For almost a month, I had not felt okay, but it did not feel like anything serious, so I took some self-prescribed medication and continued working at the home services company where I was an HVAC tech. I felt a bit faint on a Monday, but since it was the last call of the day after a furnace installation, I decided to push myself harder. The homeowner had been vague on the phone because, besides her home address, she said she needed heating maintenance, and then the call disconnected. I went there prepared for all the heating repairs, just in case. When I got there, she told me that the heat pump constantly switched itself off. Given that she had one of the best heating devices in the heating industry, I knew something was wrong. The installation at her house seemed fine, but after a thorough inspection, I discovered that the digital thermostat was the problem. It prompted the unit to shut down even after the owner manually switched it on. I also found a leak in the ductwork. Luckily, I had geared up for duct sealing. As I was going up the ladder, I started feeling dizzy. The last thing I remember was the lady calling someone, saying that an HVAC tech had fallen off the ladder and was not waking up, and then everything went black again. I woke up two hours later in a hospital. Over the years, I worked as an HVAC serviceman, having worked on every type of heating technology; this was a first. The doctor said I was very dehydrated and anemic.
