This class is also known as “The Manual D and J Class”. This class is REQUIRED as a pre-requisite to apply for your Conditioned Air License.

Documentation should include the number of hours of classroom or lab time for each topic. The following are the minimum course requirements: Applicants for a Restricted (Class 1) License must show that the course on ACCA Manual J, is a minimum of 8 hours; ACCA Manual D a minimum of 4 hours and an additional 4 hours of testing and/or practice of the principles in the classroom, for a minimum of 16 total hours of classroom time.
