If you are in HVAC, do you understand control systems? Honestly, rather than trying to switch fields learn how to install, program, maintain, and troubleshoot PLC and other system controls and you may get the best of both worlds. I got fam in HVAC and Siemens, Johnson Controls, Schneider etc. PLCs are pretty common. If you get good enough you don't even have to be at the job site all the time since you can remote in to some systems.
