After I purchased our first house, our dad gave myself and others a couple of books to help with beach cabin repairs.
One of the books was especially about repairs on the AC system.
My current beach cabin Central AC plus a heat pump plus I didn’t believe the first thing about the equipment. My dad worked as a contractor, plus she l received everything that she knows from learning books plus having experience. She never had formal training. I tried learning some of the books, although I found them to be boring. I didn’t use them much at all until I had the first problem in the house. It turned out to be an issue with the central AC. I found the book on repairs plus followed a list inside that included some easy areas I could check for problems. These easy steps included clearing the drain line plus checking for buildup of mold plus dirt, adjusting the air filter, plus checking for problems with the evaporator coils. The handy list pointed myself and others in the right direction plus I realized that the evaporator coils were genuinely dusty plus dirty. They needed to be cleaned. I used an old toothbrush to carefully clean all of the evaporator coils. I l received that trick in the book too. I cleaned the coils, the unit works much more effectively. I called our dad later that night plus I told him the story about the AC unit. Since then, I regularly try to figure out problems on our own before I contact a professional plus spend a lot of money.
