Best AC in India 2021 – Buying Guide

We all know what an air conditioner does for us. It cools down and maintains the temperature of our room according to the set functioning. The awareness about its features and operation has increased a lot with time amongst people. Though still, you need to be aware of its process, latest features and technologies before you invest a hefty amount in the right Air conditioner for your homes. After going through this buying guide, you will have a clear concept of everything related to ACs that will make purchasing an easy task for you.

How does an air conditioner work?

Air conditioner work on an elementary principle: Absence of heat is cold that means it removes heat from the indoors. Now let’s get into a more detailed explanation. An air conditioner works on three basic principles, i.e. evaporation, condensation and compression.

The AC unit compresses the gas and turn it into a high-pressure hot liquid. This hot liquid then flows through the condenser coil and cools down with the elimination of heat (liquid remains in high pressure). Here the expansion value converts the high-pressure liquid into low-pressure liquid. The fluid flows through the evaporating coils present in the AC.

In doing so, this absorbs the indoor heat and convert the liquid into a gas again. This heat absorption process makes you experience the cooling down of the room. Here you are required to tightly close the doors and windows to ensure that the existing heat in the room does not increase.

This above process keeps on repeating while ensuring to keep your room complete cool.

Types of air conditioners

Two types of air conditioners that get acclaimed in the Indian market, known as Window AC and Split AC. Both of these types do similar work, i.e. cooling and maintaining the indoor temperature.

Air conditioner typically consists of the following:

  • A compressor
  • A condenser
  • Evaporate coils (both inside out)
  • A fan and blower
  • A chemical refrigerant

Split Air conditioner: Split air conditioners come in two parts: condensing unit and evaporator coil. As its name both these units are split to complete the appliance job. Both the groups are connected through a line set “set of copper tubing” that transfer refrigerant from one group to other. The evaporator coil is placed inside the room, whereas the condensing unit gets placed somewhere outside the house.

  • Energy efficient
  • Quiet
  • Easy to use control panel
  • Attractive
  • Versatile (Can be placed anywhere in the room), also its outdoor unit can be placed anywhere outside your house including terrace, garage, or could be hung on exterior walls.
  • Installation (It needs to be installed only by professionals and may led to few damaging in your walls during the process)
  • Both the units need to be positioned within 30 meters that can be a con for some people.
  • Expensive. Can cost you 40-50% more than Window AC.

Window Air conditioner: Window air conditioners contain both the unit as split AC packed all together. When completed, it is a smaller unit than split ACs but performs a similar job as them. As its name window, AC is placed securely at the window of your room. Because of its compact packing, it consumes less space.

  • Budget friendly/less expensive
  • Easy to install
  • Easily transferable. Suitable for renters.
  • Can be only fixed on windows. It can be a task to remove grills, glass and net from windows first.
  • Hot air and Water dripping from the outer side can be end up in unwanted place.
  • In case of thin windows, the AC may require external support to stand firmly.
  • Consumes more power than split ACs

Difference between Split AC and Window AC

Split Air Conditioner
  • It comes in two units: An evaporation coil (indoor unit) and a condenser (Outdoor unit).
  • Makes less noise
  • Highly expensive
  • Installation slightly difficult
  • Comparatively difficult servicing
  • Occupies less space
  • Max. Capacity: No limit (However the max capacity available in India is around 3.0 tons)
Window Air Conditioner
  • It comes in as a packaged unit containing all the components together.
  • Makes more noise
  • Comparatively cheaper
  • Easy installation
  • Easy servicing
  • Occupies a little more space
  • Max. Capacity: 2.0 tons

