Class Is 8 Hours credit
The course is design to increase the awareness of Master contractors and Journeyman of the importance of new refrigerates the HFC which have replaced all of the old
CFC and HCFC which were the old R 12, R22, R502 and many other lesser known The new oil used with HFC as a great problem that this program is design to introduce to the participants
