Yes, the tech should use a leak detector.

Anything mechanical will wear out and break. Leaks happen from seals drying
out, mechanical loosening from vibration, joints getting bumped into, etc.
While it can take some time to find the leak, he should have at least made a
quick check of the obvious easy to reach places as a start.

"seals drying out"? "mechanical loosening from vibration"?

Not in residential split systems. They are hermetically sealed and have
brazed linesets.

Not every brazed joint is a perfect joint.

Not even wrong. All split systems have line taps or service valves
(Except for the extremely rare exception). Most split systems also have
compression or flare fittings as well. If you don't know HVAC then let
the HVAC professionals here do the answering, because you apparently
don't have a clue about HVAC. You could do more harm than good by
posting wildly incorrect information.

It is much cheaper to just have the freon 'topped off' every 6
years. Forget the leak until it requires rejuicing every year.
