How does a window air conditioner work?

Window AC’s can be found all over India. They are in use for a long while. You will often find them outside the windows of office buildings. By its very name, we can understand that a window AC is installed in a window. At times, Indian’s like to cut a part out of their walls and install these machines.

Window AC’s are often called the simplest of air conditioners out there. It doesn’t need you to install different units, as the whole thing comes in one shell. The most essential thing you need to remember is that a window AC takes warm air from the room and replaces it with cold air.

Different parts of the AC play a role in making the magic. You will notice that half the part of a window AC hangs out. The reason behind it is that we can divide the appliance into an inside and an outside component. The cooling coil lies in the front, whereas the compressor lies in the back.

As the machine starts, the warm air gets sucked by the evaporator and sent to the cooling chamber. The refrigerant absorbs the heat, which cools down the once warm air. There is also a filter in the front to remove any impurities before the air reaches the compressor.

You will also notice that the air blown by the window AC is often low on humidity. This is also due to the cooling coil as the air leaves condensation, losing its moisture. The pipe that is often connected to your AC helps in getting out the collected water. Then, the cold air is passed on to your room with the help of an evaporator blower. The ‘room air cycle’ gets repeated as long as the machine is running.

At the same time, there is also something called the ‘hot air cycle.’ The fan that is on the back of a window AC helps to introduce hot air from outside. This air is used to cool down the compressor so that the refrigerant can work properly. The air absorbs the heat that the compressor has already taken from the ‘room air cycle.’ It becomes even hotter and gets expelled by the AC to the outside.

You will usually control the window AC through a remote control after switching it on. There is a thermostat that lets you change the temperature. It is often found that a window AC takes a longer time to cool down the air on a sweltering day. If you have set a higher temperature, the compressor stops after the room gets satisfactorily cold. If you want better circulation of air, then using the swing mode helps a lot.

Some air conditioners may even work as a heater. In such machines, there is often a 4-way Valve. It helps the condenser to change into an evaporator and vice versa. The mode is quite helpful in places that can get too warm or too cold, like in deserts.

Is buying a Window AC worth in India?

The market is full of choices, we will always have something new to buy. When we visit an offline or an online store, there are tonnes of options. Often it is hard for us to get ourselves set on something. As we are trying to invest in something like air conditioners, it is better to be sure about it.

We would say that it is definitely worth buying a window AC in India. There is no reason that you shouldn’t buy one of the simple appliances available to you. They are often inexpensive expenditures that last with you for a long time. If you are on a budget and have a small home, then nothing is better than getting a window AC.

Some people like to believe that window AC’s have less effectiveness, but that isn’t true. They are great at cooling down small places in just a couple of minutes. You should definitely make sure to buy the right capacity size according to the area of your room.

If you worry about energy consumption, then check out the energy efficiency ratings of an AC. Also, make sure to get an inverter air conditioner if there are sudden power cuts at your place. Most good brands make multiple window AC models with the best features.

We will always recommend you to personalize your shopping experience. Focus on your needs for a particular AC and shop around it. Do not get coerced into buying an over-budget window AC that you may not need.

Best brands for Window Air Conditioners

10 things to check before buying a window aC

What type of window AC are you trying to buy?

Have you already decided on the qualities and features that stand out for you?

Do you have a specific budget?

These are some of the questions that you will need to ask yourself before you get the window AC. Rather than going for a random model, it is essential to decide the features that should stand out. We have recognized ten points to think about before getting an AC. So, let us know a bit more about them. Following them will help you to find the best window ac in India.

1. Capacity According to the Size of the Room (Tonnage)

When you start searching for ACs, you will notice that most of them come with a specification of ‘ton.’ Usually, window ACs range from 1 ton to 3 ton, but it may vary. The measure of ton helps you to understand which room area it will cover. So, a window AC with a lower ton capacity is inefficient for a bigger room. It will also require eating up much more energy. If you have a place that is too big, we will recommend you to go for multiple ACs. 1.5 ton is the most common capacity, and it is suitable for a room with an area of up to 200 sq. ft.

