WHY THIS APP IS DIFFERENT

- Built for the 2026 rules. The refrigerant world changed on January 1, 2026: the AIM Act leak-repair program now covers HFC appliances down to 15 lb, with 10/20/30% leak-rate triggers, and A2L refrigerants are entering the field. Many EPA 608 study guides still teach pre-2026 numbers. Every question here reflects the current rules, and 2026 changes are marked with a badge so you know exactly what is new.

- Every answer cites its source. No mystery answers. Each explanation names the regulation or standard behind it: 40 CFR Part 82, the Part 84 HFC rules, DOT cylinder requirements, ASHRAE classifications. If we can't source it, we don't ship it.

- One-time purchase, no subscription. Try the app free, then unlock everything forever with a single purchase. No monthly fees, no accounts, no ads.

- 100% offline. Study in the truck, in the shop, in the mechanical room. Nothing to sign into, nothing to sync.
