How to Select Best Air Conditioner in India – AC Buying Guide

Home » Blog » How to Select Best Air Conditioner in India – AC Buying Guide

A good home air conditioner not only provides relief from the summer heat but also provides air purification throughout the year, humidity control during the monsoon, and heating during the winter. With so many options available, knowing how to choose the best air conditioner for your home will assist you in making an informed decision.
Air conditioners with similar capacities need not necessarily have the same power consumption. Some ACs, therefore, sport a better ISEER (Indian Seasonal Energy Efficient Ratio) rating than others. Unfortunately, these air conditioners are also expensive. In such circumstances, you must decide whether purchasing the more expensive but more efficient variant is the best option.

Make it a point to shop for a split air conditioner or window air conditioner this summer to reap the benefits. This is the best time to purchase an air conditioner for your home.

Take a quick look at the tips you should keep in mind when choosing the best air conditioner for your home before you start shopping.

1. Capacity

The size of the air conditioner that you want to buy is completely determined by the size of the room or house and the limit of the cooling. For your air conditioner to run efficiently and last longer, it needs to be the proper size. The capacity of an air conditioner is determined by a variety of parameters, including room size, location, and the number of people. Before you buy an air conditioner, figure out how much tonnage or BTU you'll need for your home.

The cooling capacity of an air conditioning system is measured in tons, with one ton equalling the amount of heat required to melt one ton of ice in 24 hours. It is critical to select an air conditioner with the appropriate tonnage for the size of your room. A 1-tonair conditioner is more than enough for rooms under 130 square feet. A 1.5-tonair conditioner, on the other hand, is better suited for a room of around 185square feet.

2. Energy Efficiency

When making a decision, one of the most important factors to consider is energy efficiency. Given the high cost of electricity, we'd prefer an air conditioner that provides maximum cooling while using the least amount of energy. The start rating of the device, which is standardized by the Bureau of Energy Efficiency (BEE), is the metric for the energy efficiency of an air conditioner. Higher the star rating, the better the energy efficiency. As a result, when compared to a 1-star AC, a 5-star AC will use the least amount of energy. Inverter series air conditioners, on the other hand, provide higher efficiency at lower star ratings than conventional air-conditioners.

3. Budget

An air conditioner is a significant investment in your home, so it's critical to know how much you're willing and able to spend. For how long do you stay in your current home? Do you own this property? Ask yourself these questions because it's pointless to install a ducted system if you're planning on relocating soon. An air conditioner is a valuable asset, and you should consider all financial variables before making your ultimate decision.

4. Size of the Room

The size and capacity of the air-conditioner should correspond to the size of your room. Choose an air-conditioner with the appropriate cooling capacity for the size of your room. It will not be able to provide proper dehumidification if it is larger; a unit with too high a cooling capacity for space will turn off and on too frequently, and a smaller unit will cost you more in terms of energy consumption if it is smaller.

5. Exposure to Direct Sunlight

The amount of direct sunlight that reaches the area that needs to be cooled is a significant factor. A room that receives direct sunlight requires more cooling than a room that does not receive direct sunlight. Leverage on the machine's tonnage could only be used in areas that aren't exposed to direct sunlight.

6. Product Price

While today's air conditioners are jam-packed with features, one should opt for one that is equipped with technology that caters to the user's needs. It's critical to stick with a well-known brand that offers all necessary features at a reasonable price.

7. Brand

Choosing an air conditioning system from a well-known brand is a safe bet. This gives a sense of security and assurance about the air quality. It also ensures that if something goes wrong, you will be covered by a good warranty and service. If you have friends or relatives who are using or have used a specific brand, don't be afraid to ask them for their opinions. This is yet another smart move you can make to avoid squandering your money on less trustworthy and low-quality brands.

8. Air Quality

When purchasing an air conditioner, keep the indoor air quality in mind. It's critical to have an air conditioner with a decent filter if you want to improve the air quality in your home. The air filters in your air conditioner help to remove dirt and germs from the air, as well as smoke and odors.

A good filter not only cleans the air but also guarantees that dust and dirt do not reach the evaporator coil, enhancing the performance and energy efficiency of your air conditioner. Also, to reduce humidity in your room, seek for an air conditioner with a good dehumidification unit. Better cooling and comfort are also provided by air-conditioners with good dehumidification systems.

9. Key Components

A blower fan is an important part of an air conditioner that distributes air throughout your home. The larger the blower fan, the more powerful the airflow. Another component that helps to speed up cooling is condenser coils. Condenser coils should be able to facilitate heat exchange while also being anti-corrosive. Another important component is protective capacitors, which provide fire safety in the event of a disconnection or a circuit failure.

