PSC L041

Overview

The Product Service Code (PSC) system categorizes goods and services used by the U.S. federal government for procurement, enabling standardized classification in systems such as FPDS and SAM and supporting consistent tracking, reporting, and analysis. The PSC Manual on Acquisition.gov is the authoritative source for PSC content, management, and official descriptors.¹

PSC L041 — Technical Representative‑ Refrigeration, Air Conditioning, and Air Circulating Equipment — is the PSC descriptor applied when an acquisition’s primary deliverable is technical‑representative services related to refrigeration, HVAC, and air‑circulating systems. Agencies use L041 in award records and procurement reporting to identify technical‑representative activities tied to those systems.¹

Assignment and role (agency context)

Agencies assign technical representatives to perform non‑contract‑administration technical duties and to provide liaison, guidance, and assistance for specific programs. DFARS Subpart 242.74 defines the role, clarifies that technical representatives perform non‑CAS technical functions, and distinguishes them from CORs and contracting officers’ administrative roles.²

Frequently asked questions

• Q: What specifically does PSC L041 represent in FPDS entries?
  A: PSC L041 is the recorded PSC descriptor for technical‑representative services tied to refrigeration, air‑conditioning, and air‑circulating equipment; use it in award and transaction data when the primary service is technical representation.¹

• Q: How is L041 different from J041 or N041?
  A: L041 covers oversight/liaison/technical support (technical‑representative services). J041 covers maintenance and repair; N041 covers installation. The PSC Manual groups these as distinct service types for reporting.¹

• Q: Who may serve as a technical representative for an L041 contract?
  A: Agencies appoint qualified personnel to act as technical representatives. DFARS Subpart 242.74 clarifies duties and limits: technical representatives perform technical functions and are not contract‑administration or audit representatives.²

• Q: When should procurement staff select L041 versus other PSCs in solicitation or award records?
  A: Choose L041 when the contract’s primary deliverable is technical‑representative services for refrigeration/HVAC; select maintenance, installation, or modification PSCs when those outcomes are primary.¹
