Hey new here first post im from MA. My father has his own hvac business and i have probably about 2 years of on the job experience. I have been trying to figure out what i want to be when i grow up since i graduated high school and im 21 now. I have a decent amount of residential experience. I recently decided id like to become certified and actually be a legitimate tech instead of working towards nothing. So my question is how do i do it? Do i have to become and apprentice? I searched all over google couldn't find anything straightforward enough. Just looking for some steps.
