What size unit do I need for my room? Use the following chart to find the appropriate size air conditioner to use:

AREA TO BE COOLED / CAPACITY (BTU/HR)

100 to 150 square feet = 5,000

150 to 250 square feet = 6,000

250 to 300 square feet = 7,000

300 to 350 square feet = 8,000

350 to 400 square feet = 9,000

400 to 450 square feet = 10,000

450 to 550 square feet = 12,000

550 to 700 square feet = 14,000

700 to 1000 square feet = 18,000

If the room is heavily shaded, reduce needed capacity by 10%

If the room receives a lot of direct sun, increase needed capacity by 10%

Add 600 Btu/Hr for each person in the room if there are more than two people

If the unit is for a kitchen, increase the capacity by 4,000-6,000 Btu/Hr.

if this helps please vote me a fix ya

Get rid of the old stuff,too big to be used
Newer unit can't be inside the old sleeve as you call it

Just install the new unit how you see fit, to seal
it up

5000BTU is too small

A 7,200,8,000 or 10,000 BTU is the same size & about
the same price.

Debi, it;s not unusual for an AC unit to turn ON & OFF. Once it reaches the temperature that you have it set ON and holds the temperature for 4 or 5 minutes, it will shut OFF until the room temperature rises above it. Be sure all the doors and windows are closed and no hot air is infiltrating the area.

Also, a 10,000 BTU air conditioner is not designed to handle a large area. Generally, 10,000 BTU's will handle about 3200 Cubic Feet (20' x 20' x 8' = 3200 sq ft) or simply put, 400 square feet. Your A/C unit may be undersized for the area you're trying to cool.

Hope this helped you. Please let me know. Thanks.

Frigidaire AC 10,000 btu-not cooling very well


Make sure the filter is clean. Take the unit outside and get some coil cleaner and cleant the coils. You'll have to remove the casing. Also,rinse it from the inside outwards.

AC was cooling fine. Now, won't cool room even though cool air comes out. Exhaust hose is extremely hot.


Check filter, if you have a 5000BTU unit (small) and it is extremely hot, then it wont work great for a big room. BTU is the rate of what the AC will put out. 5000 BTU is good for a small single room. 10,000 will cool a bigger room and 18,000 btu is meant to cool a home.

Hello, I can assist you.

If the unit is supposed to turn off and it doesn't, it will be necessary to check several things.


  • First, is the unit cooling properly? See the section entitled "The air is cool but doesn't seem cold enough."

  • Next, is the temperature of the room adequately cool? If the room temperature is cold enough try setting the thermostat to a higher temperature. If the unit then seems to work properly leave the thermostat set to the higher temperature.

  • If the unit is cooling properly when it is turned on and the room is not cool enough the problem is probably that the unit is trying to cool an area that is too large for its capacity. Use the following chart to find the appropriate size air conditioner to use:

AREA TO BE COOLED / CAPACITY (BTU/HR)

100 to 150 square feet = 5,000

150 to 250 square feet = 6,000

250 to 300 square feet = 7,000

300 to 350 square feet = 8,000

350 to 400 square feet = 9,000

400 to 450 square feet = 10,000

450 to 550 square feet = 12,000

550 to 700 square feet = 14,000

700 to 1000 square feet = 18,000

If the room is heavily shaded, reduce needed capacity by 10%

If the room receives a lot of direct sun, increase needed capacity by 10%

Add 600 Btu/Hr for each person in the room if there are more than two people

If the unit is for a kitchen, increase the capacity by 4,000-6,000 Btu/Hr.

If the room size is too big for the air conditioner you have two possible choices. Either decrease the room size by shutting some doors or partitioning off an area of the room. Or, increase the BTU of the air conditioner for that room by installing a different air conditioner with a higher BTU rating.

The 10,000 BTU portable room a/c unit is not running cold enough


Make sure your vent is closed. check the filter to see if its clean. If you run the a/c you can check your evaporator to see if you have condensation or does it freeze up?
Make sure you have your unit on early in the morning. If you turn it on in the afternoon the humidity might be too much and it will take along time to cool down.
Try those things if that doesnt work then you need a service call.

The unit may not be big enough. From the model number I am thinking you a/c is a 12000 btu. Which is usally enough for a large room. However if you have an open floor plan or a really large room you may need a bigger or second unit.

Trru the Wall Oversized


Drop in a Frigidaire 25,000 btu, 230-volt Electronic Control Air Conditioner (Model #FAS256R2A). It is Way More Cooling than you need, but it is a very efficient unit and will provide quiet, nearly instantaneous room temprature reduction! Width 26-1/2... Height 18-5/8... Wall Sleeve Included... about $450.
