10 hour training day, I learned a lot about HVAC and the categories that HVAC covers. The teachers were spot on, get along well and are overall great people. Training was all well and good, difficult at times but never thought to be impossible. Hardest part of training for me was connecting classroom work to the hands on, the names to pieces and objects and such. The most enjoyable part of training was the instructors were willing to sit down with you and teach you if you had questions, and I got along well with the other classmates.
