Almost everyone today owns an air conditioner. There are many types available such as 1 ton Ac or Split AcBut the important aspect here is to get a product that is viable enough for you economically, and it promises durability with good performance as well.

Picking the perfect product, be it anything, can also prove to be a tricky job. You must have several questions based on exactly what product to get, something that will be brilliant for your interiors.

Whether the AC will fit into your window space correctly? Or if it will blend in well with your surroundings and ambiance of the room? Or if it will provide the perfect amount of cooling at the perfect price?

Well, worry not because we have come up with the perfect guide to help you make an informed decision. If you want a perfect escape out of this burning heat, and want a good AC to solve that problem, well then all you need to do is follow our detailed guide, and we promise you that it will help you gain more perspective on what you can buy, on what you must buy and how you can buy it.

We have also mentioned working of AC, the difference between Window ac and Split ac and FAQ’s. Check out Our Top Window Acs that will help you make the right decision.

Working of window AC

The Window AC comes with a blower, compressor, and a cooling coil with the help of which the air is cooled. Once the AC is switched on, the compressor starts working, and the blower begins to operate to suck in the hot air that is full of dust particles. The air is then passed through the dust and anti-bacterial filters so that the air released is free of these contaminants.

The hot air is then passed to the cooling or evaporating coil, which in turn drops the temperature of the air by absorbing the heat from it. The moisture is evaporated from the air to adjust the level of humidity.

Once the process of lowering the temperature and humidity of air is complete, the blower sucks in the air and releases it in a high velocity through a metal duct, out through the front panel of the AC. Thus, the air we obtain in the room is fresh, clean, chilled.

However, it doesn’t remain the same as the moisture level in the room is higher. As a result, the blower again sucks in the air to repeat the entire process.

It is also important to understand the hot air cycle of the window AC to know more about its working.

The cycle mainly focuses on the cooling of the condenser using the external or atmospheric air. The condenser is the part of the AC that is present outside the room. The fans of the condenser suck in the high-temperature atmospheric air to cool it down.

The condenser comes with a refrigerant; however, it is hot. So when the air is sucked in and passed through the condenser, the temperature of that air further rises.

Once the air is cooled, the refrigerant passes through the expansion valve and then the cooling coil. Now the hot air gets blended with the atmosphere while the fresh atmospheric air is sucked in and passed through the condenser to continue the cycle.

Difference between window ac and split ac

A window AC requires a window for installation and comes with a single indoor unit while a split ac requires no window, and it comes with two units, i.e., an indoor and outdoor unit. Both these Air Conditioners are equally energy efficient. However, Split air conditioners have several 5-star energy rated models.

Moreover, the outlook and design of a split ac are more aesthetic than compared to a window AC, plus they make less noise. However, they require more space to install while window ac require very less space and are far easier to install. Window AC is more of an affordable option than split ac.

Buyers guide

Dust filter

The model you purchase should have an in-built anti-dust filter so that the air you breathe is fresh and clean. This filter manages to remove the dust, allergens, odors, and other harmful particles from the air conditioner. So, the air you breathe is filtered.

Anti-bacterial filter

This is another important filter that filters the indoor air so that we get to breathe in air that is free from micro-organisms, dust, and other impurities. The anti-bacterial filter traps the micro-organisms, bacteria, viruses, and dust particles through microscopic pores and fibers so that the air is clean and fresh. This also enhances the life span of your AC and provides relief from respiratory issues.


The Window AC should come with a Dry mode. This mode is highly beneficial as it dehumidifies the air inside the room, especially during the monsoons, when the humidity of the air is higher. Thus, it regulates the humidity accordingly to ensure comfort.

Auto clean

The auto-clean function prevents the growth of micro-organisms and eliminates the moisture from the interior. Thus, the evaporated moisture from the unit ensures that the air you breathe is more clean and safe. This feature is a must-have, especially for high moisture levels in the air. It also manages to prevent the rusting of the evaporating coil.


Go for a brand that ensures quick installation after the purchase of the model. The brand will contact you after purchase, or you will have to contact them to provide the model number and other details.

Smart technology

The model should come with smart technology so that it offers you features like auto-restart and sleep mode. The auto-restart function ensures convenience as you will not have to reset the temperature settings after a power cut manually. It will automatically adjust itself to the temperature it was set at.

The sleep mode, on the other hand, ensures comfort while sleeping. It increases the temperature by one degree Celsius per hour for the first two hours. Then it maintains a steady temperature for the next five hours.

Energy Efficiency

The Window AC should come with at least a 3-star rating from BEE so that it saves 15 % energy. Energy-saving features like eco-mode are also important as they save energy and expenses on your electricity bills.


Choose the cooling capacity based on the size of your room you wish to cool. A 1 ton AC is suitable for a small room size while a 1.5-ton capacity is ideal for medium size rooms if you have a large room go for a 2 ton AC.


The warranty of the product is significant. One must make sure that the product comes with a good enough, valid warranty. The warranty helps in recognizing the durability and longevity of the product, which is very vital.


Whatever product one chooses to purchase should promise to be worthy of the money that one is paying for it. You must make sure that you get a product that has all the settings and characteristics which make an AC desirable enough for the pricing it asks for. If that is not the case, then it is considered a wastage of money.

Noise Level

One must check the noise level of the product before making a purchase. This tells us how much noise the product makes while being operational. You do not want to buy an AC, which is making constant noise while working.


This is the most vital feature of the AC. We buy an Air conditioner to make sure our indoors at least have a fresh and pleasant temperature. This can be achieved only by making sure that the device has a great cooling system and that it does so quickly and efficiently.
