VRV and VRF system maintenance

A list of indoor units alone is not always enough to organize the service. Each room or area needs to be linked to its outdoor unit, controller and circuit, alongside operating schedules and technical access points.

In an office with several tenants or floors, this map helps coordinate visits and distinguish a local fault from a shared system issue. It should be updated when spaces change or workstations are rearranged.

• Identification and location of indoor and outdoor units.
• Inspection of filters, drains, heat exchangers and unit ventilation.
• Alarm readings and control checks appropriate to the system.
• Records of comfort complaints by area and work completed.

Meeting rooms, work areas and restricted spaces have different needs. Depending on the task, visits can be organized by floor, time slot or outdoor unit.

Any task requiring a shutdown is coordinated with the building manager. Service requests should also specify entry restrictions, permits and access conditions for rooftops or plant rooms.

When a unit provides insufficient cooling or shuts down, the solution depends on the cause. Diagnosis considers alarms, component condition and operating circumstances. Work on the refrigerant circuit does not replace the need to identify a leak or another underlying fault.

The report should explain the finding and recommendation so management can choose between a repair, an operating adjustment or further monitoring. Compatibility and procedures are checked against the specific manufacturer documentation.

Provide the address in CABA or Greater Buenos Aires, make and model if available, numbers of indoor and outdoor units, occupancy hours and observed symptoms. Alarm codes and the time they first appeared provide useful context.

URBANARC prepares the maintenance scope around your inventory and building needs. The proposal distinguishes scheduled visits, corrective support and work outside the agreed scope.
