I'm very close to finishing all my classes ( HVACR ) at my college and after alot of thought would really like to break into the Commercial Refrigeration aspect of the industry, but have no idea where I should start.

I realize that you have to start at the bottom and work your way up, but what is considered the bottom of the industry? How would I go about picking up a job such as this with no prior expirience?

I'm really excited to get out there and start learning, but need a little guidance on where to start the journey.
