Air conditioners have become a necessity in India. If you are also looking for a way to get relief from the scorching sun during the summer season, buying a split AC can be very helpful.
When it comes to selecting the best split AC in India, here are a few major factors that you must consider.
Cooling capacity: The cooling capacity of an AC depends on the size of the room.
The ideal Thumb rule is 600 sq. ft/ton
An AC with 1-ton capacity can cool up to 600 Sq. ft room (i.e., Kids bed Room) whereas an AC with 1.5-ton capacity can cool upto 1000 sq.ft room (i.e., Master Bedroom).
Power Consumption: The Split air conditioner models are 20% more efficient than other compressors and window acs. These models come with a twin rotary compressor and a permanent magnet motor.
For Efficiency: The efficiency of an air conditioner is measured as the ratio of work performed to the total energy consumed. It is measured in SEER i.e. seasonal energy efficiency ratio. If you are looking for a device that will help you save power, you can buy ACs with a 5-star rating.
Some other factors that play a major role in deciding the performance of an AC are adjustable controls, cooling speeds, noise levels, etc. We have explained them in detail in the Buying Guide below.

One must have the basic idea of choosing air conditioners that best matches with their requirements. The key factors include conditioner type, room size, power consumption, and cooling speed that greatly influence the performance of the device. Read below given AC buying guide 2019 to know how these parameters help in bringing freshness in your room.
Type of conditioner is the core factor that you should look into before purchasing air conditioner. As we have completely focused on split air conditioners in this context, we have given complete information about the split types. They are categorized in 2 different ways…
Mini-split
Mini-split or ductless air conditioners have major applications in homes, commercial buildings, offices and institutional buildings. It can be a great asset if you install on small apartments where is there is no use of central air conditioners.
This mini-split or ductless systems are further classified into 2 types.
Single-split AC
Usually the single-split AC supplies the conditioned air to a single or few rooms in a house. They spread cool air to a maximum of 8 rooms using a single outdoor unit. It is often called as multi-zone systems as it adopts to indoor unit styles like wall-mounted, ceiling-rested or horizontal ducted.
The main advantage of using ductless system is that it is of small size and very flexible to heat or cool the individual rooms. In addition to this, the compressor and heat exchanger are separated at a distance than merely lying on 2-diffferent sides of the same unit.
They offer very high efficiency and the only minor cons of this product is the cost which is 30% more than the traditional systems. And even the installation costs are too high.
Multi-split AC
Multi-split AC is a convectional split system that is further divided as evaporator and condenser units. It allows the heating or cooling process to several rooms using a single external unit.
In this, all the individual systems are connected to the main unit (external) with the basic operating principle for retaining coolness in rooms, offices, and other commercial places. And check which condenser is good for split AC as it is responsible for automation with the locking valves for regulating the halocarbons to the indoor unit.
Earlier multi-split models have only 1 control system that allows the users to set the conditioning for each room. Now the market has more powerful multi-split systems that can be operated individually.
On a contrast, single split AC produces 9,000-36,000 BTU whereas multi-split delivers 60,000 BTU’s per 1 hour of cooling.
Central-split AC
Central ACs or ducted system offers coolness to the entire house or large commercial buildings. It is very much capable of delivering moderate temperatures with the addition of air louver-controllers.
In this, the heat-exchanger is fixed on the central unit to evenly distribute the chillness especially in summer season.
Second important factor is the power consumption by the split air conditioner. Regular models are equipped with less number of features to save the power. So to minimize the power utilization, the advanced models are equipped with twin rotary compressor that features permanent magnet motor which is 10% more efficient in saving power than other convectional compressors.
When you make a purchase, you should check whether the split air conditioner is compatible with the size of the room that you would like to have it in. For small-sized rooms, the ac can be 1 ton and for medium or big halls 1.5-ton air conditioner is mostly preferred.
Select the desired split air conditioner as per the requirement of your room. Be sure to close windows and doors when you switch to AC than simply running a fan.
Tonnage of an air conditioner is based on size of the room. It is the key feature of a split conditioner which also determines the price of conditioner. As most of the conditioners are rated by tonnage, it is equal to 12000BTU per hour for an ideal choice.
The 1-ton capacity AC can cool up to 1000 cubic feet volume, whereas 1.5 ton can cool up to 15000 cubic feet. So it’s better to go with the 1.5-ton AC as it is very much convenient and comfortable to bring chillness in medium-large sized rooms.
