Now in stock. The companion workbook to the 2nd Edition of Refrigerant Charging and Service Procedures for Air Conditioning. Over 1,600 questions across six question types, including image questions, so you work the material instead of only reading it. Free shipping in the USA.
Over 1,600 questions
Six question types, including image questions where you read a gauge or a nameplate and say what it tells you.
Matched to the 2nd Edition
Built around the updated manual, so the sections line up chapter for chapter with what you are reading.
This is practice material, not a second manual. It does not re-teach the procedures. It asks you about them, over and over, until the answers come without the book open.
Reading a charging procedure and being able to run it on a unit with a customer watching are two different things. The workbook is the part in between. It pairs with the 2nd Edition manual, which is sold separately and is where the procedures themselves are explained.
What you get out of it:
- Over 1,600 questions across six different question types
- Image questions, where you read what is in front of you and interpret it
- Chapters that follow the manual, so you can work a section the same evening you read it
- Repetition on superheat, subcooling and the charging methods until the targets stick
- A way for instructors and trainers to set work and check it
- Self-testing before a licence exam or a new hire review
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.
Reading it once is not knowing it.
Most techs who struggle with charging do not lack the information. They have read it and it has not set. Questions force recall, which is the part that makes a procedure available to you at eight in the morning on a roof.

Multiple choice on its own only tests recognition. The mix here makes you produce the answer, and the image questions put a reading or a nameplate in front of you and ask what it means, which is closer to what the job actually asks of you.

★★★★★
"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
Does the manual come with this?
No. This listing is the workbook on its own. The 2nd Edition manual is a separate listing, and the two are meant to be used together.
Can I use the workbook without the manual?
You can, but it is not designed that way. The workbook tests the procedures; the manual is where they are taught. Without it you will be checking answers you were never shown.
How many questions are in it?
Over 1,600, across six question types including image questions.
Is it matched to the 2nd Edition?
Yes. It is the companion to the 2nd Edition, the one that adds new tools, updated procedures and the A2L refrigerants including R-32 and R-454B.
Is this suitable for a class or an apprenticeship?
Yes. It was written by a state-licensed HVACR instructor and works as set work for students or new hires, as well as for self-study.
How fast does it ship, and what if I need to return it?
Orders normally leave within one to two business days with free shipping inside the USA. If it is not what you needed, tell us within 30 days for a refund; the full terms are on the refund policy page.
