*It's important to note that the indoor BTU range should typically be within 100% to 125% of the total BTUs (British Thermal Units) of the outdoor condenser unit in an HVAC system. For example, for a 24K BTU outdoor unit, the total BTUs of the indoor units added together should be between 24-30K BTUs. This range ensures optimal efficiency and performance of the system. If the indoor capacity is lower or higher than this standard range, it can lead to reduced efficiency and potentially other issues with the system's operation.
