Best Instructional DVD for HVAC
I am a MD state apprentice. The technical training center I attend is updating the labs and facility so no classes are offered through DEC and Jan. I want to continue learning so I will be ready in late Jan for the next class, can anyone suggest any learning software which is helpful? I looked into RSES for there upcoming events ,but apparently my local branches are not very active. I thought about using Nate study software ,but someone told me you would not be ready for Nate unless you were in the industry 3 years? I have been an apprentice for 7-8 months.
