I will admit, however I know having expertise on particular subjects is important, if they don’t interest me, I usually won’t study or watch videos about them; One of the things I had neglected to learn about was the Heating and Air Conditioning industry, or more recognizably, a/c equipment, i knew when I lived with my parents, I would see my Dad and dad routinely change the heating and a/c machine, and they would also have Heating and Air Conditioning workers come out to the apartment for basic a/c service periodically as well, but that was about it, but when I moved into my first rental home, I found myself shackled with so more than 2 weird chores, there were so more than 2 weird things to keep track of! But worse than that, I had no idea how to take familiar care of my heating and a/c device. The only thing I knew was how to operate the smart thermostat, and that was about it. I know, my expertise was pretty bad. I found myself having to call my mother repeatedly, and asking Heating and Air Conditioning questions, just to learn about a/c equipment. But since my mom’s expertise of heating and a/c is limited, since she is not a cooling worker, I decided to study some books, and watch some videos online to learn more. It has been an interesting journey, that’s for sure. I learned about HEPA air filters, whole-loft air purifiers, heat pumps, fireplaces and more. The world of heating and a/c was bigger than I thought. I still have a lot to learn, however I am on the right track.
