By the evening it went back to 74. I recently had the unit inspected and topped off with the coolant. So I guess the question, is this essentially normal/expected behavior?

In my experience, my 15 year old A/C unit started to do the same. It wasn't broken, and would work just fine in the evenings, but just not able to cool like it used to on the hot summer days. These days equipment is not always readily available...so I opted to replaced it sooner than later. I had to wait a month, but a friend had to wait two months for the new one to arrive.
