 How it works:

Air Conditioning Masterclass Online is a pre recorded online training course.  There will be three training sessions each lasting about 2.50 hours.   

Students will be able to access the recordings at any time during the duration of the course and as many times as they wish.  

Lesson one will be made available immediately upon registration. The remaining two lessons will be made available a week after sign up.

A .pdf handout booklet of course materials will be available for download for each class.  Most class sessions will have homework.  

Each individual student must be enrolled and paid for separately.  Each student will receive a unique access code to attend each session.  Access codes may not be shared.  If you are enrolling multiple students, or a single student who is not yourself, you must provide the first name, last name, and email address of the participant(s).  All course correspondence will be directed to the participant(s).

Class sessions will remain available to enrolled students for an entire year after the start of the course.  Due to the advanced nature of this course, it is recommended that students review the material several times before the conclusion and practice the exercises in the field. 

It is assumed that by enrolling in this course, that students are already employed in a role involving air conditioning work and are ready to move into a role requiring greater skill and knowledge.  Apprentices, Install helpers, Maintenance technicians, and service technicians who are want to uplevel their careers are excellent candidates for this accelerated learning course.  This course is not meant for homeowners or building owners who want to “DIY”.  Nor is it meant as pre occupational training.  This class is intended as supplemental training for HVAC professionals who are already in the trade.

Students must have access to a stable internet service with enough bandwidth and speed to download and receive streaming video.  Desktop and laptop style computers are recommended, but tablets and mobile devices can also be used. Recording of material is not allowed. Anyone who is found to be recording the material for use beyond membership will be removed from the membership and will not receive a refund.

9 Hours of NATE Continuing Education Credits are available for technicians with a AC or Heat Pump specialty.  In order to receive credit or a certificate of completion, techs must pass the quizzes with a 70% score or greater.


Great technicians don’t just happen, they must be trained.
