Median HVAC tech salary is $50k. Is it possible to make $200k or higher? Sure. But the HVAC people pulling down that comp are generally at that level primarily because of their business skills not their HVAC skills.

It’d be like saying you can make a million as a waiter or cook, because of a small business owner who opened a restaurant.
