They'll connect the hose of the vacuum gather device to a duct near the air handler. The technician will need to install an access door to enter.  

  

To enhance the negative pressure, close all of your supply registers. The personnel can then turn the vacuum on, and each duct gets cleared one at a time.  

  

3. Agitating the Dust
