The room size ( or square footage ) that a 9000 btu system can cover is up to 400 sqft in standard conditions ( i.e. 8 ft ceilings, decent insulation, closed room / not an open floor plan, etc. ). These units are great for small additions, workshops, shed conversions, small garages, or even a game / media room that your central system just can't keep up with unless it freezes out the rest of the house and empties your wallet in the process.
