In my highschool class, my superb friend and I had a science teacher that decided to perform one of his experiments on the school’s central air conditioner unit, but he put a chemical my superb friend and I made in the air ducts and air filter of the central air conditioner, and the chemical sent into the air ducts system of the entire school.
This chemical made everybody harshly tired.
Another time my teacher used the hydronic boiler to spread a chemical. He mixed it with the water in the hot water boiler boiler, and this proved just as effective as the chemical in the air ducts and air filter of the central air conditioner; Eventually my science teacher got fired, but he inspired me and I fell in love with Heating, Ventilation and A/C units! I started helping my buddy clean his air ducts and he also showed me how to change an air filter in a central air conditioner and a boiler. The more I learned about Heating, Ventilation and A/C, the more I wanted to know! When I became a young adult, I took up an Heating, Ventilation and A/C apprenticeship, plus working part time in a heating and cooling contractor that specializes in heating and cooling equipment. The reason I was so inspired back when I was in highschool is because when my science teacher poisoned the central air conditioner air ducts, they had to call a cooling expert to come and clean out the vents. I was there and got to watch the Heating, Ventilation and A/C professional clean out the air ducts and I then realized that being an Heating, Ventilation and A/C professional was really a entirely cool job!
