Now I'm wondering which jurisdiction you're talking about. I live in California
in a home which was finalized in 2019. As I'm the first owner, I was there when
the inspector went up into the attic and checked my HVAC. My HVAC has a plug in
power cord running into a regular household socket (all in the attic). The 
inspector didn't say a word about it and issued the occupancy permit.

My electrically powered oven is hardwired, but I guess that's because it requires
two 50amp breakers?
