Hello everyone I am new to this site. I searched it out since I am a member of contractor talk. But I decided to no longer be a handyman and get into something that has a brighter future to it. I( am going for my associates degree in HVAC/R. I am now finishing up hvac 102 and have gotten a GPA of 3.4 so far in 100 and 102( 100 is ref. fundamentals and 102 is Ref. applications). And am looking forward to troubleshooting systems and the headaches that go with it!!!
