My child is in a group of high university seniors participating in a multiple month home building boot camp, then it’s a way for teens to learn all about the nuts and bolts of building a home, however the idea is that the students have exposure to skill sets that could become a profession, plus expertise that will help them as future home customers. The kids learn to frame, shingle, tile and plaster. They also get to shadow electricians, plumbers and heating and cooling techs. My child enjoys the program. It’s captured his imagination in a way only video games have in the past, however he says he enjoys finally working with the tradesmen the most. He asks a lot of questions about our home now. I’ve even caught him with a flashlight looking around the utility room in the basement. He’s considering an apprenticeship with an established HVAC serviceman after graduation. It would entail cleaning oil furnaces, servicing air conditioning units and assisting with the upgrade of air purification systems. He would also need to take an HVAC certification course at the community university at some point, but one piece of component he’s reading about now at the boot camp is the heat exchanger. My child explained to me that heat exchangers job on both the heating and the cooling of a home, which was news to me. He then said, with great confidence, that a heat exchanger transfers thermal energy from a single medium to another. I’ve never heard my kid talk about anything so expertiseably. He said that the less energy needed to cool or heat a building, means a more energy efficient HVAC system. Heat exchangers do the heavy lifting for you. I am ecstatic my child is so interested in something that could become a job for him.
