Buying Guide – Best Window AC in India
Window ACs used to be very popular before split ACs became commonplace. However window ACs have their own utility and they are still used by many households in India. One of the biggest advantages of Window ACs is that it comes at a decent price point. This affordability makes it a popular air conditioning unit.
The best window AC is one that gives the highest efficiency while consuming less electricity apart from affordability. Let us look at the factors that should be considered before buying window ACs.
- The size of the room where you wish to install the AC
- Star Rating
- Usage of the AC
Size of The Room
This is the number one factor in deciding the tonnage of the window AC that you will have to buy. Larger room will require higher capacity AC. Rule of thumb is that any room with more area than 180 – 200 square feet will require more than 1 ton AC.
If you buy a lesser capacity AC for larger room, then it will have to work harder, which will result in higher energy consumption. At the same time, higher capacity AC will also result in more higher investment.
Window ACs come in 0.75 ton to 2 ton capacity. This table will give you an idea about the ideal capacity of window AC.
|Room Size||AC Capacity|
|120 sq. ft.||0.8 ton|
|120 to 180 sq. ft.||1.0 ton|
|180 to 270 sq. ft.||1.5 ton|
|270 to 400 sq. ft.||2.0 ton|
BEE Energy Star Rating
All window ACs come with energy star rating as mandated by BEE. 5 star ACs are most energy efficient, while 1 star ACs are least energy efficient. Over the years, rating of window ACs have become more stringent.
We have calculated savings on electricity bill as per star rating of Window AC.
This table shows the amount of money you can save in a 1.5 Ton Window AC at different star ratings.
|Star Rating||Units Consumed Per Day||Power Cost Per Month||Cost Saving Per Year|
|5||12.6||Rs 2420||Rs 3873|
|4||13.4||Rs 2577||Rs 3092|
|3||14.3||Rs 2754||Rs 2204|
|2||15.4||Rs 2958||Rs 1184|
*Assuming 8 hours operation per day for five months in year and Rs 6.4 / unit is cost of electricity
As you can see a 5 star window AC is 32% more energy efficient as compared to 1 star AC. Thus, it can save Rs 3873 per year over a 1 star Window AC.
Usage of AC
If you are planning to use AC less and for lesser number of months, then 5-star AC may not be the best fit. You can buy a 3-star AC in that case. However, a 5-star AC is best suited for heavier use so that you will be able to recover the higher cost will this AC in short period of time.
Benefits Of Buying A Window AC
Finding the difference between split AC and window AC is essential before purchasing an AC. Here we have outlined some of the advantages of window AC.
As discussed, affordability is the best advantage of Window ACs. A Window AC’s price can start from as low as Rs 15,000. This is quite low as compared to other types of ACs in the market. However, higher priced window ACs are also there in the market. Some window ACs can also cost as much as Rs 40,000 as well.
Ideal for Small Room
Window ACs are best for smaller rooms as they offer optimum cooling at affordable rates. Also, they do not take any area inside the rooms as the cooling unit is placed outside the window. This is decent advantage if you live in a house with smaller rooms.
Easy Installation and movement
Window ACs are quite easy to install as these ACs do not require drilling holes in the wall or installing ducts. This makes window ACs best suited for users who are on the move or who are living in rented apartments.
The process of installation of window AC is quite straight-forward and only slightly different for different window ACs. You will get all the instructions in the manual that comes with the AC unit and it can be installed without help of an expert.
Features to Expect in A Window AC
Apart from cooling air, ACs also perform air purification. Most window ACs come with filters for purifying air. These filters filter out dust from air. These filters should be cleaned once every month.
Usually, PM 2.5 filters are better than other types of filters in Window ACs. Thus, this type of filter should always be preferred.
Anti-bacterial filter can block growth of bacteria such as e. coli, staphylococcus etc. Different brands have different technology for filtering bacteria, for example, Voltas has Acaro Anti-bacterium filter, Carrier has Biofilter and Blue Star has also has ACs with anti-bacterial filters. Many anti-bacterial filters work by charging the agents negatively and then attract the bacteria and other agents by producing opposite, positive charge.
HD Filters or high density filters are more advanced form of dust filters and can remove bacteria, pollen, dust mites and other allergens from the air. Brands such as Samsung and LG use these filters.
Almost all window ACs come with a dehumidifier. This feature removes moisture in the air. If you are feeling uncomfortable due to higher humidity, then you can use the feature to decrease the moisture. It is especially useful during rainy season.
This can also be useful to reduce the effect of covid19 virus as well.
Auto Clean function
This feature removes the moisture from inside the AC unit. This helps prevent growth of microorganisms inside the AC unit. It works by blowing air inside the AC unit once the AC is switched off. Thus, evaporating any moisture present inside the AC. However, it should not be confused with filter cleaning which has to be done manually on a regular basis as there is no automatic filter cleaning feature in window ACs as of now.
This feature detects the number of people in the room and adjust the temperature of the AC accordingly.
