Buying Guide For Best Air Conditioner In India
Different Types of AC
Split AC
a split Ac is split into two parts. One is the outdoor unit that is fixed outside the house, and the other is the inside unit fixed on the wall of your room, and copper pipes and electric cable connect these two units.
A split acid is considered technically more advanced because of its energy efficiency and higher performance than that of window AC. In recent times the consumption of split AC has risen drastically, and as a result company, these days focus more on it. Its only disadvantage is that it is expensive than window Ac.
Window AC
this AC comes in only one part and is generally mounted on a window and thus its name. This AC might be cheaper than the split one, but in the long run, it gives more expensive electric bills, and it produces a humming noise while operating. This type of AC is getting outdated these days and its production is also going down as many people don’t prefer this type of AC this day. That is why there is no window AC featured in the list of best AC in India 2021.
Portable AC
This acid can be transported from one pace to another like coolers but is more efficient than those. These AC’s are suitable for a small room and not big ones. Also, while using it, the water produced from dehumidification needs to be manually removed.
Multi Split Air Conditioning
Let say if you’re living in a triple bedroom flat or a Villa and want to have an air conditioner in each room. Image how much space it takes to place all three outdoor units and how much electricity it consumes?
The answer would be more. Ok, how to solve this issue? With a multi-split air conditioner system is right to opt for this kind of situation. Instead of multiple outdoor units, it works with only a single ac outdoor unit which can heat and cool all rooms in your home.
You can choose which ac to operate based on your needs instead of running all air conditioners. A multi-split air Conditioner system is highly energy-efficient and saves a ton of money.
At any time, you can add several indoor units based on your needs, but keep in mind with the addition of an indoor unit, you might need to change the capacity of the outdoor unit.
This system is flexible and works with a 4-way cassette, 1-way cassette, ceiling concealed ducts, wall mount, etc. It also offers 30% faster cooling, and you control using Wi-Fi from anywhere in your home.
Energy Star Ratings
While buying Ac, we have often heard about 3 star AC and 5 star AC, but what is this?
The star rating of an AC is its Energy Efficiency Ratio (EER). The EER of a 3 star ranges between 2.9 to 3.09, and that of a 5 star AC is more than 3.3. Now, this EER rating is not standard and may vary across places. To deal with this issue, the bureau of energy efficiency defined a new EER rating known as ISEER and stands for Indian Seasonal Energy Efficiency Rating. This rating has now been made mandatory for every AC.
Another term that we hear is COP. The cop stands for coefficient of performance. This value indicates the ratio of cooling or heating provided by a unit relative to the electrical energy required to generate it.
Cooper coil Vs Aluminum coil
One of the most decisive elements for the working of the AC is refrigerant. It is a chemical that continuously changes its state from liquid to gas and vice versa, and by doing it, it absorbs the heat that is present inside the room and dumps it outside, and sucks the outside air, and releases it inside. Now, this transfer of air takes place through the coil, and hence the type of coil used is very important.
Cooper Coil
these are generally expensive because they transfer the air proficiently and are more long-lasting and easy to maintain. Another notable feature is that cooper is anti-corrosive.
Aluminum Coil
these coils are much cheaper than the cooper ones, but the reduced price comes at a cost. They are less durable and ones damaged, needs to be completely replaced. Also, its efficiency of transfer is less and is prone to corrosion.
Inverter Vs Non inverter AC
If you ever went to a showroom to see an AC, the first thing that the salesman tells you is whether the AC is an inverter or not.
The most common misconception among people is that an inverter AC can run on an inverter when there is a power cut, but this just a myth. An inverter AC uses the inverter technology to operate.
But what is inverter technology?
In a non-inverter AC, when a person switches on the AC, the compressor begins to run at full speed and does so until the room temperature is equal to the temperature fed to the AC. After reaching the temperature, the compressor shuts off completely and then again operates at high speed when the temperature rises again. So it turns on and off again and again.
