HVAC installation in Sant Cugat del Vallès
HVAC installation and renewal in offices, schools and residential buildings in Sant Cugat del Vallès, with works planned around how each building is used.
In Sant Cugat del Vallès, most HVAC installations are not carried out on an empty site but in buildings in use: office floors changing tenant, schools that can only stop during the holidays, and residential buildings where every decision goes through the community. MRS Climatización designs, installs and commissions HVAC systems in the town, planning the works around when and how each building can be worked on.
Office refits between tenants
Many office buildings in the town run on VRF with centralised controls. When a floor changes tenant or layout, the HVAC has to adapt to new offices, meeting rooms and open-plan areas, often in the short window between one occupant leaving and the next arriving. The work includes:
- Reviewing which parts of the existing system can be reused: outdoor units, pipework and controls.
- Relocating or adding indoor units to suit the new layout.
- Integrating the changes into the central controls and documenting the new zones.
- Coordinating the works with the owner and the building's other tenants.
The differences between solutions are explained under VRF and fan-coil systems.
Schools: works in the holidays
Sant Cugat has many schools and education centres, and for them the works usually have a fixed window: the summer holidays. To make use of it, the diagnosis and proposal need to be finalised early, and equipment and materials planned before term ends. If the scope does not fit into a single shutdown, it is split into phases. Ventilation and air quality in busy classrooms are part of the study from the outset.
Residential buildings
In residential buildings and communities the constraints are different: where outdoor units go on the roof or in shared spaces, noise towards nearby homes, the community's or owner's authorisation, and later access for maintenance. In some cases aerothermal heat pumps are studied as an alternative to combustion systems, taking into account emitters, outdoor space and electrical supply.
Sizing for hot summers
Separated from Barcelona by Collserola and with less influence from the sea, Sant Cugat has hotter summers than the city centre. Load calculations start from those conditions, from orientation and from glazing, which is common in more recent offices. Outdoor units are selected to run with headroom at those temperatures, with enough space around them to avoid recirculating hot air. The electrical supply and panels are reviewed in the same study, because MRS also carries out the electrical work.
Organising the works
Materials and equipment are prepared at the MRS production and warehouse base in Sabadell, a short distance from Sant Cugat, and the project is administered from the Barcelona office. Before work starts, the delivery route for equipment, where materials can be stored on site and how roofs and common areas will be protected are agreed with the building's management. Work that cannot be done with the building occupied can be scheduled out of hours, arranged in advance. The general method is described under HVAC installation for buildings. On completion, the equipment is documented and labelled so it can move straight into HVAC maintenance in Sant Cugat.

Frequently asked questions
Can the existing VRF be reused when refitting an office floor?
Often, in part. We check the condition of the outdoor units, the spare capacity, the refrigerant and the pipe routes. If the system has headroom, relocating or adding indoor units and reconfiguring the controls may be enough. If it is at its limit or old, replacement is assessed, with its pros and cons.
Can a school's works be done entirely in the summer holidays?
It depends on the scope. A phased renewal can fit into the holidays if the diagnosis and proposal are finalised in good time, and equipment and materials are planned before term ends. If the scope does not fit into one shutdown, it is split across several holiday periods, leaving each phase in service.
Where do outdoor units go on a residential building?
Usually on the roof or in shared plant areas, with the community's or owner's authorisation. We assess noise towards nearby homes, airflow around the units, the load on the roof and access for maintenance. The location is set out in the proposal before works begin.
Will the electrical supply need upgrading for the new system?
It depends on the power the equipment needs and what the building already has. The diagnosis reviews the available supply, the condition of the panels and the protection devices. As we also carry out electrical installations and panels, any changes needed can be made within the same project.
How does summer heat affect system sizing?
In Sant Cugat summers tend to be hotter than in central Barcelona, so load calculations should start from the town's actual conditions, as well as orientation and glazing. We also check that the selected outdoor units will run with headroom at those temperatures.
