What S&Z Sheetmetal does

S&Z Sheetmetal, Inc. is a privately held commercial and industrial HVAC and sheet metal contractor headquartered in Flint, Michigan, founded in 2001. The company delivers integrated HVAC installation, replacement, repair, and maintenance services alongside custom sheet metal fabrication in steel, stainless steel, and aluminum for hospitals, universities, schools, industrial complexes, museums, sports venues, and office buildings. Its primary customers are general contractors, construction managers, and property owners in Michigan, with a documented project portfolio spanning the University of Michigan (including a 15-MW Central Power Plant turbine addition), Oakland University, Auto-Owners Insurance, the Sloan Museum, the Schoolcraft Elite Sports Complex, and an upcoming Ford Motor Company bid in Dearborn.

The company's technology stack is built around Building Information Modeling (BIM) and Computer Aided Design (CAD), with over 20 years of in-house experience applied to pre-construction visualization, clash detection, and coordination with architects, engineers, and MEP trades. BIM/CAD models feed directly into in-house metal fabrication for custom ductwork, air handling units (AHUs), rooftop units (RTUs), VAV boxes, and mechanical louvers. Notable project scopes include 23,500 linear feet of ductwork on a 236,000 sqft office building and 7,000 linear feet of ductwork on a museum renovation, demonstrating capacity for large-scale mechanical installations.

S&Z operates a project-bidding business model, winning work through competitive tenders and repeat engagements with general contractors. Revenue is generated on a project-by-project, quote-based basis across three service streams: HVAC installation services, custom sheet metal fabrication, and BIM/CAD design services. The company markets primarily through its corporate website and direct relationships, with no public pricing, no subscription or recurring revenue model, and no disclosed funding or external investors. Ownership appears to be founder/operator-led, consistent with a small privately held specialty contractor of 11-50 employees operating regionally within Michigan.

Core offering

S&Z Sheetmetal designs, fabricates, and installs commercial and industrial HVAC systems and custom sheet metal products, including ductwork, air handling units, and architectural sheet metal assemblies. The company operates an in-house fabrication shop in Flint, Michigan, and supports projects with BIM and CAD design services from concept through installation.

Product overview

S&Z Sheetmetal is a commercial and industrial sheet metal contractor offering an integrated suite of services centered on HVAC systems, sheet metal fabrication, BIM (Building Information Modeling), and CAD (Computer Aided Design). Their core portfolio consists of five interconnected service lines: HVAC Services (installation, replacement, repair, and maintenance of heating and cooling systems), Sheet Metal Services (metal panel siding, flashing, custom ductwork), BIM Services (3D building modeling for design collaboration and pre-construction visualization), CAD Services (AutoCAD-based 2D drawings and 3D model creation for manufacturing), and Metal Fabrication (custom fabrication in steel, stainless steel, and aluminum). Projects combine these capabilities — for example, BIM is used to plan ductwork layouts that are then fabricated and installed as part of HVAC systems for hospitals, universities, and commercial buildings.

Direct peers

• J.F. Ahern: Midwest mechanical contractor serving industrial, commercial, and institutional customers with HVAC, plumbing, and specialty services. Comparable in regional mechanical contracting focus and institutional customer mix to S&Z.
• Limbach Holdings: Public commercial mechanical contractor specializing in HVAC, plumbing, and specialty piping for institutional and industrial customers. Comparable in that it serves the same end markets (healthcare, higher ed, commercial) via a project-based bid model similar to S&Z's.
• John E. Green Company: Regional Michigan-based mechanical contractor providing HVAC, plumbing, and process piping to commercial and industrial customers. Highly comparable in geography, customer base, and project-based service model to S&Z.

Broad incumbents

• APi Group: Diversified safety, specialty, and industrial services company with significant HVAC and mechanical contracting exposure. Comparable in core mechanical services but much larger and more diversified across multiple service lines.
• MYR Group: Specialty contractor in electrical construction and mechanical services for commercial, industrial, and utility markets. Comparable in specialty contracting business model and institutional customer exposure, with adjacent mechanical/HVAC overlap.
• EMCOR Group: Major mechanical and electrical construction services firm serving commercial, industrial, and utility markets. Overlap with S&Z's HVAC and sheet metal installation work, but EMCOR operates nationally with far greater scale and resources.
• Johnson Controls International: Global provider of HVAC equipment, controls, and building services. Comparable in HVAC and building systems focus, but operates as a much larger OEM plus services platform that competes with S&Z primarily at the equipment and controls layer.
• Comfort Systems USA: Large national mechanical contractor focused on HVAC installation, service, and piping. Overlaps directly with S&Z's HVAC and sheet metal scope but operates at significantly greater scale and geographic diversification.

Regional players

• Feyen Zylstra: Michigan-based specialty contractor providing electrical and technology services to commercial and industrial customers. Comparable as a Michigan-rooted specialty contractor of similar size and customer base, though focused primarily on electrical rather than sheet metal/HVAC.
• Lee Company: Tennessee-based mechanical contractor providing HVAC, plumbing, and electrical services for commercial and industrial customers. Comparable in service offerings and project-based commercial contracting model, though operating in a different regional market.
