After talking to Grandpa, I knew I had a lot to learn about Heating plus Air Conditioning. I thought it was just heating, ventilation plus a/c, however it was so much more than that. Air conditioning was one of the most important tasks for people to have when in a submarine or a ship… Since you couldn’t get fresh air into the cabins or in the bowels of the ship you had to have someone keeping the air purification plan running. There had to be a way to circulate the air throughout the entire ship or submarine plus keep the air fresh as it circulated. The Heating plus Air Conditioning serviceman was given special classes so they could make sure this was always happening. They had to guess how to isolate certain rooms if there was a concern plus how to keep the temperatures evenly regulated, then when in a submarine or ship, there were always going to be section that were colder because they were further under water, plus you needed to be aware fo this. He said it wasn’t just studying how to maintenance an Heating plus Air Conditioning system, however you had to guess how it worked plus why it worked the way it did. I was constantly changing my mind about what task I wanted to do as an Heating plus Air Conditioning serviceman. I was telling my friends about Grandpa plus Jake told myself and others he sounded cool, however what did that have to do with my being an Heating plus Air Conditioning serviceman. I told him I had recently signed up to go into the Navy. I wanted to be a Naval Heating plus Air Conditioning serviceman.
