Inverter Mini Split Operation and Service Procedures

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 HVAC (Heating, Ventilation, and Air Conditioning) trade. Technicians must know the step-by-step service procedures associated with these systems and how they differ from traditional single speed systems.

This HVAC 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 HVAC technicians with the knowledge they need to service these complex systems.
