Frigidaire FAH085N1T cools OK but room is "clammy." Is the unit too large? Room is 138 sq. ft, 8 ft. high. Various calculator sites recommend between 6000 and 9000 BTU. This one is 8000. Is it too big? What else could cause inadequate dehumidifying?

that is a 10000 btu unit and a good rule of thumb to go by when 'sizing' a unit is 12000 btu for every 600 sq ft of cooling space (if the place is well insulated) or 400 sq ft (if not well insulated).
So, you have a 10000 btu unit which is 5/6th of 12000 btu - so - can reasonably expect that unit to cool approximately 500 sq feet.
In other words the room it's in now could be only - say - 300 sq feet (and well insulated) - in which case the AC unit is cooling it - well.
However, if you try to cool a 800 sq ft room - it will not work as well.
Hope this has helped.
Assuming the unit is 'cooling' but not cooling it 'well,' I would think the unit is too small.
NOTE: 2000 Btu for every 100 sq ft of cooling space if the room is well insulated. If not - then 2000 btu for every 66 sq ft.
For example - a 12000 btu AC unit should cool 600 sq feet of cooling space if well insulated.
400 sq feet if not well insulated.
hope this has helped.
The AC your landlord installed is rated at 8000 btu which is way too small for 900 sq ft. You need at least a 15000 Btu Air conditioner and a 'well insulated' house to be cool.
A good rule of thumb in the AC business says you need 1 ton (12000 btu) of Air conditioning for every 600 sq feet (if the house is well insulated) - if not - then you will need 1 ton (12000 btu) for every 400 sq feet.
So, if you have 900 sq feet and the house is well insulated you should have at least a 15000 btu unit.
If it's not well insulated you will need 24,000 btu.
Wash out outside coil from time to time.This is the most over looked part of window units. Take care not to spray water directly into fan motor. If not real humid in house check temp coming out of ac inside and make sure filter and coil are clean. run on high speed and the air should have good force. 20 to 30 degree temp drop of room temp should be about right. Much depend on outside temp and humidity and indoor humidity plus insulation factor of area. How many people are in the area and if you keep unit on day and night .
To be honest with you this is a good and a bad thing. The bad thing is that it is spitting water into the room. The good thing is that the unit is running Great. The amount of humidity it is removing. is greater and faster than it can run down and off the coil. See if there is any possible way to deflect the water. i would recommend trying to attach a piece of screen door material. It will likely keep the water from going through it.
An 11'500 btu Is appr. 1 ton of cooling capacity or enough to cool approximatly 450 sq ft of floor area. Be sure to read the instructions of course and be sure that all the packaging material was removed that may be restricting airflow. On high you should be able to easily feel the air blowing 10-15 ft from the unit and the air should be dropping about 15- 20 degrees when it exits the unit. So if the room temperature is 85 degrees the air exiting the unit should be around 65 -70. The amount of time it takes to cool the entire room depends on how big the room is and how much and the intensity of the heat infiltrating the room and the number and heat output of appliances and people in the room. Hope this helps you out GL!
