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, etca€| 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 a€?before condition and after a€? conditions of the duct.
