Hey guys just wanted to introduce myself i plan to use this site a lot. Im 19 years old and just about to finish at ATI las vegas for my hvac/r certification. ive delved into heat pumps, gas furnaces, commercial and residential units so far and ive got a knack for it of course with the economy finding a job even here in vegas where its 85 degrees or high 9 months out of the year finding a entry level job has been hard. but im glad i found this site and maybe some of you hvac veterans can give me some pointers!
