If the capacity plate was missing, illegable or not visible at the exterior of the unit, this limitation should have been noted in the report as an item needing follow-up by an HVAC contractor, but it would have been beyond the scope of a home inspection to research the equipments power requirements - which is tough to do without a model number.
If the conductor size at the breaker was adequate for breaker but insufficient for the equipment served, depends on whether the capacity plate was available. If so, the undersized conductors should have been noted. If not, a really good inspector should still have caught an *obvious* conductor/load mismatch for follow-up, but absent the capacity plate this would have been just a "guess" as there would have been no way to be sure without researching the equipment.
