Short answer
Recover means removing refrigerant from equipment into a cylinder. Recycle means cleaning it for reuse, usually on site. Reclaim means reprocessing it to the purity of AHRI Standard 700, verified by a laboratory, which only an EPA-certified reclaimer may do before the refrigerant is sold to a new owner. As HFC supply tightens under the AIM Act, reclaimed refrigerant is becoming a key service supply.
Refrigerant reclaim is the process of reprocessing used refrigerant to the same purity standard as new product, verified by a laboratory, so it can be legally resold. It is different from recovering refrigerant from a system and from recycling it for reuse in the same owner’s equipment. EPA’s definition ties reclamation to AHRI Standard 700, and the work must be done by an EPA-certified reclaimer. With HFC production being phased down under the AIM Act, reclaimed refrigerant is a growing part of the supply for service work on existing systems.
What is the difference between recover, recycle and reclaim?
The three terms are often mixed up. EPA’s Section 608 rules use them with specific meanings:
| Term | What it means | Who can do it | Can it be sold? |
|---|---|---|---|
| Recover | Remove refrigerant from a system and store it in an external container, with no testing or processing | Certified technician using certified recovery equipment | Not by itself |
| Recycle | Clean refrigerant for reuse, normally by separating oil and removing moisture with filter-driers or recycling machines | Technician on site or in a shop, using recycling equipment | Generally only back to the same owner’s equipment |
| Reclaim | Reprocess to AHRI 700 purity, verified by laboratory analysis of each batch | EPA-certified reclaimer | Yes, to a new owner |
The simplest way to remember it: recovery moves refrigerant, recycling cleans it, reclaiming restores it to new-product specification. Check the definitions in 40 CFR Part 82, Subpart F, for exact wording.
What is AHRI Standard 700?
AHRI Standard 700, Specifications for Refrigerants, defines purity limits for new and reclaimed fluorocarbon refrigerants. It sets maximum levels for moisture, chloride, acidity, high-boiling residue, non-condensable gases and other contaminants, and it describes the test methods. EPA’s reclamation definition refers to the appendix to Subpart F, which is based on AHRI 700, and EPA’s certification checklist currently cites the 2016 edition. Reclaimers certify that every batch is processed to the applicable specification and verified by a laboratory using the standard’s methods.
Third-party programs exist too. AHRI runs a certification program that confirms the participating laboratories are performing the testing correctly.
Who may reclaim refrigerant in the United States?
Only reclaimers certified by EPA may legally reprocess used refrigerant for resale. The reclaimer has to:
- apply to EPA and certify that it will process each batch to AHRI 700 specifications;
- use an independent laboratory to verify purity;
- report the quantities received and reclaimed, and keep records; and
- keep waste emissions within the limits in the rules.
The technician’s role is to recover refrigerant correctly, label the cylinder, avoid mixing refrigerants and send the material to a reclaimer or a distributor that handles returns. Mixed refrigerants are difficult. Reclaimers may reject mixed or contaminated cylinders or charge extra to dispose of them.
Why does reclaimed refrigerant matter now?
HFC use is being reduced under the AIM Act, which directs EPA to cut production and consumption by 85% by 2036. As the allowance schedule steps down, virgin supply for older refrigerants such as R-410A and R-404A becomes more limited, and the installed base of equipment keeps running for years. Reclaimed refrigerant is allowed to be used to service existing equipment, and EPA’s Technology Transitions program also provides for continued use of reclaimed material in many cases. It reduces the need for new production and reduces emissions. Details change, so read what is the AIM Act HFC phasedown and the R-410A phase-out timeline, and check the current EPA pages.
Reclaimed material for older ozone-depleting refrigerants such as R-22 has been the main source of supply since production ended in 2020. That experience shows how the market behaves when virgin supply ends: reclaimed stock is limited and its price reflects it.
How should technicians handle recovery to keep refrigerant reclaimable?
Quality at the job site decides whether a cylinder is worth anything later.
- Use the right cylinder. Use cylinders approved for the refrigerant, with the correct color and label. Never put a flammable A2L or A3 refrigerant into a cylinder not rated for it.
- Do not mix. One refrigerant per cylinder. If you are not sure what is in the system, check the nameplate and, if needed, use a refrigerant identifier before recovery.
- Do not overfill. Cylinders must not exceed 80% liquid fill, to leave space for expansion.
- Use certified recovery equipment. EPA requires equipment certified to AHRI Standard 740 for stationary systems, and recovery to the required vacuum level before opening a system.
- Keep records. Record the type and quantity recovered, the date and the disposition of the cylinder. These records also support leak rate calculations; see EPA 608 leak repair rules.
- Avoid contamination. Burnt oil, acid and moisture from a failed compressor can contaminate refrigerant. Learn the signs in compressor burnout causes and symptoms and how oil analysis can help check the system before restarting.
Can recycled refrigerant be reused in my own equipment?
Under the Section 608 rules, recycled refrigerant can generally be returned to the same owner’s equipment without being reclaimed. Selling or transferring it to a different owner requires reclamation to AHRI 700 purity. Some owners with several sites and large inventories use recycling equipment on site to reduce costs, but the rules about ownership and records still apply. Confirm the details in the current rule before setting up a program.
What about disposal of cylinders and refrigerant?
Releasing refrigerants to the atmosphere is generally prohibited. The Section 608 venting prohibition applies to ozone-depleting substances, and under the AIM Act EPA extended similar prohibitions to HFCs and their substitutes, with limited exceptions. Disposable cylinders must be emptied to the required level before disposal. Unwanted or contaminated refrigerant should go to a reclaimer or a hazardous waste channel, not into the air.
How do reclaimed and virgin refrigerants compare?
- Quality. Reclaimed refrigerant meets the same published purity specification as new refrigerant, verified by lab analysis.
- Supply. Reclaimed volumes depend on recovery from retired systems, so availability varies by refrigerant and region.
- Price. It can cost more or less than virgin product depending on the market and the refrigerant.
- Documentation. Ask for the reclaimer name, batch information and certification on the cylinder tag or paperwork.
- Warranty. Some manufacturers have positions on reclaimed refrigerant in warranty equipment. Check the equipment documentation.
Frequently asked questions
Is reclaimed refrigerant as good as new?
If it was reprocessed to AHRI Standard 700 and verified by laboratory analysis, it meets the same purity specification as new refrigerant. Ask for batch information when you buy it.
Can I reclaim refrigerant myself?
Only an EPA-certified reclaimer can reprocess refrigerant for resale. A technician can recover and recycle it, but selling it to someone else generally requires reclamation.
Can I put reclaimed R-410A into any R-410A system?
Yes, if it meets the specification and the system is designed for R-410A. It should not be used in equipment built for a different refrigerant, including A2L refrigerants such as R-454B; see R-454B vs R-32 vs R-410A.
