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.
