What are window air conditioners?

Window air conditioners are the most traditional way of cooling your rooms. As they are bulky and heavy, they can be fit inside the window’s pane and can be operated from there. Depending upon the BTU’s, age of the unit and the room in which it is installed, window air conditioners can call a small room in a very short period.

The working of the window air conditioners can be explained by considering two cycles of the air; room air cycle and hot air cycle. The air moving inside the room and those which are located at the front side of the conditioner is considered to be the room air. As soon as we switch on our conditioners, the fan starts to blow.

After sometimes, the compressor starts, and the evaporating coil or the cooling gets cooled as soon as the compressor is started. The blower behind the cooling coil sucks the high room air temperature. On its way, the dust and dirt particles are also carried along through the filters proving that the conditioners can also clean up the dirty air around you.

The air which is sucked along is at high temperature. When this air comes over the cooling coil, it absorbs the heat of the room air and makes it chilled. Due to the reduction of the temperature from the air, some dew is formed over the cooling coil because of the fact that the temperature of the cooling coil is less than that of the dew temperature of the room air.

This low-temperature air is then sucked and blown at very high pressure from the duct, which is provided on the air conditioners from the front panel or the grill giving a cooling effect inside the room.

Best air conditioners are those who produce only the noise of the running fans and no other noise, which causes disturbance inside the room.

Window location

Air conditioners do a better job by blowing the air in one direction. If you need to cool the entire room uniformly, you need to know the exact location where to fit the conditioners. You need air more towards the right or the left. Nowadays, most of the air conditioners come along fans which swivel on both sides, proving to give out better results.

Install it correctly

A window air conditioner gives out the best result only when it is installed and positioned in the best way. If you have placed the AC unleavened, the drainage would be affected. Look around appliances around the units that generate heat from it and always install them away from the ACs.

Check Filter Location

Make sure you position your filters in the best place because you need to frequently access it to clean it after using it for sometimes. Filter cleaning is a very important part while using a window air conditioner.

Consider Intelligent cooling

Inside your budget

The most important factor while buying a product is its price. Set a budget inside your head and buy something which fits inside your budget.

Electrical Requirements

The window ACs are commonly used in every domestic and small commercial place. Before buying the window AC, make sure the electric system supports the ACs and meet the need of the unit’s electrical requirement like voltage, amps, and watts.

The window ACs are a bit more powerful than other household appliances, so you should check if the model you’re planning to buy needs special electrical wiring.


Window air conditioners need timely maintenance as they can be exposed to outside dirt and other rubbish, which can gather inside or on the back. The dust on the air filter will eventually reduce the effectiveness of your air conditioner if left untreated.


Window AC unit is designed to fit inside standard double-hung windows, but you can install it inside a wall space created especially to fit in the AC. Dimensions of the window should be measured properly, especially the width, and then compare it with the AC’s specifications.

But if the window is bigger than the AC, make sure to inform the installation service providers who might come with an installation kit. Some window air conditioners feature a removable frame to have easy access to maintenance.

Energy Efficiency

Search for energy star rating or EER number. The energy star implies that the conditioners will use lesser power than the other non-rated ACs. Go for units with three or more stars.
