PERMACOLD ENGINEERING, INC.

Permacold Engineering, Inc. specializes in high-precision HVAC system repair, refrigeration component rebuilding, and marine environmental control system maintenance. Their technical expertise centers on ammonia-based refrigeration systems, including compressor overhaul, refrigerant circuit restoration, and cryogenic cooling infrastructure servicing. The contractor demonstrates deep proficiency in industrial-grade HVAC applications for mission-critical environments, particularly where hazardous refrigerants and stringent operational reliability are required. Their work on dredge vessel air conditioning systems indicates advanced capability in marine HVAC integration, including vibration damping, saltwater corrosion mitigation, and integrated control system diagnostics—skills critical for naval and maritime infrastructure. The company has delivered services to the Department of Agriculture and the Department of Defense, suggesting a focus on federal facilities requiring robust thermal management solutions. For the USDA, they have performed specialized ammonia compressor rebuilding, indicating experience with food processing, cold storage, and agricultural research facilities. For the DoD, their work on the Dredge Essayons points to direct support of U.S. Army Corps of Engineers maritime assets, underscoring their ability to operate in austere, high-humidity environments with complex mechanical systems. Permacold’s primary industry focus is in NAICS 238220, where they provide commercial and federal HVAC contracting with an emphasis on industrial refrigeration, and NAICS 336611, where they deliver shipboard environmental system repairs. This dual focus positions them as a niche provider bridging heavy industrial HVAC and naval maintenance markets, serving applications where conventional HVAC contractors lack the technical depth for ammonia systems or marine integration. As a small business structured as a 2L entity based in Portland, Oregon, Permacold operates without federal certifications but maintains a targeted geographic footprint in the Pacific Northwest with direct access to federal maritime and agricultural infrastructure. Their operational model emphasizes specialized mechanical expertise over broad service breadth, making them a trusted partner for complex, low-volume, high-reliability government projects.
