Zone and Head Combinations
*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.

5-Year Manufacturer Warranty

Both the Compressor and the Parts
The Free Match multi-zone system comes with a standard 5-year warranty for both the compressor and parts. Our professional support team will assess your case and either cover your repair costs or provide free replacement parts, depending on the situation.
