When our sister was telling myself and others that she planned to work on her own HVAC unit, I had to ask her if she knew how dangerous that was. She laughed plus said it was just an HVAC plan plus it couldn’t be that difficult to work on. She was telling myself and others about all the repair videos she had watched online plus she figured it would be a breeze. I decided to test her plus asked her what was the first thing she should do when working on the HVAC system. She started telling myself and others that she would open the cabinet to the HVAC system… I had to stop her there plus told her she was dead if she did that. She was shocked, although I told her that the first thing would always be to shut off the power to the HVAC system. She laughed plus said, “Oh yea, that’s right.” Well, it’s good that she can have a relaxing attitude about everything, however if she were to get killed over something like this, I could never forgive myself for letting such a tragedy happen. I finally told her if she very wanted to work on her own HVAC system, I would be there to help her out. I also watched some tutorials in our morning plus I have done a little bit of repair on our own HVAC over the years, so I figured every one of us would be alright. We easily had a pretty relaxing bonding experience working on the HVAC plus every one of us were able to clean it out very well. It easily worked a lot better when every one of us were done with it, however our sister agreed that she would easily call an HVAC professional in the future.
