The expense associated with sealing and coating the interior of air ducts to prevent the release of fibers or contaminants is a significant consideration for property owners. This expenditure encompasses labor, materials (sealants, coatings), and potentially, diagnostic testing to identify problematic areas within the ductwork. The total amount varies depending on the size of the duct system, its accessibility, the chosen encapsulation method, and regional labor rates. For example, a modest residential system might incur charges in the hundreds of dollars, while a large commercial building could face costs extending into the thousands.
Addressing air quality concerns and energy efficiency are frequently cited advantages. Encapsulation can curtail the spread of mold spores, asbestos fibers (if present), and dust particles throughout a building. Moreover, by sealing leaks and gaps in the ductwork, HVAC systems operate more effectively, potentially lowering energy consumption and associated utility bills. Historically, this practice gained traction as awareness grew regarding indoor environmental quality and the impact of deteriorating duct systems on building occupants’ health and comfort.
