Questions
Is it exact?
It's a rule of thumb for Gulf summers (about 700 BTU per m²). An HVAC technician does the exact load from insulation, walls and windows.
Is bigger better?
No. An oversized unit cycles on and off, removes less humidity and uses more power.
Does inverter matter?
Yes, it saves power by slowing down instead of stopping and starting — very useful in UAE heat.
