Air duct cleaning incorporates the removal of dust, debris, and other contaminants from the HVAC ductwork. This includes the supply and return air ducts, along with the registers and diffusers in each room. With time, these ducts may accumulate a large quantity of dust and debris, even facilitating mold growth if moisture is present. This can lead to reduced air quality inside the property, which may contribute to health disorders among the occupants, especially those with allergies or respiratory disorders.
