PSC H341

Overview

The Product Service Code (PSC) system standardizes how the U.S. federal government classifies products and services in procurement reporting. PSCs appear in FPDS and SAM to indicate what was bought, support spend and market analysis, and enable consistent cross‑government reporting. The PSC Manual and its SOP maintain the official code set and the change process. ¹

PSC H341 — INSPECTION- REFRIGERATION, AIR CONDITIONING, AND AIR CIRCULATING EQUIPMENT — is used to tag contract actions whose predominant deliverable is inspection services for refrigeration, air‑conditioning, or air‑circulating equipment. The manual’s H341 entry lists several includes/excludes (for example: “Commercial Testing and Laboratory Services” included; “Medical and Dental Laboratory Services” excluded). ²

The PSC Manual lists adjacent quality‑control, testing, and maintenance categories; consider these when requirements include testing or repairs. ²

Regulatory considerations

Contracts that include maintenance, service, repair, or disposal of refrigeration or air‑conditioning equipment may require clauses addressing ozone‑depleting substances and high‑global‑warming‑potential refrigerants; FAR clause 52.223‑12 prescribes contractor responsibilities tied to the Clean Air Act and EPA SNAP guidance. ³

Frequently asked questions

• Q: What is the single best source for the official H341 definition?
  A: The Product and Service Code Manual (PSC Manual) is the governing source for PSC definitions; consult the manual’s H341 entry for the official includes/excludes language and scope details. ²

• Q: Does H341 cover routine HVAC maintenance or repairs?
  A: No. H341 is an inspection code. Routine maintenance and repair activities are covered under maintenance PSCs such as J041; procurements should use the PSC that best reflects the predominant deliverable. ²

• Q: Are environmental clauses required on contracts carrying H341?
  A: If the work involves servicing, removing, or disposing of refrigeration equipment or refrigerants, FAR 52.223‑12 and related environmental clauses may apply because of ozone‑depleting substances and high‑GWP refrigerants. Review contract specifics and applicable FAR provisions. ³

• Q: Which PSCs should be considered for solicitation language that includes inspection plus testing?
  A: Use H341 when inspection is predominant; add or reference H241 for equipment/materials testing and H141 for quality‑control services when those tasks are significant. Check the PSC Manual for guidance. ²
