Most HVAC books explain the topics but leave out the procedure. These two were written the other way round: step by step, in the order you actually do the work in the field.
The 2nd Edition of Refrigerant Charging and Service Procedures for Air Conditioning covers new tools, updated procedures and the A2L refrigerants, including R-32 and R-454B. Inverter Mini Split Operation and Service Procedures covers the ductless side, where fixed superheat and subcooling targets no longer behave the way they do on a single speed system.
Between the two paperbacks you get:
- Total Superheat and Subcooling, and which metering device calls for which
- The total weight charging method, including refrigerant per foot of line set
- Recovery, evacuation and the vacuum procedure
- Leak detection methods and pressure testing limits
- A2L refrigerants: R-32 and R-454B, tools and handling
- Inverter mini split operation, commissioning, flaring and diagnostics
- Troubleshooting sequences with the readings that point to each fault
Free shipping within the USA. Orders normally leave within one to two business days. Returns are accepted within 30 days in resalable condition; see the refund policy page for the full terms.
Procedures you carry out, not just theory you read.
Craig taught HVACR to high school and adult students before writing any of this down. The books follow the order of the job: what to measure, where to measure it, what the number means, and what to do next. That is the gap he could not find a book for, so he wrote one.
See what is in the A/C bookBoth sides of the trade in one set.
Ducted split systems and ductless mini splits do not diagnose the same way. Charging an inverter unit by the numbers you would use on a single speed condenser will send you down the wrong path. This combo covers both so you are not guessing when the next call is a mini split.

Keep them beside the P/T Chart and the HVAC calculators. These are books you open again when the next unit does something you have not seen before, not ones you read once and shelve.
