The refrigerant ledger · 40 CFR 84.106
Wuzler Refrigerant Log
from $29/monthYou own or service an appliance with 15 pounds or more of refrigerant. Since 1 January 2026 the rule says: determine the full charge, calculate the leak rate on every addition, repair within 30 days of exceeding the limit, keep a record of every service visit for three years. This is the instrument those records live in, and the ticket a contractor hands the owner after every visit.
What the record is
The rule lists what a service record must contain. The ledger keeps exactly that, one card per appliance, one entry per visit: the appliance and where it is, the date, the parts worked on and the type of work, who did it, the refrigerant added or removed, the full charge, the leak rate and the method.
40 CFR 84.106(l)(2)· verified 2026-09-04Over the limit, the 30-day repair clock starts, the verification tests are scheduled, and the instrument says so in orange. Under it, it says so in white. Records are kept three years, as the rule says.

The one physical artifact
The ticket the contractor hands over
If someone other than the owner does the work, the rule says that person must provide the owner with the record. The contractor keeps the top copy; the owner gets the record.
Two one-sheets travel with it, each one Letter page in the rule's words: hand this to your contractor and hand this to your customer, as pages and as PDFs.
