A healthy room climate is not a coincidence of the best chances but the outcome of thoroughly considered choices and solutions.
All ducts and parts of the air handling system must be clean to ensure the cleanliness of air inflow. Contaminants accumulated in the air handling system can affect air quality in the rooms and decrease air volumes. The precondition for a good room climate is correct use of the building and its communications.
Ventilation duct systems are equipped with maintenance doors, placed in well accessible areas.
