Hvac&R Reference Guide: Answerman

This is a good reference book. The only downside about this book is that the quality is really bad. I used it for one of my classes probably 4-6 times and its already falling apart, pages are coming off. I wouldn't mind paying more for better quality.

Very good reference guide

thanks

Book is published in the 70s, No charts for newer Freons ! Should NOT be in circulation

to old and did not contain the new information I needed