Given below table is completely based on 2 factors- size of the room and tonnage of air conditioner. Both of them are in direct proportion to each other. If the size of the room increases, then the capacity of the split air conditioner also increases and vice versa.
| Room size (Square feet) | Tonnage capacity (Ton) |
| 90 | 0.8 |
| 120 | 1 |
| 180 | 1.5 |
| 220 | 2 |
Next one is the Cooling speed that ensures how fast a device can cool the room. It may vary from brand-to-brand, prices and the cooling technology it employees. But most of the top-brands with good ratings possess high cooling speed and the poor cooling speed in traditional models. On an average, a regular conditioner may take 4-6 hours, but the top notch models just take less than an hour to cool the room completely.
As the conditioner internally has fans to perform a specific task, they produce some noise. The level of noise production in a conditioner determines whether you can buy the product or not.
Usually we feel bit irritative due to the noise produced by the fans especially at night times. It may even spoil your mood or disturbs the sleep. For them, opt for noiseless conditioners that come at affordable prices.
If you aren’t that much bothered about the noise generation, then you simply buy the traditional models or latest models with smart options. It’s up to your choice.
Efficiency is usually defined as the ratio of work performed to the total energy consumed and is measured in SEER- seasonal energy efficiency ratio.
SEER =Cooling output during the cool season to the total input energy.
If the power consumed is higher the amount of heat removed per unit, the greater will be the efficiency of the air conditioner. Lots of the standard ACs have 3-star rating whereas high efficiency conditioners have 5-star rating.
It is completely based on the power consumption and the cooling performance it delivers. If your main priority is to save power and also operate greatly then go with the 5-star ACs.
Build quality expresses the capability of a product to which its functionalities are extended. For an ideal split air conditioner, the product quality is fantastic.
When you look at the split air conditioner, its outer body and inside is made with the copper material.
Some manufacturers use aluminium or a combination of both aluminium & copper to cut down the prices. Using a copper or aluminium doesn’t make much difference, but when compared; copper material is capable of delivering high efficiency results without any negative effects on the conditioners.
Cost of split air conditioner is the another important factor you should look for. It is available in almost every budget range to satisfy the consumer needs.
Here in this article, we have focused on premium products and the basic models to give you clear idea about the difference in the functionalities, operating modes and the smart options it possesses.
These days everyone is showing interest in purchasing the smart-devices as they can be controlled via smartphones or performs the tasks by setting timer option. So, you must plan your budget before buying a split air conditioner, otherwise it will totally waste of your huge investments.
Given 12 below are some of the outstanding features that most of ACs are equipped with. Read on to know how each of it is beneficial in improving the performance and also allows the users to handle the conditioner very comfortably.
This is another useful mode that helps to reduce the humidity and dampness in air inside the room. It makes you feel comfortable and acceptable. That’s why this special feature is very useful during the cool days of spring and fall.
Regular models need to be turned off manually. But now the smart ACs are programmed such that they can be operated automatically to save lot of energy. It is actually a 24-programmable timer which allows the users to customize the time settings or schedule according to his choice.
You are much worried about ACs and don’t want to be misused in your absence, then this digital lock feature will allow you to do so. It helps to protect the settings with just a lock option so that no one can change them.
It is just like a ventilation to let the air to pass through without keeping unwanted elements like dust, gases, and debris. They have fixed number of blades and are mounted on a frame for greater functionality.
You can adjust the louvers manually or remotely to point in a desired direction and also control the specific task when required.
The pre-coated aluminium fin is the main component in heat exchanger and in the process of exchanging air, it blocks the airflow in between the 2 fins. It is mainly responsible for preventing rust and corrosion which accounts to the long-lasting nature of an air conditioner.
It is better to choose the split AC that comes with multiple fan speed option to ensure that the airflow distance can cool down the room very quickly. More the fan speed settings, the better cooling in a room.
The auto-fan speed functionality can be explained with the working of compressor. When the compressor is shut down, the fan speed will automatically slow down and vice versa.
The auto-clean function is all about removing the dust particles present on the AC filter. Its working is as simple as that it gets command from the controller, to eliminate the dirt using a brush attached to the stainless steel plated filter.
The main advantage of using auto-clean function in an AC is that it always keeps the device free from moulds and bacteria. Also, helps in lowering the power utilization thereby making the best energy efficient AC in India.
