Welcome to Unofficial Practice Questions for the California C38 Refrigeration Contractor Exam. This book is designed to help you prepare for the California Contractors State License Board (CSLB) C-38 license exam, which certifies individuals and businesses to install, maintain, and repair commercial and industrial refrigeration systems across the state of California.
The C-38 Refrigeration Contractor classification requires knowledge far beyond simply working with cooling equipment. To pass the CSLB trade exam, you’ll need a solid understanding of refrigeration principles, mechanical components, electrical systems, system sizing, ductwork, refrigerants, EPA regulations, safety codes, and state-specific building and energy requirements. This license represents a high level of professional competence, and earning it is a key step toward expanding your capabilities and credibility in the HVACR industry. This book provides a comprehensive collection of unofficial multiple-choice practice questions that reflect the subject areas and structure of the C-38 exam. Each question is paired with a detailed explanation to reinforce your understanding, correct misconceptions, and build a strong foundation in both the technical and legal aspects of the trade.
While this resource is not affiliated with or endorsed by the CSLB, it is based on publicly available exam guides and industry-standard practices to closely simulate the types of questions and scenarios you are likely to encounter on the real test. Whether you’re a seasoned technician preparing to take the exam or a newer contractor seeking to qualify for refrigeration projects, this book will help you assess your knowledge, focus your study efforts, and gain the confidence you need to pass. Use it to identify strengths and gaps, sharpen your test-taking skills, and move forward toward your goal of becoming a licensed C-38 Refrigeration Contractor in California.
