National Standby Repair

What National Standby Repair does

National Standby Repair Inc. is a family-owned and veteran-owned standby generator services company founded in 1981 by Ken Thompson in Croton-On-Hudson, New York. The company sells, installs, repairs, maintains, and rents standby generators for residential and commercial customers across the Tri-State area of New York, New Jersey, and Connecticut, operating from two office locations and providing 24/7 emergency dispatch. It is a factory-authorized dealer and service provider for five major generator brands — Kohler (Platinum tier), Generac, Cummins, Briggs & Stratton, and Winco — and additionally services legacy Onan units, ASCO transfer switches, and Avtron load bank equipment.

The company's core technology stack is mechanical and electrical rather than software-based: EGSA-certified technicians perform on-site installation, repair, preventative maintenance, load bank testing, and fuel testing/polishing. Differentiated offerings include Annual Service Contracts (recurring maintenance with 24/7 priority service and full-year warranty extension), commercial generator rentals from 20kW to 500kW, and engineered load sizing with full permit management across NY/NJ/CT jurisdictions. All technicians are certified by the Electrical Generating Systems Association (EGSA), and the company is a BBB Accredited Business with an A+ rating.

The business model combines one-time hardware sales, project-based installation revenue, recurring service contracts, transactional repairs (including warranty work billed to manufacturers), and usage-based rentals. Kris Schwind, the founder's nephew, has led the company as CEO and Owner since 2009, during which time technician headcount has more than tripled. Customer segments span residential homeowners, healthcare providers, grocery and food service, commercial real estate, education, municipal government, utilities, entertainment venues, and cultural institutions.
