ASE Test Preparation - A7 Heating and Air Conditioning (Automobile Certification Series)

Look no further, If you commit to this and REALLY study it, you WILL be prepared for this ASE test. The questions in here are not the same as on the test, BUT they are written like ASE questions, and the study material in this book, will preprae you for the test. DOn't get me wrong, if you know nothing about HVAC, this book will probably not be your salvation. BUT if you already do this type of work and have a decent understanding of AC, this book will probably give you the edge to pass the test. Assuming, you Really read it, study it, and understand what you are reading.Passing an ASE test is more about understanding the way these systems work, not memorization. If you don't understand the principles of sutomotive systems, you will never pass an ASE test.

This issue was mostly in the 6th test review. As someone who is new to the industry and has an idea on these systems but doesn’t know everything the test answer key is kind of a major issue. Question 30 in the review is completely different in the key versus in the actual test and question 16 has the techs confused/reversed in the keys explanation and the answer in general. I’ve used delmar for brakes and I past the test no issues. I may not be experienced but the questions I did understand in this specific still had me question how much I can really trust this. I’ll find that out when I take my test.As far as actual content I think it’s helpful even though the practice exams seem to have been skipped by the proof reader. There were many more errors in that section than the two I specified but the book has given me hopes to pass.

Lots of information

I've had 5 years of automotive experience and thought I had a basic understanding of heating and A/C fundamentals and I was correct in the aspect of it being basic. Living in upstate NY a/c problems generally only come in half the year and it's typically a inject dye and replace line or replace obvious faulty part. Many other well informed tech I know have mentioned that this was one of their struggles for ASEs and I think the reason may be which I just explained, diagnosis around here is relatively simple and quick.Besides all that I certainly could not have passed without this book, as long as you absorb all the explanations it will help you immensely, first times I took the practice tests I did horrible, after a few retries and studying for about 2 weeks I ended up taking my ASE and passed with a 40/50.Like mentioned before I know several techs that are far more experienced than myself and they all told me that A7 took them several times to pass.Only reason I'm giving a 4/5 is compared to the other Delmar-Cengage books I've used, this one seemed to have the most amount of typos and poor editing points.

Read it before taking test. Good book

I knew about basic a/c and heating systems but nothing to become an hvac tech. Took the exam prior to this book and failed miserably, I think i scored 22. Once I read and understood how an a/c system works then I passed and I am not booksmart. There is a few schemtic diagram questions on here, but mostly a/c cooling questions.

Exactly what was needed for the mechanic in my life.

Great overall study book the practice test resemble the ASE real test pretty accurately.
