AGC

What AGC does

AGC Inc. is a privately held Bay Area mechanical contracting firm founded in 2000 by four principals — Randy Attaway, Beth Guinnane, Tony Volpi, and Jon Mohs — and headquartered in Campbell, California. The company provides HVAC, process piping, plumbing, project management, and engineering services for commercial and institutional facilities, with a particular specialization in highly regulated environments including cleanrooms, OSHPD-compliant healthcare facilities, FDA-validated pharmaceutical and biotech manufacturing, and specialized research laboratories. AGC employs BIM-based 3D coordination, a design-build and design-assist delivery model, LEED documentation capabilities, and a proprietary JHACO compliance testing program developed for hospital fire/smoke damper maintenance. The firm's customer base spans Stanford University, Kaiser, San Jose State University, Genentech, KLA, NASA, Lucid, Roche, Nokia, Lumentum, First Solar, and other Bay Area institutions across higher education, healthcare, biotech, semiconductor, and clean-technology verticals.

Revenue is generated entirely through project-based contracts (fixed-price or cost-plus) with no recurring component; pricing is custom and quote-based, never publicly disclosed. Go-to-market is sales-led and relationship-driven, relying on direct engagement with enterprise owners, partnerships with general contractors such as Blach Construction and Devcon Construction, word-of-mouth referrals, and competitive bidding on RFPs within the Bay Area. The company operates as a unified service provider across its five service lines rather than as a modular platform, delivering turnkey mechanical systems from conceptual design through commissioning. Marketing is almost entirely offline — no digital storefront, no self-serve channels, and no public digital marketing presence — reflecting the trust-based, reputation-driven nature of specialized mechanical contracting work.

As of 2025, AGC is actively hiring across trades and professional roles (plumbers, pipefitters, sheet metal workers, HVAC technicians, project managers, estimators, design engineers, BIM/CAD specialists) and has explicitly stated it is expanding in the private sector. Recent project manager hires in 2023-2025 and the addition of dedicated preconstruction leadership suggest organizational scaling beyond the original founder-led structure, though the firm remains geographically concentrated in the San Francisco Bay Area with no disclosed expansion plans beyond Northern California.

Direct peers

• TDIndustries: TDIndustries is an employee-owned mechanical contractor providing HVAC, plumbing, and process piping services to commercial, healthcare, education, and high-tech customers. It is comparable to AGC in service mix, end-market specialization, and design-build delivery approach, but is a larger multi-regional firm.
• Limbach Holdings: Limbach is a publicly traded national MEP services firm specializing in complex mechanical, plumbing, and electrical systems for institutional and commercial clients. It is directly comparable to AGC in scope of services (HVAC, plumbing, process piping) and customer profile (healthcare, higher education, life sciences), but operates at much larger scale and across multiple geographies.
• Murphy Company: Murphy Company is a regional mechanical contractor providing HVAC, plumbing, process piping, and engineering services to commercial, healthcare, and institutional clients. It is closely comparable to AGC in service portfolio and end-market focus but operates primarily in the Midwest rather than the West Coast.
• Southland Industries: Southland Industries is a large national MEP design-build firm providing HVAC, plumbing, process piping, and building automation across commercial, industrial, healthcare, and institutional markets. It directly competes with AGC in design-build delivery for complex institutional and life sciences projects, but operates with broader self-perform capabilities and a national footprint.
• HB Mechanical Group: HB Mechanical Group is a commercial HVAC and plumbing contractor serving healthcare, education, and life sciences customers in the Western US. It is comparable to AGC in trade focus and regulated-environment specialization, though generally smaller in scale and with a less prominent cleanroom/FDA-validation positioning.

It is directly comparable to AGC in service offering and end-market focus but operates at significantly larger scale across multiple US geographies.

Broad incumbents

• APi Group: APi Group is a global provider of safety, specialty, and industrial services with a significant mechanical contracting and building services segment. It is a broad incumbent serving similar end markets as AGC (healthcare, education, commercial) but with a much wider service portfolio and geographic footprint.
• Comfort Systems USA: Comfort Systems USA is a leading national provider of mechanical services including HVAC, plumbing, and process piping for commercial and industrial customers. It competes with AGC in the same core trade categories but operates through a federation of subsidiaries across the country, giving it broader geographic and segment reach.
• EMCOR Group: EMCOR is the largest publicly traded mechanical and electrical contractor in the US, offering HVAC, plumbing, process systems, and building services across commercial, industrial, healthcare, and institutional markets. It overlaps directly with AGC's core mechanical contracting services but operates at vastly greater scale with national reach and a significant recurring service revenue stream.

Regional players

• S.M. Lawrence Company: S.M. Lawrence is a mechanical contractor providing HVAC, plumbing, and process piping for industrial, healthcare, and institutional clients in the Southeast US. It is comparable to AGC in service scope and customer profile but serves a different geography, making it a regional rather than direct competitor.
