What Feyen Zylstra does

Feyen Zylstra is a Grand Rapids, Michigan-based electrical contracting and industrial technology firm founded in 1980 by Bob Zylstra and Marlin Feyen. It provides comprehensive electrical design, construction, low-voltage, automation, and maintenance services to manufacturing, commercial, healthcare, data center, government, food & beverage, and life sciences customers across Michigan, the Carolinas, and Tennessee. The company is now a subsidiary of Comfort Systems USA (NYSE: FIX) following a Q4 2025 acquisition.

The company's service portfolio spans three integrated pillars: (1) Design Engineering — Design Build/Design Assist, BIM/VDC with LOD 100–500 modeling, Scan-to-BIM laser scanning, and off-site prefabrication delivered just-in-time; (2) Electrical Construction — power distribution, low/medium voltage systems, structured cabling and fiber optics, fire alarm and access control, AV integration, outdoor duct bank and medium-voltage terminations, and custom control panel build; (3) Specialized Technical Services — PLC/HMI automation, industrial networking and safety integration, planned shutdowns, generators and emergency power, and preventative maintenance including infrared thermography, arc flash studies, and transformer oil analysis. Software/tooling centers on BIM/VDC platforms and laser scanning rather than proprietary AI/ML.

Feyen Zylstra generates revenue through project-based electrical construction contracts, recurring preventative maintenance agreements, embedded onsite support, 24-hour emergency service, and design/engineering fees, sold via direct field sales through account managers and business development teams. Pricing is project-specific and not publicly disclosed. Primary customers include MidMichigan Health, Vanderbilt University, Four Seasons Hotel Nashville, McLaren Hospital, Bradford White, City of Walker, Barton Malow, Christman Co., Kajima Building & Design Group, Interlochen Center for the Arts, and General Mills / Yoplait, with typical deal sizes ranging from maintenance retainers to multi-million-dollar tenant build-outs and industrial installations.

Core offering

Feyen Zylstra provides turnkey electrical contracting and industrial technology solutions for commercial, industrial, and healthcare facilities. Services span design engineering (design-build, design-assist, BIM/VDC, Scan-to-BIM, prefabrication), electrical construction (power distribution, low/medium-voltage systems), systems integration (fire alarm, access control, structured cabling, AV), automation & controls (PLC, HMI, robotics), and ongoing preventative maintenance and emergency power services. Customers engage through a single point of contact across project delivery and recurring service contracts.

Product overview

Feyen Zylstra is an electrical services and industrial technology firm that operates as a single unified service portfolio rather than a platform-plus-modules architecture. The company provides comprehensive, turnkey electrical solutions organized around three core pillars: Design Engineering (encompassing Design Build, Design Assist, BIM/Virtual Design & Construction, Prefabrication, and Scan-to-BIM), Electrical Construction (covering Electrical Construction, Electrical Services, Systems Solutions, Low Voltage Solutions, Outdoor Solutions, and Panel Build), and Specialized Technical Services (including Automation & Controls, Audio Visual Solutions, Planned Shutdowns, Generators & Emergency Power, Preventative Maintenance, and Power Studies). Customers access these capabilities through a single point of contact, with services ranging from initial design through construction, ongoing maintenance, and emergency support across industrial, commercial, healthcare, and data center markets.
