Cooling BTU Calculator
British Thermal Units (BTUs) are a measurement of energy required to change temperature, frequently used when discussing HVAC. Modern air conditioner (AC) manufacturers use BTUs to make it easier to compare AC units with different capacities and designs. In general, the larger the number of BTUs, the higher the cooling capacity. Use the following calculator to understand how many BTUs are needed to cool your indoor space.
