The American Lung Association's position on duct cleansing affirms the EPA's statement and suggestions, however adds: When illness are believed to be the outcome of biological pollutants or dust in indoor air, it is necessary to first identify that polluted ducts are the cause of the health issues and confirm that the ducts are, in truth, contaminated.

That's misleading. Although much of the energy used to power heating & cooling devices is undoubtedly lost, that waste is because of inefficient devices, lousy insulation, leakages around windows and doors, and unsealed ductwork.

Versatile coil-style ductsthe kind that looks like a Slinky toyare more vulnerable to being pierced. Ductwork fabricated from fiberglass-insulated materialwhich is cheaper than metal ductworkhas become more common in new houses. These ducts have fiberglass insulation on their interior surface areas.
