The ultimate survival skill in that last category involves reclamation, where a refrigerant pulled from a system is reclaimed (brought to Air-Conditioning and Refrigeration Institute [ARI] Standard 700-1999 purity levels) and returned in mint condition. Contractors and technicians who work through local supply houses may not think much about the reclamation process. However, it is filled with legalities, standards, and close monitoring.
The Reclaimed Refrigerant Program references the ARI Standard 700-1999, “Specification for Fluorocarbon Refrigerants.” According to ARI, “Certification by reclaimers under this standard requires that the reclaimers’ refrigerants do not exceed the contaminant level established” by ARI. The following refrigerants have been subject to purity requirements:
R-11, R-12, R-13, R-22, R-23, R-32, R-113, R-114, R-123, R-124, R-125, R-134a, R-143a, R-401A, R-401B, R-402A, R-402B, R-403A, R-403B, R-404A, R-405A, R-406A, R-407A, R-407B, R-407C, R-407D,
R-407E, R-408A, R-409A, R-409B, R-410A, R-410B, R-411A, R-411B, R-412A, R-413A, R-500, R-502,
R-503, R-507A, R-508A, R-508B, and R-509A.
Refrigerants to be tested are selected from the reclaimers’ inventories by representatives of an independent testing lab under contract with ARI. Qualified participating reclaimers may display a certification symbol.
The testing focuses on high boiling residue, acidity, water content, chloride ions, particulates, solids, volatile impurities (including other refrigerants), and noncondensables.
Contractors need to be aware of the applicable ARI standards. Fines may be levied by the EPA for refrigerant sold not meeting ARI specifications.

The following is a list of ARI-certified refrigerant reclaimers as of July 1, 2002. Contractors should contact reclaimers or local supply houses to be sure certain refrigerants sent out or brought in for reclamation can be handled by the indicated reclamation facility. Also, be aware that from time to time, ARI decertifies reclaimers, so listings are subject to change.
