Historically, EPA has required that persons servicing, disposing, or recycling air-conditioning (other than motor vehicle air conditioning) and refrigeration equipment certify to the appropriate EPA Regional Office that they have acquired (built, bought, or leased) refrigerant recovery or recycling equipment and that they are complying with the applicable requirements of this rule. This certification must be signed by the owner of the equipment or another responsible officer and sent to the appropriate EPA Regional Office. However, EPA no longer requires that persons servicing stationary air-conditioning and refrigeration equipment certify that they have acquired refrigerant recovery or recycling equipment and that they are complying with the applicable requirements

Equipment must still meet EPA standards. Equipment certified to meet these standards can be identified by a label that states: "This equipment has been certified by AHRI/UL to meet EPA's minimum requirements for recycling and/or recovery equipment intended for use with [appropriate category of appliance]."
