For small condos, which A2L charge-limit calculations most often force equipment downsizing or multi-head minisplits?

In small condos, A2L charge limits often mean you either need smaller individual AC units or have to go with multi-zone mini-split systems to keep the amount of refrigerant at a safe level.

In small condos the main limiter is the maximum refrigerant charge per room or connected space under B52, often forcing smaller single-head units or multiple mini-splits to stay under the A2L volume-based limit, especially in bedrooms, bathrooms, or closets where floor-to-ceiling volume is low.
