AC Service Tech is excited to announce the new 2nd Edition of the Refrigerant Charging and Service Procedures for Air Conditioning paperback book is available. This book has 450 images on 344 pages! It includes over a hundred more pages and double the amount of images to cover.

This book is dedicated to those who are eager to learn the HVAC trade and refrigerant charging/troubleshooting practices. This book contains step by step procedures that include preparing air conditioning and heat pump systems for refrigerant, measuring system refrigerant charges, and troubleshooting systems by measuring refrigerant charge indicators, air temperature measurements, and airflow. Manifold gauge sets, digital manifold sets, digital gauge stubs, and wireless probes are discussed and utilized in examples. This book differs from others in that it provides key insights into each procedure along with tool usage from a technician's perspective, in language that is easy to understand.

Concepts are examined such as refrigerant properties, the refrigeration cycle of an air conditioner and heat pump, energy transfer, airflow requirements, components within systems, and common problems.

Procedures included in this book:

• A2L Refrigerant Changes
• R-32 and R-454B
• R-410A and R-22
• More Step-by-Step Procedures
• Wireless Probes, Gauge Stubs, Tees
• All-In-One Digital Manifold Set Use
• Compound Manifold Gauge Sets
• More Images and Procedures
• Charging and Recovery with Manifolds
• Charging and Recovery with Tees and Probes
• Detailed Troubleshooting Scenarios
• More Methods to Determine Problems
• More Airflow Testing Procedures

These three updated HVAC quick reference polystyrene cards are double sided and designed to be used with Air Conditioners and Heat Pumps to measure the refrigerant charge level in a unit, charge refrigerant, troubleshoot refrigerant based problems, and measure heat transfer to determine if there is a problem.

Info included on these cards:

• Use the P/T Chart to find the Saturated Temperature of the common refrigerants R-32, R-454B, R-410A, R-22, R-407C, R-422B, and R-438A
• Use the Guide to determine how to find the Bubble and Dew Saturated Temps of Blend Refrigerants
• Use the Refrigerant Weight Chart to calculate the amount of refrigerant needed per foot of tubing R-32, R-454B, R-410A, R-22, R-407C, R-422B, and R-438A
• Use the Guide to weigh in the full or partial refrigerant charge into an empty vacuumed unit
• Find the Target Subcooling to measure the refrigerant level of systems with a TXV metering device
• Use Subcooling to determine if a system is undercharged, correctly charged, or overcharged
• Use Delta T to determine if the system is exchanging heat properly
• Find the Target Superheat to measure the refrigerant level of systems with a fixed orifice metering device
• Use Total Superheat to determine if a system is undercharged, correctly charged, or overcharged
