About the company
Tolin Mechanical Systems Company, LLC (Tolin Mechanical Systems CO. Division, operating as Honeywell Authorized Dealer) provides HVAC, refrigeration, and mechanical systems installation, maintenance, repair, and emergency response services to civilian federal agencies as a prime contractor (96% of recent awards), competing full-and-open with no SBA set-aside certifications. The company is a for-profit limited liability company and subsidiary of Mshc, Inc. (doing business as Service Logic), headquartered in Denver, Colorado, with geographic concentration in the Rocky Mountain region and service delivery across seventeen distinct federal agencies. Primary NAICS classification is 238220 (Plumbing, Heating, and Air-Conditioning Contractors), with secondary work classified under 811310 (Commercial and Industrial Machinery and Equipment Repair and Maintenance) and 332999 (All Other Miscellaneous Machinery Manufacturing).
Customer concentration centers on interior and science infrastructure agencies. The U.S. Geological Survey's Office of Acquisitions and Grants accounts for ten awards valued at $1.8 million combined potential value (19% of total), followed by the Indian Health Service (four awards, $1.2 million) and the Bureau of Reclamation (four awards, $114 thousand). The GSA Federal Acquisition Service dominates potential value through a single Multiple Award Schedule contract — the company's primary vehicle — valued at $5.8 million with a June 2029 completion date. That GSA MAS contract (Special Item Number 561210FAC, awarded June 13, 2024) carries HVAC Technician labor at $157.98 per hour (high school education, one year of experience, no clearance required) and extends overtime and premium rates to $315.97 per hour. Within its GSA Schedule seat, Tolin Mechanical is available for ordering by all federal agencies.
Representative prime work spans specialized refrigeration support and facilities maintenance. The company holds a $351,389 purchase order from USGS on behalf of the National Science Foundation (awarded October 1, 2026, ultimate completion September 30, 2028) for operations and maintenance of a newly constructed CO2 refrigeration plant at the NSF Ice Core Facility in Denver, requiring 99.9% system uptime and 24/7/365 operation. Earlier, Tolin Mechanical delivered a $474,085 time-and-materials purchase order from USGS (awarded December 1, 2021, extended through November 30, 2026) for maintenance of the same freezer building and refrigeration systems, including preventative maintenance, emergency repairs, compressor rebuilds, and quarterly control-system inspections. The Indian Health Service has issued multiple emergency and rental awards totaling over $1.2 million, including a $526,597 HVAC chiller rental agreement at Parker, Arizona (awarded July 8, 2025, through November 30, 2026), a $238,578 emergency chiller repair at the Colorado River Service Unit (awarded July 9, 2024), and a $163,520 chiller rental and repair contract in Phoenix (awarded August 24, 2023). The Bureau of Reclamation awarded a $17,944 definitive contract (July 6, 2026) for monthly and quarterly HVAC preventative and corrective maintenance at the Leadville Water Treatment Plant, with Service Contract Labor Standards applying under Colorado Wage Determination 2015-5439 and corrective maintenance capped at $10,000 per year.
Activity has remained steady at two to three awards per year over the past five years (2021–2026), with three awards reaching ultimate completion in the next twenty-four months (combined potential value $1.4 million), representing recompete risk. Tolin Mechanical operates almost entirely as a prime (96% of recent awards); two named subcontract engagements under Asrc Federal Facilities Logistics LLC in 2024–2025 involved humidifier installation and HVAC system replacement task orders. Service Contract Inventory data captures minimal activity — seven SCI records (five as prime, two as sub) across FY2022–FY2025 — reflecting the company's emphasis on purchase orders and equipment rentals rather than labor-intensive service contracts above the $150,000 reporting threshold. SCI records show roughly 3.1 FTEs and 2.8 FTEs delivered to federal customers in FY2024 and FY2025 respectively, with no average subcontractor hour share on prime contracts, indicating direct delivery by company personnel.
