## What is Smart Serve Practice ON 2026?

Get ready for your EPA Section 608 refrigerant handling certification. EPA 608 certification is federally required for any technician who maintains, services, repairs, or disposes of appliances that could release refrigerants. This app covers the Core section plus Type I, Type II, and Type III so you can walk into the exam prepared and confident.
WHAT YOU GET
- 120 original practice questions covering the Core universal foundation, Type I small appliances, Type II high-pressure, and Type III low-pressure topics: refrigerant types (CFC/HCFC/HFC), recover/recycle/reclaim, leak-rate rules, cylinders, recovery vacuum levels, and safe handling.
- Plain-English explanations for every answer so you understand the reasoning, not just the answer.
- Timed mock exams that mirror the real test format and pass mark.
- Study by certification type to focus on your weak spots.
- Progress saved on your device — no sign-up required.
- Works offline: study on the job site, on a break, or at home.
- Available in English, Spanish, and Portuguese.
