The only iOS app built for EPA 608-certified HVAC technicians that generates signed, legally-compliant service records — right on the job site. AIM Act ER&R COMPLIANT — 2026 UPDATE The AIM Act expanded mandatory refrigerant logging to all systems with 15+ lbs of HFC (R-410A, R-454B, R-32, R-134a). That's thousands of rooftop units that weren't covered before January 1, 2026. 608Log handles the new threshold automatically — correct calculations, correct forms, no guesswork. WHAT EVERY TECH NEEDS ON EVERY CALL • Signed EPA compliance PDF — generated on your phone before you leave the roof • Customer signature capture — on-device, attached to every record • Auto-calculated leak rates — based on your system's full charge, every time • Repair deadline tracking — push notifications at 7 days and 2 days before your 30-day EPA clock runs out • Email record to customer — one tap after saving, satisfies the ER&R owner-notification requirement • iCloud sync — your records are on every device and accessible on demand for any inspector 7 FREE FIELD TOOLS — ALWAYS FREE • Pressure-Temperature chart (all major refrigerants) • Superheat & Subcooling calculator • A2L charge limit calculator (R-454B, R-32) • Airflow / Delta-T calculator • Electrical — capacitor & amp draw • Fixed orifice superheat • R-22 / R-404A / R-410A retrofit guide EPA violations cost up to $70,000 per day.

Your EPA cert number prints on every record automatically. Covers 40 CFR §82 (Section 608), 40 CFR §84 (AIM Act ER&R), California CARB RMP 14-day repair window, and industrial process 120-day extended deadlines. 3 years of records.
