In-Depth Inverter AC Reviews for Indians

#1: LG KS-Q18YNZA (Best 1.5-ton Inverter AC in India)

When it comes to inverter air conditioners it hardly gets any better than the LG KS-Q18YNZA. So what makes it so good? Let’s find out.

LG 1.5 Ton 5 Star Inverter Split AC (Copper, KS-Q18YNZA, White, Low Refrigerant Detection)
  • Split AC with inverter compressor: Variable speed compressor which adjusts power depending on heat load. It is most energy efficient and has lowest-noise operation
  • Capacity: 1.5 Ton. Suitable for medium sized rooms (111 to 150 sq ft)
  • Energy Rating: 5 Star. Best in class efficiency. Annual Energy Consumption: 835.50 (KWh) units. ISEER Value: 4.73 (Please refer energy label on product page or contact brand for more details)

Energy Efficiency

While the heat rages on in summers so do your electricity bills because at 49 or 51-degrees turning the AC off is just not an option, right?

So what can you do?

Replacing your old unit with one of the most energy efficient ACs in the Indian market like the LG KS-Q18YNZA is the ideal alternative. But how do we know it works?

Well, the Bureau of Energy Efficiency (BEE) gives this AC a 5-star rating (so it is not just us saying it). This means it consumes just 800-900 units for every 1600-1800 hours it runs for

One of the reasons for that is the dual inverter technology which means it maintains temperature better than your average split AC as the motor isn’t constantly turning on.

And the other being use of copper coils over aluminum coils means the AC. But wait, there is more to these coils than just that.


Copper has a higher heat coefficient transfers heat faster than aluminum coils which make it more effective when it comes to cooling.

Apart from that, they are also the more durable choice and thus require little to no maintenance for years to come.

Oh and in case you did not know, aluminum coils are harder to repair whereas the copper coils are easy to repair and reuse thus saving you tons on overhead expenses when the time comes.

Furthermore, in order to prevent the coils from rusting LG employees the Gold Fin Technology.

And yes, this an upgrade over the standard Bluefin technology since it is faster and more efficient at defrosting.

Tonnage and Modes

The AC is a 1.5-ton AC which and thus ideal for rooms of about 180 sq. ft. which it can cool within minutes guaranteeing you a sound sleep even on the hottest days and nights.

This is mainly because it comes with modes like the Instant Cooling Cooling mode which promises to give you Himalaya like cooling within minutes.

Similarly, there is also the monsoon mode which ensures the room has perfect humidity levels for a comfortable sleep (monsoons just a whole lot easier to survive). 

Smart Diagnosis  

Having trouble with your AC? Well, most of the troubles can now be diagnosed via your mobile thanks to the Smart Diagnosis App.

It also allows you to book visitations via the app, in turn, saving you the hassle of having to make calls, send emails and so on.

Apart from that, with the refrigerant detector, LG eliminates any kind of guesswork by showing you precise levels of (so you know exactly when it needs a top up).

Other Features

With its 3M filter, the AC isn’t all about cool air but will also fresh air. By removing microscopic particles of about 0.3 microns it makes the room safer for people with allergies and asthma.

Also, it uses R32 refrigerant which is eco-friendlier than the R410 refrigerant that you find in most of the cheaper AC models (so you get to hop on the eco-friendly bandwagon without compromising on cooling).

You can also save goodbye to bulky stabilizer since and go wireless as the AC can handle mild fluctuations with ease.

Lastly, keeping out all the bacteria and mold does not require hours of labor-intensive work. You can do with a simple press of the Auto Clean button which dries up the heat exchanger within minutes.


 First and foremost, unlike most LG air conditioners this one does not feature a mosquito away technology which is a bit of a surprise.

And yes, the comes with a premium price tag which is not a surprise as it delivers top of the line features that will make going through summers a breeze.


  • It is the ideal AC for rooms of about 180 sq. ft.
  • It comes with a 5-star BEE Rating
  • Dual inverter technology means it is more efficient at maintaining the temperature
  • It also ensures silent operation
  • Copper coils are more durable and easy to maintain and repair when need be

#2: Blue Star IC512QATX (Best 1-ton Inverter AC in India)

Are you looking for an AC for a smaller room without compromising on energy efficiency? Then this is just what you need.

Blue Star is one of the most popular brands for both home and commercial air conditioning their IC512QATX does not disappoint either.

Blue Star 1 Ton 5 Star Inverter Split AC IC512QATX White)
  • Blue Star-Nobody Cools Better
  • Split AC; 1 ton capacity
  • Energy Rating: 5 Star

Energy Efficiency

You did not want to compromise on energy efficiency and neither do you have to. This AC also has a 5-star BEE rating.

This means it consumes a mere 400-500 units for every 1600 hours it runs for (so you can enjoy all day long cooling without any worries).

But don’t buy the AC only because it is energy efficient, it is also super smart and here’s why we think so.

Special Features

Unlike most air conditioners, this Blue Star model lets you set a precise temperature as it allows you an 0.5 increment (you want the temperature to be exactly 22.5-degrees, you get just that).

It is also equipped with the iFeel Technology. Here a sensor is placed in both the AC and the remote.

When you turn on the iFeel Mode, the sensors kick into action and the AC runs until area surrounding the remote comes down to the set temperature.

This is particularly helpful if you happen to sleep at a distance from the AC.

That is because most AC’s shut down once the area around it reaches the set temperature leaving other corners of the room slightly hotter.

Diagnosing problems with the AC is effortless as it comes with a self-diagnosing feature where you are automatically alerted of any issues within the AC.

And making it easy for you troubleshoot these problems via customer support or online searches are the special error codes provided (so you can get your AC up and running ASAP).


With copper condenser coils, Blue Star guarantees you long-lasting and low maintenance condensers as well.

And after years of service, you will find these cheaper to both replace or repair than their counterparts.

And the reason these coils survive for such a long time through all the moisture is that they are coated with the Gold Fin Technology which prevents rusting.

Tonnage and Modes

As you already know, this is a 1-ton AC and is the ideal model for a room of size of about 120 sq. ft. or smaller.

As for the modes, you want your room to be cooled in minutes, right? Well, turning on the Turbo Mode does exactly that.

Similarly, there are other modes like the Eco Mode, etc. that help you save electricity without compromising on cooling (even if that means cooling at 52-degrees).

Other Features

Just like the LG, even this AC prevents the growth of mold and bacteria with its Auto Clean features so you never have to waste time or money cleaning.

Oh, and you won’t ever lose the remote even in complete darkness as it comes with glow buttons. So adjusting temperature, mode, etc. does not disturb your sleep altogether.

Also, ensuring that is the Auto Restart feature which means in case of a power cut the AC resumes with the same settings.

Lastly, it also uses the eco-friendlier R32 refrigerant and does not require any stabilizer for operating until and unless fluctuations are common.


The AC only works efficiently is a smaller room. Placing it in a room above 130 sq. ft. means it may not cool every corner of the room well enough.
