Buying Guide for Inverter Air Conditioners

1. How Does An Inverter AC Work?

An air conditioner takes the indoor air and cools it. Then, the cooler air is passed through the evaporator and into the room. Air coolers used in the earlier days used to work in the reverse process. 

The way an inverter AC functions is akin to a car’s accelerator. We press the car accelerator gently or with force, depending on how much speed we want our car to move in. Likewise, the inverter depends upon the incoming air’s temperature to use more or less power.

2. Inverter Technology vs Non- Inverter Technology

An inverter is used to convert frequency. It is a commonly-used technology in home appliances. This technology’s job is to regulate electric voltage and frequency. In such air conditioners, the power supply frequency pattern of the compressors is adjusted, thereby varying the cooling capacity.

Inverter ACs control the gas flow rate, resulting in lesser power consumption. The inverter has an accurate temperature control mechanism, which takes care of any temperature fluctuation.

Power Consumption Comparison

In non-inverter ACs, however, the cooling capacity is fixed. The compressor is either started or stopped, thus controlling indoor temperature. This “stop-and-start” process is a continuous one; so, the power consumption decreases when it stops, but rises when it starts. Hence, the average power consumption is very much on the higher side.

Inverter Temperature Comparison

The RPM (revolutions per minute) of an inverter air conditioner is higher at the start; also, the compressor is on throughout the operation of the AC. More power is needed to turn an inverter AC on, as against a normal air conditioner. Once the temperature is set, the RPM of the inverter AC comes down, and lesser power is needed for maintaining the temperature. After a certain point of time, the temperature in the room crosses the set temperature, the RPM increases – thereby maintaining the temperature.

3. Advantages Of An Inverter Air Conditioner

  • Fast cooling –

The compressor speed in an Inverter AC varies, thereby ensuring perfect cooling in a much shorter span of time. Also, factors like what season it is, the number of people in the room, what time of the day it is, the prevailing climate of the location also vary the compressor speed.

The compressor speed in an Inverter AC varies, thereby ensuring perfect cooling in a much shorter span of time. Also, factors like what season it is, the number of people in the room, what time of the day it is, the prevailing climate of the location also vary the compressor speed.

  • Energy saver

In a non-inverter AC, the sound of the compressor switching on / off is distinctly discernible. However, in an inverter AC, the compressor is always on. What happens, therefore, is that – much power is used to start the compressor in a normal AC, but substantial energy (and consequently, money) is saved in an inverter AC. As per statistics shared by Bureau of Energy Efficiency (BEE), a 3-star non-inverter AC, e.g., is close to 7% less energy efficient than a similar rated inverter AC. Your inverter AC would run at 30-40% lesser cost than a non-inverter variant.

  • Voltage stability

Temperature fluctuations are non-existent in inverter AC, whereas it is quite frequent in non-inverter models. The speed at which inverter AC systems work varies, whereas it is always at the top level in a non-inverter AC.

  • Durability –

The thermostat setting of an inverter AC is accurate and consistent, allowing no room for fluctuations. This ensures much higher longevity, compared to normal non-inverter AC

4. Power Saving Mechanism Of Inverter AC

When we are using a non-inverter AC, we will notice that it will continue to make the room cool until the temperature drops below the thermostat setting. Once this happens, the compressor will get switched off and remain so till the room temperature rises again when it gets switched on – and that is how it continues. But this cycle results in much higher power consumption.

In an inverter AC, it will cool the room at a much faster rate, working at almost twice its capacity. At this point, however, the compressor motor slows down substantially, thereby ensuring that the room remains cool at all times. When the room temperature rises, more power is released – this maintains the consistency of the electricity consumption.

Example – a 1.5-ton inverter AC may operate at close to 150% of its capacity to ensure that the room cools down fast. Then, the speed may go down to only 10%, thereby maintaining the desired temperature. This varying speed also saves power.

