Written by a licensed HVACR instructor
Craig Migliaccio holds an HVACR Master License and is licensed by the State of New Jersey to teach HVACR, Sheet Metal and Building Maintenance.
Same book as the mini split paperback, delivered as a file. It covers how inverter and variable speed systems operate, and why the superheat and subcooling targets you rely on for a fixed speed condenser do not transfer across.
From there it works through line set and flare work, pressure testing and evacuation, commissioning, and the diagnostic sequences for the faults that come in as service calls.
The procedures covered include:
- Inverter and variable speed operation, and how it changes your readings
- Flaring and line set work
- Pressure testing, evacuation and the vacuum procedure
- Commissioning and start-up, step by step
- Charge adjustment for line set length
- Error codes and board indications, and what to check next
- Diagnostic sequences built around the symptom you were called out for
This is a digital product. After checkout you receive a download, so there is no shipping and no delivery window. Read it on a phone, a tablet or a computer, and re-download it to your own devices as needed.
Nothing is posted, so the returns process for printed books does not apply. If a download fails or you bought the wrong format, email info@acservicetech.com and we will fix it.
Useful on the call, not after it.
Mini split work tends to arrive at short notice. A download means you can read the commissioning sequence tonight and use it tomorrow, instead of booking the job around a shipping estimate.

Most of the work on a ductless system happens where there is no bench and nowhere to put a book down. A phone copy goes up the ladder with you and lets you jump straight to the error code section while the unit is still showing it.
Read the charging proceduresThe ductless half of the range.
This covers mini splits. The Refrigerant Charging and Service Procedures for Air Conditioning title covers ducted systems, and plenty of techs carry both. Keep the P/T Chart and the HVAC calculators on the same phone.

"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
When do I get it?
Straight away. It is a download, so nothing ships and there is no delivery estimate.
Do I also get the printed book?
No. This listing is the digital edition only. The paperback is a separate listing.
What can I read it on?
Any device that opens the downloaded file, including a phone, a tablet or a computer. If you want the exact file format confirmed before buying, email info@acservicetech.com.
Is this the same as the air conditioning book?
No. This one is about inverter mini splits. The air conditioning title covers refrigerant charging and service on ducted systems. They are separate books.
Is it brand specific?
It is built around how inverter mini splits work rather than one manufacturer, so it applies across brands. Use the manufacturer literature for a specific model's figures.
