My son wants to be a HVAC professional

My son had been showing a lot of interest in HVAC as his career.  He was soon to graduate from high school, and I was beginning to worry.  He had shown no interest in getting a job or going to college. His interest in HVAC came as a total surprise, but a pleasant surprise.  We had scheduled an appointment to have our air conditioning serviced and my son asked if he could be present when the HVAC technician showed up.  While the tech was going through the servicing of the AC unit, my son stood back and watched. He began to ask questions as to what made the AC cool the air.  The technician was very patient and he answered all of the questions. He also asked where he could go so he could attend classes to become a certified HVAC technicians.  The technician told him about the courses the local college offered in certification for heating, ventilation and air conditioning. He told him it took about eighteen months, or longer if you wanted to specialize.  He also asked what got him so interested in HVAC. He said he had seen us struggling with bills over the years and some of the expense was in the maintenance of the furnace and the air conditioner. He thought that having a HVAC tech in the family would help to eliminate some of the burden on us, and it would give him a good job for life.  He has no idea how proud I was of him at that moment. He was thinking of us and learning that HVAC was a career that wasn’t going away.
