What the AIM Act ER&R rule adds
The EPA’s emissions reduction and reclaiming rule adds leak repair and recordkeeping duties for covered HFC appliances. For technicians, the main change is that leak management becomes part of routine service work, along with keeping the right documentation.

Which appliances and refrigerants
The rule applies to certain HFC appliances that meet the EPA’s charge threshold. If you work on these systems, plan to treat leak repair requirements as part of your normal maintenance and service process.
For tracking work by system, see leak rate tracking.
Records and reporting
Keep service notes that show what was inspected, what was repaired, and when refrigerant was added or recovered. If a system needs ongoing attention, record enough detail to explain the leak history and the actions taken.
For a fuller checklist, read EPA 608 recordkeeping requirements.
Technology transition dates
The EPA also uses technology transition limits to restrict certain refrigerants in new equipment. That means technicians should watch for refrigerant changes during installs, replacements, and upgrades, especially when comparing older systems with newer models.
R-410A
R-410A is part of the refrigerant transition conversation, so replacement planning should account for equipment-specific requirements and the refrigerant used in the new system.
R-134a
R-134a is another refrigerant affected by the broader transition landscape, so confirm what the new equipment calls for before service or replacement work.
R-404A
R-404A also comes up in transition planning, especially when a job involves older refrigeration equipment and a move to a different refrigerant blend.
What to do now
Review the EPA sources, update your service forms, and make sure your team knows when leak repair documentation is needed. If you want a simple way to organize system history and reminders, HVAC Refrigerant Log can help you track maintenance workflows for recurring service.
