At some point in life, I worked for a high-end HVAC company. My role was in the factory, where I helped manufacture parts for the most common brands in the industry. I worked there for almost ten years before the company shut down due to unavoidable circumstances. When I lost my job, I got into alcohol and drugs. I was in this abyss of darkness for three years, every year worse than the last. It took a near-death experience by one of my friends to realize how precious life was and that I had no right to live my life like I was. After three months in rehab, I got a job as a doorman at a great building. I would chat with one of the tenants and tell him about my experiences as an HVAC technician. He was always interested in everything about HVAC systems, as he had worked in that industry for three years before he landed a corporate job. He consistently inquired about the new HVAC technology as he was interested in getting quality heating for his young family and learning more about heating. One time, he met me at the door very excitedly. He told me about the new HVAC equipment he had just purchased for his home. Mike had also upgraded his thermostat. I kept hoping to be an HVAC repairman offering heat pump service and furnace/heater repair because it was something I loved doing. Mike asked me to do all the HVAC maintenance and replace the furnace filter to earn extra money, and I took him up on the offer. It went on for a while. He referred me to his friends, and I installed a furnace at one of the homes. I then advised another to opt for a heat pump to help with indoor comfort. I am three years sober and back to my old profession.
