The demand for inverter mini split system installations is growing rapidly due to the versatility, functionality, and electrical efficiency of these units. As a result, inverter mini split system installations and servicing are becoming more common for individuals in the HVACR trade. Technicians must know the step-by-step service procedures associated with these systems and how they differ from traditional single speed systems. This book was written to help demystify the operation of inverter mini split systems and to explain associated concepts and procedures, in a language that is easy to understand. System parts are examined individually, electrical/mechanical operation is discussed, and related troubleshooting steps are given. By examining each component individually, readers can more easily digest the information and build upon their knowledge, as they progress through the text. The goal of this book is to equip technicians with the knowledge they need to service these complex systems. Procedures Included: · Line Set Connection · Leak Testing and Vacuuming · Charging and Recovery · Guidance on Checking the Charge · Power and Communication Wiring · Electrical Component Troubleshooting · Common Problems and Diagnosis

This E-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 refrigerants 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.

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. Use the P/T Chart to find the Saturated Temperature of the common refrigerants R-32, R454B, 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, R454B, 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.
