Hi everyone! I would like to introduce myself, as I am new to this site. I started out in HVAC/R through the Army. Since then I have been working as a Commercial refrigeration tech(supermarkets) and now Industrial for the past several years-primarily NH3. I live in South Carolina and enjoy all things nature, art, science and good music. Good to meet everyone and I have lots of questions for you and hope to answer some as well.
