Duct & Vent Cleaning of America, Inc was hired to contact HEPA vacuum all of the existing supply, return and exhaust ductwork associated with RTU’s 2, 3 & 4. We also cleaned the three air handling units and all registers, grills, and diffusers. We then treated each of the three AHUs with a disinfectant cleaner labeled for use against SARS-CoV-2 or human Coronavirus.
