Hydro- Chlorofluorocarbons (HCFC)
It is commonly known as R22. Due to environmental issues, R12 is replaced with R22. It is commonly used refrigerant in the modern air conditioners. Though it is not completely environmental friendly, it may be replaced with another coolant in near future.
This refrigerant is much similar to R22. And moreover it is environmental friendly and doesn’t affect ozone layer. This is the reason most of the manufacturers in india are considering to use this coolant. Apart from that, it delivers maximum efficiency without causing any harmful effects to the environment.
- Hydrocarbons (HC)
This coolant, which is the future of coolants, is to be used in air conditioners. This is the most environmental friendly coolant available. That is why most of the companies are trying to use this coolant for their air conditioners. At present, this coolant is used in most of inverted air conditioners that has made certain of the shining future this coolant brings in the upcoming air conditioners.
6. Cooling Speed
Choose an air conditioner with multiple cooling speed settings. Never opt for an inverter air conditioner that comes with single cooling speed – as you won’t able to adjust the temperature according the temperature outside.
7. Air Quality
When using air conditioner, indoor air quality is one of the important things to consider. That is why purchase an inverter AC with good filter to maintain the air quality inside the room. Having a good filter not only provides clean air but also improves cooling performance and energy efficiency of the air conditioner – which can be disrupted due to dust clog in evaporator coil.
Almost all air conditioners have certain ability of controlling humidity, along with cooling the inside air. However, some of them are better than the others. Some inverter air conditioners come with separate dehumidification settings – which is helpful in areas with high humidity levels.
9. Remote Control
Remote controls help you adjust temperature settings anywhere within the room. It comes very handy to increase or decrease temperature in the middle of the night.
As the name implies, this feature lets you set the AC at particular temperature and desired time. Once the duration completes, the AC will automatically turn on and off without your intervention.
11. Noise Level
Window air conditioners make a lot of noise, which can be uncomfortable while sleeping. Split ACs make less noise when compared to others. But some air conditioner models work whisper silent. So, while purchasing check the noise levels of the product. Make sure the noise levels are bearable and don’t interrupt your sleep or work.
12. Easy Controls
When compared to some models, certain inverter air conditioner models have easy operation controls. So, while analyzing the options, check whether it can easy to use or not.
13. Fan-Only Operation
During cool morning and nights, your AC may not require compressor to generate cool air. In that situations, fan-only feature can be helpful as it just circulates cool air already present inside the room. This will reduce the energy consumption and power bills as well.
14. Digital Display
Digital display enables you to see the temperature and other operation units when the air conditioner is working. It is especially helpful during nights and dim lighting conditions.
Every air conditioner comes with certain basic features like temperature control (16 – 29 degrees) and auto mode. But with innovation modern technologies, inverter air conditioners have come up with some amazing features.
For example, turbo mode (instantly cools down the room), sleep mode (maintains 22 – 24 degrees’ temperature constantly throughout night), dehumidifier (maintains proper humidity levels in the air), filter (removes dust and other pollutants circulating in the air).
Some modern inverter ACs also come with advanced features like automatic sensors, Bluetooth accessibility, WiFi enabling and others. Having these extra set of advanced features lets you customize the experience according to your requirements.
When it comes to features, having more features improves the convenience of using the inverter AC. Also, remember that as the list of features increases, the price of the product also increases.
This depends on how much you want to spend. Air conditioners are one-time investment which will last for at least 10 years. So, it is better to invest only in the best inverter AC. The cost of inverter air conditioners in India ranges from Rs. 30,000 to Rs. 50,000. If you have budget constraint, then go for a basic model. If price is not a major factor, then it is best to purchase model with maximum features.
When it comes to home or electronic appliances, warranty is one of the important aspects to check. It is better to choose a product that comes with long warranty period. During those years, you can get any repairs fixed without no extra cost.
18. After-Sales Service
Few brands have very bad after-sale. So, it is better to check out before making the purchase. For more information, check out the reviews of customers.
19. User Review
As air conditioner is not a small investment, it is better to have an idea of someone else experience of that particular product. So, check out the reviews and ratings of people who are using it. These reviews will let you know whether the product is worth purchasing or not. Though some reviews may not be genuine, it will at least provide a better insight of the product.
Advantages of Inverter Air Conditioner
Inverter air conditioners have several benefits. We have mentioned some of the main factors below…
- Saves Energy
This is by far the biggest benefit of using an inverter AC. Compared to other air conditioner types, inverter air conditioner saves more energy. According to certain sources, using an inverter air conditioner can reduce electricity bills by 30% to 50%.
- Quick Cooling
Compared to regular air conditioner models, inverter AC can provide quick and constant cooling. Due to the presence of various compressor speeds, it can provide cool air quickly even if the outside temperature is very hot.
- Comfortable Experience
The start-up time of inverter AC, when compared to a regular air conditioner, is 30% less. Also with this type of air conditioners, there will be no temperature fluctuations and voltage peaks from the compressor. This means that the appliance will work whisper silent.
