Post-Construction HVAC Cleaning Jersey City Public Library
Client: Jersey City Public Library (historic downtown branch) Scope: Remove all construction dust from supply and return ductwork after the remodel.
Unique Challenge
The building’s interior layout ruled out using a traditional duct truck. Staircases are narrow, rooftop access is limited, and much of the ductwork runs across high ceilings, so we had to rely on indoor solutions and scaffolding to reach every section.
WellDuct’s Solution
- Dual HEPA Negative-Air Machines
• We set up two industrial HEPA-filtered negative-air machines inside the building to create the suction usually supplied by a truck. Custom ducting ran through mechanical rooms and stairwells without blocking public exits.
- Scaffold Access & Sectioned Cleaning
• Our crew erected mobile scaffolds in reading rooms and atriums to reach ceiling diffusers and duct connections tucked above the décor. • Each duct run was mechanically agitated and vacuumed in segments, ensuring that fine drywall dust and construction debris were fully removed.
- Air Handler & Terminal Device Detailing
• Central air handlers, coils, and drain pans were cleaned and treated, while registers, grilles, and diffusers were taken down, washed, and reinstalled. • Scaffolding allowed us to keep the work tidy and safe around the recently renovated architecture.
- Night/Off-Hour Schedule & Documentation
• Work was phased during nights and closed hours, so patrons never had to step around equipment. • We provided a detailed log and photo set for the city’s construction close-out requirements.
Results
• Despite the constraints, the entire HVAC system was restored to post-construction cleanliness. • Air sampling showed particulate levels dropped to normal background within one air-change cycle. • The library reopened with fresh, dust-free ventilation—without ever needing a duct truck on site.
