    • Great book! Anyone in class or new to the field should get it.
Format: Spiral-bound
Love this book. I’m in HVAC School and this is really clear and is helping me so much with everything we are doing in class tremendously. Pics and descriptions are clear. There’s a bit of a catch 22 I’m learning as people in the field don’t actually do these “best practices,” and if you’re boss has been doing it 30 years and does stuff wrong, you can’t tell them they are wrong. My friends in the field seem to think class and books like this are pointless, which has me scratching my head. On a different note, there is nothing electrical here. I think it would be amazing if he came out with an HVAC electrical diagnostic equivalent because all the electrical books out there are just as bad as all the HVAC tech books that are 5000 pages and written in technical jargon. I have one electrical PDF book that got great reviews, but it’s 1000 pages and is getting way too much into the physics of it all... come on. I just got my electrical certification and I want to know how to repair an AC system, not master PHD electronics. The straight approach is great in this book. I think he could do something similar in electrical. I’d be the first to buy it. And great utube videos as well, which is of course presumably how his audience knows about this book. The videos are a good overview, the book solidifying the details. You can do the same with the electrical side Craig! :D Damn finding low voltage shorts and jumpers etc still confuse me. ... show more

This is a great book. I am new to HVAC but as I am reading and learning I feel as if I have been doing HVAC a lot longer. The teachings is simple and not a lot of technical jargon. Simple to the point. I have not even gotten through halfway of the book but have learned so much. What is even better is that there is a YouTube that they have that helps make the learning more effective. I just received a email from them telling me that they have a second edition on the new refrigerants which I will be purchasing as soon as I complete the first one. ... show more

This is a must have reference book for any service Tech someone trying to become a service tech. It gives all the information of a true textbook in a much more user-friendly format and style I also recommend getting the cards as they are a condensed version of everything you need from this book for quick reference ... show more

    • Great HVACR book for those in the trade.
Format: Spiral-bound
This is a very well written instructional manual, but beware that it is written for those who have some training and/or experience with air conditioning or refrigeration equipment (you have to know closed refrigeration system operation and HVACR jargon). I've had 25 years of experience in this field and I still learned a thing or two. Craig Migliachio is a wonderful teacher and a master of the trade and it show through in this book. I don't recommend this for DIYers. ... show more

    • No index and would be better if it included more information, e.g. mini split systems with pictures.
Format: Spiral-bound
Decent, but missing clarity on mini splits and there is no index at the back of the book. An index would make it easier to find what you are looking for.

    • Very easy to read and good explanations.
Format: Spiral-bound
I started hvac school recently and purchased this book as a supplement to my required classroom material. I have only read about 1/4 into the book so far but it has presented the concepts in such a way that anyone could learn and gain a basic understanding of how an hvac system works. Definitely a good read whether you are learning for the first time or just need a refresher. I have been reading it during my time off between semesters and think this book should be required material by any hvac program. I have pretty much already learned everything this book covers but it presents some things in an easier to understand less complicated way without a bunch of extra fluff and nonsense that you sometimes get in college textbooks. It is well worth the price it sells for and doesn't disappoint. ... show more

    • WOW! Just arrived but liking it!
Format: Spiral-bound
So first off, granted the book is a bit pricey. But lets face it, authors (especially technical ones!) need to make money and its not any real cost difference from all the college textbooks I have purchased! All that being said, it just arrived today but after an hour or so reading through it, I am impressed. I LOVE the large print (us older guys have trouble reading that small 10pt font used in many manuals) and I really like the graphics. Also the spiral binding is nice as it will keep the book open during use. And the gloss paper is nice as well. All things important for a book intended for field use. Next, I like the graphics and the scenario examples. The material starts with some basics (purging hoses, etc) but then goes to some advance material (taking measurements, refrigerants, etc). Seems to cover all the bases. Just enough scientific information is included to be relevant yet its not a physics book of gas properties with a ton of equations and theory many if us (myself included!) have trouble understanding. Not that those are unimportant its just to me, they are not as important in a field tech manual so why include them? So in a nutshell, looks like a great resource for HVAC techs as well as those involved in the industry. I am definitely happy with my copy! ... show more
