MICHAEL KOST

Michael Kost specializes in the installation, repair, and maintenance of critical HVAC, plumbing, and building systems for federal facilities, with deep expertise in air handling units, steam and refrigeration systems, exhaust ventilation, and fan coil replacements. The contractor delivers precision mechanical services on mission-critical infrastructure, including boiler line repairs, blower motor replacements, steam coil upgrades, and rooftop exhaust fan installations—often under tight operational constraints in active healthcare and correctional environments. Their technical proficiency spans both preventive maintenance and full system overhauls, with demonstrated ability to execute complex retrofits within occupied buildings while maintaining environmental and safety compliance. A key differentiator is their consistent delivery of high-stakes mechanical repairs in sensitive VA and DOJ facilities, where downtime is not an option. The contractor maintains a strong, recurring relationship with the Department of Veterans Affairs, performing routine and emergency HVAC interventions across multiple VA medical centers, including roof-mounted system upgrades and abandoned equipment removal. They also deliver similar mechanical services for the Department of Justice, particularly in correctional facilities, and have completed one project for the Department of Transportation involving steam line integrity restoration. These engagements reflect a pattern of trusted, repeat work in mission-critical federal infrastructure. Michael Kost operates primarily under NAICS 238220, focusing on plumbing, heating, and air-conditioning contracting, with complementary work in commercial and institutional construction under NAICS 236220. This positions them as a specialized mechanical systems contractor serving federal institutional clients, particularly in healthcare and justice sectors where HVAC reliability directly impacts public health and operational continuity. As a Service-Disabled Veteran-Owned Business based in the Bronx, NY, the contractor leverages its small business structure and federal certification to compete effectively in targeted government procurement markets. Their localized presence enables rapid response and sustained support for Northeastern federal facilities.
