Every trade business has a senior technician who can hear a symptom and name the fault. Owners know how much that person carries, and how much would walk out with them.
Peter Capuciati, chairman and CEO at Bluon, put it this way to The ACHR NEWS in 2023: "You have a 60-year-old tech who knows everything, and he retires."
What Bluon did
Bluon had been transcribing its tech support calls for years. It used transcripts of 50,000 calls, data gathered over the last three or four years, to train MasterMechanic, a generative AI app that gives HVAC technicians step-by-step answers in plain language. It launched in late August 2023 and was in beta through October 31, 2023.
An HVAC expert built a 400-point questionnaire to grade it. As reported by Bluon, the first graded version scored 82%, and after optimization it answers HVAC troubleshooting questions with 96% accuracy on that test. Bluon's tech support team keeps updating it. The figures are company-reported, measured on Bluon's own questionnaire.
What it already gives the business
Bluon turned answers its experts had already given into a resource any technician can use on the job. Capuciati: "Now every new tech can have a mentor they can lean on, and they don't feel stupid for calling the service manager."
Adam Curry, senior vice president at Bluon, describes the base the team built on: "We have, like, the best data source in the HVAC industry."
The ExValu perspective, a hypothesis
Where a Company Brain could take it next
Bluon offers its know-how to contractors. A contractor could apply the same idea inside the business: record and structure the answers its own senior technicians give, along with the local equipment and customer history only they know.
A Company Brain could keep those answers current and show who approved them, so the best technician's judgment reaches every van. That is our hypothesis, and the product may have changed since 2023.
What an owner and a buyer would look for
The owner can track calls to the service manager per technician, first-visit fix rates and how quickly new hires work alone.
A buyer wants to see that troubleshooting know-how lives in a tested system with an accuracy check, so a retirement does not take it away. If you record calls, tell callers, define the purpose and set a retention period.
