For the people working in this field what advice would you give to someone thinking about getting in the HVAC field?

So i was considering this field but i hear every now and then people saying that they wouldn't do it again because of how their bodies turn out and would rather do somthing like being an electrician .but i also hear that it is a dirty job im mentioning this because i was a cna for a bit ( washing elderly ,cleaning and changing them) and i was wondering does it get worse then that ,it probably doesnt but its best to ask . Also if anyone could take a look at my community college's program i would appreciate it http://catalog.prairiestate.edu/preview_program.php?catoid=4&poid=658&returnto=234
