The air handling unit (AHU) is the central component of the HVAC system in a building. It draws air in from the outside, filters it to remove particulates like dust and pollen, adjusts the temperature to the desired setting, and then uses ductwork to distribute the air throughout the structure. AHUs also aid in regulating air humidity, which promotes comfort and high-quality indoor air. Consider them as the unseen workers who maintain the perfect, comfortable, and clean air in your house or place of business.
