The company provides independent testing, adjusting, balancing, commissioning, certification, and cleanroom validation services for HVAC systems, building environments, and controlled-environment facilities. Its portfolio spans four core service lines: Test & Balance Services (air system balance, hydronic balance, fume hood calibration, biosafety cabinet certification, sound and duct leakage testing, laminar flow hoods, and health department approval), Specialized Services (compressed air testing and viable/nonviable air sampling), Cleanroom Services (cleanroom certification, calibration and testing, HEPA leak testing), and Commissioning Services (general, LEED certification, new construction, and retro commissioning). The firm's technical foundation is grounded in NEBB-certified procedures, NSF International accreditation for biosafety cabinetry, and compliance with ISO Standards, IEST Recommended Practices, cGMP, USP-797, and NSF/ANSI 49.

MTS serves a diverse mix of enterprise clients across healthcare, pharmaceutical manufacturing, life sciences, biotechnology, manufacturing, data centers, commercial real estate, education, and government sectors, ranging from Fortune 500 companies to small private enterprises. The firm operates a sales-led go-to-market with project-based quote pricing and multi-year contracts; it has completed projects across the United States and internationally in Canada, Mexico, Costa Rica, and Malaysia. Documented outcomes include 5+ million square feet of commissioned space representing nearly $1 billion in capital investments, and energy savings claims of 5-20% for customers through proper testing, balancing, and commissioning.

The company employs 6 people and is structured as a founder/management-owned Michigan corporation with no disclosed parent company, no private equity backing, and no venture capital investment. Revenue is not publicly disclosed. The team holds NEBB certifications across multiple disciplines, and the firm maintains active memberships in ASHRAE, IEST, CETA, and ACCA. Customer acquisition relies primarily on direct sales through website quote and consultation requests, with professional certifications serving as the primary credibility signal.

Broad incumbents

• Stantec: Global engineering consultancy with a building commissioning practice serving healthcare, pharmaceutical, and life sciences clients; competes on large institutional projects where MTS may be subcontracted.
• TRC Companies: Large U.S. engineering and consulting firm with a building sciences practice covering commissioning, TAB, and cleanroom testing for commercial and industrial clients — much broader portfolio but overlapping core services and customer segments.
• WSP: Global professional services firm with building commissioning, TAB, and cleanroom-related services in its property and buildings practice; a large incumbent competing for the same regulated buyer pool.
• Burns & McDonnell: Employee-owned engineering firm with commissioning, TAB, and facilities services serving healthcare, mission critical, and industrial clients across North America.
• Haley & Aldrich: Environmental and geotechnical engineering firm with a building sciences group offering commissioning and HVAC assessment services to similar regulated facility owners.
• Affiliated Engineers: Engineering firm with a dedicated commissioning and TAB group serving healthcare, higher education, and science & technology clients; competes for the same high-spec MEP and cleanroom engagements MTS targets.

Emerging players

• Aircuity: Technology company providing continuous air quality and cleanroom monitoring solutions; not a direct TAB competitor but increasingly overlaps with traditional certification work as facilities shift to IoT-based monitoring.

Direct peers

• Pure Air Control Services: Florida-based NEBB-certified independent firm providing HVAC testing & balancing, cleanroom certification, and biological safety cabinet testing — directly overlapping MTS's service portfolio and customer base across healthcare, pharmaceutical, and industrial facilities.
