Buying an air conditioner might seem complicated, but with the right information, you can make the best choice for your needs. Here is a detailed guide to help you choose the right air conditioner.

Normal Capacity (BTU)

The main feature to check before purchasing an air conditioner is the Nominal Capacity or Power, measured in BTU/h. The easiest rule to remember is that the higher the BTU, the larger the space it can cover. Since each space in your home/store/company has different sizes and uses, here are some factors that can affect the power of an air conditioner:

  • The square footage and height of the space
  • The presence of building insulation
  • The floor on which it is located
  • The orientation and position of the rooms
  • The presence of other electrical appliances in the space

The table below correlates BTU with the square footage of the space:


9.000 - 11.000 BTU/hUp to 18m2
12.000 - 17.000 BTU/h18 - 25 m2
18.000 - 23.000 BTU/h25 - 40 m2
24.000 BTU/hOver 40 m2

Energy Class

The energy class ranges from A+++ (highest, most efficient) to D (lowest, least efficient). All models have two energy class levels, differing between cooling and heating. For cooling, it is referred to as the Seasonal Energy Efficiency Ratio (SEER), and for heating, it is referred to as the Seasonal Coefficient of Performance (SCOP). The higher the index, the more efficient the air conditioner is in that function. Therefore, if you are interested in using your air conditioner more during the summer months, you will focus on SEER, and if you use it more during the winter months, you will focus on SCOP.

Functions & Features

  • Smart Airflow: Thanks to smart airflow, in cooling mode, the air is directed towards the ceiling. In heating mode, the warm air is directed towards the floor.
  • Wi-Fi: Various connection and control options allow you to have full control of the unit at any time via the special app. In WiFi Direct, the unit has a built-in transmitter and receiver, while in WiFi Ready, an adapter purchase is required.
  • Sleep Mode: Your air conditioner will automatically adjust the temperature and fan speed to make the room quieter, more pleasant, and comfortable during the night.
  • Super Ionizer: The Super Ionizer eliminates odours, dust, smoke, and pollen particles by releasing anions and cations, providing fresh and healthy air.

Types of Air Conditioners
There are various types of air conditioners, each with its own advantages and disadvantages:

  • Split Air Conditioners: Consist of an indoor and an outdoor unit. Ideal for home use and offer high performance.
  • Multi-split Air Conditioners: Can connect multiple indoor units to one outdoor unit, providing uniform heating and cooling. Ideal for air conditioning in multiple rooms or very large rooms.
  • Portable Air Conditioners: Easy to move and install, suitable for small spaces.
  • Window Air Conditioners: Installed in windows and are economical but can be noisy.

Cost & Installation

A key requirement for the effective operation of your air conditioner is its installation by experienced technicians to avoid potential issues such as poor performance, excessive energy consumption, and loss of warranty. The main factors to consider are:

  • Avoid installing the air conditioner on walls exposed to direct sunlight, as this increases energy consumption.
  • Avoid placing the air conditioner near heat sources, such as the kitchen.
  • It is recommended that the airflow direction does not target busy areas, such as the sofa, dining table, or bed, to avoid direct exposure.
  • The outdoor unit should be placed on a sturdy bas in a shaded area, with easy access for maintenance and the necessary free space around it for ventilation.
  • Silent Operation or Sleep Mode is recommended for air conditioners installe in bedrooms.

Maintenance & Cleaning

The maintenance and cleaning of the air conditioner are crucial for its performance, energy consumption, and the quality of the air produces. Filters should be cleaned frequently and replaced as recommended by the manufacturer. Maintenance should be performed by specialised technicians once a year.
