What Mechanical Service Inc. does

Mechanical Service of Galesburg, Inc. (dba MSI; "Rely on MSI") is a privately held, family-owned mechanical contracting company incorporated in 1972 as a joint venture between Stinger Plumbing & Heating, Inc. and John R. Holt, Inc. The Benedict family controls the firm, with Rob Benedict as CEO and Owner, Trent Benedict as President, Blake Benedict as COO, and Adam Benedict as Vice President. The company provides HVAC/R, plumbing, electrical, process piping, and custom sheet metal fabrication services to residential, commercial, industrial, healthcare, institutional, and public-utility customers across the Galesburg and Peoria, Illinois region. Service delivery is performed by qualified union technicians sourced through six signatory locals (IBEW Local 34, Plumbers & Pipefitters Local 25, Plumbers Local 63, Steamfitters Local 353, Sheet Metal Workers Locals 1 and 91), with claimed combined technician experience of nearly 350 years.

MSI operates two physical locations: a headquarters at 1144 Monmouth Boulevard in Galesburg, IL, and a second office at 9909 W. Primrose Lane in Edwards (greater Peoria), IL. Both locations house process piping fabrication shops; the Peoria site additionally includes a sheet metal fabrication shop acquired via the 2013 purchase of Du-Mont Company. Fabrication equipment includes 6'x12' and 6'x20' Hi-Def plasma tables, a 1/2" x 10' Wysong shear, a 1/4" x 12' press brake, MIG/TIG and spot welding, and a Vicon coil line. The company supports 24-hour emergency plumbing and HVAC response and offers design, engineering, fabrication, contract administration, and on-site supervision as a bundled package.

The business model combines one-time installation contracts (new construction, remodels, design-build), ongoing repair and maintenance, and custom sheet metal fabrication. Pricing is quote-based, delivered through phone requests and online estimate forms across residential, commercial, and industrial service tiers. Distribution is direct via union field technicians with no digital self-service platform. Customer concentration is anchored in regional healthcare systems (Graham Health System, Methodist Medical Center of Illinois, OSF St. Mary's) and educational institutions (Knox College, Knoxville High School, Lombard Middle School, R.O.W.V.A. Grade School), with supplementary commercial/industrial and residential accounts. Channel partners include Ameren Illinois ActonEnergy Programs (utility energy-efficiency incentives) and American Standard Heating & Air Conditioning (Customer Care dealer). Revenue is not publicly disclosed; the 32-employee headcount and multi-million-dollar healthcare project wins imply an estimated annual revenue band of $10M-$25M, with limited visibility.
