• While under-sized air conditioners will run continuously, without effectively cooling your house, over-sized equipment will consume more energy than required increasing your electric bills.

• The first task involves measuring the dimensions (length and width and not height) and calculating floor space area of each of the rooms in your house that you plan to cool with the air conditioner.

• Now add together areas of your rooms to get total floor space area.

• Multiply this amount by 337 to get amount of heat required, which is expressed in BTUs (British Thermal Units).

• Now calculate the total area of your windows at south side (width X height) and multiply the answer by 871 to get the amount of heat that enters your house from south side.

• Now calculate the total area of your windows at north side (width X height) and multiply the answer by 166 to get the amount of heat that enters your house from north side.

• Now take the number of persons staying in house/office and calculate the heat generated by them every hour by multiplying the number by 400.

• You need to take light sources into account and in this case, the heat generated can be calculated by multiplying total watts by 4.25.

• The same goes with any other electrical appliance. The only difference is the multiplying factor in such cases is 3.15

• Add all the above figures plus 2000 BTUs (for the heat generated in your kitchen) and you will get total amount of heat that is required to remove in BTUs.

• You can now convert BTUs. into KWh or tonnage capacity to indentify your need in tonnage capacity. One ton capacity means capability of removal of 12000 BTUs.