Whereas in an inverter AC, the fan operates at the highest speed until the desired temperature is reached, and after reaching also, it runs at a very low speed. Doing so avoids the repeated cycle of switching on and off, and this cycle consumes a lot of electrical energy. Hence, inverter AC saves energy by doing so.
Looking at all the aspects, it is advised to always go for an inverter AC as it is better to purchase in the long run.
Various Types Of Refrigerants Used In AC
As I told you earlier, the refrigerant is a very important aspect of the AC because the entire cooling of the room depends upon it. Now various types of refrigerants are used these days. Let us look at some commonly used refrigerants:
CFC
it stands for Chlorofluorocarbons and is also known as R12 refrigerant. This refrigerant is one of the most effective ones and cools the room in a brief period. But this is the most criticized one also as it causes significant depletion to the ozone layer. As a result, the CFC production was discontinued, and today no AC in the world uses R12.
HCFC
it stands for Hydrochlorofluorocarbons and is also known as R22 refrigerant. After CFC got banned, HCFC started to be produced at a high rate. This is one of the most widespread refrigerants used in the Indian market, and most AC’s uses this refrigerant. But this refrigerant is also not ecofriendly and has a pivotal role in depleting the ozone layer. As a result, there is a talk that this refrigerant is also going to be discontinued after few years. So, it is advised that people should not buy an AC which uses this refrigerant.
HFC
it stands for Hydrofluorocarbons and is also known as R32 or R134 refrigerant. This is a relatively eco-friendly refrigerant and causes no harm to the ozone layer. There is a gradual change today with the world shifting from other refrigerants to this one. Many AC’s in the market today use this, and if you want to buy an AC, try to look for the one having this refrigerant.
HC
it stands for hydrocarbons and is also known as R290 refrigerant. This is the most environment-friendly refrigerant in the market, and as a result, many companies are looking to go for this alternative.
AC Refrigerants Comparison
| Refrigerant | Ozone Depletion Potential (ODP) | Global Warming Potential (GWP) |
|---|---|---|
| R-22(Chlorodifluoromethane) | 0.005 | 1810 |
| HFC-32 or R-32(Difluoromethane) | 0 | 675 |
| R290(Propane) | 0 | 3 |
| R600a(Isobutane) | 0 | 3 |
| R134a | 0 | 1430 |
AC Low Gas Detection
When ac gas level is low, ac can’t run at full potential making your room hot and uncomfortable.
The Ac lows detection feature automatically indicates when the ac refrigerant is less than the recommended level. In LG air conditioners, when the refrigerant below 40%, it will show CH 38 sign in ac front panel.
Whenever you notice this indicator, call the ac technician and refill the refrigerant as soon as possible.
Air conditioners, refrigerant gas need not be changed often as they serve the entire life span of AC, In sporadic cases, we need to refill the gas, if not changed promptly it will cause oil fire, insulator melting, PCB fire, rotor burnout.
Dual Inverter AC
Unlike a conventional compressor with a single rotor, dual inverter ac contains two rotors that operate at higher speed maintaining stability. Due to this feature, it can achieve 40% faster cooling than conventional ac compressors.
This compressor is also referred to as a twin rotary compressor and contains the following parts such Accumulator, Rotor, Shaft, Motor, Muffler, Cylinders, Suction pipes, Rollers.
Motors used in this new inverter have more efficiency about 3 percent than the normal compressor motor, due to this overall compressor efficiency has been improved up to 8-16%.
Some of the significant differences between Dual inverter and Single Rotor compressor are
As the single rotatory compressor operates with a single-cylinder, compressor electricity supply reaches up to 70Hz. while the twin rotary compressor operates with the dual cylinder and two rotors resulting in Higher energy efficiency (30Hz) within a short time.
These compressors have less vibration as the twin rotors are positioned at an opposite angle creating perfect balance while rotating. instead of pushing the entire force in a single direction causing more vibration like in a single rotary compressor.
