During this Duct Cleaning and Dryer Vent Cleaning project we contact HEPA vacuum one roof-top air handling unit, all air shafts and all diffusers/grills servicing the common hallways, laundry rooms & storage rooms in each of the three buildings. We also rotary brushed & HEPA vacuumed three four-story exhaust shafts servicing a total of 12 laundry rooms with one dryer in each room within all three buildings.
