I only hire licensed HVAC companies and workers
My sister is constantly trying to fix things around her house without getting outside help. We both learned a lot from a father who works in the trades. He might be an electrician by profession, but he is also a skilled carpenter, plumber, roofer, and general handyman. He taught us everything from building wooden shelves to changing the oil in our vehicles. I realize in retrospect how lucky I was to have a father who always had so many valuable skills to teach his children. Many of my friends had unskilled parents, while others were missing one or both of their parents entirely. This is how it is with cooking as well, because our mother is a retired sous chef. My sister and I also take for granted the fact that we learned cooking at a young age as well. But, you can do a lot less damage by taking risks cooking, assuming you leave out mishandling meat and giving yourself food poisoning. My sister is constantly embarking on projects that are far beyond her expertise. I told her to hire a licensed HVAC worker to maintain her air conditioner and furnace. Instead, she claims that she knows enough about air conditioners to do everything herself. Even if I learned the trade from a real technician, I would never compare myself to the licensed HVAC companies that I have worked with over the years. These people are trained to handle these concerns on an hourly basis. You can’t replace the years of experience and wisdom that a verteran HVAC technician has with the heating and cooling industry and the machines on the market.