TonnageRoom SizePower (BTU/hr)
0.8 TonUp to 100 sq. ft.9600
1.0 TonUp to 150 sq. ft.12,000
1.5 TonUp to 200 sq. ft.18,000
2 TonUp to 250 sq. ft.24,000
3 TonUp to 400 sq. ft.36,000

2. Energy Efficiency

In India, the energy efficiency of an appliance is generally counted through stars. You can often see labels on top of home appliances denoting the stars. We will only recommend you to buy an AC that has 3 to 5 Stars. These will be the best machines that consume the lowest energy. Do not buy a window AC that doesn’t have the EE ratings on them as they may not be cost-effective. Compare the units consumed by different window air conditioners before purchasing.

You should know about the BTU or British thermal unit measurement of an AC. It isn’t widely used in India, but you may come by a model with it. So, 1 Ton equals to 12000 BTU/hr. So, you can consult the above chart to find the BTU vs Ton calculations. A window AC with a higher BTU amount will have more energy consumption than one with a lower value.

3. Different Modes and Settings

Will you be happy if your AC runs only in one mode? Definitely not! The window air conditioners should have a certain level of customization. It includes things like sleep mode or the energy-saving mode. So, you should check the different settings that come with a particular model. Good models will have several of them, but do not get stuck to it. Your window AC should have a good temperature range, along with some basic settings. We find air swing very important, so make sure that it is present in your AC. Also, keep an eye on the different speed settings. If you live in an area that gets too cold, then look for a window AC with heating capacity.

4. Coil Material

Brands usually use steel, copper or aluminum in their coils. Copper is the best that you can go for as they last the longest. Some ACs with copper coils have been serving people for more than 15 years. So, pay attention to the material along with added protections that it might contain. As coils form dew on them, it is always essential to have water protection. You should always get familiar with the insides of a window AC as it is going to be a significant investment.

5. Air Filtration and Humidity

There was a time when people didn’t care about the filter used in an AC. But, that is far from the truth when it comes to the current time. With the number of air pollutants present in our rooms, a filter is a must. Many window ACs also have multiple filters to make the air quality even better. So, make sure the window AC has a good air purification system.

On top of that, we would also tell you to have a look if it has a dehumidifier or not. Often the cold air gets too dry and uncomfortable. It is essential for areas that are already dry and unbearable in summers. If you are in a humid and sweaty climate, look for the dry mode for the best results.

6. Inverter Technology

As we are looking for a window AC in India, it is best to go for appliances with inverter technology. If you live at a place where power outages or fluctuations are common, they help a lot. In-built inverters take care of the compressor and the motor of the AC. It also makes sure that it isn’t consuming too much energy. But, these models do cost more, so keep that in mind.

7. Installation and Maintenance

One of the crucial things about a window AC is that you need to install it. So, make sure that the company provides a smooth installation process. You may need to give some time for the procedure. The installation should be done without a gap between the appliance and the window/wall. You should also check with the brand for the appliance’s yearly maintenance. In a hot and humid country like India, ACs need a check-up every year. Most companies come up with a hassle-free maintenance package with excellent discounts. So, do not forget to ask about it.

8. Noise

Currently, most companies make us believe that their appliances do not produce noise. But that isn’t true in most cases. If you are looking forward to installing a window AC in your bedroom, check its noise level. Most of them will have a noise range of 40 to 60 decibels. So, try to go for the lower range if you have a pet or baby in your house. Make sure to buy one with a sleep mode for better results.

9. Warranty

We cannot tell you enough about the benefits of the warranty. It may range from 1 to 5 years, depending on the brand. A warranty will help you if the AC gets into trouble. Many brands also provide an extended warranty on the compressor. So, keep an eye for the best warranty offers.

10. Budget

As we have said before, window ACs are economical. But that doesn’t ensure it is cheap. You should go for the best deal rather than just looking at its price tag. To ensure that everything works out fine, get yourself into a budget. Look for Window ACs that fall in that particular bracket. Always tally between different products to see the benefits of one over the other. We are sure that your calculations will help you to land a deal.
