Learning all the basics in Heating and A/C school

When I went to study Heating and A/C at technical school, I thought they taught all the basics. It’s funny how missing 1 single class can make such a tremendous difference. They take it for granted that all of the Heating and A/C students knew how to change air filters in various Heating and A/C systems. They also guess all of us assume where the air filter goes. I knew none of this. No 1 taught myself and others how we should change air filters, let alone where they were located. I went to a job fair at the school and loved talking to the Heating and A/C expert who was there from the local Heating and A/C company. I wanted to find a good job that would be sustainable long into the future. My dad always preached job security, and I could have that with the Heating and A/C company. Once I got into Heating and A/C tech school and started classes, I was realizing how much I didn’t know, and wondering if I was alone in this. I talked to a few other students and found out I wasn’t alone in my ignorance. That didn’t mean that any of us would quit Heating and A/C school, however it made us want to work harder. We teamed up and started a weekly study group; By the end of the Heating and A/C courses, all of us were vying for the top of the class ranking. After taking the Heating and A/C certification class and passing the final exam, I wasn’t number 1, although I was number multiple, and my two best friends placed at number 1, however all of us all got a place with 1 of the local Heating and A/C contactors.
