What Kool Acquisition, LLC does

Kool Acquisition, LLC, doing business as KSW Mechanical LLC, is a New York City-based specialty mechanical contractor founded in 1984 that designs, installs, and maintains heating, ventilation, and air conditioning (HVAC) systems and process piping for large-scale commercial and residential buildings. The firm serves general contractors, developers, construction managers, and building owners through four delivery models: Conventional Bid/Build, Value-Engineering, Design/Build, and proprietary Trade Management, with the latter focused on subcontractor vetting and cost-efficient coordination. Visible project credentials include 50 Hudson Yards, Mt. Sinai South Nassau, Delta Airlines at LaGuardia, and Archer Towers, alongside relationships with tier-one counterparties such as Suffolk Construction, Related Companies, AECOM, Tishman Speyer, Skanska, Vornado, and Greystar. KSW operates from a single headquarters in Long Island City, NY, and is surrounded by affiliated entities — Orion Technical Services, TEC Building Systems, and Precision Solar Renewables — that extend the offering into technical services, building systems, and renewable energy for the same NYC client base. Revenue is generated through project-based construction contracts with one-time, quote-based pricing tied to building specifications, and the go-to-market motion is direct enterprise field sales into the NYC construction ecosystem.
