What APEC does

APEC (Advanced Professional Engineering Consultants) is a private mechanical engineering consulting firm headquartered at 135 Enterprise Court in Corona, California, with approximately 29 years of operating history. The firm provides integrated mechanical (HVAC), plumbing, and process engineering design services to building owners, architects, and general contractors across commercial, industrial, healthcare, pharmaceutical, and life science projects. Core technical capabilities include cGMP-compliant HVAC design for FDA-regulated pharmaceutical and biotech facilities (FDA 21 CFR Part 211, ISO 14644-1), data center cooling engineering (ASHRAE 90.4-2025 MLC, Uptime Institute Tier redundancy), industrial ventilation, paint booth installation engineering with AQMD compliance, and steam boiler plant design, supported by commissioning, energy/sustainability engineering, facility assessment, and construction phase support. The firm holds engineering licensure across five western U.S. states—California, Washington, Arizona, Nevada, and Utah—and maintains active memberships in ASHRAE, ASPE, NFPA, ISPE, the Building Commissioning Association, USGBC, IAPMO, ICBO, ASME, and NSPE.

The firm operates as a B2B engineering consultancy with an enterprise field sales motion, acquiring projects through direct engagement with building owners, architects, and general contractors, supplemented by referrals and inbound inquiries from content marketing (technical blog, LinkedIn, and other social channels). Revenue is generated on a project-fee basis, with pricing tailored to scope, building type, regulatory complexity, and service deliverables from design through construction closeout. APEC reports 609 completed projects across 106 customers, including marquee enterprise engagements (Johnson & Johnson, Disney Facility Services, Edwards Lifesciences, Varian, Neutrogena, Olam Spices, Gensler) and public-sector work (City of Corona, Antelope Valley Hospital, Long Beach Unified School District). Distribution is direct with no intermediaries, resellers, or marketplace platforms. The firm is independently owned with no identified parent company, institutional investors, or PE/VC backing, and reports 1–10 employees based on open engineering and CAD positions.
