What Action Air Systems does
Action Air Systems, Inc., founded in 1987 and headquartered in Manchester, Connecticut, is a full-service mechanical contractor providing commercial and industrial HVAC/R, plumbing and piping, and custom sheet metal fabrication services across Southern New England (Connecticut, Western Massachusetts, and Rhode Island). The company operates from a 20,000-square-foot facility that includes an in-house sheet metal fabrication shop capable of working in stainless steel, carbon steel, aluminum, iron, spiral duct, and FRP, plus warehouses, offices, and a training room; it holds CT, RI, and CT MCO mechanical licenses.
Its offerings span design/build mechanical system installation (with single-source responsibility for electrical, welding, insulation, and drawings), preventative maintenance service agreements, 24/7 emergency repair, and specialty systems including Variable Refrigerant Flow (VRF), commercial heat pumps, zone control, precision cooling for IT facilities/data centers, commercial refrigeration, and Healthy Air Solutions (UV lights, bipolar ionization, UVC, MERV 13+ filtration). Core technology is conventional commercial/industrial HVAC, plumbing, and sheet metal rather than proprietary software or controls platforms.
The company monetizes through a mix of project-based design/build installation revenue, recurring preventative maintenance service agreements (annual billing, custom-priced), 24/7 emergency repair (professional services), and sheet metal fabrication work that supports both in-house installs and potential third-party customers. Go-to-market is direct enterprise field sales targeting government, healthcare, education, commercial real estate, manufacturing, cannabis, and data center customers; acquisition channels include website-driven service requests and a documented customer base anchored by names such as St. Francis Hospital, University of Connecticut, Fandotech, Town of East Hampton, Forest Street Cultivation, and Jordan Furniture. Since August 2025, Action Air has operated as a portfolio company of NexCore, a commercial HVAC platform backed by Trinity Hunt Partners, and in June 2026 it acquired Air Comfort Systems of Wallingford to expand its southern Connecticut footprint and recurring contract base.
