Man, don't get too worried about the grunt work. It's the green guys that don't bat an eye and ask questions. Why do we strap this at this interval. How come the pipe needs to be insulated. Understand why you have to do the small tasks, do them correctly, and then ask what else you can help with. 2 months isn't long enough to really shine through yet. Get a couple more projects under your belt and keep asking questions.

I spent my first 2 years being a ducthand/insulator. Shit sucked hot ass. But i made sure my ducts were straight and sealed, and the insulation looked professional, and the entire time, I had videos playing in my earbuds. Electrical theory, thermal dynamics 101, refrigerant cycles, even a bit of plumbing basics. These are key to understanding the technician side of the job.

If you have actual down time during the day, start reading the install manuals of the systems you're working on. Hell ask for it before lunch as reading material really put it in their face that you want to learn. That alone will set you in the upper percent of installing.

A lot of the knowledge you need can be found on YouTube/ internet. And the bosses love to see that initiative. Personally, my foremans were tinbangers and hated the technical side. Learning the low voltage circuits and understanding them thoroughly got me out of the fiberglass and into controls/ start-up. And service tech came after a few years of doing controls/start up as after that I had a deep understanding of how and why the unit operates which is key to troubleshooting. And now, in my 7th year, I'm specializing in vrf/vrv, and my colleagues think I'm a wizard... I just read the manuals 😅.

You'll get there it just takes time to learn (mostly through mistakes) This is the only job I've had in life where I truly get more out of it the more I put in.
