Most of the work people perform in closed rooms. However, proper attention previously has not been directed to the problem of people working in offices without natural ventilation. The subject of this study is the influence of the HVAC system on health, working ability, absenteeism and the satisfaction of people working in an office without natural ventilation. There is no known ergonomic research that previously dealt with this topic, taking into account the above-mentioned specificity. A case study was conducted, which included fifteen employees of a branch of a company engaged in the provision of telecommunication services. Employees in the branch office of this company perform tasks in several rooms where no natural ventilation is applied. In view of this, special attention is paid to the practice of maintaining the HVAC system. An original questionnaire specially formulated for this purpose was used, which was answered by the staff of the company that maintains the HVAC system for the mentioned company. In addition, an adapted general health questionnaire was used, which also included issues related to the impact of the work environment on working ability and the satisfaction with the existing air quality. The results of the conducted research show what are the most pronounced health problems of the workers. It is concluded that in order to maintain the health of workers in offices without natural ventilation, a comprehensive approach is required, which involves more strict air control that involves additional measurement of certain parameters of the air quality in regular intervals, as well as additional education of staff of firms who maintain HVAC systems.