5. Inverter AC Star Ratings

As per BEE, the most energy-efficient ACs are the 5-star rated ones. However, a 3-star rated inverter AC scores higher than a 5-star rated non-inverter type.

6. Drawbacks of Inverter Air Conditioners

  • In an uninsulated room, there will be higher power consumption – which will increase the electricity bill
  • In too much hot weather (e.g., 45 degrees Celsius and more), the efficiency will come down
  • The maintenance cost is quite high because of the high price of the components, as well as servicing charges
  • If the models are not commensurate to the size of the room, the room has a chance of becoming inordinately cold or hot; or the air may not dry enough, thus increasing the discomfort index and faster depreciation. 

7. Some Basic Parameters You Need To Remember When Choosing An AC

7.1 Room size – You might decide to go for the most expensive brand of air conditioner, but it would be of not much use unless the model bought is commensurate to the room size. If your room size is within 100 sq ft, a 1 ton AC will work just fine. For a room size of 100-200 sq ft, you would need a 1.5-ton variant. For bigger rooms, you would need more than one unit of the model.

7.2 The installation location of the unit – you need to determine where you would like to install the air conditioner. If your room is moderately sized with a small window, you might opt for a window AC. But in a room without a window, or where the windows are much lesser compared to the room size, a split unit would be better, considering the installation cost. 

7.3 Design of the air conditioner – Nowadays, we like to colour our rooms in different hues and shades.  And just like any other piece of furniture in the room, we would definitely want the air conditioner unit to fit in with that hue/shade as well. Most brands of ACs have a white-coloured variant, making it neutrally-coloured to be able to blend in with any colour. But many brands also have differently-coloured variants. If your room is coloured with a darker shade, you might decide to opt for a patterned variant, while going for a white-coloured unit for a room with a lighter colour. 

Also, if you are someone in line with modern technology, you might decide to go for a brand that provides home automation support – e.g., air conditioners which support WiFi connectivity, or “smart” air conditioners.                                              

7.4 Power consumption – In India, on an average, an AC remains operational for 8 to 10 hours per day. That inflates your electricity bills. Though inverter ACs consume less power, not all variants ensure similar consumption. E.g., a 5-star model will consume the least electricity, though these models are more expensive. However, it ensures savings in the long run – on your electricity bills.

7.5 Energy efficiency-based ratings – 3 stars, 5 stars, etc. are all ratings based on energy efficiency. 5-star air conditioners do consume the least electricity, but that is not to say that you need to go for only 5-star air conditioners. It might be the scenario that the AC at your house is used for only 5-6 hours per day (e.g., only at night). In this case, you would do well to go for a 3-star variant. If your daily usage exceeds 8 hours, then it would be advisable to opt for a 5 star rated unit.

7.6 Price – This is an area that depends entirely on your own comfort level. However, buying an AC is not something you do every week or every month. In India, a good inverter AC will cost you anything between Rs 30,000 to Rs 50,000. Choose the option of keeping in mind durability & long-term savings.

7.7 Your location – You would need a higher capacity air conditioner if you happen to stay in a city where outside temperatures are on the higher side. E.g., in Delhi & other parts of North India,   summer highs can reach 47-48 degrees Celsius, but the climate is dry, whereas in coastal areas like Mumbai, Chennai, etc., it may wander around the 40 degrees Celsius mark, but conditions are much more humid.

The AC will function differently in the above scenarios. In drier climates, we would want the room to cool down sooner, but in more humid conditions, it becomes more important to remove the humidity. So, if you are a resident of hotter & drier areas, it would be better to go for larger tonnage ACs while in the latter case, a smaller AC unit may do just fine.

7.8 The floor you stay in –  If you stay on a higher floor, you would need a high capacity air conditioner. And if you happen to stay on the topmost floor, then you may need to go for the highest capacity unit.

7.9 Quality of indoor air – A good quality air conditioner doesn’t only cool the room; it also ensures that you breathe fresh air by purifying the air in the room. That is where the role of the filter in the air conditioner comes into play.

