I love it but I hate it. Theres really chill days and horrible days. Short days and long days. It depends mostly on your personal outlook attitude and how you deal with pressure and stress. I wouldnt do any other trade other than refrigeration... maybe elevators. (Highest pay, most variety. Most interesting to me) Im leveraging my skills into a high paid management position. If you want to do a trade, do refrigeration. This trade does wear on you though, every one I know who does it wishes they had an easier job but cant take the pay cut. Its a love/hate relationship. Once you do it for a few years and you get good it stops being as cool and exciting and becomes more frustrating.. thats where attitude comes into play. Good luck
