Calculators

Cooling rooms in your home can take a lot of evergy. It is always important to make sure you purchase an air conditioner that is the appropriate size for the space you are trying to cool. When you use an air conditioner that is to small you are not cooling your room very efficently. If you are using one that is to large your are wasting energy and throwing money away. Use this calculator below and get the approximate number of BTUs (British Thermal Units) you need to cool your room.

This calculator is designed to give an approximate size for an adequate room air conditioner unit capable of cooling the room you have described in your entry. Select entries from the drop data boxes for the room size and amount of room insulation. Select yes or no values for DIRECT sun exposure and if the room is a kitchen. Morning sun exposure is not usually a problem, however afternoon sun exposure often adds up to 15 degrees to a room. Our selection of a kitchen is based on added heat potential to a room. You may wish to try both selection if you are in question to see if there is a change in the suggested cooling required. If you are on the borderline of two potential units and there is no major price difference, we suggest the larger cooling capacity.
