I have been working for an HVAC company for over 20 years now and have mastered almost every aspect of air conditioners, furnaces, and boilers you can think of.
Everyone at work respects me and if they have any questions about how to fix an HVAC unit they come to me.
Recently, our HVAC company hired a new recrewt who was straight out of college, and he thought he knew everything there is to know about HVAC units just because he had read about them in an HVAC textbook. A lot of the HVAC technicians who have been working here for a long time were getting really frustrated with this kid’s cockyness, and they asked me to take him along on one of my HVAC jobs and show him how little he really knows about air conditioners and furnaces. I decided to listen to them and took the kid with me on a job. On our way there he would not shut up about what he had learned about air conditioners in college, he literally thought he knew it all. While I will agree that his kid knew a lot about HVAC units, I wanted to see if he could put his knowledge to good use on this furnace we were on our way to fix. When we arrived at the furnace, I told the kid, using textbook terms, what was wrong with the furnace and then stepped back and told him to fix it. The kid started out good, but soon he had no idea what he was doing and he couldn’t fix the furnace. Out of pity, I came beside him and showed him how to fix the furnace. From that day on the kid no longer bragged about how much he knew about HVAC.
