What issue can occur in air conditioning systems that do not control air quality?

Sick building syndrome refers to a situation where occupants of a building experience health issues and discomfort that are linked to the time spent in that building, often associated with indoor air quality problems. In air conditioning systems that do not effectively control air quality, a variety of contaminants such as dust, mold spores, volatile organic compounds, and other pollutants can accumulate.

When ventilation is inadequate or when air filtration is poor, these pollutants can build up to levels that cause various health effects, resulting in sick building syndrome. The symptoms may include headaches, dizziness, eye irritation, respiratory issues, and fatigue, often improving when individuals leave the building. Thus, maintaining proper air quality through adequate ventilation, filtration, and humidity control is essential to prevent such health-related concerns.
