To any of the people that have had their FLEXIBLE air ducts cleaned, I would like to hear exactly how this was done to avoid damage to the ducts, like a tear or puncture. I have looked at the duct work in our attic and i see no way this can be done safely. The hose has to be rigid enough to be pushed through the ducts, but flexible enough to follow the routing of the duct work Pictures would be great, at least a detailed description of the equipment and methods used.
