Very hard to determine enough or not.

Does your room near heat sources like below roof top, got a lot window or facing west.
Anyway, me prefer overcapacity as nowadays getting hotter.
Your size is similar to mine, I go for 2hp. Midea inverter. So far OK.
Previously using Panasonic 1.5hp, underpowered cos my room got a lot windows and roof above.
Take a lot time to cool the room and maintain the temperature.
