In this professional course, you progress from foundational responsibilities and safe work habits to confident field measurement and diagnosis. You will understand how manifold gauges and hoses support correct setup and charging control, how vacuum pumps and deep evacuation remove moisture, and how micron gauges verify vacuum quality and system dryness. These skills translate directly to cleaner installations, fewer call backs, and better system reliability across common air conditioning and refrigeration applications.

You will also strengthen real world troubleshooting with leak detection tools, including electronic detection, nitrogen pressure testing, and verification methods that help confirm repairs. Temperature measurement is covered in context so you can interpret superheat, subcooling, and air side readings with confidence. For electrical diagnosis, you will learn safe testing practices with clamp meters and other electrical instruments, including meter selection and procedures that reduce risk while improving accuracy.

Throughout the ebook, core safety practices are integrated into every workflow, from refrigerant handling and recovery operations using recovery machines and cylinders to PPE and jobsite procedures aligned with legal and safe service expectations. By bringing these tools together into end to end service workflows, you will recognize common failure patterns and build a repeatable approach to HVAC maintenance and repair.
