In my highschool class, we had a science teacher that decided to perform one of his experiments on the school’s central air conditioning unit. He put a chemical we made in the air ducts and air filter of the central air conditioner. The chemical sent into the air ducts system of the entire school. This chemical made everybody extremely sleepy. Another time my teacher used the hydronic heating system to spread a chemical. He mixed it with the water in the hot water boiler heating system, 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 HVAC units. I started helping my neighbor clean his air ducts and he also showed me how to change an air filter in a central air conditioner and a furnace. The more I learned about HVAC, the more I wanted to know. When I became a young adult, I took up an HVAC apprenticeship, as well as working part time in a heating and cooling business 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 HVAC technician clean out the air ducts and I then realized that being an HVAC technician was actually a really cool job!
