Technician service links
Owner-controlled records without technician accounts.
Owners create sites, assets, and covered circuit records in Subpart, then create a 48-hour service link for the technician. The technician records refrigerant added, certification number, and service notes without an account. Subpart calculates the leak-rate result from the owner’s equipment history and adds the completed record to the owner’s compliance history.
