Choosing a commercial refrigeration textbook can feel like a big step if you already work in HVAC and electrical trades. You need a resource that connects what you know about air conditioning to the larger systems found in supermarkets, restaurants, and cold storage. This review focuses on one specific option: Commercial Refrigeration for Air Conditioning Technicians by Dick Wirz, a 384-page trade paperback with a companion CD, listed at USD 50.00.
Quick verdict
If you are comfortable with basic air conditioning and want to move into commercial refrigeration, this book offers a structured educational path. The listed version is a like-new trade paperback from Delmar Cengage Learning, written in English and aimed at adult and further education. It comes with a CD, which can be useful for reviewing concepts outside of the printed pages.
Who it suits
This textbook is designed for technicians who are learning commercial refrigeration in a methodical way. The phrase 'for Air Conditioning Technicians' in the title signals that it expects you to already have some HVAC background. If you are a student in an adult education program or a working professional who prefers chapter-by-chapter learning, this fits well. The trade paperback format and 18.4-ounce weight make it easy to carry between home and class.
What stands out from the listed details
The book is authored by Dick Wirz, and this edition is described as revised, which means it has been updated within its publication cycle. It includes 384 pages, so it is substantial enough to cover multiple refrigeration topics. The included CD gives you supplementary material that can help if you learn by doing or by following along digitally. The like-new condition indicates the copy has been well cared for, which matters when you are buying a used textbook.
Meaningful trade-offs
Because the publication date is 2006, this edition will not reflect the latest refrigerants, electronic expansion valves, or IoT-based controls that have become common in newer commercial systems. It is a textbook, not a quick-reference field guide, so expect to read through sections rather than jump straight to a symptom-based fix. Also, the supplementary material is on a CD, so you will need access to a computer with a CD drive to use it.
Bottom line
At USD 50.00, this textbook gives HVAC and electrical trades readers a focused way to understand commercial refrigeration through the lens of air conditioning knowledge. The revised like-new edition and the included CD add to its usefulness as a training tool. If you need the most current equipment coverage, this older edition will not be your only resource, but for building a solid foundation in commercial systems, it is a practical purchase.
Commercial Refrigeration for Air Conditioning Technicians by Dick Wirz with CD
For anyone in the HVAC and electrical trades who wants to cross-train into commercial refrigeration, this book stands out for its author-specific approach and its CD companion. The main limitation is the 2006 publication date, which means you will need to supplement it with newer reference material for today's equipment. Yet for the listed price of USD 50.00, you get a like-new 384-page textbook that connects commercial refrigeration to the air conditioning knowledge you may already have.
