It’s funny because I always used to complain about the high prices of getting correct heating plus A/C repair, and my child used to ask why I didn’t just work on the heating plus A/C device myself even though I explained that I was not a certified professional plus that non-professionals finally working on the device would cause the warranty to be void! From that time, my child said she was going to work on the heating plus A/C for myself and others in the future, and I had such a wonderful laugh when she said that, but she said she was serious! Sure enough, she studied all about heating plus cooling repairs as she was coming up, it became a real interest of hers. She even inspected old portable heating systems plus window A/C units both of us had in the garage. I was meaning to take those to the dump since I thought they would never work again, but she got all those heat plus A/C products finally working again… However, there was no risk of voiding the warranty on those products, so I didn’t see any issue with her finally working on those things. I just told her to be super careful because window A/C units have refrigerant inside plus you don’t want that stuff leaking on you! She studied so many heating plus A/C repair books from the library that she had no issues in the least. She was even giving the heating plus A/C experts advice when they were coming over plus they provided her advice in return. She eventually went to an actual heating plus A/C trade university plus became one of the best heating plus A/C professionals around! The attractive thing is she kept her promise, she works on my heating plus A/C device plus she won’t accept my cash to pay her for the work she puts in!
