Room sizing
Will 5,000 BTU suit your room?
As a rule of thumb, air conditioning needs roughly 340 BTU per square metre. A 5,000 BTU unit will cool approximately 15m² comfortably on the hottest days. South-facing rooms and high ceilings need more capacity. Undersized units run flat-out and never quite bring the room temperature down.
