Air Systems Cleaning Specialist (ASCS) Practice Exam

Ignoring regularly scheduled duct cleaning can lead to an increase in hazardous pollutants within the air distribution system. Over time, dust, debris, mold, and other contaminants can accumulate in the ductwork. When the ductwork is not cleaned regularly, these contaminants can be circulated throughout the indoor environment, posing health risks to occupants and reducing overall air quality. As pollutants build up, the efficiency of the heating, ventilation, and air conditioning (HVAC) system can also be compromised, leading to issues such as increased energy consumption and the potential for system malfunctions. In contrast, regular duct cleaning helps to maintain a clean and efficient air distribution system, contributing to a healthier indoor environment and better overall system performance. By neglecting this aspect of building maintenance, not only is the system's efficiency jeopardized, but the well-being of the occupants is also put at risk due to increased exposure to harmful pollutants.
