Over the years I've had several local HVAC companies provide seasonal maintenance of the heat pumps and propane furnace in my house. It seems that every technician–even within the same company–does different things. One tested a capacitor. Another hosed out the compressors outside. Some open the air handler up and vacuum it. They all clean the burners, check/clean the filters, and make sure the condensation drain is clear. What should they be doing each visit?

Your list is pretty good. Check/clean flame, filters, condensation drain and coils. I would also listen for abnormal noise and check both cooling and heating performance by measuring the indoor and outdoor temperature splits. I would not go measuring capacitors unless I suspected a failure.
