Window AC Buying Guide

This machine (AC) has a reputation of serving us for a long time. Usually, one does not change or replace air conditioners at least for a period of 6 to 8 years. This makes it important to choose the most energy efficient machine for our homes. Now, you have a lot of air conditioners in the market.

You have different types of machines like the window AC units, the split AC units, the inverter air conditioners, and the portable air conditioners. We are not referring to the centrally air-conditioned units as all because they do not come under the category of individual air conditioners. Also, have a look at Split AC vs Window AC.

The best AC is one that offers you the highest efficiency while consuming the least amount of electricity. At the same time, it should be affordable as well. Thus, you see that a lot of factors come into consideration when you sit down to buy the best AC for your house.

In addition to the above-mentioned factors, there are certain other factors that should influence your choice of air conditioners. Let us look into these factors. Some of them are not under your control whereas some are.

  • The city where you live
  • The area of the room where you wish to install the AC
  • Daily usage of the AC unit
  • Number of months in a year you will be using the AC

Let us consider the factors one by one.

City of residence

The outdoor temperature is an important factor. Higher the temperature, the more will be the load on the AC. Summers in Delhi can be hotter than that in Mumbai. At the same time, summers in Mumbai can be longer than that in Delhi. This is one factor that is not under your control. Hence, you cannot do much about this. Let us now consider the factors that you can control.

Size of the room

When we speak about the size of the rooms, we refer to the volume and not the area of the room. Normally, rooms in India are around 10 feet in height. If we discount this factor as a common one, you are left with the area. Greater the area, the more powerful will be your AC. Automatically, this affects your budget. Choosing the AC with the right tonnage / capacity is important for optimum performance.

If you have an AC with a lower capacity, you are putting more pressure on the AC to cool the rooms. This affects the performance and increases the electricity consumption as well. At the same time, installing an AC with a higher capacity can also result in overcooling of the room. Choosing the right mix is important.

Based on the area of the room, this table will give you a decent idea of capacity of the AC to go for.

  • Up to 80 sq ft. – 0.75 ton AC would suffice
  • 80 to 120 sq ft. – Opt for a 1 ton AC
  • 120 to 190 sq ft. – This is the most common scenario in India. Go for a 1.5 ton AC
  • 190 to 300 sq ft. – These are larger rooms, hence you need a 2 ton AC
  • Over 300 sq ft. – The best option is to consult an AC technician. Installing 2 AC units in these rooms can be beneficial because, you can localize the cooling in a particular area if necessary.

There are other factors as well, such as presence of electronic instruments in the room, the cupboards, and wardrobes, etc. However, the table mentioned above should suffice.

Daily usage and number of months you will use the AC

You need to factor in this aspect to calculate the amount of electricity you would consume. This affects the ROI of the air conditioner.

BEE Star Rating

The Bureau of Energy Efficiency has stipulated ratings for each type of AC equipment. It accounts for various factors, the most important of which is the consumption of electricity. This is the efficiency of the AC unit. Based on this efficiency, they have stipulated ratings ranging from 1 star to 5 stars.

Naturally, the 5-star rated AC units are the most efficient. They are the most highly priced as well. However, the costs even out in the long run because 5-star AC units save you a lot in energy consumption costs.

Hence, it is always better to choose a window AC with 5-star rating. They cost you more initially, but save you a lot of money over the entire life of the AC equipment.

When you go shopping for an AC, you should be aware of certain aspects or features of window AC units. Let us look into some of these simple but essential aspects. Also, Read Understand AC jargon like ISEER, EER, BEE Star Ratings

Aluminium coil vs Copper coil

You have different types of coils in an AC unit. There are condenser coils, evaporator coils, etc. The materials used for manufacturing these coils are important. Usually, you find aluminium or copper are the principal materials. Which of these two is preferable?

Efficiency wise, you can see that copper has a higher heat transfer rate. It is also less corrosive than aluminium while having higher coil strength as well. Aluminium coils are economical as they are cheaper. One should have an idea about these simple aspects. Checkout our in-depth guide about Copper Coil vs Aluminium coil in AC.

Features you normally encounter in an AC

Marketing is a very important aspect. You find different manufacturers highlight different features of their products. It can be very easy for you to get influenced by their claims. Of course, they are not wrong in any way. Does it do any harm to you to know how to read between the lines? On the contrary, you become more informed and are thus able to make a better choice.

Let us look at some features in an AC unit.

Anti-bacteria filterDust filterDehumidifierAuto Clean functionAuto-detect

The AC has a dual responsibility. It provides cool air and brings down the temperature inside the room. In addition, they have a responsibility to provide pure air for breathing. Hence, you have modern-day AC units having anti-bacteria filters. These filters can trap dust mites, pollen, bacteria, and other allergens thereby providing fresh air. At the same time, it protects the internal parts of the AC and increases its life.

These filters have the job of filtering out the dust from the air. In fact, one should clean these filters once a month. This will give you an idea as to the amount of dust we inhale every day. The accumulation of dust on these filters makes the AC work harder thereby reducing its life. This explains why cleaning dust filters should be our prime concern.

Air contains a lot of moisture. This explains why we feel stuffy and sweaty in the summers. The AC has a dehumidifying function that removes the excess humidity from the room. The removal of the humidity from the room makes it comfortable and reduces the chances of bacterial infections as well.

This functionality ensures that there is no accumulation of mould or bacteria on the internal parts of the AC. This improves the cooling thereby increasing the efficiency and enhancing the life of the AC unit.

With the advancing technology, you have this ‘Auto Detect’ facility in the modern-day AC units. This function enables the AC to detect the number of people in the room and adjust the temperature accordingly. Now, that is what you call a smart AC.

 

Frequently Asked Questions

1Which AC is better? Split AC or Window AC

Honestly speaking, the split AC is more efficient than the window AC of similar tonnage. The BEE Star ratings show that the window AC units are always 1 point below the split AC ratings for similar tonnage. However, window AC units are less expensive than the split AC units. An important point to note is that the split AC units are economical in the long run as they save you a lot of electricity.

2Is it better to go for a higher tonnage of AC?

A lot depends on the size of your room. You can check up the size of your room with the table provided in this article and decide accordingly. An AC unit of higher tonnage can cause overcooling of the room. In addition, it can consume more electricity as well.

3I have a small budget. Should I go for a window AC or split AC?

Let us be very honest. A split AC is more efficient than a window AC of equal tonnage. Considering the moving trends, manufacturers are concentrating more on the split AC units. Remember, you normally get 5-star window AC in 1.5 ton alone. Research shows that a 4-star split AC is equivalent to a 5-star window AC. Therefore, it is advisable to go for a split AC. However, if your budget is really tight, go for a 5-star window AC of 1.5 tons.

4Does my AC require a stabilizer?

It depends on the input voltage fluctuations in the place you reside. If there are huge voltage fluctuations, it is always better to have a stabilizer to absorb the sudden surges. It can protect your AC from unnecessary damage. The advantage is that you will be able to use the AC even during low input voltage as well. These stabilizers maintain the output voltage at the desirable levels.

5How much electricity does an AC consume?

A lot of factors go into the calculation of electricity consumption. They range from the tonnage of the AC to the temperature setting. The speed of the compressor is also an important factor. The fixed speed compressors consume more electricity than the variable speed compressors. The thumb rule is that a 1450 Watt AC will consume 1.16 units per hour if it is a fixed speed AC. In case of the inverter AC units, the consumption will be around 0.928 units per hour. These are approximate values.
