What is the primary purpose of air duct cleaning?

To increase humidity in the building
To improve energy efficiency
To reduce allergens and contaminants
To enhance aesthetic appearances

The correct answer is: To reduce allergens and contaminants

The primary purpose of air duct cleaning is to reduce allergens and contaminants. Over time, air ducts can accumulate various debris, dust, mold, pollen, and other pollutants that can negatively impact indoor air quality. These allergens and contaminants can circulate through the air system, leading to respiratory issues and allergic reactions among occupants. By effectively cleaning air ducts, the concentration of these harmful particles is diminished, creating a healthier environment and enhancing the air quality within the building. While improving energy efficiency is also a significant benefit of clean air ducts, as dirt and debris can obstruct airflow and force the HVAC system to work harder, the central focus of air duct cleaning is directly related to the health implications of airborne pollutants. Other options, such as increasing humidity or enhancing aesthetic appearances of ducts, are not primary concerns associated with the practice of air duct cleaning.
