Calculate the area of the room to be cooled
The first step in calculating the BTUs that your room require is by calculating the square area of the room to be cooled. For rectangular and square rooms, multiply the length by its width (all units in square footage). For the triangular parts, multiply the length with it width and then divide by two. If the shape of your room is not triangular, rectangular or square, it is very wise to get professional air conditioner services provider to help you determine the size of your room and ultimately the BTUs that your room requires.

Upon getting room square footage, you need to calculate the BTUs that you need. The following chart has been designed by professionals to aid in determining the BTUs requires.
Area to be cooled the BTUs per hour required
100 ft2 up to 150 ft2 5000 BTUs per hour
150 ft2 up to 250 ft2 6000 BTUs per hour
250 ft2 up to 300 ft2 7000 BTUs per hour
300 ft2 up to 350 ft2 8,000 BTUs per hour
350 ft2 up to 400 ft2 9,000 BTUS per hour 
400 ft2 up to 450 ft2 10,000 BTUs per hour
450 ft2 up to 550 ft2 12,000 BTUs per hour
550 ft2 up to 700 ft2 14,000 BTUs per hour
700 ft2 up to 1,000 ft2 18,000 BTUs per hour
1000 ft2 up to 1200 ft2 21,000 BTUs per hour
1200 ft2 up to 1400 ft2 23,000 BTUs per hour
1400 ft2 up to 1500 ft2 24,000 BTUs per hour
1500 ft2 up to 2,000 ft2 30,000 BTUs per hour
2,000 ft2 up to 2,500 ft2 34,000 BTUs per hour

Make adjustment
Those are the ideal BTUs that professional recommend. After calculating, you also need to consider some other factors and make the necessary adjustments. The following are some of the adjustments that you should make.If your room is heavily shaded, professional recommend that you lower the BTUs by 10 percent. This is because your room will partly cooled by the shade.If you are in a very sunny place, or your room is heavily sunny, you should increase the BTUs by 10 percent.If the air conditioner is used in the kitchen, you should increase the capacity by 4,000 BTUs.
If more than two people occupy the room, you should add 600 BTU for each additional person.

You should also look at the place where you will mount your air conditioner. If you mount it at the corner of your room, use aircon unit that will send airflow in the right direction.
