550 to 700 squarre feet will need approximately 14,000 BTU's
The proper unit for any area you may be planning to cool depends on many things. Room size, insulated ceiling, other air conditioning, number of windows, and the location (morning, evening sunlight). Decide if you just want to cool one room such as a bedroom or the whole house, then take your room or home area dimensions to Home Depot and they will help you find the right size unit or units.
3 key considerations:
1. will it fit in the window/wall
2. will the plug reach & is it the proper voltage?
3. size of the room?
The function of an air conditioner is to cool the room to a comfortable temperature and remove humidity.
Installing a much larger unit than a room requires will result in the compressor running for short periods of time and being off long periods of time. As cold air leaves the air conditioner in a small room it is deflected off the walls back to the air conditioner and pre-maturely cycles the unit off resulting in cold spots and hot spots and very little loss of humidity. The ideal is to size the air conditioner so it is forced to run 80 to 100% of the time to keep the room cool. This ensures proper removal of humidity. A comfortable room is more a factor of low humidity than low temperature.
I hope this helps.
