Hey guys and gals, name is Alex I'm 23 years old from Huntsville, Alabama. I've been doing hvac work for 4 years now. I work hvac maintenance. I know a little about residential but most of my work has been with steam absorbtion chillers, centrifugal chillers. Big chill water systems but I do work on a few walk in coolers and freezers. I don't know it all by any means but will help anyone with any questions that need advice. I'm an "apprentice" but will be topping out as a journeyman in less than a month. Can't wait to learn alot more from this forum!!
