Most people underestimate the breadth of knowledge required to be a good technician. Seasoned veterans of HVAC machines have had 20-30 years to learn everything they need to know. Their knowledge is vast, but as innovation continues to push every machine into a new high-tech space, these veterans will have to adjust quickly.
Humans simply can’t absorb new processes as fast as they become available. And, newer recruits have even less time to learn old procedures and new techniques at the same time. However, machines have that capability. They can remember infinitely more than humans, and their use allows even the newest recruit to arrive at a job site with the experience of thousands of technicians alongside him.
