My son is area of a group of high school seniors participating in a several week beach new home building boot camp… It’s a way for teens to learn all about the nuts & bolts of building a home, but the idea is that the students have exposure to skill sets that could become a profession, plus expertise that will help them as future beach new home clients. The kids learn to frame, shingle, tile & plaster. They also get to shadow electricians, plumbers & heating & cooling techs. My son enjoys the program. It’s captured his imagination in a way only video games have in the past, however he says he likes working with the tradesmen the most. He asks a lot of questions about our new 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 Heating & Air Conditioning professional after graduation. It would entail cleaning oil furnaces, servicing air conditioner units & assisting with the installation of media air cleaners. He would also need to take an Heating & Air Conditioning certification course at the community university at some point, then one piece of component he’s learning about now at the boot camp is the heat exchanger. My son explained to me that heat exchangers task on both the heating & the cooling of a home, which was news to me. He then said, with fantastic confidence, that a heat exchanger transfers thermal energy from one medium to another. I’ve never heard our child talk about anything so smart! He said that the less energy needed to cool or heat a building, means a more energy efficient Heating & Air Conditioning system. Heat exchangers do the heavy lifting for you. I am ecstatic our son is so interested in something that could become a work for him.
