Refrigerant Leak Rate Log

Track refrigerant additions per appliance, compute the annualized leak rate on every addition, and see which appliances are over their threshold, when repairs are due, and which records are missing. Runs entirely in your browser; nothing is uploaded.

Rule 1: ozone-depleting refrigerants (Section 608) Applies at full charge of at least (lbs)

Rule 2: HFC refrigerants (AIM Act rule) Applies at full charge of at least (lbs) Applies to additions on or after

Defaults come from 40 CFR 82.152 and 82.157 (Section 608) and 40 CFR part 84 subpart C (AIM Act). Rules change; confirm which one applies to each appliance before relying on a result.

Not legal or compliance advice, and using this tool does not make anyone compliant. It applies the EPA annualizing leak-rate formula and the thresholds and rules you set to the records you enter. It does not model exemptions, extensions, retrofit or retirement plans, seasonal variance, refrigerant added right after a repair, technician certification, or recordkeeping and reporting duties beyond the flags shown. Federal rules have changed several times and states can add their own. Confirm which rules apply with EPA guidance or a qualified advisor, and keep your original service records.