Scroll Compressor
A Scroll compressor can compress the refrigerant more efficiently than a conventional reciprocal or centrifugal type of compressor. It uses two interleaving scrolls to compress the fluids. If you cut open this compressor on top, it looks like an archimedean spiral.
There are two scrolls in this type of compressor. One is fixed, and another orbit around it in constant motion. Gases absorbed in the compressor chamber are passed through these scrolls creating compression as pockets become smaller and smaller towards the scroll center.
Once the refrigerant gas is compressed, It is discharged through a port on the compressor’s top side. You can find this compressor often used in vehicles, heat pumps, and ACs due to its design and reliability.
Variable Speed Compressor
In a Variable Speed Compressor, the motor’s speed is controlled using an inverter, which achieves precise control and quiet operation of the compressor.
Brushless permanent magnet motors in these compressors allow the compressor to adjust the cooling loads as per requirement. Intermediate discharge valves in this variable Speed Compressor boost the efficiency across various conditions.
Scroll elements are much more optimized to provide better performance; a positive displacement pump located at the compressor’s bottom ensures maximum reliability.
These compressors’ main benefit is that they make notable savings on your power bills up to 40% in a year. They are highly energy-efficient and consistently fulfill the temperature demands, unlike shutting On/Off in standard AC’s.
With their superior cooling and heating, they offer up to 25 plus Seasonal energy efficiency ratio(SEER) and 13 plus Heating Seasonal Performance Factor (HSPF)
Bluefin Technology
The main function of an AC is the transfer of gas and liquid from inside to outdoor and vice versa. This transfer mainly takes place through the coils, and thus the coil becomes an essential part of the AC.
It has been seen that in the long run, these coils are susceptible to corrosion, and hence many preventive measures are taken to stop this corrosion. One of these methods is the bluefin technology.
In humid regions like India, there is a continuous deposit of water in the coils, which may lead to corrosion, and the best way to stop this is to cover the coil with a particular paint called epoxy.
This coating of epoxy prevents materials like salt or water from accumulating on the surface, and this coating is known as bluefin technology.
Auto Clean Feature
When you buy an AC, one of the hardest parts is maintaining the AC. Your AC requires regular cleaning, and failing to do so can cause harm to your AC, and hence this process becomes tiresome.
Hence to remove this problem, the various companies came up with a feature known as auto clean.
This auto clean feature helps remove moisture from the inside unit of the AC, which, if it remains there, can lead to the growth of harmful microorganisms that may damage your AC. The auto-clean feature works by evaporating this moisture. This option enables the AC to provide you with a better quality of air.
This system should be used after every two weeks, but in a moisture-ridden country like India, it is advised to use this feature every week for the proper functioning of your AC.
Anti Corrosion
In most of our AC’s more than one metal is used in making the device. This is a very economical option but is not at all good for durability. When more than one metal is used, the device becomes more susceptible to corrosion, and even if you use a single metal, corrosion will eventually occur.
In a moist country like India, galvanic corrosion is very common in AC’s, and when this happens, it can lead to gas leakage, and one needs to replace the entire condenser to fix it.
To prevent this problem, companies put an anti-corrosive coating over the ACS. Generally, epoxy coatings are given, and these epoxy coatings are mainly of two types is Bluefin coating and golden coating. However, this costs a bit more but will save you a lot in the long run.
Anti-Bacterial Filter
The air present around us has a lot of microorganisms in it, and some of it may even be harmful to us. When we are using an AC, the room is entirely closed, and there is no room for ventilation which makes the inside air more prone to the growth of bacteria.
The antibacterial filter is just another kind of purifying filter. This filter is mainly designed in such a way that when it sucks in the outside air, it uses a contraption design to get hold of the dust particles and then kill the harmful bacteria or other microorganisms present in it. This is done by using positively charged particles to attract the negatively charged particles.
