Tell me how that ram air deal will remove a pop can, a dead mouse
a cabbage patch kid, a racoon or any thing bigger than a dime out of ducts?
Have you ever seen the hopper of a "real" Air Duct truck. The stuff
I see in it cant go through a 2 inch hose. How do you clean the return trunk line
in a ranch that is 120 feet long. How do you clean a return "the dirtiest part"
that is 40 feet in the air in a cathedral ceiling family room? We do it from the
basement. I just don't think you have any creditability if you don't use some
kind of negative air machine that sucks stuff out of the dwelling.
Here is an inexpensive way to get into air duct cleaning for around 8k
with out having to buy a 100k truck:
