I can still recall back to this time when I was young, when our parents were fighting, and l acquired that our father tried to service the Heating & A/C system on her own, and my mother was screaming at him because she told him to hire the professional Heating & A/C contractor to take care of everything; Evidently, the warranty on the Heating & A/C system was now void because she tried to work on it himself & she ended up totally damaging the Heating & A/C system so it would no longer work, however they were going to have to spend money on a big amount of cold hard cash to have it fixed because there was no longer a valid warranty. Back when the Heating & A/C worker came to work on the thing, she proposed that they get a new Heating & A/C unit due to the fact that the injure to the Heating & A/C was easily expansive. She said she could service it but it was going to cost a small fortune & they would be better off getting a new Heating & A/C system altogether. This was a very tough lesson for our father & she ended up going for the new Heating & A/C system. The new Heating & A/C unit was at least more energy efficient & she tried to throw that argument out there to our mother, but the argument was pretty weak. I even told my sweet mother not to be so hard on our dad because I said that nobody is great. My parents both loved that coming from me, & I think it helped to calm them down. I just hoped that after that experience, I didn’t get in trouble over things that seemed to be stupid in comparison.
