Window A.C are ideal for small rooms with a window space, these AC are mounted in the wall of the room.

Window AC is a single unit AC, with one face of it gets popping out outside the window. The other side of it is installed into the wall by the technician.

But there are certain drawbacks of the window AC. Window Ac occupies more space than the split AC.

Multiple cooling units are not an option for the window AC.

Also it has been observed that window AC makes more noise than the split AC.

In spite, of all these drawbacks, people still buy window AC, especially in northern parts of India because of its affordable price range.

If you want to go through our review on the Top Best Window AC in India, then you will get much more detailed information about them.

Copper Coil vs Aluminum Coil

While buying an A.C the first thing which comes to your mind is power consumption, 5-star ratings, eco-friendly, etc.

But the most important thing you need to decide is whether to buy one which has Copper coil or Aluminum coil.

Type of coil in the AC plays an important role in the performance and the longevity of the air conditioner.

Primarily there are two kinds of coil in the AC; condenser coils and the evaporator coils. The material of these coils are either copper or aluminum.

The coolant or refrigerant gas needs a medium by which it should travel, and that is when copper or aluminum coils comes into picture.

Copper coils are always preferred by the industry experts because of its cooling capacity.

But in comparison with copper coils, the aluminum coils were much cost effective.

Copper vs Aluminum Coil AC [Pros & Cons]

Because of which, since it was introduced for the first time by GE in 1970, it brought down the subsequent cost effectiveness of the manufacturers.

AC became more affordable to the common man thereafter.

Well both Copper and Aluminum comes with their pros and cons. The heat transfer rate is better for the copper coil.

Copper is also more durable than aluminum and easy to repair on field.

On the other hand since aluminum coils are cheaper than copper, it is more affordable.

Also as compared to the copper lesser metal is required to make the coil. Hence the overall cost is low.

Buying Guide for Air Conditioners (Best Split AC In India)

Buying-Guide-for Air-Conditioners

Air conditioners have become a necessity nowadays because of the increase in global warming and ozone layer depletion.

The present scenario is quite jittery and dubious, as you can see there are a lot of air conditioner brands available in the market all claiming to provide something which its competitor is not providing.

As a consequence of which, AC buyers have become more confused while purchasing the best split AC in India.

The Basic Difference between the Inverter and the Non-Inverter AC and its graphical representation.

Difference between Inverter and Non-Inverter AC


We highly recommend you to understand the basic difference between the Inverter AC and non-inverter regular AC.

Inverter AC runs continuously to maintain a uniform temperature throughout the time it operates and in the process consumes a less or minimal amount of power.

Whereas regular AC compressor is designed in such a way that it turns on and off to maintain the desired temperature in the room.

But, the flip side to it is that, whenever it restarts, it consumes three times more power which results in more electricity bills.

Advantage of Inverter AC because of their variable power control

Inverter AC has the upper hand

How Air Conditioner works

Refrigeration Cycle inside the Air Conditioner

Air conditioning is the conditioning of the hot and humid air within a certain space usually a building or a house that is measured in square feet.

Air conditioning of the air, if we look at it, from physics or dynamics of the airflow point of view; involves heating, cooling, humidifying, or dehumidifying of the hot air.

The purpose of air conditioning is to provide maximum indoor comfort.

Ideally, there are two processes primarily involved in the air conditioning mechanism.

Heating process

This process occurs in reheated and pre-heater of the air conditioning system, in fact, the heat should ventilate the air.

This process can be done using the principle of electrical energy. In reality, the air is heated via heating water.

Cooling process

The main component that serves to cool down the air is the evaporator.

This cooling is done by the cold water which allowed for indirect cooling.

Air conditioners basically function or revolve around three basic processes of physics.

These three processes are evaporation, condensation, and compression.

A. Evaporation

An evaporator is basically a heat exchanger coil that’s responsible for collecting heat from inside a room through a refrigerant gas.

This component is known as the evaporator and is where the liquid refrigerant absorbs heat and evaporates to become gas.

B. Condenser

The condenser receives the vaporized refrigerant from the compressor, converts it back to a liquid.

And expels the heat outside. It is also located on the outside unit of the split AC.

C. Compressor

A compressor is where the compression of the gaseous refrigerant occurs.

It’s located in the outside unit, for example, the part that’s installed outside the house.

Things to consider before buying an Ac

If you are planning to buy the Best Split AC in India, then you must consider these point for your ultimate buy.

Cooling capacity is determined by the size of the Room against the capacity of your AC in tons.

Most of us are familiar, that while buying an AC, we look for either a 1 ton or a 1.5 ton A.C.

The general principle works here is that, with a higher ton of air conditioner, more the amount of heat the AC removes from the room within one hour.

Cooling Capacity

Table to calculate the square feet to tonnage of the AC.

The number of people residing in the room also is a key deciding factor which most people tend to overlook and only go by the square feet capacity of the room.

If a family contains many people residing in a single room, which is a very common aspect in India.

Especially in the northern part of the country, the heat emission will be higher from the bodies.

