I am currently a student, 21 years old, with an interest in pursuing a career in the HVAC industry. I recently found out about a union apprenticeship program offered through my school and decided to go for it. I applied this month and took the math exam achieving a perfect score on the exam. I am now studying for the aptitude test taking place in about a month. Is this a good start? Would you guys recommend I follow through with this opportunity? Lastly, I have ZERO experience in the field and would like to know how I would go about gaining some experience. What about pulling out the Yellow Pages and calling local companies? Do you guys think they will let me work for no pay? I am in it for the hands on experience. Thanks a bunch!
