Go to college your major is what you're doing for life. It's not true I knew a philosophy major that was working as an elevator engineer. Do HVAC for 20 years then do something else. It's fine
My resume these days is pretty eclectic and I honestly think it's been a plus. Interviewers like to ask about it and seem genuinely interested in the different things I've done. It demonstrates a pretty wide range of skills and versatility.
