Detailed study guide which introduces cooling and heating concepts. It also covers system balancing, indoor air quality, energy conservation equipment, and commercial/industrial refrigeration systems.
The information was very helpful and proved to be a great purchase. I have vastly improved my knowledge of this course.Joanna Gonzalez
I was having such a hard time to find this book but at Contractor Campus they had the books in stock! I even called before to make sure and they were such a help!
