When my wife passed away two years ago, I felt completely lost. I was living alone, my daughter had just gone off to college. I tried to find hobbies to keep myself busy, but it was hard. When my daughter moved into her first house last month, I knew that I could help her with things around the house. It would certainly keep me busy. It would also give us an opportunity to bond. My daughter was looking forward to our time together as well. But when she called me in the middle of the night crying about her HVAC system, I thought I had signed up for something too intense. But being the good dad I am, I rushed over to her house to look at her HVAC system. I do not know too much about HVAC systems, but thought I could give it a look. Maybe the problem with the HVAC system would be an easy fix. My daughter was a mess when I arrived. I asked her what the problem was. She told me that the HVAC system was making a loud clunking noise. It woke her up in the middle of the night. I had no idea how to fix this particular HVAC issue. I thought the only thing we could do in the meantime was to head back to my house to get some sleep. Then we could call an HVAC company in the morning. My daughter was not happy with this plan as she seemed to think I could fix the HVAC system myself.
