Ratings and reviews

I am a comm. Refer. Tech. Who's at JOURNEYMAN LEVEL, I absolutely suggest every person who wants to get into the world of refrigeration including air conditioning I suggest you get these books or go to school you're going to have to get books anyway but you need to pass them EPA certificates once you get them you got open road brother, as long as the customer knows you're trying to do everything possible that you know of to get them up and running time is money in this industry even maintenance PMS preventing and maintenance it's very lucrative. Me personally I've worked about 30 years in the industry I started out learning how to make ductwork, was taught how to hang ductwork, and I learned the calculations that you need for correct air flow and building pressures in and out at that time my life I was 17 18 years old. And I just one day got up the courage to ask my neighbor if you would need an apprentice. Now I am 44 years Young and got seriously hurt, now disabled, 2teachismypassion

Craig gives some of the best and most informative breakdowns I've ever seen. I wish there was content like his when I was coming up in the trade. This book is a must buy for anyone looking to enter the trade, and for those who recently have.

Awesome book I own both paperback and ebook that way I always have a copy with me.