Power Consumption – Inverter AC Vs Non-Inverter AC
Air conditioners available in Indian market have different capacities and efficiency ratings. In general, AC’s with 5 star ratings is considered to be the most energy-efficient appliance.
Below, we have provided a table representing power consumption of AC with different capacities and their respective star ratings.
|0.75 ton||1 ton||1.5 ton||2 ton|
|3 Star Non Inverter||627||828||1235||1548|
|3 Star Inverter AC||550||726||1077||1344|
|4 Star Inverter AC||499||658||972||1208|
|5 Star Non Inverter AC||576||760||1130||1412|
|5 Star Inverter AC||421||557||815||1005|
Below, we have explained how much difference of power consumption or energy efficiency between lower and higher rating air conditioners.
A 1.5-ton capacity non-inverter 5-star AC consumes 1130 units of power in 1600 hours, as per BEE statistics.
In general, a 3-star inverter air conditioner consumes 1077 units in 1600 hours. When it comes to higher efficiency like 4 and 5-star inverter AC, the consumption reduces to 972 units and 815 units respectively. This proves inverter air conditioners can save more power.
Few Tips For Maintaining Air Conditioner Properly
- Usually we don’t use air conditioners during monsoon and cold seasons. During this time, the filters present in AC will get accumulated with dirt. This can impact the air flow of the appliance and make it work harder, leading more power consumption. So, before reusing the air conditioner during summer time, we recommend to get the filters cleaned properly.
- For increasing the efficiency of the inverter air conditioner, we recommend to clean the condenser unit regularly. It is also recommended to replace the refrigerant with new one at periodical intervals.
- Electronic devices like laptops, television, music appliances, and computers emit a lot of heat when they are in working mode. If you have any of them in your room, then make sure to turn them off when not in use.
- Also, you should never place any electronic devices near thermostat of the air conditioner. Because it will directly affect the thermostat functioning. This will in turn make the condenser work even harder.
- While using an air conditioner, insulation of the room should be at optimum. Doors and windows are the main areas where air can easily escape. So, you have to make sure there are no gaps for the air to escape. It is good to have carpets and rugs in the room as they prevent air from escaping from below the doors.
- If you want to save electricity, then it is better to maintain temperature at 24 to 25 degrees Celsius.
- It is good to have a professional AC check-up once in a while. They will clean the evaporator coils and condenser coils. Sometimes dust gets accumulated in the coil fin gaps which can add more load on the condenser unit.
- When the air conditioner is not in use (during winter months), we recommend to cover the compressor. This lets the AC to remain perfectly fit to work in the next coming summer.
- Rear drain is an important part of the air conditioner as it expels water out. If the water accumulated inside, it will damage the coils and even lead to electrical short circuits.

Amazing smell of perfume can create a good environment in the room. However, you have to cautious while using it as some people can be allergic to them. If you want to remove foul or bad smell, then we recommend opening up the windows and doors for some time before switching on the AC. The fresh air will remove the foul smell present in the room. So, you don’t have to use perfumes for dealing with the odors.
However, if you still want some good fragrance in the room, then go for room fresheners. This doesn’t affect the AC performance and makes sure the room smells good. We also recommend to clean the air conditioner regularly.
Most of us know that air conditioner reduces the temperature of the room as per our requirements. But we don’t know exactly it works. Actually, when you turn on the air conditioner, it takes air present in the room and passes it through evaporator and expels it out into the room again.
During this whole process, three main important components play the major role. These 3 components are…
Compressor – This component ensures there is proper refrigerant circulation between evaporator coils and condenser. This process is performed in a closed loop.
Condenser Coils – They are a collection of several tubes that are filled with refrigerant (mostly Freon). These coils are responsible for eliminating any heat generated from gas refrigerant. And it expels the heat through outside door. It will also cool down the hot refrigerant into liquid again.
Evaporator Coils – The work of evaporator coils is exact opposite of condenser coils. These coils have the refrigerant which is responsible for removing heat and moisture present in the room. This process will convert the refrigerant into gaseous form.
Now that you have understood the roles of the components individually, now we will dive into the working process of the air conditioner.
*When you turn on the inverter AC, first compressor will convert the gas into high-pressure hot liquid.
*Next, the hot liquid will flow along the condenser coils for the condensation process. During this process, heat will gradually escape through outdoor unit and liquid will cool down. Though, it cools down, the temperature of the liquid still stays high.
*Now, high pressure liquid will be reduced to low temperature liquid through expansion valve.
*Finally, low pressure liquid passes through evaporator coils. During this process, heat from the room with absorbed which transforms the liquid into gas As heat is absorbed, you will experience cool air inside the room.
A dual inverter AC is a new addition in the market, and it is an improvement over the general inverter AC. It comes with dual rotary motors and hence, it is so named.
The product has a wider rotational frequency due to which it is more efficient in its performance. The cooling will be faster, and there will be lesser noise. Not just that, there is going to be a better saving in the power bills, and therefore, it is a more profitable product to buy.
