Refrigerant Charging and Service Procedures for Air Conditioning Workbook Workbook – January 1, 2020

for me in the professional field of HVAC, these are a great companion for anyone who knows about this wonderful trade. even if you don't know the how to, this a great book for those who want to know what the tech is doing to your unit, I do not recommend for someone who wants their hand on this trade, you have to know what you are doing and this is not for everyone, but the book really explains on how to use your tools to make sure you get it right the first time.

Excellent training material. Well presented with good illustration

This workbook is extremely helpful in checking and correcting your understanding of the concepts and principles covered in the actual book. The questions are numerous and detailed. The accompanying answer sheet is great to check your answers and ensure you either "got it right" or figure out why you didn't. I highly recommend!

this is worth buying

When you buy a brand new book for full price you expect a book that’s not bent and permanently creased on the corners.

This is an absolute necessity for students, trainees or anybody in the hvac field. Accompany the workbook with the ebook or paperback and your ready to learn. Highly informative and focuses on the meat and potatoes of learning. Provides clarity and understanding in all the right topics. Touches on everything from how to vacuum a system, superheat, subcool, recovery etc. Highly recommend

Excellent book for learning the correct procedures serving A/C and heat pump units. Nice read for getting ready for the EPA 608 test.