All split air conditioners come with adjustable thermostat to control the temperature delivered by the AC in different standard modes such as Auto, Cool, Heat, and Dry. To have such wonderful options, you need to purchase the latest model ACs that comes with smart features at reasonable prices.
This is a highly functional and important mode that automatically increases the temperature of the room gradually to a comfortable level while you sleep. This mode helps to save power and reduces pressure on the AC.
Here are some possible ways to save energy using an air conditioner.
If an air conditioner has louvers, adjust them towards ceiling while cooling and when heating keeps towards the floor.
According to the mounting location, the split ACs are classified into 3 types- Wall mount, ceiling mount and floor mount. Each of them are explained in detail.
Wall mount ACs are the most popular ACs in which the indoor unit is placed inside the room. It is much suitable for small rooms that can cool uniformly.
Floor mount is often called as Vertical or tower split air conditioner. These are in great demand where you cannot mount AC on walls or wooden-blocks. It is more expensive than wall mounted devices. And hence the floor mount split ACs are comparatively less popular for homes.
Ceiling mount is an another type of split AC which is also known as Cassette type air conditioner. They look absolutely fantastic and the price is too high compared to the wall mount and floor mount air conditioners.
Compressor is a device that increases the pressure of a gas by reducing the volume. And air compressor is one of its specific type.
In this context, the compressor is the most essential part of an AC that helps in cooling the refrigerant and also determines the performance of air conditioner.
The conditioners with reciprocating type of compressors are very less expensive that has high cooling capacity and runs for a long duration. These are not efficient as the one equipped with rotary compressor.
Reciprocating compressors are stationary-portable, single-multi stage, that helps to energize the electric motors.
Small compressors with 5-30hp (horsepower) is seen in automotive applications and 1000hp in large-scale industries & petroleum machines.
Rotary type compressors are better than reciprocating types as there is a reduction on pressure of the gas. They come in a compact design and the cost is too high. It just need little maintenance cost to run on long-term basis.
It is a single stage helical or spiral lobe air compressor that consists of 2 rotors to cool the air without any valves. Since the cooling is done inside the compressor, the working components never experience the extreme temperatures.
Scrolling compressor is a combination of scroll pump or scroll vacuum pump. It has 2 interleaved spiral like vanes to pump either liquids or gases. Its operation is very smooth and high reliable than other types.
They are generally seen in ACs that have cooling capacity above 2.5 tonnes. The key features of this compressor includes the operating voltage, running costs, low sound and vibrations. The working of this compressor is such that one of the scroll is fixed and the other orbits eccentrically without rotating to trap and pump.
But for normal home purpose, maximum of 1.5-ton AC is alone sufficient to cool the room.
Before selecting the location for an air conditioner, you must consider several factors like…
1. How to select the right-sized conditioner for your room?
A quick and easy method to analyse is by using the square foot method. It may not give the exact results, but helps you to follow certain guidelines by considering ceiling height, shade, size, and room occupancy.
For instance, the 400 Sq. ft house requires 1 ton cooling medium, 8-inches of ceiling height with tight doors and windows.
The simple formula used to find the square footage is by measuring the length and breadth and then multiplying the both. For a room with length 10-feet and 12-feet breadth has the resultant of 120Sq.ft.
2. Which one to buy-split or window AC?
The major difference is seen in the hardware equipment as window AC comes in a single unit and 2 units for split AC. In window AC, all the parts like compressor, motors, pipes, and heat exchangers rests on a single system. And the split system is supported with indoor and outdoor units.
The split air conditioners produce very less noise compared to window AC and also is very easy to install, making it more efficient to buy these days.
3. Is it necessary to use voltage stabilizers in an AC room?
Yes, it is necessary to have a voltage stabilizer to run AC in your room. Because the power supplied to every individual house may not be 230V and there may be slight variations. So, using the stabilizer, will control the flow of current by using the negative feedback network.
4. Why should you choose split air conditioner?
Given below are the major factors that helps the users to have a kick start with the split air conditioners.
5. How to know that my AC is highly energy efficient?
To know how energy efficient the system is, you need to know the factors like BTU, SEER, and HSPF that explains the power utilization in an AC.
What is BTU?
BTU is the acronym for British thermal unit. It is a traditional unit of heat that is required to raise the temperature. As joule is the measure of heat, BTU can be expressed as how much energy it takes to produce the heat per hour.
