Hey My name is Al and im a U.S Marine who is getting out of the Corps in a couple of weeks. My Dad is a commercial refrigeration mechanic and i am going to TCI College Of Technology for HVAC/R trade. Before i joined the Corps my dad always took me on the job with him so i surely remember alot but then i enlisted in to the infantry and been away from the trade for the past 5 years. My question is do i need any startup tools, or any helpful books i should read? Im mostly looking to do commercial refrigeration in NY and just follow my dads foot steps, he is extremely helpful but doesn't know anything about these trade schools... Just thought i would give this site a try, Thank you very much!
