The CompTIA+ certification will serve you well if you have the experience to also show for it.
I took an IT Essentials course back in high school that practically prepared you for that test. It was a great course, but I'm weary of reimaging hard drives and installing fresh OS's outside of Mac.
Now, without getting into a debate about college or schooling in general as a requirement to get a job, experience will be your best friend here. You need to decide what is comfortable for you, and understand that some things may deter you, but do your best and overcome as many fears as possible. It'll serve you well.
In terms of experience, the best thing I can suggest as a computer science major and coming from a 4-year university is that school provides endless options for internships and hands-on experience. Depending on the college (university or otherwise), the quality of the program will also determine how much you will bring to the table in the field.
So, my recommendation is this.
1. Figure out exactly what you want to do (hardware, software, etc).
2. Decide if you can find education of the same quality at a different facility. It sounds like you don't want to invest money in post-secondary level ed if you can help it, which is understandable.
3. In your sparetime, research, research, research!!!!! Much of the material found in introductory courses can be found online, and in all reality, depending on your experience with computers, you may already possess the knowledge to ace many of the course assignments anyways. That's how it was for me in IT Essentials.
Getting your certificate is one step, but research how you can get hands-on experience. Even if it's not considered an internship, experience is experience and that's all there is to it.
Best,
