CHUNG LIM CLEAN CO.,LTD.

Chung Lim Clean Co., Ltd. specializes in high-performance cleaning and maintenance services for critical building systems, with a focus on HVAC ductwork, chimney systems, and fan coil unit sanitation. Their technical expertise centers on nonhazardous waste removal and deep cleaning of air handling infrastructure within institutional and defense facilities, ensuring compliance with indoor air quality standards and operational continuity. The contractor delivers precision mechanical cleaning using industry-standard methods such as negative air pressure extraction, brush agitation, and vacuum-assisted debris removal, targeting contaminants that compromise ventilation efficiency and occupant health. Their specialization in duct and coil sanitation reflects a strong command of ASHRAE guidelines and facility hygiene protocols, positioning them as a trusted provider for mission-critical environmental maintenance. The company maintains a consistent relationship with the Department of Defense, delivering recurring cleaning services for military installations and government-owned buildings. Their work supports base readiness by sustaining HVAC system integrity, reducing airborne particulate loads, and minimizing mechanical downtime through proactive maintenance. All engagements involve direct support to facility operations, with a pattern of repeat tasking for high-traffic or sensitive areas requiring stringent cleanliness controls. Their primary industry focus lies in Nonhazardous Waste Treatment and Disposal (NAICS 562219) and Other Services to Buildings and Dwelling (NAICS 561790), which in practice translates to specialized building systems sanitation rather than general janitorial services. They serve as a niche provider for technical cleaning within defense and institutional infrastructure, filling a gap between routine maintenance and full-scale environmental remediation. Chung Lim Clean Co., Ltd. operates as a 2L entity based in Seoul, with no publicly listed government certifications. Their market presence is defined by targeted, repeat engagements with U.S. defense facilities, indicating a focused, contract-driven operational model rather than broad commercial outreach. Geographic reach is limited to U.S.-based DoD sites, with no indication of domestic or international service expansion beyond these assignments.
