Buying Guide For The Best Window Ac In India 2021

This is a buying guide which will help you to make a perfect decision and below is all the mandatory things we have mentioned which will benefit you directly in the long term.

1. Fan’s Noise Level

Before making a purchase you should check the noise level of the window ac. Some Ac’s fan makes very loud sound even on the very low setting. This is not good while you are sleeping and you might find it irritating later on. You can manually go to the retail store and check if the desired window air conditioner has this problem or not. Otherwise, all the window air conditioners we have mentioned in this list are completely noise free and they will not bother you in your sleeping time after purchase.

2. Window Location

Window location matters a lot while you consider buying the window ac for your room. Before even consideration, you should look at the location of the window and if the window is covered or open. As window ac perform well when the window is open and where the air ventilation is good. You should check if the window is at the balcony or it is inside your shaft. If you are planning to buy for a shaft window, then you need to change the location as this will not provide the ac with a fresh air ventilation which will impact on the health of it later on. Hence, our recommendation is to install the window ac in an open window and where the air ventilation is good enough.

3. Installation

You should check if the size of the window is small compared to the room. If this is a situation then we recommend you to change the location if possible as due to the window size you have to install smaller capacity window air conditioner and that will surely not cover your large rooms or halls.

4. Easily Accessible Front Panel

Make sure the front panel is easily accessible and you can easily clean the filter out whenever possible. So, this will help you in the long term and you can maintain the air conditioner well by cleaning out the dust filter whenever needed.


  1. When my AC needs to be serviced?

    It depends on which part of the country you are living in. Like if you are living in the northern part of India, then you don't need to service for more than a year, and if you are living in southern India.
    Then, the air conditioner needs to be serviced every 6 months. The condition is the same like if you run an air conditioner for 12 months then you need to service every 6 months for better performance. Otherwise, one time is sufficient for everyone.

  2. How much power my air conditioner consumes in a day?

    This also depends on certain things like if your air conditioner has BEE ratings or not and you can check the units it consumed by comparing the old electricity bills unit with a new one. So, you can easily calculate how many units it is consuming per month.

  3. From where I should buy a new air conditioner?

    Firstly, we recommend you need to check and browse the internet which is the best air conditioner for you and select at least 2 or 3 models according to the price, features, brand,warranty and etc. Then, you should visit the nearby store and compare there if online is better or the store is giving you more discounts and then decide which one is right for you.

  4. How long does the air conditioner lasts?

    Air conditioner usually lasts a minimum 5 years or more, some air conditioners last even more than 10 years. It also depends on the air ventilation, maintenance, and how often you clean the filter.
