Hello everyone. My name is Paul. I just recently finished my HVAC training at the Peterson school in Woburn, MA. I got my EPA HVAC 608 certification as well. I've visited this website in the past. However, due to the posting rules, I haven't been able to contribute. My focus is on residential A/C and commercial refrigeration, especially drink coolers and food freezers. I'm hoping that I can get my post count up and become a pro member soon so I can contribute and learn more from the pros here. Thanks everyone.
