Air handling refers to the process of regulating and circulating air in a building. This involves the use of equipment such as air handling units (AHUs) that filter, heat, cool, and distribute air throughout a space. Proper air handling ensures a comfortable indoor environment and maintains air quality by removing pollutants and controlling humidity levels. In commercial and residential settings, effective air handling is crucial for energy efficiency and occupant comfort. Systems are designed to meet specific needs, often incorporating HVAC (heating, ventilation, and air conditioning) components. Regular maintenance of air handling systems is essential for optimal performance and longevity.
