I agree with George.
The folks on the Code panels are very meticulous about what they write.
I get into regular arguments with Mechanical types who think that the requirement for a receptacle within 25 feet of Heating and Air Conditioning units should apply to all HVAC equipment.
The Code panel wrote it the way that they did to deliberately exclude ventilation (fans) since there is never a need for portable test or service equipment to be plugged in when working on a fan.
Heating and Air Conditioning units have controls and refrigerant lines that need to be evacuated...fan motors do not.
If they are calling for individual GFCI protection on the branch circuit that's exactly what they want there.
