Since January 1, 2025, new residential and light-commercial AC and heat pumps must use refrigerants with a GWP of 700 or less. That rules out R-410A and brings in the A2Ls, R-32 and R-454B.

“Charging is not a number you look up. It is a reading you take and a decision you make.”
A system charged by feel, or to the wrong target, runs hot, trips, or quietly wears out the compressor. Refrigerant Charging and Service Procedures for Air Conditioning turns the charging and service work into steps you carry out on the unit: where to take the reading, what it should be for the metering device in front of you, and what to change when it is off.
Since January 1, 2025, new residential and light-commercial AC and heat pumps must use refrigerants with a GWP of 700 or less. R-410A is out for new equipment; the A2Ls, R-32 and R-454B, are what is arriving on jobs now.

What the 2nd Edition covers
Superheat and subcooling by metering device, the weigh-in method, airflow checks, recovery, evacuation and the vacuum procedure, leak detection and pressure testing, and the A2L refrigerants with the tools and handling that go with them. 450 images across 344 pages.
What's inside
Four things that make the procedures usable
Each procedure in the order you do it on the unit: measure, read, decide, then move.
Gauges, probes, manifolds and readings shown as they look on the job, not as a diagram.
Manifold sets, digital manifolds, gauge stubs and wireless probes, used in the examples.
Charge indicators, air temperature and airflow readings worked through to the fault.
Real pages from the 2nd Edition
The 2nd Edition aligns with the HVAC Excellence Residential Air Conditioning task list for the Employment Ready and Professional Level exams. The companion workbook covers the same ground in over 1,600 questions, with the answer key included.
Studying for the exam? Learn the reading, not just the rule.
Certification exams test whether you understand why a reading is what it is. This book is built around the procedure and the reasoning behind it: what to measure, what the number should be, and what it tells you when it is off. It aligns with the HVAC Excellence Residential Air Conditioning task list for both the Employment Ready and Professional Level exams.

One book for the shop and the classroom.
Craig Migliaccio taught HVACR to high school and adult students before any of this was a book, and he still runs an HVAC contracting business. The procedures are written so a first-year tech can follow them and a senior tech can hand them to the crew.
Instructors and training programs can pair the book with the companion workbook and the PowerPoint sets built from it, so everyone works from the same procedures and the same readings.
