NFPA 90A Installation of Air Conditioning and Ventilating Systems, 2015 is a great source on fire-preventing installation practices for AC systems. It categorizes all material in a logical way, according to job description, supporting each worktable with a clear example of how it should be used. It also includes a special reference section, which gives instant information on the most useful on-the-job subjects.
The book was a bit longer and took me a while to study; however, I never thought it would be precisely what I needed for the Installation of Air Conditioning and Ventilating Systems contractors license.jose luces
