Exceptional HVACR exam prep for students and technicians

Guide to the NATE, ESCO, and EPA 608 Certification Exams streamlines HVACR exam prep for students and service/installation technicians alike. The text is divided into three parts: Study Guide, Questions (2,500+) and Answers. Each part is divided into the same sections and topics. Study questions correspond with the study guide, supporting mastery and retention.

The fully updated 4th Edition now covers ESCO exams, along with the latest HVACR technologies. Previously available only in print, the new edition is now offered as a Pearson+ eTextbook. It’s also available with a MyLab product developed specifically for this title.

Hallmark features of this title

Concise yet comprehensive exam coverage

  • Nearly every aspect of the NATE, ESCO and EPA 608 exams is covered across the study guide content and related questions.
  • Study questions correspond with study guide topics. Students benefit by first reading a section of the study guide (Part I), then answering the associated questions (Part II) and, finally, confirming the accuracy of their responses (Part III).
  • Troubleshooting concepts help students think like technicians while performing better on exams.

Learning aids

  • 2,500 multiple-choice study questions organized by topic mimic those found on the actual certification exams.
  • Numerous electrical and mechanical diagrams assist the visual learner.
