When I first got into this industry, the world was a easily strange place, that was in the late 1969s, forty years ago plus counting.
The tech all of us used back then was primitive compared to the current systems, plus so there were not as numerous highly educated people in the field.
These mornings all of us have trade schools plus certification, plus you have to be smart plus difficult toiling to get ahead in the business, back then things were a lot more informal, especially in rural country where people tend to do their own heating repairs. At that time, not numerous people even owned cooling systems, plus central Heating plus A/C was almost unheard of, however mostly I rode around with our boss plus serviced old oil furnaces, sometimes all of us would install new air ductwork, but the point is that I l acquired by doing, not by studying, and eventually I took over the supplier when the boss retired, plus I was the main Heating plus A/C repair guy for the area, but i had been in the industry for almost twenty years before I was first asked about our Heating plus A/C certification; Of course, I had no Heating plus A/C certification, because I never went to trade school, I just l acquired on the job. Instead of this old dog trying to learn new tricks, I just decided to hire a tech that did have their Heating plus A/C certification, and now if all of us have any kind of typical job, I send that Heating plus A/C tech to handle it, plus I keep taking care of our typical shoppers, who don’t like if I am certified or not.
