Flex Duct? and mold?

Is flex duct more likely to harbor mold and allergens? How long does flex-duct last? Is sheet metal worth the extra cost?

Flex duct tend to have more turbulence because the interior is not as smooth as hard pipe.  This leads to more fan energy needed per volume of air moved.  I have not heard of a significant difference with regards to molds and allergens, but it is more difficult to clean and therefore more likely to provide "habitat".  Properly installed, I do not know of that there is much of a difference with regards to service life - but there is probably some difference as the material is more vulnerable to physical damage.  - Ron Flax
