Many have already try to tell you that the issues are too complex
for a "simple" or "common sense" answer. It is too bad that there
are many rip off artists in the residential HVAC service industry.
When you find a good honest one, keep him. Ask for a
recommendation from neighbors, coworkers, church goers, etc.

Simple: at the outdoor unit there will be 2 pipes. One large,
one quite a bit smaller. Check while the unit is running on a hot
day. The large pipe should be quite cold to the touch - depending
on atmospheric conditions it may be sweating a bunch or even
showing a touch of frost. The small pipe will be almost hot
enough to burn your skin. Make sure the coils on the outdoor unit
are clean. If the condensate line is making a steady stream of
water, you know the unit is working, though this is a bit subject
to the relative humidity. If these conditions don't exist, call
for a repairman.

Further diagnosis requires a gauge set, knowledge of refrigerant
types, temperature differential settings, and perhaps add
refrigerant. Most vendors will not sell the refrigerant to non
licensed individuals so the scenario usually dies right there.

So, what is the common sense method to check / measure and
refill (if needed) refrigerant in my backyard AC system?
