Heating, Air Conditioning, Fridge, HVAC/A/C techs habits
Do A/C techs routinely leave service dates and notes inside units where the homeowner would not see them but another tech would?
I want a second opinion but I am wondering if there is information inside the unit that will negatively affect such opinion.
If we're working on something that we do on a regular basis-you bet! Usually its tech stuff i.e. wiring changes, refrigerant type, past repair(s), etc.
I'd never waste time leaving a note as to the customer/personal-unless as a warning about the equipment.
