EPA Section 608 Technician Certification practice, built from the official outline
Every question here is original, written against the certifying body's published content outline, and mapped to it, documented per question. The simulator mirrors the real format: 100 questions, 120 minutes, domain-weighted sampling, and the 70% passing score the rule actually sets.

Not on the EPA 608 exam. ASHRAE 34 safety classification, the AIM Act HFC phasedown, and handling R-32 and R-454B in the field. Kept separate on purpose so exam practice stays true to the published blueprint. Drill it separately.
