If a repair shop does not have a refrigerant recovery machine (and a certified technician who knows how to use it), they cannot legally service your A/C system.ДЄs of March 2020, the EPA published a new rule revising its previous rules that prohibited the venting of all refrigerants into the air when servicing a vehicle, whether or not they contain CFCs or global warming gases.

Refrigerant recovery requires a refrigerant recovery machine that meets Society of Automotive Engineers (SAE) standards: SAE J2209 for R-12, or SAE J1732 for R-134a, or J1770 for a combination R-12/R-134a recovery machine. R-12 can damage the ozone, and R-134a is a greenhouse gas that contributes to global warming. Refrigerant recovery prevents refrigerant from escaping into the atmosphere. When the air conditioning system on your vehicle is serviced, federal law requires the old refrigerant in the system to be recovered BEFORE any repairs are made that require opening up the A/C system.
