What Prime Specialty Contracting does
Prime Specialty Contracting is a full-service mechanical contractor headquartered in Marquette, Michigan, with a secondary office in Escanaba, serving residential, commercial, and industrial clients across Michigan's Upper Peninsula. Founded in 2019 by Cory Bushong, the company operates four integrated service lines: commercial and residential HVAC (system design, installation, ductwork, rooftop units, heat pumps, preventative maintenance); plumbing and pipefitting (including medical gas, sanitary, and high-purity piping); process piping and mechanical systems (brewery steam and chilled water, utility piping, turnkey design through commissioning); and custom metal fabrication (in-house shop with CAD design and MIG/TIG/Stick welding for ductwork, exhaust, architectural metal, and enclosures).
The business runs on a project-based, professional-services revenue model, with quotes provided per engagement for installations, service calls, and maintenance contracts. All revenue is generated through direct field sales — licensed technicians and project managers dispatched to customer sites — with no resellers or intermediaries. The customer base spans three primary segments (homeowners, commercial facilities, and industrial operators) plus general contractors as a secondary channel. Approximately 90 employees support operations across the two offices. Pricing is quote-based and not publicly disclosed.
The company was acquired by Tweet Garot Mechanical, a Wisconsin-based mechanical contractor, in February-March 2026, with founder Cory Bushong retained and both locations continuing to operate under the Prime brand. No AI/ML capabilities, software products, or external integrations are part of the operating model; the differentiation rests on in-house fabrication, licensed trade credentials (including medical gas), and regional density across the Upper Peninsula.
