The BTU loads provided here are for general guidance only and are not guaranteed to be 100% accurate or complete. Various factors, such as ceiling height, sunlight exposure, room insulation, occupancy, and local climate, can significantly impact these values. For example, rooms with more windows or higher ceilings may require additional BTUs, and geographic location can also affect the cooling or heating needs of your space. To ensure precise measurements and optimal efficiency for your specific situation, we strongly recommend consulting a licensed engineer for a professional site inspection and calculation of the ideal air conditioner size for your space.
