Oh yeah^^^^^^^^^^^^^^^^^^^^^^^^
Go light commercial and work up if you do come into the trade. Residential is very seasonal at least around here.
Many good things about the trade. Good pay, new places all the time. Meet some really neat people. Get to experience things you will never see or do in any other field. So many things to know in this trade. You make your own work once you get established and learn the ropes.
Some bad things....High stress at times. Slow times seasonally and economy driven. Meet some serious A$$hats and nut bags. People want everything for nothing and they want it all yesterday. Everything is your fault.....period. Most Employers will can your a$$ if they catch you doing side work as it is seen as competing.
I have been in this my whole life with brief ventures into other areas but always back to HVAC. Retired last August and my phone still rings with projects. The trade has changed dramatically.
If you want to gab about it PM me and I will give you my insight.
The stress comes when you are under the gun on a project or running refrigeration service. Refer. service is very stressful if you let it be. Traffic getting job to job, trying to find parts and customer does not understand why you do not have an obscure control relay for a foreign made P-tac unit on your truck. Normal stuff.
There are a lot of neat things with the trade as well. Especially when you are a nooby and the learning curve is vertical. Something new and exciting everyday.
If you do the trade school route you will know just enough to get a job and then the crazy starts until you get some experience.
been in the business for 33 years and i have nothing to add as CM has covered about all of it......i have never been unemployed unless i wanted to be....
