If you've done some HVAC work but find yourself stumped the first time you work on a freezer or frig, then you need this book!. This is a world of oil losses, hard to know line pressures, strange refrigerant valves and controls and head masters, etc. And this book will explain them all to you with lots of plain talk, plain examples, great drawings, and even a cd-rom of animation. And best of all, it has a page of "Rules of Thumb", such as; High Efficieny (seer) condenser splits = 20 degrees and below. And since refrigerant recovery of freezers and frig's are far more common place than HVAC work, it covers several methods of evacuation and recovery. This book has lots of troubleshooting notes and lots of pictures and all the basics of refrigeration from motors, capillarys, TEV'S and defrosters through superheat and critical charging and so much more. I own many hvac books and this one absolutely stands out as a 'must have' book ! Another good book to have when you want to "master" the trade, is Technician's Guide to Refrigeration Systems'by Corinchock. And of course, Troubleshooting and Servicing Modern Air Conditioning and Refrigeration Systems by Tomczyk. Warning that Tomczyk's book is sold as several books, each with a few chapters, so only buy the complete book I mentioned above, else you will have duplicate text.

the book is well put together and provides well thought out information, as well as being in depth enough to help anyone serious about the HVAC/R trade. I hate spending money for bad books and am happy to recommend this book for purchase. Buy it.

The book is written for beginning students as well as A/C techs wanting to learn more about refrigeration. It is written in everyday language for a tech to understand. It provides a good foundation for anyone wanting to get into the refrigeration field

I bought this book for my husband who works in HVAC-R. He absolutly loves it! He has many books,but this one is the most helpful and even comes with a diagnostic disc for diagrams and troubleshooting. A real helpful and affordable deal. It has a lot of refrigeration tips that he was looking for.

It is helpful i expected more info on walkin refrigerators.

If you are looking to move from air-conditioning to refrigeration service,all the information you need is inside this book!!

This book has helped me to understand a lot more in A/C system.

At first glance, many will pass this book by as too expensive. Don't make that mistake! Mr. Wirz gives thorough coverage to the subject in 380 pages. The book is packed with solid troubleshooting information. Especially valuable are pages 179 to 195 which discuss "diagnosing nine system problems". There is a drawing for each system showing pressures and temperatures for a cap tube system and a TXV system. Very helpful.

I have worked in industry on large refrigeration units (50-200 tons) for 25 years. If only I had this book years ago. I purchased Doolins Doolin's Trouble Shooters Bible: Air Conditioning, Refrigeration, Heat Pumps, Heating, 5th Edition, which turned out to be refrigeration troubleshooting history. Sent it back for this instead.

It seems clear to me that Mr. Wirz is more interested in educating people than writing to sell a book. Thanks for the effort!

book not what I anticipated, not much on refrigerated systems, good if you want to learn the overall operation on normal hvac systems. expected much on refrigeration systems, got disapointed, not worth the cost of book.

I think this is a very user friendly book that will help anyone better understand the refrigeration field better.
