HVAC: EPA 608 Certification Study Guide Questions and Answers | Latest Version | 2024/2025 | Rated A+ Are there alternative refrigerants that can be directly used in systems originally designed for R- 12? Why or why not? No, because these new refrigerants are not compatible with the lubricants and oils used in R- 12 systems. Explanation: The oils and lubricants in R-12 systems cannot properly interact with newer refrigerants, making direct replacements unfeasible. What type of o...
