To ensure the City of Chelmsford Senior Citizens are breathing in clean air, as a part of their commitment to healthy Indoor Air Quality, they hired Duct & Vent Cleaning of America, Inc. The project consisted of contact HEPA vacuuming each HVAC system in the building. All of the existing ductwork, including 6 air handling units located in attic and basement were cleaned as well as the registers, grilles, and diffusers throughout the building.
