FAQ

What work fits NAICS 238220?
  • Task-order contracts to replace rooftop HVAC units and associated ductwork and rooftop curbs on occupied facilities.
  • Preventive maintenance and scheduled service contracts for boilers, chillers, pumps, and HVAC control systems with documented maintenance logs.
  • Retrofit projects to upgrade piping and hydronic heating loops, including removal, replacement, and balancing of mechanical systems.
  • Emergency response and repair orders for burst pipes, refrigerant leaks, or failed boilers requiring journeyman plumbers and certified HVAC technicians.
When is NAICS 238220 a weak fit?
  • General building construction and prime contracting: covers overall project management and multiple trades rather than single-trade HVAC and plumbing mechanical scope.
  • Manufacture of HVAC equipment: involves fabricating compressors, coils, and factory assembly operations rather than site installation and system servicing.
  • Electrical-only controls integration: centers on electrical engineering and control-system programming without the mechanical installation and piping work that define this trade.
What solicitation language points to NAICS 238220?
  • Solicitation lists trade labor categories such as licensed plumber, HVAC technician, and sheet metal worker with journey-level qualifications.
  • Requirements include code-compliance inspections, permits, commissioning checklists, and certified testing and balancing reports.
  • Deliverables specify preventive maintenance schedules, filter-change records, system performance metrics, and emergency response time windows measured in hours.
