A Great Super Fantastic Book for Learning How to Service and Repair Air Conditioners and Heat Pumps

My friend, Craig Migliaccio just finished this great book on Refrigerant Charging and Service Procedures for Air Conditioning. If you would like to see more information on the book or purchase here is the link https://www.acservicetech.com/the-book Mr. Migliaccio has dedicated many hours to this excellent book and has been kind enough to make hundreds of Youtube repair and troubleshooting videos. We feature many of these videos taken from the AC Service Tech Youtube Channel on our site! “This book is dedicated to those who are eager to learn the HVACR Trade and Refrigerant Charging/Troubleshooting Practices. In this book, you will find step by step procedures for preparing an air conditioning and heat pump system for refrigerant, reading the manifold gauge set, measuring the refrigerant charge level, and troubleshooting problems with the system’s refrigerant flow. This book differs from others as it gives key insights into each procedure along with tool use from a technician’s perspective, in language that the technician can understand. The book also explains the refrigeration cycle of air conditioners and heat pumps, refrigerant properties, heat transfer, the components included in the system, the roles of each component, airflow requirements, and common problems.”
