Two authors, kept separate
The charging manual is Craig Migliaccio's. Unconformed is Bryan Orr's, included here as a separate title. It is not an HVAC procedures book.
Refrigerant Charging and Service Procedures for Air Conditioning, 2nd Edition. Craig Migliaccio's charging and service manual, written step by step in the order the work happens. The 2nd Edition adds new tools, updated procedures and the A2L refrigerants R-32 and R-454B.
Unconformed: An Unbound and Unbridled Path to Unstuck Growth. A separate title by Bryan Orr. It is not about refrigerant, pressures or procedure, and it is not by Craig. It is included here as the second book in the bundle.
These two are not a course and a workbook. They are a technical manual and a book about growth, bought together at $5 off the separate prices.
The charging manual gives you the procedure side:
- Total Superheat and Total 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, with the tools and handling they require
If all you want is the procedure side, buy the charging manual on its own, or pair it with its Workbook or the Quick Reference Cards instead.
Free shipping within the USA. Orders normally leave within one to two business days. Returns are accepted within 30 days in resalable condition; the full terms are on the refund policy page.
The technical half does the work.
Craig Migliaccio holds an HVACR Master License in New Jersey, is licensed by the state to teach HVACR, Sheet Metal and Building Maintenance, has over 16 years in the field and runs an HVAC contracting business. The charging manual reads like that: what to measure, where, what the number means, what to do next.
See what is in the A/C bookThe other half is not about refrigerant.
Unconformed: An Unbound and Unbridled Path to Unstuck Growth is written by Bryan Orr, not by Craig Migliaccio, and it is a different kind of read. We are putting it in this bundle as a separate title rather than as a companion volume, so you know exactly what you are getting: one manual, one book about getting unstuck.
See every titleIf you only want the manual, say so.
This bundle makes sense if both books appeal. If only the charging side does, the manual is sold on its own, and the combos that add the Workbook or the Quick Reference Cards will serve you better than this one. We would rather you bought the right bundle than the bigger one.

★★★★★
"I have spent many years attending the finest courses and colleges to perfect my trade, however you are never too old to pick up new information and tips from other tradesmen. After scouring through literally thousands of YouTube videos, I came across AC Service Tech. I was astounded by the professionalism of this channel and the gentleman that runs it, and if you are a perfectionist, you can spot another perfectionist! I can't help thinking 'If I had my time again, I would love to have been taught by this guy'. Thank you for being an awesome resource."— Stuart B., England, UK
Questions before you order
