Air Cooler or Air Conditioner: Which is the Best?

Air Cooler or Air Conditioner

If you are looking for a way to cool your home or office, you might be wondering whether to choose an air cooler or an air conditioner. Both devices can lower the temperature and make you more comfortable, but they have different advantages and disadvantages. In this article, we will compare the air cooler and the air conditioner based on their working principle, initial cost, energy consumption, installation, and maintenance. By the end of this article, you will have a better idea of which one is more suitable for your needs and budget.

Working Principle

An air cooler works by evaporating water to cool the air. It has a fan that draws in hot air and passes it through wet pads that absorb the heat and release cool air. An air cooler also adds moisture to the air, which can be beneficial in dry climates.

An air conditioner works by using a refrigerant gas to transfer heat from the indoor air to the outdoor air. It has a compressor that pressurizes the gas and makes it hot, and an evaporator that cools the gas and absorbs heat from the indoor air. An air conditioner also removes moisture from the air, which can be helpful in humid climates.


An air cooler is generally cheaper than an air conditioner. You can find an air cooler for as low as $100, while an air conditioner can cost you several hundred or even thousand dollars depending on the size and model. An air cooler is also more portable and does not require any installation.

An air conditioner is more expensive than an air cooler because it has more complex components and requires more materials. An air conditioner also needs to be installed by a professional, which adds to the cost. An air conditioner is usually fixed to a wall or a window and cannot be moved easily.

Energy Consumption

An air cooler consumes less energy than an air conditioner because it only uses electricity to power the fan and the pump. An air cooler can use up to 80% less electricity than an air conditioner, which means lower utility bills and less environmental impact.

An air conditioner consumes more energy than an air cooler because it uses electricity to power the compressor, the fan, and the evaporator. An air conditioner can use up to 10 times more electricity than an air cooler, which means higher utility bills and more greenhouse gas emissions.


An air cooler does not need any installation. You just need to plug it in, fill it with water, and turn it on. You can also move it from one room to another without any hassle.

An air conditioner needs professional installation. You need to drill holes in the wall or window, connect pipes and wires, and mount the indoor and outdoor units. You also need to make sure that there is enough space and ventilation for the device.


An air cooler requires regular maintenance. You need to clean the pads, change the water, and check for leaks and mold. You also need to store it properly during winter to prevent damage from freezing.

An air conditioner requires less maintenance than an air cooler. You only need to clean or replace the filters, check for refrigerant leaks, and service the unit once a year. You do not need to store it during winter because it can operate in both heating and cooling modes.



An air cooler and an air conditioner are both effective ways to cool your space, but they have different pros and cons. An air cooler is cheaper, more energy-efficient, more portable, and more natural, but it is less effective in humid climates, requires more maintenance, and increases humidity. An air conditioner is more expensive, more energy-consuming, more fixed, and more artificial, but it is more effective in all climates, requires less maintenance, and reduces humidity.

The best choice for you depends on your personal preference, budget, climate, and space. If you live in a dry climate, have a small budget, and value portability and eco-friendliness, you might prefer an air cooler. If you live in a humid climate, have a large budget, and value performance and convenience, you might prefer an air conditioner.
