Air duct cleaning refers to removing dust and other buildup from HVAC systems. Having air ducts cleaned when necessary helps prevent potential health problems and maintains system efficiency.
Particulate matter that collects in ducts has not been conclusively linked to health issues, although it can serve as a breeding ground for mold, which can lead to expensive repairs and potential health problems if left untreated.
Air ducts are more efficient when their walls are as smooth as possible, and particulate matter that collects can lead to inefficient airflow. The reduced size of ducts also leads to inefficiency. Occasionally cleaning ducts and other HVAC components leads to better system efficiency.
