Flex ducts are good for air quality because you are not breathing in fiberglass insulation lined ductwork like the Fiber Air Ducts and they are mold and rust resistant unlike galvanized sheet metal ductwork.Is Air Duct Cleaning worth it?
Duct cleaning has never been shown to actually prevent health problems. Neither do studies conclusively demonstrate that particle (e.g., dust) levels in homes increase because of dirty air ducts. This is because much of the dirt in air ducts adheres to duct surfaces and does not necessarily enter the living space.Can you have too much return air?
