Central Texas A/C and refrigeration is the only way to properly learn HVAC from the ground up. Mr.Eric is a excellent instructor, tough, take it from me.. I KNOW but he walked me through and stayed on top of me. I know so much about this trade,and have confidence in my education. I know my future employer will have confidence in me, since my instructor taught us all right….just study and don’t cheat urself and this program will take you to the next level!!
