Air conditioner installation: essential thermal comfort

An air conditioner installation in Brussels is essential during periods of intense heat. Whether for offices or homes, air conditioners cool and filter the air. With a reversible system, you can even heat your interior. The system relies on two units: one outdoor unit that produces the air, and one indoor unit that distributes it.

Everything you need to know about installing an air conditioner in Belgium

Installation of a split air conditioner in Brussels

The installation of an air conditioner in Brussels, particularly the split model, remains one of the most popular choices among Brussels residents. This type of system consists of two separate units: an indoor unit (often mounted high on a wall) and an outdoor unit placed on the facade, on a balcony, or on the ground. This system is ideal for cooling a main room, such as a living room, bedroom, or office.

One of the major advantages of installing a split air conditioner in Brussels is its simplicity: with minimal work, you enjoy excellent thermal comfort during summer periods. Additionally, this type of air conditioning is generally quieter and more aesthetically pleasing than a portable model.

In Belgium, where heatwaves are becoming more frequent, residents are seeking sustainable solutions. This is why the split air conditioner is a wise investment, particularly in the typical apartments or terraced houses of Brussels. It is recommended to hire a certified professional to ensure an installation that complies with Belgian standards, particularly regarding insulation, electricity, and safety.

Installation of a multisplit air conditioner in Brussels and Belgium

If you want to air condition several rooms at once—for example, a living room, bedrooms, and an office—the multisplit system is the ideal solution. This setup relies on a single outdoor unit connected to multiple indoor units. This allows for room-by-room temperature control, providing personalized comfort for every family member.

De installatie van een multisplit-airconditioning in Brussel vereist meer planning dan het split-model. Er moet een netwerk van koelleidingen worden voorzien dat elke binnenunit met de buitenunit verbindt, wat afhankelijk van de indeling van uw woning aanzienlijke werkzaamheden kan vergen. But once installed, this system ensures efficient and quiet cooling throughout the house.

In Belgium, this solution is very popular in medium to large homes, but also in offices and small hotels. Thanks to recent technologies, these systems can also offer a reversible mode for heating rooms in winter—a significant advantage in Belgium’s often variable climate.

Hiring a company that specializes in installing multi-split air conditioners in Brussels is essential to guarantee high-quality work, with certified equipment and reliable after-sales service.

Installation of portable air conditioners in Brussels: a practical and flexible solution

Mobile air conditioners are an excellent alternative for those looking for a temporary, economical solution that does not require major work. This type of device does not require a fixed installation: simply plug it into an electrical outlet and point it toward the room you want to cool.

However, to ensure proper operation, venting the hot air is essential. In Brussels, this is typically done through a partially open window using a sealing kit, or through an exhaust duct installed in a wall or door.

Installing a portable air conditioner in Brussels is particularly suitable for tenants or for occasional use during periods of high heat. Although less efficient than split or multi-split systems, portable air conditioners remain a quick and affordable solution for improving indoor comfort.

In Belgium, many models are available for purchase or rental. It is advisable to choose a unit suited to the room’s size and to ensure its energy efficiency to avoid excessive consumption.

8 steps to successfully install air conditioning in Brussels and Belgium

The installation of a fixed air conditioner generally follows these steps:

Strategic selection of locations

The first step, often underestimated, is crucial: determining the optimal locations for the indoor and outdoor units. This is done in collaboration with your Brussels installer, who will analyze your home’s layout.

L’unité intérieure doit être placée à plus de 2 mètres de hauteur pour assurer une bonne diffusion de l’air frais.
Le mur choisi doit être solide et accessible afin de supporter le poids de l’appareil et de faciliter la maintenance future.

The outdoor unit must be placed sheltered from prevailing winds and direct sunlight, while remaining easily accessible for technicians.

Tip for Brussels residents: if you live in an apartment building, remember to consult your property manager before installing the outdoor unit.

Installing the indoor units

Once the locations have been confirmed, the installer mounts the indoor units on the wall or in a false ceiling, depending on the model chosen (wall-mounted, console, built-in). He then drills holes to allow passage:

  • Electrical cables

  • Refrigerant pipes

  • The condensate drainage system

In Brussels, where many buildings are old, this step often requires special adjustments to preserve existing structures. The use of decorative ducts ensures a clean and attractive finish.

Installation of the outdoor unit

The outdoor unit, the heart of the system, is installed on a concrete base, a wall bracket, or a secure balcony. She must:

  • Have adequate air clearance around it

  • Be protected from excessive rain and direct heat

  • Be isolated from neighbors (mind the noise in Brussels’ residential areas)

In Belgium, environmental and acoustic standards are strict. The installer therefore ensures compliance with minimum distances and neighborhood regulations, particularly in dense urban areas like Ixelles, Uccle, or Schaerbeek.

Connecting the refrigerant lines

Insulated copper pipes carry refrigerant between units. They are carefully installed to ensure watertightness and optimize energy performance. Installation options vary depending on the configuration:

  • Surface-mounted conduit with discreet casing

  • Chasing into the wall or ceiling

  • Running through a false ceiling or attic space

In Brussels, professional installers take care to integrate these pipes into aesthetic solutions, especially in modern interiors or renovated homes in the city center.

Secure electrical connection

The fixed air conditioner requires a precise connection to your home’s electrical system. This step includes:

  • Installing a dedicated circuit breaker for added safety

  • The connection between the outdoor unit and the indoor units

  • Compliance with Belgian electrical protection standards (RGIE)

In Brussels, certified professionals possess the necessary certifications to guarantee an electrical installation that complies with local and national requirements.

Installation of condensate drain pipes

Each indoor unit generates condensation during operation. Therefore, it’s essential to install a drainage system:

  • Either by natural gravity to a drainage point

  • Or using a condensate pump, especially during renovations or in apartments

In Brussels, where space is sometimes limited, the installer must be creative to ensure a system that is both invisible and efficient, with no risk of leaks or backflow.

Commissioning and comprehensive testing

Before any use, several technical tests are carried out:

  • Pressure test to detect potential leaks

  • Refrigerant circuit purge to remove air and moisture

  • Refrigerant level check

  • Complete operational test (startup, temperature setting, airflow, noise)

In Brussels, some neighborhoods may have specific electrical constraints, particularly in older buildings. The technician will take this into account to prevent any issues after commissioning.

Site cleanup and usage instructions

After installation, the team thoroughly cleans the site: drill holes, saw cuts, dust… everything is tidied up. You will then receive:

  • Maintenance instructions to extend the air conditioner’s lifespan

  • Usage recommendations to save energy (eco mode, programming, cleaning filters)

  • Technical documentation with warranty

This is when you can fully enjoy your new air conditioning installation in Brussels, with complete peace of mind.

Maintaining your air conditioning isn’t just useful, it’s mandatory to ensure the unit’s efficiency and longevity.

This is a necessary step to ensure that your system works properly and to prevent any malfunctions. If your system is well maintained, it will consume less energy and distribute healthier air.

Reversible air conditioning maintenance: when and how often?

The frequency of maintenance for a reversible air conditioning system depends on its model. If you have units capable of purifying the air or deodorizing it, you should maintain the purifier every three months and the deodorizer approximately every two to three years.

In any case, if the refrigerant in your reversible air conditioning system exceeds 2 kg, annual servicing by an approved professional is mandatory.

Our company employs certified professionals who hold the following certificates:

  • the Brussels Institute for Environmental Management (IBGE)
  • Basic Safety Certificate VCA
  • Training in electrical safety and risks BA4 and BA5