Essential factors to keep in mind before buying an Air conditioner

  • SIZE: The most important thing to keep in mind is the size of the Air conditioner according to the size of your room. Purchasing a small AC for big space will make it tough to evenly cool down the room similarly a big sized AC will be a lousy pick for small-sized bedrooms. You can take reference from the table below:
  • Area demographics: The climate and demographics of the city where you live in is crucial for the type of air conditioner you would require. For places like Delhi and NCR where the temperature in summers touch the mark of 50 degrees C, you must go for the air conditioner with higher capacity. Whereas cities with heat in summer does not go more than 35-40 degree C, you can opt for AC with less capacity.
  • Room positioning: The air conditioner will work optimally for rooms that come in contact with direct sunlight throughout the day and effortlessly for places underground that are far from direct sunlight.
  • Daily usage: It would help if you looked at the refrigerant level as per how long you would intend to run the air conditioner throughout the day.
  • Budget: Without a doubt, this is the first thought anyone would generally have. Though if you are thinking to bring home an AC, you must make sure to keep your budget of at least RS 30,000-35000. With a low budget, you can go for a Window AC, and with the high budget, you can opt for split AC accordingly.
  • Power connection: You would need to look out for this while you get your ac placed. Considering where you plug it in, 10000 BTU or less – 15 to 20-amp circuit (of not shared with other appliances), 12,000 to 15000 BTU- 115-volt circuit (a separate circuit), and models with 18,000 BTU and above 18000 BTU 208 to the 230-volt circuit (an independent circuit).

BTU is the total amount of energy an air conditioner brings out. Take the reference as 1 ton = 12,000BTU.

  • After-sales service: Air conditioners get meant to be fixed and placed with a well-trained servicing person. Usually, the selling company sends an installer for doing the process. Make sure the brand you are going after provides an excellent after-sales service in your region.

This was about the primary factors now let’s dive straight into the technical terms and elements related to Air conditioners.

Air conditioner technology and features

  • Inverter technology: The inverter technology is a recent evolution concerning on the electro motors of the compressor. In this case, the compressor works at variable speed and never switches off. This varying speed draws in less power and works as a power-saving feature. The inverter AC technology is energy efficient which makes a makes a three* inverter AC works equivalent to 5* regular AC. Air conditioners equipped with the inverter technology can adjust the speed and tonnage according to the heat indoor.
  • Copper/aluminum coil: The coil in which refrigerant gas/liquid move inside is either made up of copper and aluminum. Most of the AC comes with the copper coil.
  • GoldFin condenser/technology: The AC condenser tube or coil are in constant of water which can lead to affect its performance. This technology does not allow the water droplets to settle down on the walls of the coil. With its low surface tension, the water slips down and prevent the loop from rusting.
  • Precision cooling technology: This technology gets designed to manage the high levels of heat (emanated by machines and without humidity).
  • Brushless DC motor: It contains a rotor in the form of permanent magnet and a stator in the way of polyphase armature windings. This motor does not include brushes, and the commutation gets done using electricity (by an electronic derive).
  • Precision cooling technology: This unique technology deters odor and deliver cleaner air. It also prevents the forming of bacteria and mould on heat exchangers.
  • Durafin technology: This technology coats up the heat exchanger with a combination of chromium and zirconium and strengthens its durability. It helps the outdoor unit remain corrosion resistant even in a highly corrosive environment.
  • Ocean black protection: It provides exceptional durability to the air conditioner in typical Indian demographics.
  • Refrigerants: Refrigerant is an integral part of the air conditioning system. It absorbs the heat from inside the room and delivers it outside. Refrigerant generally used in air conditioners in India are R22, R32, and R410A.

Different modes of operations

  • Econo mode: This mode enables the process by limiting the maximum power consumption.
  • Sleep mode: Sleep mode facilitate to ensure a decent temperature, less electricity consumption and minimal noise during night time.
  • Power saver mode: This mode shut down the compressor when the temperature reaches the set level. In this while, the fan keeps running to maintain the coolness. When the temperature exceeds a certain level again, the process gets repeated.
  • 6th sense cooling mode: Whirlpool is the only brand that features this mode in their ACs. Within the mode, the technology adjusts the fan speed by sensing the indoor temperature.

Meaning of the Star ratings

Whenever you come across an air conditioner, you may notice a five*, four* or three* ratings on it. This star rating helps in estimating the cooling efficiency of the AC. The start rating is generated by the BEE (Bureau of energy efficiency) for customer awareness. It comes marked as ISEER (Indian seasonal energy efficiency ratio). The ratio is the total amount of the indoor heat AC can remove when operated for cooling in an active mode to the total amount of energy consumed by the AC in the same period.

The more the rating, the higher is the cooling efficiency of the air conditioner. However, this also led to an increase in the cost of the appliances.
