Air Conditioners: What to Consider for the Perfect Purchase

When it comes to cooling your space, air conditioners are the ultimate machines. In this comprehensive guide, we will focus on air conditioners that provide cooling, although it's worth mentioning that some models also offer heating capabilities through a heat pump. Gain insights into the functioning of air conditioners, explore various types available, and discover essential tips for a successful purchase.

Understanding Air Conditioners:

Air conditioners work by utilizing a special gas, typically R32 gas, which undergoes a cycle of compression and decompression to regulate temperature. The gas, in its liquid state, reaches the internal mechanism of the air conditioner, known as the "split." The internal unit intakes hot air from the environment and expels cool air through a fan, ensuring a comfortable temperature.

Types of Air Conditioners:

  1. Air Conditioner without External Unit: This type of air conditioner is ideal for those who value aesthetics and wish to avoid installing an outdoor unit. The market offers fixed air conditioners with excellent energy efficiency ratings (usually A+++), resulting in reasonable energy consumption and potential savings, especially when choosing an inverter air conditioner.

  2. Portable Air Conditioner: Portable air conditioners are perfect for individuals who prefer not to install a large outdoor unit. The only bulkier element is the exhaust pipe, which can be efficiently directed outside using ventilation holes or universal gaskets for air conditioner windows. The gasket option avoids the need to drill walls.

  3. Fixed Air Conditioner: Fixed air conditioners offer reliability and superior cooling efficiency, although they require installation space outside, such as a balcony or terrace. This type of air conditioner operates quietly, ensuring minimal noise inside the house. Additionally, fixed air conditioners can also provide heating, replacing traditional heating systems.

Considerations for Power:

Determining the right power capacity for your air conditioner is crucial for optimal performance. Power is measured in British Thermal Units (BTUs) and depends on the square footage of the area you want to cool. The recommended power range is typically between 9,000 and 12,000 BTUs. To calculate the required BTUs, multiply the square meters of your room by 340 (the coefficient representing the approximate BTU needed per square meter).

Important Advice:

Regardless of the type of air conditioner you choose, it is advisable to set the temperature at a reasonable level. A temperature of around 25°C is ideal, or it should not be set more than 6 to 7°C below the outside temperature to avoid excessive energy consumption. Extremely low temperatures can lead to health issues such as headaches and colds.


Purchasing the right air conditioner involves considering your specific needs and preferences. By understanding the different types available, evaluating the appropriate power based on room size, and following temperature guidelines, you can make an informed decision. Stay cool and comfortable throughout the summer season with the perfect air conditioner for your space!
