Excerpts

The HVAC/R industry has progressively become more technical. With new technology, industries are requiring their employee's skills to be updated to match the current changes. HVAC/R certification and competency tests are directed toward students and technicians at all skill levels. The National Certification Competency Exams are being offered by many organizations, including Air Conditioning and Refrigeration Institute (ARI), North American Technician Excellence (NATE), Refrigeration Service Engineer Society (RSES), and the ESCO Institute (HVAC Excellence). Guide to the HVACIR Certification and Competency Tests, 2Eis designed to help students and technicians pass competency and certification exams. The book is divided into three parts: a Study Guide, Questions, and Answers. This guide covers: System Components and Tools, Electrical Theory and Application, Airflow Components and Duct Fabrication, Indoor Air Quality and Safety, and Commercial Refrigeration and Hydronic Heating. The Questions and Answers sections cover one additional topic: Service and Troubleshooting. The student/technician will benefit most by reading the Study Guide first. Then, the student should turn to the Questions for the related statement. For example, the first statement in question 1 of "System Components and Tools" under Hand Tools reads, "A torx driver has a star shaped head and is used on torx type screws." The student would then turn to the same section in the Questions and try to answer question 1. In Section 4 of the Study Guide, an EPA Certification Study Guide has been provided to assist the student in successfully passing Type I, II, III, and Universal Recover/ Recycle Certification Examinations. This new edition includes two new sections, "Commercial Refrigeration" and "Hydronic Heating:" As a result, troubleshooting questions have been added, bringing the total to 2,200. These sections have been added to better prepare technicians in passing Certification and Competency Exams. It is the hope of the authors that all of the information provided in this book will assist the student in successfully passing certification exams offered by any HVAC/R national organization.
