Paul Keller, Jr., ASCS is a seasoned practitioner in mechanical system hygiene, industrial process restoration, and environmental remediation. Bridging the gap between specialized field execution and building science principles, Paul evaluates HVAC systems not in isolation, but as dynamic components deeply intertwined with building envelope pressure dynamics, airflow mechanics, and indoor air quality (IAQ).
Core Expertise & Specialized Operations
Paul’s technical focus centers on large-scale commercial, industrial, and high-density residential properties, bringing diagnostic rigor to complex mechanical environments:
Cooling Tower Hygiene, Maintenance & Risk Mitigation: A recognized specialist in central cooling tower operations, thermal performance, and biological risk assessments. Paul delivers comprehensive hygiene, maintenance, and diagnostic evaluations critical for multifamily developments and commercial facilities—ensuring efficient heat exchange, regulatory compliance, and proactive control against waterborne pathogens like Legionella.
Industrial Process Extraction & Airborne Containment: Advanced expertise in deep cleaning, restoration, and compliance maintenance for dust collection systems and paint spray booths, managing heavy particulate, combustible dust, and chemical residues.
Complex Air Distribution & Building Dynamics: Applying hygrothermal and air pressure principles to solve contamination issues within open-air plenums, sub-floor distribution pathways, and unducted return systems prone to particulate buildup and cross-contamination.
High-Hazard Field Safety: Comprehensive protocols for high-elevation rigging, fall protection, and multi-story industrial access.
Industry Leadership & NADCA Service
A long-standing advocate for elevated industry standards, Paul spent six years on the National Air Duct Cleaners Association (NADCA) Board of Directors, helping shape national guidelines for safety, ethics, and mechanical cleaning protocols.
Ethics Committee Leadership: Served as Chair of the NADCA Ethics Committee, fostering professional integrity and standard operating practices across the trade.
Technical Task Forces: Contributed directly to national safety initiatives, including fall protection standards and energy optimization strategies for mechanical systems. Professional Credentials
