The YORK® multi-split system allows you to connect up to five indoor units [1] to a single outdoor unit, reducing the need to place equipment outside your premises. Multi-split systems offer a more efficient solution than using multiple mono-split systems, which require one outdoor unit for each indoor unit. They provide more outdoor space and minimize the visual impact on the outside. Our extensive range, which encompasses models with a capacity of 18,000 to 42,000 BTU, is designed to meet the diverse needs of our customers.
