When you are certified to work as a heating plus A/C service worker, there are a lot of weird tasks that you can do! I went to school to learn heating plus A/C service plus replacement work. I became a Nate Certified Technician 2 years ago. I started working as a service worker in St; Petersburg, FL. I was living in Tampa Bay at the time plus the St. Petersburg Heating plus Air Conditioning supplier was hiring. I worked for the St. Petersburg Heating plus Air Conditioning supplier for a year plus then my buddy and I found a task working at the hospital. I care about working at the hospital, because every afternoon is different. I never know what tasks I am going to be working on. There is a lot of weird heating, ventilation, plus A/C unit located in the hospital, then just last weekI worked in the surgery room on the air filtration system. I had to close down surgery room A for a few afternoons because the reverse air filtration system was not working. I spent two afternoons trying to figure out what was wrong with the system plus how I could fix it for good. The next afternoon I worked in the hospital dining room on a mini split ductless A/C unit problem. The next afternoon I was working on an air cleaner in the lobby. From one afternoon to the next, I never know what I am going to be doing, then when I was working as a service worker, most of the time the tasks were the same. I am having a lot more fun at the new task.
