Duct Cleaning

Wetheads,
Since I have a mental block against scorched air anyway, I am curious as to how the new rave duct cleaners go about cleaning the often used fiberglass duct board dutwork and the circular type ???
Won't that procedure tear apart the fiberglass and create problems on the interior of the ductwork??
Everyone in the hot air business seems to be adding duct cleaning these days as an add on before installing new furnaces or as a scheduled maintenance type service.
I need to be educated ,can you enlighten me?

    I was curious when I read the above post about cleaning duct board also. A rotary brush like that seems like it would be a little rugged on the fiberglas. Do you know if any ductboard mfrs. have procedures that they recommend?

    Hi Steve, Actually if you're referring to the picture of the tool at the web site I posted? I would agree that looks like it would cause damage to a duct system. I just picked a random site to offer the gentlemen above some information on duct cleaning.

    In the past a couple jobs I was on that involved cleaning duct board we used what was called a whip. This was a device that had 5 or 6 soft nylon or rubber tubes each about 18 to 20 inches long. You would connect that to some flexible tubing that would be fed through the duct system as you were feeding it through you would be able to control air pressure as the air pressure was introduced and increased the nylon/rubber tubes would of course start whipping around the duct system blowing air at the same time. this action would cause the dirt/dust to break free.

    While all that was taking place you would have the duct supply or return blocked off at the appliance above your block you would tie a 14" Vacuum hose that would pull all the particles you were breaking loose through the system and deliver them to your out door duct cleaning unit.

    Well, I hope that explanation helps a little. Please keep in mind I only did this a couple times so most this information is based on memory. And I have a short memory :)
