The more I read about the HVAC/R and meet people who currently work in the field, I do not know if I want to spend my time and money to pursue this trade. there are a couple of people in my current refrigeration class who work in the trade and they are complete retards. I can not believe that these guys are working in the field and installing residential systems in homes. I feel sorry for the home owner who gets these two idiots. Other refrigeration classes that I have taken had some techs in the class and they were idiots also. One of my teachers who taught one of my classes told us how to make extra money ( if you know what I mean). After my teacher told the class about these crooked things, I was amazed how some of my fellow students also informed the class on how to make "extra" money by doing crooked things to peoples A/C units. Please tell me that the trade that I am currently trying to learn is not filled with these types of people?
