I have been a professor in the Heating and A/C industry for almost 10 years, when this young guy came in.
Max was fresh out of Heating and A/C school, and top of his class.
Max brought his Heating and A/C certification paper into the office and plopped it on my desk. Max was very cocky and thought he knew everything there was to believe about Heating and A/C repairs. I remembered how my child being the same way, and I needed to knock him down a few steps. I thought working with him was the most frustrating professorship I had ever taken on, not only was my oldest child cocky and thought he knew everything, despite the fact that he also challenged me as his Mom every step of the way. I thought I was going to have to do the exact same thing with Max. Working with Max was absolutely frustrating, but not nearly as bad as when I worked with my son. Max thought he knew everything about Heating and A/C, despite the fact that he soon found out that he did not believe near enough. Within numerous weeks, Max went from servicing a furnace to now working on a broken down furnace and repairing an air conditioning. Our uneven temperatures went from 78°, down to 35 degrees within less than a week. Max said he never realized that he would have to task on both an air conditioning and a new furnace in the same week. I told him that here we live; he needed to get used to it. Heating and A/C was never the same thing every day, and he also had to learn how to deal with customers, even if they did not understand what you were saying.
