An HVAC technician is the person you call when your air conditioning dies in a heatwave or your furnace quits in the middle of winter. They show up with a truck full of tools and parts, diagnose the problem, and get your system running again. It's a hands-on job that requires understanding electrical circuits, refrigeration cycles, and airflow. Good ones explain what went wrong and how to prevent it next time.
