9,000 BTU would work. 12,000 BTU may be a better choice because you are at the limit.

Thank you all for your responses so far.
Adnj the thing is, I currently have a 13000btu unit in a similar sized room facing the sun in the evening.
What ends up happening is the temperature reaches its set point (say 24C), the compressor then shuts off, but the room still has a lot of humidity in it. (yes I measure the humidity with a small hygrometer). The compressor then has to cycle on and off a couple more times before the humidity drips to a comfortable level.
When I looked online to see the cause of this, I saw it is possible that I may have an ac with too much capacity - so the unit cooling the room faster than it could remove the humidity. That's why I resorted to using various online ac btu calculators and they all mostly gave a capacity closer to 9000btu.

Older odd sized units would have been toshiba and the likes.
There is the possibility his compressor seals are worn, unit not properly serviced, fan bearing failing or fan motor failing or fan capacitor failing.
Disregard all the online calculators you see. Use 12x12 for every 12000 btu. Eastern side or downstairs, downsize by about 1/3.
West side or upstairs where sun blazing, upside by 1/3.
But not all units are equal. Then there is location and ambients to factor in.
Inverter types are discussed in detail in the thread and on my page.
I was seriously reconsidering my trade with stress from old illiterate backward idiots I call parents under pressure to "find a job". And had a small surgery done recently.
Is customers and companies that refusing to let me quit. Was even considering just leaving and selling off everything as the opportunity presented itself. The change will be hard and tedious but might have better peace of mind in another country.carluva wrote:I'm surprised nervewrecker hasn't bounced in this chat as yet.
