College Degree Pros & Cons (Engineering)
1. Can say you have a degree.
2. Can take 8 hour state exams and say you are now an "engineer-in-training"
3. Can take another 1-2 day exam after 2 years of working under someone, just so you can legally call yourself an engineer.
1. Overqualified for minimum wage jobs, so no one will even waste the time to interview you.
2. Under-qualified for all jobs that you actually want because you don't have experience.
3. Thousands, tens of thousands, or hundred of thousands in college debt.
4. End up working under an engineer for for two years, making barely enough to live on your own.
5. Probably end up living with parents, have 6 roommates, or sleep in the living room to save money.
6. Work long hours, doesn't matter if you are salaried or hourly, no one will pay you extra.
But yeah I guess if you really want to get more background in HVAC, you can be a mechanical engineer. The engineering classes might actually seem more relevant since you see the theory in action.
