I just heard back from the guy. He stated:

Just got your email forwarded to me for some reason the Angie's List email system does not always forward. Attached is a copy of the Big deal promotion that you bought. He did perform the items on the list, and found you to be low on refrigerant. All other items are within specifications. Let me know if you want us to come and re-charge the system

"Calibrating and leveling thermostat

Cleaning filters as needed

Lubricating and inspecting bearings for wear

Monitoring operating pressures of refrigerant

Inspecting safety devices for proper operation

I think most of us are still curious as to whether you had an
actual problem that lead to this checkup or was it working?
I would think with 8 pounds of R22 missing, it likely would

how many tons, but 8 pounds sounds like it could be all of it
for a typical residential system.
