HVAC techs trade stories about customers using ChatGPT against them, like the one told the wrong motor was right
One customer's ChatGPT said a new condenser fan motor was wrong and recommended a blower motor instead.
What they did
In a r/HVAC thread that started as a joke about a furnace diagnosis, techs shared run-ins with customers using ChatGPT on the job.
How it went
One tech said a customer had ChatGPT "teach" him while he stood there, and it just repeated what the tech had already said. Another said a customer looked up the condenser fan motor he was installing and ChatGPT called it the wrong part, recommending a blower motor instead. Most techs just let the customer vent, then ask if they still want it fixed.
Worth knowing
It's coming to every service call. Give techs a calm, respectful script, and send photos and readings with every repair so customers trust the evidence over a chatbot.

Messy site notes go in, a clean quote in their format comes out, and invoices finally go out on time.
Customers walk in sure of their diagnosis because ChatGPT told them. Sometimes it's dangerous.

A non-coder with a tech background built tablets, kitchen screens, reservations and inventory, and is honest about the grind.