10. Cooling Speed

We can achieve variable fan speeds with air conditioners that have a thermostat and multiple fans, lowering overall power consumption. Airflow and swing settings are now available on most air conditioners. These options allow the user to customize the cooling levels of the air conditioner to his or her preferences, as well as contribute to there duction of the air conditioner's noise level.

11. Installation and Maintenance

It's critical to have your air conditioner installed properly by an authorized dealer if you want to get the most out of it. Split air conditioners have a compressor, whereas window air conditioners are simply attached to a window. The installation process should be flawless, and the air conditioner should be maintained and cleaned on a regular basis. Follow your dealer's recommendations for how often the filter and other AC components should be serviced.

Air conditioners must be serviced on a regular basis to ensure that they remain in good working order. These units can collect dust, grime, and debris over time. This can clog the filters and reduce the efficacy of the unit. Be sure to clean your cooling system once a year. Wash the air filter with soap and water if you have a window unit. For central air: schedule regular professional tune-ups.

12. Additional Features

These days, air conditioners have a variety of subtle advances to entice customers. These optional features can betaken into account when making a decision, but only after the primary requirements have been met. Sleep Mode, an auto-cleaning feature to keep moisture away, 4-way swing, Quick Cool, Jet Cool, and even Mosquito Away for regions with a lot of mosquitoes are among these features.

Before purchasing an air-conditioner, you should consider the brand's history, aftersales, and the quality of its service. An air conditioner is a complicated piece of equipment that requires professional maintenance on a seasonal basis. If the brand of air-conditioner you're contemplating has a bad service network and aftersales, you might want to examine other options.

If you’ve decided to buy your first ever air-conditioner, it’s time to understand the various types available in the market. Choose accordingly as per the pros and cons are given in the following.


What Are the Types of Air Conditioner System?

Air conditioners come in a variety of shapes and sizes, each with its own set of advantages and disadvantages. This guide will get you up to speed if you're seeking to buy an air conditioner but don't know where to begin. It will go over the many types of air-conditioners and the essential features of each to help clarify things.

Even within the same class, each air conditioner has a broad range of quality and functionality. A new, energy-efficient multi-head split system may be more efficient than an older multi-head split system; thus, it's crucial to research each model thoroughly. The energy rating star system is a wonderful method to assess how much energy air conditioners use, but the capacity outputs and inputs provide even more information.

1. Window AC

They're large because all of the components must fit inside a single chassis. This also means that a consumer has fewer things to worry about, resulting in the entire unit being cheaper than the rest.

For this reason, such air-conditioners are also known as mono-blocks. To mount a Window AC on a wall, you'll need walls that are 9-12 inches thick. If your walls are thinner than that, you'll need an additional support structure, or you should look for a thicker wall.


  • Low Cost
  • Easy to install
  • Mono-block design


  • Noisy
  • Need a thick and sturdy wall for mounting

2. Split AC

Split air conditioners are better than window air conditioners because the compressor and heat dispensing coils are separated into an external unit that sits outside your home. Split air conditioners are more difficult to maintain because maintenance personnel must access the external unit.

There are also some restrictions on the distance between the internal and external units that can be installed. The further apart the two are placed, the less efficient the combination becomes, so keep it as low as possible. These air conditioners can be installed up to 40meters apart as long as the interconnecting tubing is well-covered. Cassette air conditioners are a type of split air conditioner in which the internal unit is mounted on the room's ceiling.


  • Expensive
  • Makes less noise
  • Can be installed on any wall


  • Higher risk of coolant leaks

3. Portable Air Conditioner

Portable air conditioners are a convenient alternative to a larger air conditioning system and are perfect for moving around to cool a smaller room or area. Even though the portable system isn’t as efficient as the central or split system air conditioner, they can be a great option for those who rent property or tend to move around often.

A portable air conditioner usually has a more fashionable appearance to go in with your home's décor. The built-in wheels make moving from room to room much easier, and they are also quite easy to manage. A portable air conditioner is ideal if you want a practical solution that you can move from room to room without spending money on.


  • Easy to move and control.
  • Great for those who rent or move often.
  • Cheaper than a larger system.


  • Inefficient
  • Noisy
  • Can Only Cool a Small Space



With the summer right around the corner, we reckon this is the right time to go out and buy an air conditioner. The best air conditioner for you can depend on a number of things, including the size of the space you wish to cool, your budget, and the features included.
