The AC duct will be cleaned using a HEPA filtered negative air Machine (Vacuum Unit) which will be connected to one end of the duct and from the other end we use a variety of tools like rotary brushes, air whips, nozzles, scrubbers, air compressor, etc… to agitate and loosen the dust and debris from inside the duct which is drawn into the vacuum unit and contained within. The other method involves a technician descending the ducts depending upon the contamination size & foreign particles, manually clean the duct.
An access is cut in the initial ducting (Main Duct)
Flexible duct from the HEPA vacuum is connected with a quick-connect attachment collar. The HEPA vacuum is then turned on to create inflow within the supply duct work
The Robotic camera in inserted into the duct to capture “before condition and after ‘ conditions of the duct.
