HVAC enjoys the widest use of skills including plumbing, electrical, physics, and daily and hourly troubleshooting.

Plumbing is condensate management, sweating/ brazing refrigerant and gas lines, electrical, well, how does a blower run and how is the conditioning cycle controlled, physics involving airflow and pressures and every service call something is broke and you have to figure out what it is!

This is my opinion from personal experience doing mechanical trade work.

Be specific. Pick one trade and learn all you can. Electrician, plumber, welder, etc...

Good tradesmen will be in demand of a long, long time.

I’m HVAC certified. Have been for almost 10 years first 2-3 years is shitty low pay but if you keep a positive attitude and willingness to learn there is good money and many uses for skills like those. I started in hotels plunging shit started painting then drywall then plumbing then electrical. Shit now I’m pretty much ver eses in all technical aspects kitchen equip everything. The key point I guess I’m getting at is take a shitty job and do everything to the best you can if you don’t know take pride in learning the right way and ask questions. School didn’t really teach me working with old timers some nice and some grumpy as hell they could all teach you something.

GAfkgRED, i agree with you somewhat on being specific, but i also do think when you are starting the trades it is good sometimes to start with one and get on the jobsites to see how they all work together and see if one of them is what you would rather do. Kind of like going to college an dchangeing your major...... I have spent a lot of my life in the trades and the work is satisfying and you get paid well after putting in your time to become a journeyman, and you are correct they will definately be in demand!!!