Therefore, you may need an AC unit of higher tonnage to cool the rooms as compared to the same capacity of the room if used by a lesser number of people.

  • 0 to 80 Square feet sized rooms we recommend 0.75-ton Inverter air conditioners.
  • 80 to 120 Square feet sized rooms we recommend 1-ton Inverter air conditioners.
  • 120 to 190 Square feet sized rooms we recommend 1.5-ton Inverter air conditioners.
  • 190 to 300 Square feet sized rooms we recommend 2-ton Inverter air conditioners.

The location of your room also plays a significant part in deciding the cooling capacity the AC would have to bear, and how much ton of ac to go for.

If your room is top storied and it is touching the roof, then the rooms can appear hotter if the ceiling of your room gets direct sunlight during the daytime.

Usually, these happen the most in multi-storied buildings and flats where the ground floors usually had been observed with 1 ton AC and the top floor are featured with 1.5 ton or a 2 ton AC.

Calculation for the tonnage of Best Split AC In India

Ton is considered as the cooling capacity of an AC. Tonnage is the amount of heat that the AC removes from the room per hour.

To find the ton AC required you should know the length, breadth, and the height of the room.

Once you have the figure (in feet) just multiply all of the three to get a total.

Formula for the Total = Length (feet) x Breadth (feet) x Height (feet)

Most air conditioners are rated in BTU per hour (British thermal unit). You can convert it to tonnage and the mathematical calculation goes like 1 ton is equal to 12,000 BTU per hour.

The measurement is done as 3,412 BTU = 1Kw/hr.

The general calculation follows as; 1 ton is equal to 12000 BTU/hour and a 2-ton AC unit would be rated at 24,000 BTU/hr.

The higher tonnage AC will provide more cooling effect.

Finally, we need to check the power consumed by the unit in watts and the star rating which is based on the EER (energy efficiency ratio).

If we convert the cooling capacity to watts (1 ton = 12000 BTU = 3517 watts) and then divide it by the power consumed to achieve this we get the EER, the higher the better (this shouldn’t ever be below 2.3 and should be around 3.5 for a 5-star rating).

Ozone Layer Depletion linked with the AC Refrigerants comparison

There could be several reasons for the depletion of the ozone layer.

Environmental pollution from the industries increasing the toxic in the atmosphere is a major influential factor to this climatic change.

The ozone layer is very important for maintaining the atmospheric balance. The ozone layer effectively blocks almost all solar radiation of wavelengths less than 290 nanometers from reaching Earth’s surface.

The amount of ozone layer is directly proportionate to the global warming and the glacial melting of the earth.

Hence, removing the ozone layer depletion should be our prime responsibility towards the mankind and the mother earth.

As a part of our own responsibility, we should start using air conditioners with eco friendly refrigerants like R290 and R600A respectively.

As the demand for air conditioners is on a gradual rise, Manufacturers will quickly switch over to eco-friendly refrigerants from CFC, HFC, and HCFC and so on and so forth.

Energy Efficiency (EER, SEER, ISEER, COP, BEE Star Ratings)

The energy efficiency of ACs plays a crucial part in selecting the Best A.C in India.

The energy efficiency of split-type AC is rated and expressed as Energy Efficiency Ratio (EER) or Seasonal Energy Efficiency Ratio (SEER).

Higher the ratio, the more efficient the appliance. Both are used as the basis for determining the (number, star, or letter) rating in energy labels.

Which are placed on split ACs in various markets.

Energy Efficiency can be measured in several different ways.

Though all involve, some comparison of the amount of energy input required to produce a unit of cooling output (or vice versa).

ACs move heat rather than convert it from one form to another, so standard measures of thermal efficiency are not appropriate for describing the performance of these devices.

Some important Tips from the Industry Insiders

  1. Having knowledge before the purchase could be handy, but It is recommended by the experts, that, not to give too much emphasis on the Energy efficiency ratings. These rating levels change after every two years. The ratings are usually different in the next cycle.


  1. Sometimes, buying an AC towards the early part of the new cycle can be tricky. Sometimes, what happens is that the AC manufacturers try to lure you or pass off the AC with a higher rating. This can also have an impact on the price of the AC as well. But be careful, if the rating become outdated in the new cycle, then it is of no use to you. You will only end up paying some extra bucks.


  1. The ratings only matter when you consider the EER. An EER of 3.19 and 3.20 does not make much of a difference as far as AC efficiency is concerned. However, the ratings change from 3-Star to 4-Star onwards

After Sales Service of the AC Unit

The main difference between a well-reputed brand and a normal brand is the after-sale service.

One thing not to be judgmental, or take into consideration for sure is, while selecting the after-sales service is whether they have their own employees to look after the product or they are using third-party service providers.

Nowadays, since most companies have outsourced, third-party service providers, are also quite good.


Timers allow you to program the AC to operate for a certain period before shutting down automatically.

This works best when you go to sleep and you want your AC to shut off automatically after a stipulated time frame.
