Air duct cleaning is a fragmented home and commercial services industry focused on removing dust, debris, allergens, and microbial contaminants from HVAC ductwork to improve indoor air quality and system efficiency. The sector serves both residential homeowners and commercial property managers, with demand driven by health awareness, aging building stock, and post-construction or renovation cleanouts. Despite a historically poor reputation due to low-quality operators and consumer scams, certified and professionally run businesses with strong brands command premium pricing and loyal customer bases.
