Ventilation
Filters, fans, automation, actuators, dampers, grilles, airflows, noise, access points, and cleanliness of accessible system sections.
Ventilation and air conditioning system maintenance
What maintenance includes for Ventall-built ventilation, air conditioning, VRF / VRV, chiller, automation, filtration, and drainage systems.
Service
Ventall services its own implemented systems
Ventall maintenance is not a general repair service for third-party air conditioners. It is tied to facilities where the team knows the design, routes, equipment, automation, access points, and commissioning setup.
Service format
Service is tied to an implemented system
Maintenance makes sense when the service team understands how the system was designed, installed, and commissioned. For Ventall, this means facilities implemented by Ventall: from apartments and houses to offices, stores, production spaces, VRF / VRV or chiller systems.
This format is important for service quality: the team works with a known system layout, equipment, routes, automation, access points, and previous system settings.
Checks
What is usually checked during service
- Filters, heat exchangers, fans, electrical connections, sensors, and automation.
- Drainage, condensate, alarm signals, noise, vibration, and access to service areas.
- Airflow rates, balancing, cleanliness of grilles, diffusers, chambers, and accessible parts of the system.
- For VRF / VRV systems, chillers, and refrigerant circuits, work should follow approved procedures, equipment documentation, and the qualification of the service team.
- Service frequency cannot be defined by one number for every system: once per year is a basic minimum guideline, but specific equipment or operating conditions may require more frequent service.
Systems
Different systems have different service logic
Air conditioning and VRF / VRV
Heat exchangers, drainage, outdoor and indoor units, sensors, operating modes, alarm signals, and service operations specified in the equipment documentation.
Chillers and fan coils
Hydraulics, automation, filters, drainage, pumps, temperature modes, fan coils, and service access to equipment.
Standards and checks
Procedures, equipment documentation, and system checks
A service visit should be based on the service procedure, equipment documentation, system condition, and operating conditions. Internal reports and checklists are used to record completed checks and recommendations, but they do not replace design documentation or equipment documentation.
During service, general requirements for heating, ventilation, and air conditioning are considered, including DBN V.2.5-67:2013, as well as documentation for the specific facility. EN 12599 / DSTU EN 12599:2025 are useful for the logic of system checking and handover, EN 15780 for ventilation system cleanliness, and EN 12097 for access to air ducts and inspection openings.
Exact filter replacement intervals, service operations, and work on the refrigerant circuit must come from equipment documentation, operating conditions, and the service contract.
Next
When to plan service
If the system has been implemented by Ventall, service is planned as a continuation of the project: the team knows where the routes pass, where the equipment is located, how the automation works, and which service access points were provided.
If the system has not yet been implemented, service access must be planned at the design and installation stage, not searched for after commissioning.