By removing the dust particles, this filter increases the Ac’s life span and increases its performance. It is also better for asthma patients and kids, as they get better quality of air. The lifespan of this filter varies, and it needs to be replaced after it is damaged.
AC Filter (PM 2.5 filter)
Pm 2.5 are basic dust particles whose size is less than or equal to 2.5 microns. It is mainly emitted from power plants, vehicles, or by burning wood. These are very harmful as they are very light and stay in the air for longer durations. If you contact these particles, it can cause problems to your respiratory system by making plaque deposits on your arteries that may harden it.
This article is also one of the crucial factors in causing heart attack and stroke. Hence your AC needs to look for these particles when it pumps in the outside air.
Pm 2.5 filter is a special filter designed to trap even the finest of impurities and provide you with good quality air after removing the pollutants.
Seeing the rising levels of pollution these days, it is essential to look for AC’s which come with a PM 2.5 filter. This may cost you a bit but is very good for your health.
Cool Roof Paint
If you’re your rooftop is directly exposed to the sun, then you might notice hot waves swirling around you as soon as you turned on the fan.
During the summer season, this situation would be even worse even though ac is running at the lowest temperature and it takes more time to cool the room.
Paint your rooftop with cool roof paint, which acts as a solar reflective coating and reflects all the sunlight to the maximum extent as it contains high SOLAR REFLECTANCE INDEX (SRI).
Price
Well, the price of any product is our primary criteria in buying it. The first thing we notice in an AC is the price tag. Well, AC is a costly investment but is a one-time investment.
The cost of an AC depends upon several factors, and what do you want in your AC. One of the main factors is the energy efficiency rating of the AC. A 3 star AC is cheaper than 5 star AC. Also, features like whether various types of filters are there do not affect an AC’s cost.
It is recommended that a person should buy a 5 star AC. This may be a costly alternative, but it may save you a lot on your electricity bills in the long run. Also, these days there is a new trend which is smart AC.
A smart AC can be connected to Wi-Fi and lets you access the AC through your phone. This option is a little costly but provides a lot of comfort and easiness for you. So it is up to a person what features he wants in his AC and pay the price according to it.
Installation And Maintenance
After you buy an AC, the next step is its installation. An expert is generally allotted to a customer from the company itself, and they usually come one to two days after the delivery of the product. The installation of an AC is a simple process and takes a few hours.
First, the outdoor unit is placed in a suitable place with a proper drainage facility. Then the indoor unit is placed in your desired location. Then the two units are connected through a copper coil and pipe, for which a hole is generally made in your hole. After this, the technician checks for any faults in your AC, and if not found, he sets up the AC, and then you are ready to go.
Maintenance, on the other hand, is a long-term process. Ac is such a device that needs maintenance regularly and at least once a year. You need to clean the AC every month properly, and once every year, you should call a mechanic and let him open up the AC and take a look at it. This will ensure the AC’s smooth functioning and make it last long and sure it should, keeping in mind the money you are investing in it.

How to calculate british thermal unit required for a room?
Its the amount of energy required to heat 0.45KG of water by 1° Fahrenheit. If you want to know how many BTUs are needed to cool or heat the room, multiply your room’s cubic feet with 5 BTUs.
Room Cubic Feet =Length x Breadth x Height
If your room is about 10 X 10 x 12 (Cubic Feet)
10×10=100
100×12=1200 Cubic Feet
1 Cubic Feet= 5 BTUs
so
1200×5=6000 BTUs
So it takes around 6000 BTUs for a; 10 by 10, 12 feet ceiling room. If there are no windows in your room and it is a bit compact, you can take 4BTUs per 1 cubic foot instead of 5 BTUs.
When you’re buying an air conditioner for your home, calculate the required BTUs above the formula or method.
Note: The accurate required BTUs may depend on a lot of other factors like the number of windows in the room, Insulation of walls, etc.
