Is there one job in your business where AI is actually worth trying — and if so, which one?

That is the only question this answers. You finish with a written, dated answer and the reasoning behind it.

Two hours, across one day and a night. You write down where your week actually goes — from your records, not your memory — read nine straight judgements about HVAC work, score your own list, run the top three past a safety check, and write one page you keep.

If you cannot spare a whole evening, there is a twenty-minute route in the opening pages, and the refrigerant section stands on its own.
