Make them get a permit and follow the manufactures instructions. The HVAC inspector should not involve himself in any other issues. Secondly on the work performed by the HVAC contractor has to meet the current NEC. So the example of the plugs having to be GFCI is incorrect. They would be accepted as is.
If any new plugs are installed in unfinished basement they could have to be GFCI protected unless they are specific to an appliance...example washing machine plugs are not GFCI protected, or sump pumps, or a freezer.
Demand they take the permit. I'm surprised that some of you have suggested that the H/O not worry about the permit were it's required.
RoboTech? Why would you expect the customer to trust the contractor that hasn't followed manufactures specs. In our area the inspector will insure that Man spec are followed. To me that is a good thing. Not once in over 30 years hae I seen an inspector deal with any other issue than the HVAC system.