1 BTU = 1055 joules
In the given below table, we have listed the room size in square feet and the number of BTUs required.
| Room Size (Square feet) | BTU Required |
| 150 | 5000 |
| 300 | 7000 |
| 500 | 11000 |
| 1000 | 18000 |
| 1200 | 21000 |
| 1400 | 23000 |
| 1600 | 25000 |
For your easy understanding, we have also given the conversions of BTUs to other energy measurements.
1 BTU is approximately equal to 1.054 Kilo Joules/0.2931 Watt hours/253 Calories or 0.25 Kilo calories
What is SEER?
SEER is abbreviated as Seasonal Energy Efficiency Ratio. It determines the efficiency of an air conditioner and is expressed as the cooling output during a typical cooling-season to the total input electrical energy during the same period of a unit.
Higher the SEER Greater the Energy Efficiency.
For example, if there is 5000BTUs of air conditioner unit with SEER of 10BTU/W-h, operates for 1000 hours i.e. 8 hours a day for 125days=125*8=1000hours.
Then the annual cooling output will be 5000*8*125=5000000BTU/year
By considering SEER of 10 BTU/W-h Annual power usage will be=5000000/10 =500000W-h/year
What is HSPF?
HSPF- Heating seasonal performance factor. It is a term used to measure the efficiency of air source heat pumps.
HSPF is defined as the ratio of output BTU heat to the power used in heating season (watts-hours). A system is said to be high energy efficient if the HSPF is more than or equal to 8.
To calculate HSPF for a heat pump of 120000000BTU during the season by consuming 15000KWh.
HSPF=120000000/(15000*1000) =8
When compared to the less efficient system, the more efficient heat pump utilizes less energy thereby increasing the energy savings and life of the system.
6. How does split air conditioner work?
To make the split air conditioner work, the 2 units are connected through pipes (made of copper or aluminium). Initially the gas is fed to the compressor and is pressurized. Now, it is passed through the pipes to condense into liquid state. During the process of conversion from gas-liquid, the pressure is completely minimized.
Now, the indoor air is captured by the unit and is passed through evaporator coils. It completely cools down and is forced back via blower. The air continuously circulates in a room until it reaches the thermostat level. When it is done, it automatically shuts down.
7.On what factors the power consumption of split air conditioner depends?
The power consumption by split air conditioner may vary from brand to brand, model, living area, filters used and finally the tonnage capacity. All these factors are responsible for the utilization of energy. If any of them have trouble, then trust me you are going to pay huge amounts to the electricity department.
8. What is the main reason for an AC to produce sound?
Noisy air conditioner is so annoying and there are several reasons like worn out compressor, faulty fans, motors or the belts. The noise produced in an AC indicates that something wrong is happening inside and you need to immediately rush to the service centre. Else, the situation may be worsen and cannot be fixed.
9. When should I replace old conditioner system?
The time to replace the old conditioner with the new ones is the time when you see the conditioner constantly undergoes several repairs or have completed the duration of 5-10 years. It can be due to the malfunctioning of filters, fans, or the motors.
Sometimes even though you replace them with new ones, still the problem arises. When you give system to the service operator, they might impose high charges which you cannot bear. Rather buying the small parts for several times in a year, it’s better to have new conditioner as it comes with the lifespan 10-years.
10. How long does a new air conditioner system lasts?
The life expectancy of a new conditioner is too good to be true and may vary from brand to brand. These days the conditioners are expected to last from 10-15 years. But still it depends on how well you maintain the conditioner in a room. If you maintain the system properly or in a right way, then it can even last for 5 more years.
11. How often you should clean the filter?
If you newly purchased the air conditioner, then it’s better to clean the filter for every 2-3 months. Once you find the filters that aren’t working properly then immediately change the filters as it may result in huge power loss.
And if you are using the conditioners over a year then you must clean the filters for every 2-3 weeks as old ones have more chances of damaging the product performance. Sometimes it may even depend on your indoor pollution levels and the pre-filters are subjected to regular cleaning in warm water.
An air conditioner is one of the most important things to have in your house. It is quite important in the harsh heat of summers here in India.

Therefore, you might also be interested in buying an AC for your house.
But there are various factors that you have to look into before buying one. This includes things like cooling capacity, energy consumption, warranty, condenser coil, and various other features. Due to this, choosing the best AC for your home or office can be a bit difficult. If you are still not able to select the perfect AC for your needs, here are some of our recommendations:
