Study Material Information:

The C38 Refrigeration Contractors Exam Manual briefly covers the major topics of the State exam including Basic Electrical Formulas, Electrical materials, Insulating Materials, Refrigerants, Refrigeration Materials and Tools, Mechanical Refrigeration Systems, Absorption Refrigeration Systems, and Electrical Plan and Circuit Symbols. The manual also contains summaries of the Uniform Mechanical Code. The last section of the Refrigeration Manual covers the Health and Safety Orders.

The Math Review Lecture covers the math formulas in the first part of the Refrigeration manual. The Health and Safety Lecture covers the Health and Safety Orders at the end of the Refrigeration manual.


Do not memorize the sample practice exam questions. This is a multiple-choice examination with four choices per question. Some questions require mathematical computation. Examination questions are written to provide only one BEST answer and are NOT written as trick questions. There is no penalty for guessing. If you are unsure about a particular question, it is better to try to answer the question than to leave the question blank.

Ample time is provided to answer all examination questions, so be sure to read each question and its four choices completely and carefully before selecting the BEST possible answer to the question.
