Mollenberg-Betz

What Mollenberg-Betz does

Mollenberg-Betz Inc. is a privately held, third-generation, family-owned mechanical contracting firm headquartered at 300 Scott Street in Buffalo, New York. Founded in 1910 by Henry J. Mollenberg and Jacob Betz, the company has built a 115-year operating history in Western New York and adjacent regions, beginning with general machining work, pivoting into industrial refrigeration after a 1911 system for Citizens' Dairy of Lockport, installing Buffalo's first air conditioning system at Sattler's Department Store in 1937, and progressively adding HVAC, process piping, plumbing, boiler service, sheet metal, controls, and fabrication capabilities through both organic buildout (1960 divisional restructuring, 1985 fabrication facility) and acquisitions (Cayuga Piping in 1998; Custom Sheet Metal and Custom Metal Fabrication in 2010).

The company's service portfolio spans design, fabrication, installation, commissioning, and 24/7/365 service across HVAC, ammonia/Freon/cryogenic refrigeration, plumbing, process piping, boiler systems, sheet metal, and controls. Underlying these services is a vertically integrated operating platform: an 18,000 sq. ft. fabrication facility with ASME Section IX-qualified welders performing orbital welding, mechanical manipulator welding, and pressure testing to 10,000 PSI; a panel shop producing 120V–4160V control panels to Class 1 Division 1 explosion-proof standards; a parts distribution division stocking OEM and aftermarket components for Frick, York, Vilter, Evapco, Mycom, Hansen, Sporlan, Johnson Controls, Honeywell, and others; and an in-house 3-D CAD/BIM design group. The firm holds the only OSHA Voluntary Protection Programs (VPP) approval issued to a mechanical contractor in New York State.

Mollenberg-Betz generates revenue through three primary streams: project-based mechanical contracting work (design, fabrication, installation, commissioning) sold through direct enterprise field sales; recurring service and maintenance contracts, including emergency response, delivered through service branches in Buffalo, Rochester, Syracuse, and Western Pennsylvania staffed by 30+ full-time technicians; and hardware parts sales to its own installed base, peer contractors, and international customers. Customers are commercial, industrial, and institutional clients in food and dairy processing, pharmaceutical, chemical, petrochemical, automotive, power generation, ice rink, and clean-room environments. Pricing is quote-based and project-specific; revenue is not publicly disclosed. The business is led by H. Van Mollenberg as President-CEO (third generation) and represents roughly 101–250 employees, with 75–150 construction workers supplemented by an interdisciplinary engineering, estimating, CAD, and support team.

Core offering

Mollenberg-Betz is a mechanical contracting firm that designs, fabricates, installs, commissions, and services HVAC, refrigeration (ammonia, Freon, cryogenic), plumbing, process piping, and boiler systems for commercial, industrial, and institutional customers. The company operates an 18,000 sq. ft. pre-fabrication facility, a control panel shop, and a sheet metal shop, supported by a 24/7 service division and a parts distribution operation across Western New York, Rochester, Syracuse, and Western Pennsylvania.

Product overview

Mollenberg-Betz is a century-old mechanical contracting firm (established 1910) offering a portfolio of interrelated service lines rather than a single software product. Its core offerings center on refrigeration (ammonia, Freon, and cryogenic systems), HVAC, plumbing, process piping, and boiler services, delivered through specialized internal divisions. The portfolio is unified by shared engineering and fabrication capabilities: a pre-fabrication shop (18,000 sq. ft.) that produces piping spools, skid packages, and pressure vessels serving multiple service lines; a panel shop that fabricates control and PLC panels used across refrigeration, HVAC, and process systems; and a sheet metal shop for ductwork and custom fabrication. The parts division supports all service lines with a managed inventory of original equipment and replacement parts. The 24/7 service and maintenance division serves as the ongoing customer engagement layer across all offerings, providing troubleshooting, preventive maintenance, and emergency response. Subsidiaries include MB Welding and Fabricating (25 Depot Street, Buffalo) and Custom Sheet Metal (303 Central Avenue, Buffalo).
