What is the best way to have an air duct cleaned.
There seems to be a few choices.
1. there is strong vacuum stemming from a truck that vacuums
your duct system
2. some guy comes in with a strong hepa vacuum and uses negative air vacuum force to suck in all the materials from teh basement area where all the duct work starts.
3. some guy comes in with a rotobrush machine…and goes into each vent individually wiht a long hose and vacuums there…which is the best.
Thank you,
