How to check or better understand superheat and subcool

Are you still confused about how to properly measure and interpret superheat and subcooling in HVAC systems? These two concepts are the backbone of accurate system diagnostics, yet many technicians only scratch the surface when it comes to understanding how they truly impact efficiency and performance.

In this video, Tom take a deep dive into superheat and subcooling, breaking down not only what they are, but also why they’re critical to charging an air conditioning or refrigeration system correctly. You’ll learn how superheat ensures proper refrigerant vaporization to protect the compressor, while subcooling guarantees that liquid refrigerant is delivered to the metering device without flash gas. He’ll also cover step-by-step methods for measuring superheat and subcool, common mistakes techs make in the field, and how to use these readings to troubleshoot issues like low charge, restricted metering devices, or improper airflow.

Whether you’re a new HVAC technician looking to build a strong foundation, or an experienced tech who wants to sharpen your skills and avoid costly callbacks, this training will help you understand these concepts on a deeper level. By the end, you’ll be able to approach system charging and diagnostics with confidence, precision, and speed.
