ProAir

What ProAir does

Pro-Air Mechanical Contracting (doing business as ProAir) is a private, employee-owned mechanical contractor serving healthcare, data center, education, and life sciences end markets primarily within the Baltimore-Washington corridor. The company's core offering is comprehensive mechanical contracting services encompassing the design, fabrication, and installation of mechanical systems, supported by in-house Building Information Modeling (BIM) operations. Its operations are anchored by a recently consolidated 186,878-square-foot fabrication and BIM facility at 350 Winmeyer Ave. in Odenton, Maryland, part of a portfolio of approximately 258,000 square feet. The company positions itself for complex, regulated, and mission-critical facility work, where pre-fabrication, BIM coordination, and specialty mechanical expertise are required.

The company began operations in 2001 from a 6,500-square-foot space and has grown its footprint roughly 40-fold over the subsequent 25 years, an indicator of sustained organic expansion funded through operations and a $15 million credit facility from Crystal Financial in October 2017. There is no external private equity, strategic parent, or public market affiliation disclosed; ownership rests with employees, with Chad Mayes identified as owner/CEO. The business model is project-based mechanical contracting, with revenue generation tied to commercial and industrial construction and maintenance contracts rather than subscription or recurring software revenue. Pricing is not publicly disclosed and the company does not maintain a public app, API, or software product surface.

Pro-Air's customer segmentation is vertical-oriented rather than size-oriented, with healthcare and data center verticals described as primary alongside education and life sciences. The company maintains a long-standing 25-year partnership with commercial real estate broker KLNB, which has supported its real estate and expansion strategy, including the recent Odenton consolidation that involved the early termination of two prior industrial leases with Prologis. The company is actively expanding operations as of the April 2026 announcement and is described in source material as one of the nation's largest employee-owned mechanical contractors.

Broad incumbents

• APi Group: Diversified safety, specialty, and industrial services holding with mechanical contracting exposure through legacy API Mechanical. Comparable in serving regulated, mission-critical facilities at larger scale.
• Comfort Systems USA: Leading national HVAC and mechanical services provider serving commercial, industrial, and institutional customers. Closely comparable in core mechanical contracting scope, with national scale ProAir does not have.
• EMCOR Group: Largest publicly traded mechanical and electrical contractor in the U.S. with a broad portfolio across commercial, industrial, healthcare, and data center clients. Directly comparable end markets and service lines to ProAir, but operates nationally and is far larger.

Emerging players

• CMTA: Engineering-led mechanical design and commissioning firm with a strong healthcare, K-12, and higher education portfolio. Adjacent rather than head-to-head, but highly comparable in customer focus and project types.

Direct peers

• Limbach Holdings: Specialty mechanical contractor focused on healthcare, life sciences, data centers, and higher education — nearly identical vertical mix to ProAir. Closest publicly traded peer in both customer mix and project type.
• Murphy Company: Employee-owned mechanical contractor with a similar focus on healthcare, higher education, and mission-critical facilities. Closely comparable in ownership culture and project profile.
• IES Holdings: Electrical and mechanical services provider operating across commercial, industrial, and data center end markets. Comparable in scope of mechanical services and customer types, though larger and publicly traded.
• TDIndustries: Employee-owned mechanical contractor serving commercial, healthcare, and higher education clients in Texas and the Southwest. Highly comparable ownership structure and service model to ProAir's employee-owned model.
• Southland Industries: Large mechanical contractor with in-house fabrication and design-build capabilities serving healthcare, data center, and higher education clients. Directly comparable fabrication-driven delivery model.

Regional players

• HB Mechanical: Regional mechanical contractor with similar mid-Atlantic and Southeast exposure, serving healthcare, education, and commercial clients. Comparable service mix and scale, but operates in adjacent rather than overlapping geography.
