Room sizing
Will 9,000 BTU suit your room?
As a rule of thumb, air conditioning needs roughly 340 BTU per square metre. A 9,000 BTU unit will cool approximately 26m² 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.
