You can check the delta yourself. Turn on the system, let it run a
while and check the air temp going into the return, compare that to
the output as close to the unit as you can get. If you are getting a
15 degree or more delta,. I might not do anything.
If you are just "low" after 18 years, you may not have a bad enough
leak to justify evacuating the system, charging with nitrogen to test
for leaks and putting in new (recycled) freon at $50 a pound. That is
particularly true if he is not even sure how low it is. Find someone
who will top it up, and check it again next year..

Good idea. Also, check your filter(s) to make sure they are clean.
That the guy says he checked doesn't mean he did.
