What method is often used to prevent moisture accumulation in air ducts?

Regular inspection
Insulation application
Humidity control measures
Duct sealing

The correct answer is: Humidity control measures

Humidity control measures are essential for preventing moisture accumulation in air ducts. Maintaining optimal humidity levels within indoor environments helps reduce the chance of condensation forming inside the ducts. High humidity can lead to the growth of mold and mildew, which can negatively impact both air quality and the efficiency of the HVAC system. By implementing humidity control measures, such as utilizing dehumidifiers or enhancing ventilation, the moisture levels can be kept in check, thus protecting the integrity of the air duct system. While the other methods listed can contribute to overall system maintenance and efficiency, they do not specifically target the issue of moisture accumulation to the same extent as effective humidity control measures. Regular inspection helps identify potential problems but does not directly prevent moisture. Insulation application can reduce temperature differentials that lead to condensation but may not eliminate moisture altogether. Duct sealing is crucial for maintaining air quality and system efficiency but does not actively control humidity levels.
