HVAC and technical maintenance for offices

HVAC, electrical and maintenance services for office buildings: open-plan zoning, meeting rooms, tenant fit-outs and work coordinated with business hours.

In an office building, HVAC is mostly noticed when it goes wrong: cold complaints by the façade, stuffy meeting rooms in the afternoon or an electrical board tripping in the middle of the working day. MRS Climatización works with landlords, property managers and facilities managers in Barcelona, its metropolitan area and Sabadell to install, maintain and adapt office HVAC and electrical systems to how the space is really used, with as little disruption as possible to the people working there.

Open-plan floors and zoning

Most comfort complaints in offices are not caused by a breakdown but by zoning that no longer matches how the space is used. Typical findings include:

  • Zones that combine a sunny façade with interior space, controlled by a single thermostat.
  • Temperature sensors mounted above a printer or next to a window.
  • Diffusers blocked by cabinets or partitions added later.
  • Airflows that drifted out of balance after desks were rearranged.

Before proposing any work, we measure temperatures, airflows and set points zone by zone and compare them with the complaints log. Rebalancing or adjusting controls often achieves more than replacing equipment.

Meeting rooms and high-density spaces

Meeting rooms, training rooms and break-out areas concentrate people and equipment for short periods. Their heat load changes quickly, and if they share a unit with the open-plan floor they end up poorly served. Options range from separate control to adding indoor units on a VRF system or reviewing the room's ventilation. Comms rooms also need continuous cooling and their own monitoring.

Tenant fit-outs and layout changes

Every change of tenant or internal reconfiguration affects the floor's HVAC and electrical systems. Getting involved early avoids problems later:

  • Review of ductwork, diffusers and returns against the new layout.
  • Adaptation of zones and controls to new offices and rooms.
  • Extension or reorganisation of floor distribution boards and technical lighting.
  • Coordination with the landlord, project management and other trades.

For larger projects, our page on HVAC installation for buildings explains how the work is organised. Our published projects include an office refurbishment in Alta Diagonal (Barcelona) and, in a public building, the replacement of the HVAC system for the whole of Biblioteca Can Mulà.

Working within business hours

Office occupancy is predictable, which makes good planning possible. Preventive inspections are spread across zones and announced to occupants; work that needs a supply shutdown, access to ceiling voids above occupied desks or that generates noise is grouped into slots agreed with the landlord. Our hours are Monday to Friday, 9:00 to 18:30, and the conditions for each service are set in the contract.

When a fault occurs, it is diagnosed on site with measuring equipment and, wherever possible, repaired in the same visit. You can read how we approach this on our HVAC fault diagnosis and repair page.

Multi-tenant buildings

In multi-tenant buildings it pays to separate common services clearly from the equipment in each let space. A well-structured maintenance plan defines what each party is responsible for, how often it is inspected and who receives each report. Having a single supplier for HVAC and electrical work simplifies that coordination, as we explain in one supplier, clearer accountability.

We are incorporating a digital platform with a record per unit, intervention history and detected incidents, making it easier to share the condition of the installation with landlord and tenants.

What to prepare for an assessment

  • Floor plans showing the current layout.
  • A list of HVAC equipment and electrical boards, if one exists.
  • A log of comfort complaints by zone and time of day.
  • Recent or planned refurbishments.
  • Building hours and the time slots available for work.

Frequently asked questions

Why is one part of the floor too cold and another too warm?

It is usually down to zoning that no longer matches the current layout: façades with different orientations in the same zone, thermostats in unrepresentative positions, diffusers blocked by furniture, or airflows left unbalanced after a refurbishment. Temperatures and airflows are measured zone by zone before any change to controls or plant is proposed.

What can be done about meeting rooms that overheat?

A small room full of people and screens has a far higher heat load than an open-plan desk. If it shares a unit with the open-plan area, it will never be served properly. We assess whether adjusting the controls is enough, whether the room should be zoned separately, or whether it needs its own unit, depending on the existing installation.

Can you work on a tenant fit-out?

Yes. We review how the new layout affects HVAC zones, ductwork and the floor's electrical distribution boards, and coordinate with the landlord and the other trades. The aim is that the fit-out does not leave areas unserved or unbalance neighbouring floors.

Can the work be done without disrupting the business?

In most cases, yes. Preventive inspections are carried out zone by zone, with advance notice to occupants. Work that requires a supply shutdown or is noisier is grouped into time slots agreed with the landlord or facilities manager. The specific schedule is set out in the proposal and the contract.

Can maintenance cover several tenants in one building?

Yes. The scope can be split between landlord-managed common services and the equipment within each let space, with separate reports. That way each party knows which equipment is theirs, which inspections have been done and which incidents remain open, and investment decisions can be made on clear information.