We all know what damages impure air can do to us. Increasing cases of asthma, allergies, blocked nasal passages, etc. bear testimony to this fact. And a good quality inverter AC will ensure that in your room at least, you are free from such hindrances. 

With the room air clean, the efficiency of the air conditioner will also be increased, and the cooling performance will be much better. However, if the room air is unclean or dust-filled, you will run the risk of the evaporator coil of the AC getting choked – bringing down the cooling performance by several notches and defeating the very purpose for which the AC was bought.

7.10 The orientation of the room – If your room is west-facing or south-facing, then it would necessitate a higher capacity air conditioner. Neither servicing nor repairing / component replacement come cheap. So do a very careful study of the company’s authorized service centres in your city, terms, and conditions of servicing & repairs, availability of support during installation, and other related terms and conditions before zeroing in on your brand.

7.11 Room’s noise tolerance level – If you have decided to install the air conditioner in a quieter part of the house (e.g., the study or the kids’ bedroom), it would be good to remember that noise made by window ACs are much more than split variants. Split air conditioners have two parts – indoor and outdoor units. The outdoor unit has a fan and a compressor. So if it is possible to place the outdoor unit at a decent distance away from the room’s outer part, the noise level would be considerably reduced. 

7.12 Speed of cooling – This is a critical point for consideration. You need to be aware of the fan speed of the AC you have decided to go for, and the range thereof. The thermostat of the unit should be adjustable, and you should be having at least two fan speeds to make a choice. Room temperature would surely fluctuate, and the fan speed should be adjustable accordingly. 

7.13 Cost of installation – This cost will vary, depending on where you purchased the air conditioner from. Some dealers might choose to offer free installation, especially during festive and/or off-seasons. Otherwise, the cost of installation should be in the range of Rs 2000 – 3000 in most cases. 

Some bargaining in this case also helps, as is the case with most purchases in India! You would possibly need to pay extra for any additional copper wire required for installation. The installation staff will tell you everything about it. This cost should be in the range of Rs 200-250 per foot.

7.14 Cost of servicing – If your machine is within the warranty period the servicing costs would be lesser.  Compressor cost is a major component of the expenses you need to incur after buying an air conditioner. Beyond the warranty period (which is 5 years on an average for most brands), repairing your AC’s defective compressor can set you back by anything close to Rs 8000.

Cooling gas is another major cost factor. The copper tubes in the AC are meant for gas circulation. And these tubes can fall prey to rust & then crack, especially in more humid locations. This decreases the cooling factor, eventually making it zero. 

The tubes can be repaired by any local AC mechanic, who would be charging anything between Rs 500 – 800; and then, you would need to refill the compressor with gas, the cost of which should be around Rs 2500-2700 for a 1 ton AC. For most AC companies, their warranty would not cover this expense.

In more humid locations, it is quite possible that the coolant gas in your air conditioner would be emptied at least once each year, so you would need to earmark Rs 3000 – 3500 annually for this. In areas with lower humidity levels, this might be once every two years.

7.15 After-sales service – You would be spending a substantial amount of money on purchasing the AC.     So, it’s imperative that after-sales service should be an important determinant in your choice of brand.  

There’s no assurance that a high priced model would be flawless, and there would be no need for repair/replacement of components. Also, Bureau of Energy Efficiency (BEE) is frequently changing their ratings and standards, so rest assured that the resale value of your air conditioner would be very low,   as your model may become obsolete by the time you decide to replace it. 

Some brands will have a very good network of authorized service centres and after-sales touchpoints.   So before going for the purchase, it would be a good idea to check this network out on any search engine and also make a few calls to find out the response time. 

Certain other brands, however, will have a very small service centre network, centred mainly in major metro cities. So, if you don’t happen to stay in such locations, you would do good to avoid purchasing from such brands. 

7.16 Warranty facilities – Most brands offer a warranty of 5 years on the compressor; some go up to even 10 years. Without a shade of doubt, this gives a feeling of reassurance to us. 

