So I just started doing duct work for this company that hired me to get my foot in the door, but all my guys that I work for say that the "duck men" are different than the actual hvac/r guys. They all seem pretty content where they are at in their job, but to me it's not challenging enough. It's not physically or mentally demanding. I did the same stuff as a maintenance mechanic at Cargill. So my question is, how do you get into the A/C heating side of things or at least some way to get a better foothold in that direction? Any help would be greatly appreciated.