A general inverter AC works the best when the outside temperature is below 46 degree Celsius. But for a dual inverter AC, this temperature limit extends up to 52 degree Celsius. Other than that, it works in the same fashion as a general inverter AC by regulating the speed of the compressor. If your area sees the extreme of temperature in the summer and you are a heavy user of AC, go for a dual inverter AC. You can have a look at our best air conditioners in India list above.
The inverter technology is primarily available for split ACs. However, brands like LG and Voltas have launched a handful of models where the Window ACs are having inverter technology in the compressor.
The Bureau of Energy Efficiency (BEE) is responsible for giving star ratings to the ACs to help the customers identify the energy efficiency of the different models of ACs. In 2018, BEE introduced a new star rating label named Indian Seasonal Energy Efficiency Ratio or ISEER. It is an improvement over the previous rating system as it takes into consideration various climatic zones of India, variations in the temperature ranges and much more.
Just because a non-inverter AC costs less than an inverter AC does not mean you buy it. The initial cost will be cheaper by a few thousand, but in the long run, you have to spend thousands and thousands in the power bill. The non-inverter ACs have a fixed speed compressor, and therefore, there are less energy efficient. In other words, they consume more energy or electricity, and therefore, the power bill will be higher in comparison to inverter ACs.
Secondly, the non-inverter ACs always overcool the room which means if you set the temperature at 25 degree Celsius, the ultimate output will be around 22 to 23 which can be uncomfortable for many. This is because the fixed speed compressor is designed for the peak heat load. Even though the thermostat switches off the compressor at 25 degree Celsius, the refrigerant manages to absorb heat from the room air and convert into gas.
Lastly, non-inverter ACs are fast becoming obsolete. Therefore, you should buy them at your own risk because the spare parts may not be available in the future. The ACs needs annual maintenance, and at times, there are certain parts you have to change in case they get damaged somehow. In such a case, if the spare part is not available, you have to buy a new AC. This is why it is always best to buy the latest model, and most of the latest AC models have inverter technology.
Voltage fluctuations can harm electrical equipment in inverter air conditioners. Sometimes, they can cause permanent damage as well. So, it is important to connect AC to a voltage stabilizer. They protect the air conditioner by stabilizing the utility voltage.
When there is a voltage fluctuation, the stabilizer regulates it and deliver consistent output voltage. For example, if the voltage is high, then it will reduce the intensity and send it out to the equipment. And vice-versa.

There are main four modes available in an inverter AC namely auto, cool, dry, and fan.
Auto Mode – In this mode, the cooling required for any room is determined automatically by the air conditioner based on the outside temperature. It is perfect when you are sleeping at night or planning to run the AC for a long time whereby the outdoor temperature variation is likely.
Cool Mode – The cool mode is the manual mode of cooling where you set a particular temperature, and the cooling effect will be served by the machine accordingly. It is best when you do not want that chilly atmosphere in the room or want instant cooling by fixing the temperature at the lowest point.
Dry Mode – This mode is applicable in the rainy season or when the room is humid. This is when the AC works more like a dehumidifier. You will find it better to breath as this can eliminate the moisture from the room air. Besides, too much moisture in the room air can damage your wooden furniture and promote the presence of bacteria in the air.
Fan Mode – Going by its name, it is the mode where you use your AC as a fan to circulate air in the room. You can use it in the winter season to heat up the units of ACs so that it does not get jammed and need maintenance service. It is also useful when the temperature is pleasant in the room, but the air is suffocating due to lack of circulation.
The air filter of an AC is where the dust and airborne particles accumulate. The more the accumulation, the lesser will be the quality of air in the room. Therefore, you should clean the air filters from time to time to maintain a proper level of air quality. If you can, you should do it once or twice a month if you are using the AC regularly. You should ask the service provider how to open and attach the air filter when they come to install the AC. Apart from that, you should opt for annual maintenance service where they clean the air filter thoroughly along with other parts.
There are a lot of things you can do in order to maximize the performance of your AC. First of all, you should ensure that the outdoor unit is facing an open area so that there is no blockage in the air flow.
Secondly, you need to see that there is no blockage in the drainage pipe and therefore, you should place it a foot above the ground so that insects cannot get in or kids start pulling them.
Thirdly, the indoor unit should not be placed on the wall which gets direct sunlight as it can get heated up.
Fourth, you should use blinds, curtains or sun films on the windows to reduce the heat input. This will ensure that the AC will take less time to cool the room and thereby, saving the power quite significantly.
Fifth, you can install a false ceiling as the heat for the ceiling will not radiate that much directly in the room. Sixth, you should open the windows and let out the hot air from the room using the ceiling fan you have or the fan mode in the AC before closing the windows and starting the cool or auto mode.
Last and the most important step to increase the performance of the AC is to clean the filter regularly. Unclean filter obstructs optimal cooling, and the efficiency goes down by 10%.
So, if you have decided to buy an AC to beat the heat, you should always opt for an inverter AC rather than non-inverter ones. Since it requires quite a chunk of money, it is your responsibility to research well before buying. The above buying guide can help you through the process.
