What PremiStar does
PremiStar is a commercial mechanical services platform providing HVAC, plumbing, building automation and controls, sheet metal, piping, refrigeration, and design-build services to commercial, industrial, institutional, healthcare, education, municipal, and government customers. The company operates 62 branch locations across 19 states with 3,100+ employees (including 2,350 field service technicians), 24/7 emergency response, and over 5,500 preventive maintenance contracts covering an installed base of 16,000 customers. Service is delivered directly through regional branch teams led by Regional Presidents (North and South) and supported by an SVP of Commercial Development focused on organic growth and pricing, plus a VP of M&A (Bill Tamul) running a dedicated acquisitions program targeting owner-operated HVAC, plumbing, and building controls companies with $10M-$100M in annual revenues.
The business generates revenue across four streams: (1) recurring service and maintenance contracts (preventive maintenance plus emergency repair), (2) installation and design-build project revenue, (3) parts and equipment replacement, and (4) building automation/controls work. Pricing is custom-quoted per engagement with multi-year service agreements; specific rates and contract values are not publicly disclosed. Founded in 1930 as Reedy Industries and rebranded as PremiStar in July 2022, the company is owned by Partners Group (a $185B AUM private markets firm that took the primary sponsor role in 2021, succeeding Audax Private Equity). Under CEO Joe Kirmser, who joined in 2019, the company has executed 40+ acquisitions and reported 6x+ revenue and EBITDA growth through June 2026. Field technicians are equipped with XOi Technologies' AI- and AR-driven tools; acquired regional brands are largely retained post-close.
