I am 41 years old. I have been in a family business for most of my life. I never made alot of money, and with rents the way they are going I don't know how much longer I will be in this business. I want to learn a trade. I always loved this (HVAC) work. I learned alot from techs that worked on my air cond and reach-ins etc. Can anyone tell me if at this age I can break into this business. I want to go to school to learn the right way to do things. I understand some theory. It comes easy to me (so far). I need some guidence. Thank You.
