ruminesia – When choosing between cooling a room and buying an AC, you might wonder, “Is It Better to Buy an AC or an Air Cooler?” Both have advantages and disadvantages, depending on your needs and environmental conditions.
An AC generally offers more effective cooling, especially in larger rooms, but at a higher energy cost. On the other hand, an air cooler is an energy-efficient and more portable alternative, suitable for smaller spaces.
This article will discuss the main differences between ACs and air coolers, factors to consider when choosing, and recommendations based on personal experience.
What Are AC and Air Coolers?
An AC, or air conditioner, is a cooling device that uses refrigerant gas. This device effectively maintains a cool and comfortable room temperature, especially in hot weather.
Meanwhile, an air cooler, often referred to as an evaporative cooler, operates differently. It uses the principle of water evaporation to cool the air. Hot air from outside is drawn in and passed through wet pads.
Air coolers are more suitable for areas with low humidity, as they lower temperatures through natural evaporation.
Fundamental Differences Between AC and Air Coolers
| Aspect | AC (Air Conditioner) | Air Cooler |
|---|---|---|
| Cooling Method | Uses refrigerant | Water evaporation |
| Minimum Temperature | Up to 20°C | Up to 5°C |
| Energy Consumption | 400 – 1,000 watts | 50 – 250 watts |
| Portability | Not portable | Portable |
| Humidity | Decreases humidity | Increases humidity |
| Cost | More expensive | Cheaper |
| Maintenance | Complex | Simple |
1. Cooling Method
An air conditioner cools the air by using refrigerants. It works by drawing warm air from inside your room, passing it through coils filled with refrigerant, and then circulating the cooled air back into the space. This method can significantly lower the temperature, often around 20 degrees Celsius.
In contrast, an air cooler operates on the principle of water evaporation. It pulls in hot air and passes it through wet pads, where the water evaporates and absorbs heat from the air. This process results in cooler air, but the temperature drop is typically only about 5 degrees
2. Energy Consumption
Air conditioners consume considerable power, usually 400 to 1,000 watts, depending on the model and its cooling capacity. Air coolers are much more energy-efficient, consuming significantly less power, typically between 50 to 250 watts. This makes them a more economical choice for cooling.
3. Portability
Most air conditioners require permanent installation, which makes them less portable. While portable AC units are available, they still need proper ventilation to function effectively.
Air coolers are designed for portability. You can easily move them from one room to another without any special installation requirements, making them a convenient option for cooling different spaces.
4. Humidity and Air Quality
Air conditioners help reduce humidity levels in a room, making them ideal for humid climates. They keep the air dry and comfortable, benefiting your overall comfort.
On the other hand, air coolers increase humidity due to the evaporation process. This can be advantageous in dry climates but may not be suitable for areas with high humidity, as it can make the air feel muggy.
5. Cost and Maintenance
Air conditioners generally have a higher initial purchase price and ongoing maintenance costs. They require more complex maintenance routines to ensure optimal performance.
Air coolers are typically more affordable to buy and maintain. Their simpler components mean that they usually require less upkeep, making them a budget-friendly option for cooling your space.

When it comes to cooling your space, choosing between an air conditioner (AC) and an air cooler can significantly impact your comfort, energy bills, and overall satisfaction. Here are some key factors to consider to help you make the best decision for your needs:
1. Room Size
If you have a large room or an open-concept space that requires substantial cooling, an air conditioner is typically the better choice. AC units are designed to cool larger areas effectively, and a higher-capacity model can maintain a comfortable temperature even on the hottest days.
Air coolers are more efficient for small to medium-sized rooms. They work best in spaces needing localized cooling, such as a bedroom, home office, or small living area.
Since air coolers rely on the evaporation of water to cool the air, they are ideal for smaller areas where the cooling effect can be felt more immediately.
2. Energy Consumption
Air conditioners generally consume more electricity, which can lead to higher energy bills, especially during peak summer months. Standard AC units can use anywhere from 400 to 1,000 watts, depending on their size and efficiency.
In contrast, air coolers are much more energy-efficient, typically consuming between 50 to 250 watts. This lower power consumption helps you save on electricity bills and makes air coolers a more environmentally friendly option.
3. Portability
One of the standout features of air coolers is their portability. Most models are lightweight and come with wheels, allowing you to move them from one room to another easily.
Most air conditioners are designed for permanent installation, which can limit their mobility. While portable AC units are available, they require proper ventilation, such as a window or exhaust hose, to function effectively.
4. Environmental Humidity
Air conditioners are excellent at reducing indoor humidity levels, making them suitable for humid climates. Removing moisture from the air helps create a dry and comfortable environment, which can be particularly beneficial in areas with high humidity.
Conversely, air coolers increase humidity levels due to the evaporation process. This can be advantageous in dry climates, where the added moisture can improve air quality and comfort.
However, in humid areas, using an air cooler can lead to excessive moisture in the air, potentially resulting in discomfort and the risk of mould growth.
5. Initial Cost and Maintenance
Air conditioners typically require a higher initial investment, which can significantly affect your decision-making process. In addition to the purchase price, AC units often come with higher maintenance costs due to their complex components and the need for regular servicing.
This includes cleaning filters, checking refrigerant levels, and ensuring the system operates efficiently. However, if you need consistent and powerful cooling, the investment may be worth it in the long run.
Air coolers are generally more affordable to purchase and maintain. Their simpler design means that they usually require less upkeep, which can save you money over time.
Maintenance tasks are often limited to cleaning the water tank and pads, making them easier to manage. If you’re looking for a budget-friendly cooling solution that still provides effective relief from heat, an air cooler is a practical option.
When should you choose an AC or an Air Cooler?
Choosing between an AC and an air cooler can depend on several important factors. Each device has its pros and cons, so it’s crucial to tailor your choice to your needs and living conditions.
When to Choose an AC
Use an AC if:
- You have a large room and need maximum cooling.

Is It Better to Buy an AC or an Air Cooler?
I have two cooling devices at home: an AC of the Sharp brand (model AH-A5UCY) and an air cooler from Midea (model Air Cooler 7.0 Liter AC120-U). I didn’t buy both at the same time. Initially, I purchased the air cooler because it was more affordable, especially when I had a baby.
My initial experience with the air cooler was disappointing because the air produced was not very cold, especially when my child felt hot.
However, after moving to a new rental, I began to feel that the air conditioner was more effective. I suspect this was because the ceilings in my previous rental were lower. With a low ceiling, the air felt hotter, and the cooling from the air conditioner was less effective.
After that, I finally decided to buy an AC; the cooling effect was felt much quicker. I usually set the temperature to 22 degrees, which is quite comfortable. I have been using both devices for about 5 years. The AC and air cooler can provide cool air, but the best choice depends on your needs and budget.
In my experience, the air conditioner is more effective in homes with high ceilings. After moving to a house with higher ceilings, the air conditioner worked much better even though the room size was the same. So, if you are considering buying an air cooler, consider the height of the room’s ceiling for optimal cooling results.