But it is very important for us, as buyers, to understand the fine print and read between the lines of the “assured warranty” of the brands. E.g., for a defective compressor, the service staff may assert that the compressor damage now includes damaged piping. The pipe needs to be replaced. So they would not be able to repair the compressor under warranty terms. 

So, you should ideally talk to a staff of the AC company (not a supermarket or multi-brand showroom salesperson), who can explain to you what are the exact deliverables of the company under the warranty conditions. And also, read up some user reviews on a lot of sites on the net, to get some frank, first-hand, unbiased reactions and user reviews.    

Also, some companies may not honor their warranty commitments if the installation has been done by local mechanics and company authorized personnel. Often, we might take recourse to these local people as they are more easily available and also much cheaper. But we might stand to deprive ourselves of benefits under the warranty if we do that. So this is something you need to be clear about before installation.

7.17 Add-on “traps” – The dealer is enticing prospective buyers with schemes like “free microwave” or   “free external Hard Disk Drive” with the air conditioner. Many of us rush to buy the air conditioner from that particular retailer.

Well, for all you know, you might be falling for a trap.

It is highly probable that the dealer is on a stock clearance mode, and you will end up buying a defective model. So, keep your eyes and ears open and do a lot of research before going in for such offers.

8. Which Model To Go For?

There are a lot of options available for you in the Indian AC market. Each variant flaunts its “unique” feature, compounding your difficulty to make a choice.

However, we will offer you some suggestions which will make things easier for you.

You need to make a checklist. There will be some “must-have” features in every model and then, there will be additional ones. You need to understand your essential needs from an AC and match your requirements with the features being offered. If the features are more than your basic/essential needs, then go ahead & buy that model.

3. What is ISEER Rating for air conditioners?

In simple words, ISEER ratings refer to cooling seasonal total load divided by cooling seasonal energy consumption. The ratio that is derived out of this calculation is used to designate the correct star to the air conditioner.

4. What is wrong with buying a non-inverter AC?

The main disadvantage of a non-inverted AC is that it is more costly to repair and maintain than inverted ACs. Besides, if your room is not insulated, the non-inverter AC might not work properly and can cause an increase in the electricity bill.

5. What are the common modes in an inverter AC?

Some of the common modes in an inverted Ac are Cool Mode, this is the default mode in most air conditioners. Then there is Fan Mode; in this mode, the compressor does not work but only the fan runs. Energy-saving mode is also common in inverted air conditioners.

6. Do I need to buy a voltage stabilizer with an inverter AC?

No, you don’t need to buy a voltage stabilizer with an inverter AC. The voltage range of inverted air conditioners is usually around 160 to 245 V. If your inverted AC comes under this range, then you don’t need a voltage stabilizer.

7. Does Inverter AC really save electricity?

Yes, inverter AC saves energy. A good inverted AC can save as much as 40 percent energy on your annual electricity bill. Inverted air conditioners maintain the temperature of the room. Besides, with no compressor operations, the inverted air conditioners run on less energy than usual.

8. What are some advantages of inverter air conditioners?

Some main advantages of inverted ACs are that they are very eco-friendly and energy efficient. One can save a lot on their electricity bills with these air conditioners. They give faster cooling and heating and have a longer life than other common air conditioners.


From what we found, the Voltas 1.5 Ton 5 Star Inverter Split AC provides unparalleled cooling. Due to inverter motor it consumed very low amounts of power and the cooling was even. There were no pockets of warm air in the room and as an Indian manufacturer, Voltas has done its best at providing quality.

Due to the pure copper coils to the durable compressor, it is worthy of being the first among equals with an annual consumption of only 830 units.

Our second choice was LG 1.5 Ton 5 Star Inverter Split AC (KS-Q18YNZA) which is reasonably affordable and provides all the added features that are useful. Both these units have R32 refrigerant that is environment-friendly. The LG air conditioner uses the patented dual rotary air compressor with its quick Himalaya Cool technology. Both are highly effective and well-made machines.
