What People Are Saying About Our Classes

"Highly Recommend"

Had a technician tell me last year he attended a class on heat exchangers. He went on to tell me how he gained so much knowledge about heat exchangers . I got to attend the class today and wow, these instructors covered a lot of material and were thorough. Highly recommend this class if you have the chance. That includes owners, service technician, installers and service managers.

"Well Worth the Time"

This class is well worth the time. These guys do an excellent job explaining how to find a cracked heat exchanger as well as the best way to approach a customer with the results. I recommend that all business owners send their techs and installers to this class.
