Things to Consider Before Buying The Best Window AC in India

Choosing the best window Ac in India can be very confusing because there are various models available in the market. Each model has its unique and elegant features, making it very difficult to choose the best window Ac for your home or office. Your purchasing will be very easy, if you create a checklist of what you need in Window AC. Every AC must have some standard features. First of all, we suggest looking for ideas that should be mandatory and then relate them to your needs. If the product meets your needs and basic features, then go ahead and buy it. Here, we have given some of the essential factors to look for while purchasing a window AC. 

Room Size

The room size is the first thing you should consider in AC. The window ACs have their own cooling capacity, which is related to the room size. If you want to install a window AC to your 50 to 100 sq ft room, then a 1-ton window AC is the best choice for you. Usually, 1 ton window ACs are perfect for children’s rooms, study rooms, guest rooms, or other small and medium-sized rooms. 

If your room size is 120 to 200 sq ft, then you can install a 1.5-ton window AC. The 1-ton AC cannot cool the whole room, but 1.5-ton AC accurately cools the entire room and is suitable for medium to large-sized rooms. When your space is above 200 sq ft, then you can go for a 2-ton window AC.

Digital Controls

The next thing you must consider is the digital control feature. The window AC with a digital control feature easily sets the cooling temperature, timer and sleep mode. Cheaper models begin with a simple knob system. However, an AC with a wide range of digital controls can be a little costly. So, before buying, see your budget and then move for it. 

Power Consumption

In India, the summer season is very hot. You can not imagine a day or night without AC. So, your AC will work for at least 5-7 hours a day. With this usage, the electricity bill increases fastly. Nowadays, most window ACs come with energy-saving technology that helps to reduce more power consumption. So choose a window AC with energy-saving technology. 

All the window ACs are working on various power wattages, and they consume less or a high amount of power compared to others. Based on power consumption, they receive an energy rating from BEE (Bureau Energy Efficiency). If the energy rating is higher, then it uses only less power. For example, a 5-star rated AC will use less power.

Power Requirements

A conventional window AC typically operates at a voltage of 230V. So, before you buy, make sure that your home has the correct prerequisites. Three fundamental modules are more important for installing the air conditioner to your home, they are proper wiring, continuous and efficient power supply, and appropriate sockets. If your home does not have these three fundamental conditions, then the air conditioner will not function properly. 

Modes of Operation

Typically, window ACs come with various operation modes that are used for multiple purposes. For example, the humidifier mode helps to decrease indoor humidity and maintains your room fresh and hygienic. This mode can also remove bad odor. The window AC models also have a sleep mode that allows the product to control heat automatically. By doing so, it can reduce excessive power consumption. Also, you will not wake up at night to turn off the AC.

The dry mode helps to reduce humidity.  It will significantly reduce the development of algae and unhealthy odors.  Most people like dry mode in window AC because it effectively reduces humidity during the monsoon season. The cool mode increases the cooling capacity of your window AC. It can be increased or decreased by changing the temperature setting and fan speed. Ideally, a temperature of 25⁰C is a convenient option for Indian environment.

The quick cool mode in window AC can quickly reduce the room temperature. If you live in a hot region like Mumbai, it will be an excellent choice for you. However, this special mode is not energy-saving. If the air conditioner is active for a long time, it will also affect the coil. 

The 6th Sense Cooling mode is one of the unique features of window AC. This feature allows the AC to understand your room temperature and adjust its cooling accordingly. This mode is less energy-consuming and very efficient and can also maintain your electricity bill under control. But, only very few models are available with this feature in the market. 


When discussing India’s best AC, the first thing that comes to mind is the uncomplicated installation process. The installation method varies from one model to another, but the window air conditioner provides you a straightforward function. You will receive all the guidance in the manual. So, you should follow the directions step-by-step. 

Noise Production

Another factor to consider when purchasing the Best Window AC in India is its noise production. Especially in India, Most people use air conditioners in their homes, and they use it before going to sleep. So, if it makes a lot of noise, it is hard for you to sleep better.  So you can purchase a model with a 50-65 dB noise level and shouldn’t exceed this level. Otherwise, you may have difficulty sleeping.

Additional Features

The coil of the window AC should be designed with copper material because copper provides superior and faster cooling within a short period of time. It is simple to maintain and works for an extended period. Nowadays, most of the window ACs come with an anti-bacterial filter and anti-fungal filter, which helps filter out the bacteria, fungus, and other harmful microorganisms from your room.

Final Words
