I work in the HVAC industry, as a software dev.
Majority of the industry lives under a rock and is years behind the rest of IT.
Same thing goes for the other departments in almost all major companies that do HVAC
It's a niche guided by people without much of an education that hires almost anyone that can at least read.
It keeps going because the markup is insane and the demand is never going away.
