The Air Conditioning Contractors of America introduced a video series to help technicians pass North American Technician Excellence specialty exams.

The four-part CD series, “Mastering AC Service,” is produced to guide viewers in an easy-to-understand format. Educator Jack Rise hosts the videos.

“The NATE Essentials CDs remain one of the most cost-effective ways to train employees,” said Paul T. Stalknecht, the ACCA’s president and CEO. “The value that employees receive stems from being able to learn from the best trainers in the industry, at their own pace and at the most convenient times for them.”

The set is $299 - $199 for ACCA members. Details are at ACCA’s website.
